Description
本發明關於可在內藏非接觸式IC讀卡機的智慧型手機,追加指紋認證功能之智慧型手機用之附指紋認證功能的非接觸式IC卡讀取輔助電路。The present invention relates to a non-contact IC card reading auxiliary circuit with a fingerprint authentication function for a smart phone that can have a built-in non-contact IC card reader and a fingerprint authentication function.
近年來在各種領域中使用智慧型手機。為了防止他人所致之智慧型手機的不當使用,智慧型手機具備本人確認功能。例如,以他人無法使用之方式,在從操作開始經過一定時間的狀況等鎖定而讓操作無法進行。為了解除鎖定而需要確認本人。在透過智慧型手機進行各種支付時為了確認本人,會要求輸入4位數的號碼。進行指紋認證或臉部認證等。In recent years, smartphones have been used in various fields. In order to prevent improper use of the smartphone by others, the smartphone has an identity verification function. For example, it may be locked in a way that prevents others from using it, and a certain period of time has elapsed from the start of the operation, making the operation impossible. In order to unlock, you need to confirm your identity. In order to verify your identity when making various payments via your smartphone, you will be asked to enter a 4-digit number. Perform fingerprint authentication or face authentication, etc.
智慧型手機具有世界性廣大市佔率的美國蘋果公司的iPhone(註冊商標),過去內藏有確認本人的指紋認證功能。但是,iPhone的最新機種除了一部分低價格款式之外,並未內藏指紋認證功能。iPhone的最新機種僅內藏臉部認證功能。The iPhone (registered trademark) of the American company Apple, which has the largest market share of smartphones in the world, used to have a built-in fingerprint authentication function to confirm the identity of the user. However, the latest iPhone models, except for some low-price models, do not have built-in fingerprint authentication functions. The latest iPhone models only have facial authentication built-in.
臉部認證功能被指摘依據臉部認證機制的特性之以下問題。亦即,即使與本人外觀不同,也有誤將親戚等特徵相近的人物認證為本人的可能性。作為前幾年起之新冠病毒的感染預防,尤其在日本日常會進行戴上口罩的智慧型手機操作。戴上口罩的話會讓臉部認證變難。臉部認證功能由於具有此種缺點,有對智慧型手機,除了臉部認證之外,更可使用指紋認證功能的強烈要求。The face authentication function has been criticized for the following problems based on the characteristics of the face authentication mechanism. In other words, even if the appearance is different from that of the person, there is a possibility that a person with similar characteristics, such as a relative, may be mistakenly identified as the person. As a precaution against COVID-19 infection in the past few years, especially in Japan, people wearing masks are used to operate smartphones on a daily basis. Wearing a mask will make facial authentication difficult. Because the face authentication function has such shortcomings, there is a strong demand for smartphones that can use fingerprint authentication functions in addition to face authentication.
[發明所欲解決之課題][Problem to be solved by the invention]
如果是個人電腦(PC)的話,容易透過附加來追加指紋認證裝置。但是,PC用的附加指紋認證裝置的話,因為尺寸或介面的關係,難以附加至小型攜帶終端即智慧型手機。If it is a personal computer (PC), it is easy to add a fingerprint authentication device by attaching it. However, it is difficult to attach a fingerprint authentication device for a PC to a small portable terminal such as a smartphone due to size or interface.
即使開發智慧型手機專用的指紋認證裝置,也難以成為與內藏型的指紋認證裝置同等的使用便利性。亦即,為了對指紋認證裝置的電力供給及與智慧型手機的通訊,與智慧型手機的外部介面有線連接的話,不僅纜線變成阻礙,智慧型手機本身的使用處理也會變難。又,為了將外部介面使用於其他裝置或對智慧型手機充電,卸下指紋認證裝置的話,在需要指紋認證裝置時無法馬上使用。Even if a fingerprint authentication device dedicated to smartphones is developed, it will be difficult to achieve the same ease of use as a built-in fingerprint authentication device. That is, if the power supply of the fingerprint authentication device and the communication with the smartphone are wired to the external interface of the smartphone, not only the cable will become an obstacle, but also the use and handling of the smartphone itself will become difficult. In addition, if the fingerprint authentication device is removed in order to use the external interface with other devices or charge the smartphone, the fingerprint authentication device cannot be used immediately when needed.
如公知般,近年來根據進一步強化安全防護的觀點,被要求組合了複數認證功能的多重要素認證所致之認證。又,因為被稱為SIM卡交換(劫持)攻擊之讓智慧型手機內藏的臉部認證及指紋認證無效化的新方法,國外發生高額的損害事件,可預測今後在日本國內損害會急遽增加。作為緊迫的課題,要求對於SIM卡交換攻擊也有效的生物識別裝置。As is known, in recent years, from the viewpoint of further strengthening security protection, authentication by multi-factor authentication that combines multiple authentication functions has been required. In addition, due to a new method called SIM swapping (hijacking) attack that invalidates facial authentication and fingerprint authentication built in smartphones, high-cost damage incidents have occurred abroad, and it is expected that damage will be rapid in Japan in the future. Increase. As an urgent issue, biometric identification devices that are effective against SIM card swapping attacks are required.
作為生物識別裝置而使用附指紋認證功能的非接觸式IC卡,想要透過智慧型手機使用指紋認證功能時,僅利用所安裝的應用程式軟體的話無法從非接觸式IC讀卡機對線圈進行連續之供電的智慧型手機中,即使讓附指紋認證功能的非接觸式IC卡動作,也僅在被認證為相同的指紋時,從IC晶片對非接觸式IC讀卡機進行NFC通訊的卡中,無法從非接觸式IC讀卡機進行連續的供電,無法讓指紋對照完成。因此,無法透過智慧型手機,使用附指紋認證功能的非接觸式IC卡的指紋認證功能。When a non-contact IC card with a fingerprint authentication function is used as a biometric device, and you want to use the fingerprint authentication function with a smartphone, you cannot use the installed application software to read the coil from the contactless IC card reader. In a continuously powered smartphone, even if a contactless IC card with a fingerprint authentication function is activated, the card will only perform NFC communication from the IC chip to the contactless IC card reader when the same fingerprint is authenticated. , continuous power supply cannot be provided from the contactless IC card reader, and the fingerprint comparison cannot be completed. Therefore, the fingerprint authentication function of a contactless IC card with fingerprint authentication function cannot be used through a smartphone.
本發明的目的係提供可將與內藏於智慧型手機的指紋認證裝置同等的使用便利性,附加於智慧型手機之智慧型手機用之附指紋認證功能的非接觸式IC卡讀取輔助電路。本發明的進一步目的係提供可對應組合了複數認證功能之多重要素認證,且對於SIM卡交換攻擊也有效之智慧型手機用之附指紋認證功能的非接觸式IC卡讀取輔助電路。 [用以解決課題之手段] An object of the present invention is to provide a non-contact IC card reading auxiliary circuit for a smartphone with a fingerprint authentication function that can be added to a smartphone with the same ease of use as a fingerprint authentication device built in a smartphone. . A further object of the present invention is to provide a non-contact IC card reading auxiliary circuit for a smartphone with a fingerprint authentication function that can handle multi-factor authentication that combines multiple authentication functions and is also effective against SIM card swapping attacks.

Continuous power supply to the coil, To complete the aforementioned fingerprint authentication caused by the aforementioned fingerprint authentication department, The aforementioned fingerprint authentication notification is performed when the aforementioned fingerprint authentication is successful.
本發明相關之附指紋認證功能的非接觸式IC卡讀取輔助電路適用於僅利用應用程式軟體的話,無法進行從前述非接觸式IC讀卡機對線圈之連續的供電的智慧型手機。在藉由輔助電路的第2線圈從非接觸式IC讀卡機接收電力時,透過NFC通訊的初期反應,辨識NFC晶片。藉由該辨識,成為可進行從非接觸式IC讀卡機對線圈之連續的供電,而開始指紋認證。在被認證為相同的指紋時,非接觸式IC讀卡機從IC晶片接收指紋認證通知。如此,安裝附指紋認證功能的非接觸式IC卡讀取輔助電路,進行指紋認證,將被認證為相同的指紋一事傳達給智慧型手機,藉此不需有線連接即可在智慧型手機使用指紋認證功能。The non-contact IC card reading auxiliary circuit with fingerprint authentication function related to the present invention is suitable for smart phones that cannot continuously supply power to the coil from the non-contact IC card reader using only application software. When receiving power from the contactless IC card reader through the second coil of the auxiliary circuit, the NFC chip is recognized through the initial response of NFC communication. Through this recognition, it becomes possible to continuously supply power to the coil from the contactless IC card reader, and start fingerprint authentication. When being authenticated to the same fingerprint, the contactless IC card reader receives a fingerprint authentication notification from the IC chip. In this way, a non-contact IC card reading auxiliary circuit with a fingerprint authentication function is installed, fingerprint authentication is performed, and the fact that the fingerprint is authenticated as the same fingerprint is notified to the smartphone, so that the fingerprint can be used on the smartphone without a wired connection. Authentication function.
智慧型手機用之附指紋認證功能的非接觸式IC卡讀取輔助電路的電路基板及指紋感測器、指紋認證部、記憶體、線圈等之進行指紋認證的指紋認證功能電路基板由於可由非常薄的印刷電路基板所構成,即使組入智慧型手機用手機殼,厚度也幾乎不會增加地安裝,指紋認證功能電路基板藉由透過塑膠的薄板層合兩面,也可加工成IC卡形狀而作為附指紋認證功能的非接觸式IC卡。又,可藉由NFC而以無線連接動作,故可提供與內藏的指紋認證裝置同等的使用便利性。The circuit board of the non-contact IC card reading auxiliary circuit with fingerprint authentication function for smartphones and the fingerprint authentication function circuit board of the fingerprint sensor, fingerprint authentication unit, memory, coil, etc. can be used for fingerprint authentication. It is composed of a thin printed circuit board and can be installed with almost no increase in thickness even when incorporated into a smartphone case.

近年來,智慧型手機的非接觸式IC讀卡機不僅讀卡,也需要進行電子錢的支付等而與各式各樣的外部機器進行通訊。在本發明的實施例中,僅在被認證為相同的指紋時,會使內藏於附指紋認證功能的非接觸式IC卡或指紋認證功能電路基板之進行NFC通訊的IC晶片動作,所以,手指不接觸指紋感測器的話,進行NFC通訊的IC晶片也不會動作。In recent years, contactless IC card readers for smartphones are not only required to read cards, but also to communicate with various external devices such as payment of electronic money. In the embodiment of the present invention, only when the same fingerprint is authenticated, the IC chip for NFC communication built in the non-contact IC card with the fingerprint authentication function or the fingerprint authentication function circuit board is activated. Therefore, If your finger does not touch the fingerprint sensor, the IC chip for NFC communication will not operate.

[實施例][Example]
圖1係關聯於本發明之指紋認證系統的區塊圖。本案發明者最初考量將指紋認證功能內藏於智慧型手機用手機殼,透過NFC連接。圖中,參照符號1為智慧型手機用的附指紋認證功能手機殼。2為靜電容式之薄型形狀的指紋感測器。3為指紋認證部。4為保存對照用指紋資料的記憶體。5為從非接觸式IC讀卡機接收電力的線圈。6為具有進行NFC通訊之功能的IC晶片,典型上來說為FeliCa(註冊商標)晶片。參照符號7表示進行了指紋登記之使用者的手指。8為智慧型手機。於智慧型手機8安裝智慧型手機用的附指紋認證功能手機殼1。參照符號9為內藏於智慧型手機8的非接觸式IC讀卡機。FIG. 1 is a block diagram related to the fingerprint authentication system of the present invention. The inventor of this case initially considered embedding the fingerprint authentication function in a smartphone case and connecting it through NFC. In the figure,
在圖1之本發明的實施例中,圖示的指紋認證系統中,搭載於智慧型手機用的附指紋認證功能手機殼1的裝置,亦即指紋感測器2、指紋認證部3、保存對照用指紋資料的記憶體4、線圈5、IC晶片(FeliCa晶片6)構成指紋認證手段Fp。在指紋認證手段Fp中,以從內藏於智慧型手機8的非接觸式IC讀卡機9對於線圈5進行供電一事作為條件,接受供電的線圈5對指紋感測器2、指紋認證部3、記憶體4等供給電力,然後開始指紋認證。此時,指紋認證部3以藉由停止對FeliCa晶片6的供電等的方法,讓FeliCa晶片6不動作的方式控制FeliCa晶片6。In the embodiment of the present invention in Figure 1, the fingerprint authentication system shown in the figure is equipped with a device equipped with a fingerprint authentication function
開始指紋認證後,預先指紋登記的手指7接觸指紋感測器2的話,指紋認證部3會對照從指紋感測器2讀取之手指7的指紋資料與保存於記憶體4的對照用指紋資料。藉由該對照而被認證為相同的指紋的話,則以讓FeliCa晶片6動作之方式控制FeliCa晶片6。藉此,非接觸式IC讀卡機9成為可讀取出FeliCa晶片6的IDm資料的狀態。此狀態維持到對線圈5的供電停止為止。After starting the fingerprint authentication, if the
另一方面,指紋認證前或未被認證為相同的指紋時,指紋認證部3則以不讓FeliCa晶片6動作之方式進行控制,維持IDm資料不讓讀取的狀態。藉由上述的控制,FeliCa晶片6的IDm資料僅在被認證為相同的指紋時,變成可透過非接觸式IC讀卡機9讀取。換句話說,未被認證為相同的指紋時,FeliCa晶片6的IDm資料無法透過非接觸式IC讀卡機9讀取。On the other hand, before fingerprint authentication or when the same fingerprint has not been authenticated, the
IDm資料係為FeliCa晶片的製造時所記錄之固有的ID號碼。IDm資料無法改寫。因此,相同IDm資料的FeliCa晶片此外並不存在。以僅限於滿足第1:可透過非接觸式IC讀卡機9讀取FeliCa晶片6的IDm資料,又,第2:事先登記於智慧型手機8的IDm資料與FeliCa晶片6的IDm資料一致的2個條件時,可利用智慧型手機8辨識「透過智慧型手機用的附指紋認證功能手機殼1指紋認證成功」之方式構成。此時,在智慧型手機8中,變成透過指紋與FeliCa的IDm資料的雙重認證,相較於僅指紋之單純的指紋認證,可提供更高的安全防護。The IDm data is the unique ID number recorded during the manufacturing of FeliCa wafers. IDm data cannot be rewritten. Therefore, no other FeliCa wafer with the same IDm data exists. It is limited to those that satisfy the first requirement: the IDm data of the
於圖1所圖示的指紋認證系統中,作為在與非接觸式IC讀卡機9之間進行NFC(Near Field Communication)的通訊的IC晶片,使用FeliCa晶片6。例如,非接觸式IC讀卡機9係支援NFC規格的無線通訊,所以,只要是可進行NFC通訊的IC晶片,使用Mifare(註冊商標)等之其他NFC規格的IC晶片亦可。In the fingerprint authentication system illustrated in FIG. 1 , a
於圖1所圖示的指紋認證系統中,作為指紋認證部3在「被認證為相同的指紋」時之對非接觸式IC讀卡機9的通知方法,透過設為可讀取IDm資料的狀態來實現。作為變形例,設為可讀取其他資料、或IDm與其他資料的組合狀態亦可。In the fingerprint authentication system illustrated in FIG. 1, as a method of notifying the
前述通知方法的實現方法也可單純地透過藉由來自非接觸式IC讀卡機9的所定指令,指紋認證部3認證為相同的指紋時,FeliCa晶片6發送所訂定的資料而非接觸式IC讀卡機9接收來實現。但是,透過某些其他手段對讀卡機9發送與前述訂定的資料相同的資料,即使指紋認證部3未認證為相同的指紋,也被作為當作「被認證為相同的指紋」而突破安全防護的方法被不當使用之虞,需要注意該不當使用。The aforementioned notification method can also be implemented simply by using a predetermined command from the contactless
針對該不當使用,例如將登記了其他指紋的其他智慧型手機用的附指紋認證功能手機殼1安裝於智慧型手機8時,為了防止智慧型手機側當作「被認證為相同的指紋」而動作一事,採取讓智慧型手機用的附指紋認證功能手機殼1側持有固有的資料,將與被登記於智慧型手機8側的資料一致作為指紋認證成功之追加的必要條件等的對策為佳。In response to this improper use, for example, when a
於圖1所圖示的指紋認證系統中,前述通知方法透過發送FeliCa晶片6的IDm資料來實現。如上所述,並不存在相同IDm資料的FeliCa晶片,故如前述般難以不進行指紋認證就突破安全防護。亦即,使用某些手段,讓智慧型手機8側辨識「被認證為相同的指紋」而突破安全防護實際上很困難。In the fingerprint authentication system illustrated in FIG. 1 , the aforementioned notification method is implemented by sending the IDm data of the
IDm在一般的安全卡的認證中被採用,現在並未發生較大的問題。但是,也有IDm公開通訊方法等,有可能偽造的意見。在一般的FeliCa卡也有IDm資料被簡單地透過略讀(skimming)讀取的問題。在圖1所圖示的指紋認證系統中,以僅在指紋認證部3認證為相同的指紋時,可讀取出IDm資料的方式進行控制。藉此,只要不被認證為相同的指紋,也不可能進行略讀,故可大幅減少略讀的風險。IDm is used for general security card authentication, and no major problems have occurred so far. However, there is also an opinion that it is possible to forge the IDm public communication method, etc. In general FeliCa cards, there is also a problem that IDm data is simply read through skimming. In the fingerprint authentication system shown in FIG. 1 , control is performed so that the IDm data can be read only when the
作為FeliCa卡的IDm偽造對策,提案有在FeliCa Lite-S晶片中進行秘密金鑰所致之MAC認證的方法、在FeliCa Standard晶片中利用安全區域的方法等。可將此種方法適當適用於圖1所圖示的指紋認證系統的前述通知方法。As countermeasures against IDm counterfeiting of FeliCa cards, proposals include a method of performing MAC authentication using a secret key in the FeliCa Lite-S chip, and a method of utilizing a security area in the FeliCa Standard chip. This method can be appropriately applied to the aforementioned notification method of the fingerprint authentication system illustrated in FIG. 1 .
在圖1所圖示的指紋認證系統中,以開始來自非接觸式IC讀卡機9的供電的話,到指紋認證部3認證為相同的指紋為止,進行NFC通訊的IC晶片(FeliCa晶片6)不動作之方式進行控制。藉此,在(i)透過內藏於智慧型手機8的非接觸式IC讀卡機9讀取其他非接觸式IC卡的狀況、(ii)內藏於智慧型手機8的非接觸式IC讀卡機9在電子錢的支付等之與各式各樣的外部機器之間進行NFC通訊的狀況中,即使成為也對於智慧型手機殼1內的線圈5供電的狀態,也以不會藉由指紋認證部3,讓進行NFC通訊的IC晶片(FeliCa晶片6)動作之方式進行控制。藉由不讓該IC晶片(FeliCa晶片6)動作的控制,可防止妨礙非接觸式IC讀卡機9的NFC通訊。In the fingerprint authentication system shown in FIG. 1 , when the power supply from the non-contact
所以,在未被指紋認證的狀態下,智慧型手機8可毫無問題地使用於使用內藏於其的非接觸式IC讀卡機9的各種用途。在使用非接觸式IC讀卡機9的各種用途中,不需要從智慧型手機8卸除智慧型手機用的附指紋認證功能手機殼1。內藏於智慧型手機8的非接觸式IC讀卡機9欲在指紋認證成功之後在與電子錢的支付等的各種外部機器之間進行NFC通訊時,智慧型手機8辨識「被認證為相同的指紋」之後,可藉由一旦停止來自非接觸式IC讀卡機9的供電,讓智慧型手機殼1內之進行NFC通訊的IC晶片(FeliCa晶片6)不動作。Therefore, without fingerprint authentication, the
依據圖2所圖示的流程圖,說明於圖1所圖示的指紋認證系統中,藉由智慧型手機8控制內藏於智慧型手機用的附指紋認證功能手機殼1的電子電路的方法之一例。According to the flow chart shown in FIG. 2 , in the fingerprint authentication system shown in FIG. 1 , the
啟動安裝於智慧型手機8的應用程式軟體的話,在最初的步驟S1中於圖1的智慧型手機8的顯示器顯示「請碰觸指紋感測器」的訊息,然後,啟動內藏計時器(S2)。於該軟體中,開啟輪詢(polling)的指令被發送至非接觸式IC讀卡機9(S3),非接觸式IC讀卡機9開始輪詢,進行對線圈5的供電。When the application software installed on the
接受供電的線圈5將電力供給至指紋感測器2、指紋認證部3、記憶體4等。藉此,開始指紋認證。該軟體係在下個步驟S4,到計時器達到0.5秒為止重複進行輪詢。輪詢執行時間係被設定為與指紋認證部3最快導出認證結果的時間同等或比其短的時間。在重複進行輪詢的狀態下,藉由調整輪詢指令的參數等,將1次輪詢中供電的時間設定為某種程度的長度為佳。藉此,可成為連續供電的狀態。The
於步驟S6中,讀取IDm資料的指令被發送至非接觸式IC讀卡機9。非接觸式IC讀卡機9係將IDm資料的讀取成功或失敗,回送至該軟體。In step S6, an instruction to read IDm data is sent to the contactless
如前述般,FeliCa晶片6的IDm資料僅在指紋認證部3認證為相同的指紋時,變成可透過非接觸式IC讀卡機9讀取。在IDm資料的讀取成功時,比較事先登記於智慧型手機8的資料與所讀取的IDm資料(S7),在一致時,對智慧型手機8內的系統通知「智慧型手機用的附指紋認證功能手機殼1中指紋認證成功」(S8)。As mentioned above, the IDm data of the
另一方面,於步驟S7中,在IDm資料不一致時,非接觸式IC讀卡機9則判斷為讀取了其他FeliCa卡的IDm資料。然後,對智慧型手機8內的系統通知「智慧型手機用的附指紋認證功能手機殼1中指紋認證失敗」(S9)。在IDm資料的讀取失敗時,將再次開啟輪詢的指令發送至非接觸式IC讀卡機9,然後,作出返回IDm資料的讀取步驟的循環(S6)。On the other hand, in step S7, when the IDm data is inconsistent, the contactless
對於指紋認證部3認證指紋來說需要1~2秒鐘的運算時間。所以,循環的期間中需要設為線圈5經常可連續接收電力的狀態。為了對應該狀況,藉由調整指令的參數等,將透過對非接觸式IC讀卡機9之1次的輪詢指令進行供電的時間,設定某程度比較長的時間。所以,可設為線圈5經常可連續接收電力的狀態。It takes 1 to 2 seconds for the
於該循環中,步驟S5中計時器經過10秒鐘時,對智慧型手機8內的系統通知「智慧型手機用的附指紋認證功能手機殼1中指紋認證失敗」(S9)。將指紋認證的結果通知系統之後,關閉輪詢(S10),結束該應用程式軟體。In this loop, when the timer in step S5 elapses for 10 seconds, the system in the
智慧型手機8內的系統辨識出「指紋認證成功」時,則解除鎖定,或允許對特定網路的連接。亦即,依據圖1所圖示的指紋認證系統,可實現與內藏型的指紋認證裝置同等的使用便利性。When the system in the
圖3係構造相關的第1實施例的說明圖。圖4係其剖面圖。於圖3、圖4中,對於與圖1所圖示相同要素附加相同的參照符號。再者,圖3、圖4所圖示的參照符號10為手機殼1的外殼。參照符號11為指紋認證功能電路基板,12為貫通孔。貫通孔12設置於手機殼1的外殼10。藉由使安裝於指紋認證功能電路基板11的指紋感測器2,透過貫通孔12露出,可利用手指7碰觸指紋感測器2。FIG. 3 is an explanatory diagram of the first embodiment related to the structure. Figure 4 is its cross-sectional view. In FIGS. 3 and 4 , the same elements as those shown in FIG. 1 are assigned the same reference numerals. In addition,
參照圖3、圖4,於指紋認證功能電路基板11,線圈5由銅箔的印刷圖案形成。於指紋認證功能電路基板11,除了指紋感測器2以外搭載圖1所示的指紋認證部3、記憶體4、FeliCa晶片6等的電子零件。搭載該等電子零件的指紋認證功能電路基板11可非常容易地製造成總厚度為1毫米以下。Referring to FIGS. 3 and 4 , on the fingerprint authentication
手機殼1的外殼10需要配合智慧型手機8的各機型的形狀,如圖4的剖面圖所示,對於既有的智慧型手機用手機殼,僅安裝非常薄的指紋認證功能電路基板11及設置用以露出指紋感測器的貫通孔12。因此,可根據既有的智慧型手機用手機殼設計資料,容易地設計、製造手機殼1的外殼10。The
又,於智慧型手機8常時安裝著智慧型手機用的附指紋認證功能手機殼1的狀態下使用智慧型手機8時,需要以指紋認證功能電路基板11在面方向不移動之方式在手機殼1的外殼10的形狀上下功夫,但是,不需要將指紋認證功能電路基板11固定於手機殼1的外殼10。指紋認證功能電路基板11的面積也是由印刷圖案形成的線圈5佔據大部分,故可設計成能適用於複數智慧型手機的機型的形狀。In addition, when using the
圖1所圖示的指紋認證系統的動作係配合智慧型手機的OS,雖然應用程式軟體的原始碼不同,但指紋認證功能電路基板11本身並不相依於OS。因此,不同OS的智慧型手機也可使用相同的指紋認證功能電路基板11。所以,藉由設計可收納於各種智慧型手機用手機殼之形狀的指紋認證功能電路基板11,可大量生產相同形狀的基板而謀求成本降低。The operation of the fingerprint authentication system shown in Figure 1 is coordinated with the OS of the smartphone. Although the source code of the application software is different, the fingerprint authentication
圖5係構造相關的第2實施例的說明圖。圖6係其剖面圖。參照圖5、圖6,於指紋認證功能電路基板11,線圈5由銅箔的印刷圖案形成,又,在指紋感測器2以外搭載圖1所示的指紋認證部3、記憶體4、FeliCa晶片6等的電子零件。FIG. 5 is an explanatory diagram of the second embodiment related to the structure. Figure 6 is its cross-sectional view. Referring to FIGS. 5 and 6 , on the fingerprint authentication
搭載該等電子零件的指紋認證功能電路基板11可非常容易地製造成總厚度為1毫米以下。如圖5所示,指紋認證功能電路基板11例如作成為***尺寸的形狀。藉此,在將智慧型手機安裝於手機殼1的外殼10的狀態下,可容易裝卸***尺寸的指紋認證功能電路基板11。指紋認證功能電路基板11也可透過智慧型手機的OS以外動作。在指紋認證功能電路基板11單體的狀態下,以連接於PC的非接觸式IC讀卡機等也可使用的方式,使用一般的非接觸式IC卡的製造技術,利用塑膠薄板層合於指紋認證功能電路基板11的兩面以作為附指紋認證功能的非接觸式IC卡亦可。The fingerprint authentication
本案發明者作成適合於美國蘋果公司的iPhone之遵照圖2所圖示的流程圖之應用程式軟體,並驗證實際的動作。於近年的iPhone內藏有非接觸式IC讀卡機。以於iPhone中,適合iOS13之後的OS之方式,使用NFC規格的通訊框架即CoreNFC,作成應用程式軟體。然後,可確認到可使用iPhone內藏的非接觸式IC讀卡機,進行一般的FeliCa卡等之NFC規格的卡的讀寫。The inventor of this case created application software suitable for the iPhone of Apple Inc. in the United States and followed the flow chart shown in Figure 2, and verified the actual operation. In recent years, iPhones have built-in contactless IC card readers. In the iPhone, the application software is created using the NFC standard communication framework, CoreNFC, in a manner suitable for the OS after iOS13. Then, it was confirmed that the contactless IC card reader built into the iPhone can be used to read and write NFC-standard cards such as general FeliCa cards.
使用CoreNFC,作成遵照圖2所圖示的流程圖之iPhone用應用程式軟體,並驗證動作的時候,可確認到可進行一般的FeliCa卡、Mifare卡等之NFC規格的卡的IDm、UID的讀取。但是,對於圖1所圖示的指紋認證系統,發現到無法進行連續供電,也無法進行指紋認證及IDm的讀取的問題點。Using CoreNFC, when creating iPhone application software following the flow chart shown in Figure 2 and verifying the operation, it was confirmed that the IDm and UID of NFC-standard cards such as general FeliCa cards and Mifare cards can be read. Pick. However, with respect to the fingerprint authentication system shown in FIG. 1 , problems were discovered that continuous power supply cannot be provided, and fingerprint authentication and IDm reading cannot be performed.
在圖7揭示圖1所圖示的指紋認證系統中,啟動依據圖2所圖示的流程圖之iPhone用應用程式軟體時之對線圈5的供電狀態。圖7係第1例的時序圖。檢討上述的問題點也就是說無法進行連續供電的問題之結果,本案發明者發現原因是透過輪詢指令進行1次供電的期間在初始設定中比較短。對於此問題,即使變更CoreNFC的Polling指令等的參數之timeSlot值,想要延長進行1次輪詢的期間,實際的供電期間也不會改變。據此,由圖7可知,以一定週期重複進行對線圈5僅短時間的供電。所以,可知對於在iPhone中以圖1所圖示的指紋認證系統動作之方式而設為連續供電狀態來說,僅透過應用程式軟體無法完成。FIG. 7 shows the power supply state of the
將一般的FeliCa卡或Mifare卡等之NFC規格的卡接近iPhone內藏的非接觸式IC讀卡機9的狀態下,亦即在可進行NFC通訊的狀態下,timeSlot值的變更成為有效,也可增長供電期間。但是,在圖1所圖示的指紋認證系統中,IC晶片(FeliCa晶片6)成為可進行NFC通訊的狀態是在指紋認證成功之後。然後,供電時間無法增長的話,則指紋認證無法完成。因此,timeSlot值的變更不會變成有效,無法增長供電期間。When an NFC-standard card such as a general FeliCa card or Mifare card is brought close to the contactless
在本應用程式軟體中,在使該軟體動作的狀態下,將一般的FeliCa卡或Mifare卡等之NFC規格的卡接近內藏的非接觸式IC讀卡機9的話,會進行NFC通訊,timeSlot值的變更成為有效,實際的輪詢的期間變長而成為進行連續供電的狀態。透過設為連續供電狀態,圖1所圖示的指紋認證系統成為可進行指紋認證,在指紋認證成功後可確認成為FeliCa晶片6動作的狀態。In this application software, when the software is activated and an NFC-standard card such as a general FeliCa card or Mifare card is brought close to the built-in non-contact
然而,為了變更timeSlot值,接近非接觸式IC讀卡機9的卡是Mifare卡時,於圖1所圖示的指紋認證系統中,在指紋認證成功後,內藏的非接觸式IC讀卡機9也會讀取到Mifare卡的固有資料即UID,無法讀取FeliCa晶片6的IDm資料。本案發明者推測此係因為內藏的非接觸式IC讀卡機9最初進行與Mifare卡的NFC通訊,且欲直接維持與Mifare卡的通訊,故不會進行與FeliCa晶片6的通訊之故。However, in order to change the timeSlot value, when the card close to the contactless
對於消除此問題來說,需要以可讓內藏的非接觸式IC讀卡機9成為連續供電狀態之方式在對線圈5的供電開始後進行NFC通訊,讓timeSlot值的變更成為有效,並且在連續供電狀態下讓讀卡機可實際讀取FeliCa晶片6的IDm。In order to eliminate this problem, it is necessary to perform NFC communication after the power supply to the
進而,近年來智慧型手機的非接觸式IC讀卡機9不僅讀卡,也需要進行電子錢的支付等而與各式各樣的外部機器進行NFC通訊。在將包含於圖1所圖示的指紋認證系統的手機殼1安裝於智慧型手機8的狀態下,在透過其他應用程式軟體,非接觸式IC讀卡機9與其他IC卡進行NFC通訊之際、與包含外部之非接觸式IC讀卡機的各式各樣的外部機器進行NFC通訊之際,本發明的實施例可不妨礙地使用。Furthermore, in recent years, the contactless
在NFC通訊的規格中,非接觸式IC讀卡機與NFC卡間的通訊序列係由第1:設定非接觸式IC讀卡機與目的的NFC卡之通訊路徑的「初期反應」,與第2:進行因應應用程式的資訊之收授的「活動狀態」所構成。In the specifications of NFC communication, the communication sequence between the contactless IC card reader and the NFC card consists of the first: "initial response" of setting the communication path between the contactless IC card reader and the destination NFC card, and the second 2: It consists of "activity status" that receives and receives information corresponding to the application.
首先,透過初期反應而開始來自非接觸式IC讀卡機的供電時,NFC卡會成為等待來自非接觸式IC讀卡機的通訊路徑的設定要求(請求指令)的狀態。接著,從非接觸式IC讀卡機發送請求指令,NFC卡回送回應。藉此,辨識出存在於非接觸式IC讀卡機的通訊區域的NFC卡。之後,非接觸式IC讀卡機係在與所辨識的NFC卡之間交換參數,相互確認通訊速度等的條件。經此,從初期反應轉移至活動狀態。在活動狀態中,選擇透過初期反應所辨識的NFC卡,透過重複進行對於來自非接觸式IC讀卡機的指令之來自NFC卡的回應而進行NFC通訊。First, when the power supply from the contactless IC card reader is started through the initial response, the NFC card will be in a state of waiting for a communication path setting request (request command) from the contactless IC card reader. Then, a request command is sent from the contactless IC card reader, and the NFC card sends back a response. Thereby, the NFC card existing in the communication area of the contactless IC card reader is identified. Afterwards, the contactless IC card reader exchanges parameters with the recognized NFC card and mutually confirms conditions such as communication speed. After this, it moves from the initial reaction to the active state. In the active state, the NFC card recognized through the initial response is selected, and NFC communication is performed by repeatedly performing responses from the NFC card to commands from the contactless IC card reader.
NFC卡有Mifare卡等的類型A、日本國內的駕照等的類型B、FeliCa卡的類型F等,初期反應中同時存在複數相同類型的NFC卡時的處理方法對應各類型而訂定。在存在複數NFC類型的卡時,可藉由指定讀取之卡的類型,僅辨識所指定之類型的卡。在指定複數類型時,可辨識所指定之複數類型的卡。但是,例如同時辨識Mifare卡與FeliCa卡時,有比FeliCa卡的IDm會更優先讀取Mifare卡的UID等之未明確記載於NFC通訊的規格的限制。NFC cards include Type A such as Mifare cards, Type B such as Japanese driver's licenses, and Type F FeliCa cards. In the initial response, the handling method when multiple NFC cards of the same type exist at the same time is determined for each type. When there are multiple NFC types of cards, you can specify the type of card to be read and only the specified type of card will be recognized. When specifying multiple types, cards of the specified plural types will be recognized. However, for example, when a Mifare card and a FeliCa card are recognized at the same time, there are limitations that are not clearly stated in the NFC communication specifications, such as the UID of the Mifare card being read prior to the IDm of the FeliCa card.
Mifare卡等的類型A的卡係採用(i)在初期反應之際辨識出複數Mifare卡時透過被稱為比特衝撞方式的方式,讀入所有辨識出之Mifare卡的UID,接著,(ii)非接觸式IC讀卡機指定所讀入的UID之一,(iii)透過UID一致的Mifare卡回應,從複數Mifare卡中選擇其一的方式。所以,無法辨識初期反應中未回應的Mifare卡。Type A cards such as Mifare cards use (i) a method called bit collision when multiple Mifare cards are recognized during the initial response, and read the UIDs of all recognized Mifare cards, and then (ii) The contactless IC card reader specifies one of the UIDs read in, (iii) responds through a Mifare card with the same UID, and selects one of the multiple Mifare cards. Therefore, the Mifare card that did not respond in the initial response cannot be recognized.
(i)在FeliCa卡中知道IDm時指定IDm,IDm一致的FeliCa卡進行回應的方法,(ii)複數FeliCa卡的系統碼不同時,即使重疊卡片也可指定系統碼而讀取對應之FeliCa卡的IDm資料。可確認到初期反應時為了變更timeSlot值,將接近非接觸式IC讀卡機9的FeliCa卡,變更為與包含於圖1所圖示的指紋認證系統之FeliCa晶片6的系統碼不同的FeliCa卡時,指紋認證成功後即使維持FeliCa卡不動,內藏的非接觸式IC讀卡機9也可藉由指定手機殼1側之FeliCa晶片6的系統碼,讀取FeliCa晶片6的IDm資料。進行了初期反應的FeliCa卡可確認到因為是與FeliCa晶片6不同的系統碼,所以,其IDm是無法讀取的狀態,但成為連續供電狀態。(i) When the IDm is known in the FeliCa card, specify the IDm, and the FeliCa card with the same IDm will respond. (ii) When the system codes of multiple FeliCa cards are different, even if the cards overlap, the system code can be specified and the corresponding FeliCa card can be read. IDm information. It was confirmed that in order to change the timeSlot value during the initial reaction, the FeliCa card close to the contactless
在內藏於iPhone的非接觸式IC讀卡機9中,透過初期反應辨識出某些NFC卡的話則timeSlot值的變更成為有效。但是,對於為了在維持連續供電狀態而指紋認證成功後,可從智慧型手機用的附指紋認證功能手機殼1側之具有NFC通訊的功能的IC晶片(FeliCa晶片6),對非接觸式IC讀卡機9通知指紋認證成功一事來說,需要完美組合透過初期反應辨識之NFC卡功能的控制時序、NFC晶片的種類、智慧型手機用的附指紋認證功能手機殼1側之具有NFC通訊的功能的IC晶片之NFC的種類。In the contactless
在圖8揭示圖1所圖示的指紋認證系統中,啟動依據圖2所圖示的流程圖之iPhone用應用程式軟體時之對線圈5的供電狀態。圖8係第2例的時序圖。參照圖8,為了讓timeSlot值的變更成為有效而對線圈5供電的話,從該供電開始稍微延遲而讓FeliCa晶片6變成可在短時間內動作的狀態。藉此,對線圈5供電的話在初始設定短的輪詢期間內,在內藏的非接觸式IC讀卡機9與FeliCa晶片6之間進行NFC通訊的初期反應,timeSlot值的變更成為有效。因此,實際的輪詢的期間變長,成為進行連續供電的狀態。FIG. 8 shows the power supply state of the
在圖8的第2例的時序圖中,對線圈5的供電後稍微延遲而使FeliCa晶片6成為動作狀態,但同時成為動作狀態亦可。設置延遲時間是因為在(i)啟動該軟體以外的應用程式軟體,透過非接觸式IC讀卡機9讀取NFC卡的狀況、(ii)內藏於智慧型手機8的非接觸式IC讀卡機9因為電子錢的支付等而與外部機器進行NFC通訊的狀況等中,以不發生妨礙的方式,延遲辨識FeliCa晶片6的順序之故。In the timing chart of the second example in FIG. 8 , the
在圖8的第2例的時序圖中重要的是在開始線圈供電,FeliCa晶片6透過初期反應被辨識之後,一旦停止FeliCa晶片6。該應用程式軟體係由圖2所圖示的流程圖可知,開始線圈供電後到0.5秒鐘為止,並未進行IDm的讀取。在該期間中,即使讓FeliCa晶片6短時間成為動作狀態,也不會影響本應用程式軟體的動作。在此軟體中,開始線圈供電經過0.5秒鐘之後,進行IDm的讀取。因為在指紋認證部3最短出現認證結果的時間之前,所以,在其以前藉由一旦停止FeliCa晶片6,該軟體可透過讀取FeliCa晶片6的IDm,將指紋認證成功一事確實地通知智慧型手機8內的系統。What is important in the timing chart of the second example in FIG. 8 is that after the coil power supply is started and the
在圖8的第2例的時序圖中,控制手機殼1側之具有NFC通訊的功能的IC晶片。因此,IC晶片不是FeliCa晶片亦可。即使是其他NFC晶片,也一旦停止初期反應時所辨識的NFC晶片,在指紋認證成功後再次作為動作狀態而通知指紋認證成功,所以可毫無問題地動作。但是,如圖8的第2例的時序圖般動作時,手機殼1側之具有NFC通訊的功能的IC晶片藉由外部的非接觸式IC讀卡機的供電而動作,假設即使指紋認證未成功,也變成可進行通訊,結果,變成可進行簡單地透過外部的非接觸式IC讀卡機讀取固有資料等的略讀,故有安全防護變弱的可能性。In the timing diagram of the second example in FIG. 8 , the IC chip with NFC communication function on
在圖9揭示圖1所圖示的指紋認證系統中,啟動依據圖2所圖示的流程圖之iPhone用應用程式軟體時之對線圈5的供電狀態。圖9係第3例的時序圖。參照圖9,為了讓指紋認證成功之際動作的FeliCa晶片6的IDm即使指紋認證未成功時,也不能透過外部的非接觸式IC讀卡機讀取,將透過初期反應辨識之其他的NFC晶片追加至手機殼1內。然後,供電至線圈5的話,則稍微延遲而讓其他NFC晶片成為僅短時間可動作的狀態。FIG. 9 shows the power supply state of the
其他NFC晶片是FeliCa晶片的話,不存在相同的IDm的晶片,故指紋認證未成功的話,可透過外部的非接觸式IC讀卡機讀取的IDm不同於FeliCa晶片6的IDm。因此,可保持安全防護。又,透過初期反應辨識出FeliCa晶片的話,之後,不僅2個FeliCa晶片的系統碼不同的狀況,同時動作的FeliCa晶片是1個的話,即使其他FeliCa晶片的系統碼與FeliCa晶片6的系統碼相同的狀況中,也可在轉移至活動狀態之後進行NFC通訊。因此,即使將2個低價格的FeliCa Lite-S晶片安裝於智慧型手機用的附指紋認證功能手機殼1內,也只要以2個晶片不同時動作之方式控制的話,即可毫無問題地動作。If the other NFC chips are FeliCa chips, there is no chip with the same IDm. Therefore, if the fingerprint authentication fails, the IDm that can be read by an external contactless IC card reader is different from the IDm of the
進而,僅利用將智慧型手機8接近外部的非接觸式IC讀卡機,即使不進行指紋認證也可發送其他IDm,故在安全防護並不嚴格的用途中,也可設為不進行指紋認證而積極地輕鬆使用其他IDm。又,FeliCa Lite-S晶片的系統碼與使用於電子錢等的FeliCa Standard晶片不同,故內藏於智慧型手機8的非接觸式IC讀卡機9在因為電子錢的支付等,與外部機器進行NFC通訊時也不會發生妨礙。Furthermore, by simply using the non-contact IC card reader that holds the
在圖10、圖11揭示圖1所圖示的指紋認證系統中,啟動依據圖2所圖示的流程圖之iPhone用應用程式軟體時之對線圈5的供電狀態。圖10、圖11係第4例、第5例的時序圖。於第4例、第5例的時序圖中,與參照圖9的第3例的時序圖所說明的同樣地,將透過初期反應所辨識的其他NFC晶片追加至智慧型手機用的附指紋認證功能手機殼1內,對線圈5供電的話則稍微延遲而使其他NFC晶片成為動作狀態。在圖10的第4例的時序圖中,使其他NFC晶片成為2次動作狀態,在圖11的第5例的時序圖中,使其他NFC晶片到指紋認證成功為止都成為動作狀態。該等係因為相對於前述之圖9的第3例的時序,讓停止其他NFC晶片的時序延遲之故。10 and 11 illustrate the power supply state of the
在iPhone中,透過初期反應讓timeSlot值的變更成為有效而可進行連續供電,但是,從初期反應轉移至活動狀態之後,與NFC晶片的通訊停止的話,在一定時間後會解除連續供電。透過(i)如圖10的第4例的時序圖般,停止與NFC晶片的通訊後再次成為短時間動作狀態、(ii)如圖11的第5例的時序圖般,到指紋認證成功為止維持NFC晶片的通訊,增長連續供電的最長時間。此時,以配合所使用的智慧型手機,可變更使不同於IC晶片之其他NFC晶片從供電開始到成為動作狀態為止的延遲時間、動作時間、重複期間、重複次數等的參數之方式構成為佳。In the iPhone, the change in the timeSlot value is made effective through the initial response and continuous power supply can be provided. However, after the initial response is transferred to the active state, if the communication with the NFC chip stops, the continuous power supply will be terminated after a certain period of time. By (i) stopping the communication with the NFC chip and then returning to the short-term operating state as shown in the timing chart of the fourth example in Figure 10, (ii) until the fingerprint authentication is successful, as shown in the timing chart of the fifth example in Figure 11 Maintain communication with the NFC chip and increase the maximum time of continuous power supply. At this time, in accordance with the smartphone being used, the parameters such as the delay time, operation time, repetition period, and number of repetitions from the start of power supply to the activation state of the NFC chip different from the IC chip can be changed as follows good.
再者,如圖11的第5例的時序圖般,在到指紋認證成功為止維持NFC晶片的通訊時,依據圖2所圖示的流程圖之iPhone用軟體即使檢測出不同於IC晶片的其他NFC晶片的IDm,該軟體也會在步驟S7中以不結束之方式記憶其他NFC晶片的IDm。在讀入其他NFC晶片的IDm時,與IDm的讀取失敗時同樣地再次將開啟輪詢的指令發送至非接觸式IC讀卡機9,返回IDm資料的讀取步驟等,需要適當修正應用程式軟體。Furthermore, as shown in the timing chart of the fifth example in Figure 11, when communication with the NFC chip is maintained until fingerprint authentication is successful, even if the iPhone software based on the flow chart shown in Figure 2 detects an IC chip other than the The IDm of the NFC chip, the software will also memorize the IDm of other NFC chips in step S7 without ending. When reading the IDm of other NFC chips, the command to start polling is sent to the non-contact
在圖12揭示圖1所圖示的指紋認證系統中,啟動依據圖2所圖示的流程圖之iPhone用應用程式軟體時的供電狀態。圖12係第6例的時序圖。與圖9的第3例的時序圖同樣地,將透過初期反應所辨識的其他NFC晶片追加至智慧型手機用的附指紋認證功能手機殼1內,然後,對線圈5供電的話讓其他NFC晶片成為動作狀態,將此動作狀態維持到對線圈5之供電停止為止。FIG. 12 illustrates the power supply state of the fingerprint authentication system shown in FIG. 1 when the iPhone application software is started according to the flowchart shown in FIG. 2 . Figure 12 is a timing chart of the sixth example. Similar to the timing chart of the third example in Figure 9, other NFC chips identified through the initial response are added to the
參照圖12,指紋認證成功後,不僅FeliCa晶片6,其他NFC晶片也同時維持動作狀態。於該其他NFC晶片之種類的選擇中,需要選擇即使在進行了初期反應之其他NFC晶片動作的狀態下,也可讀取未進行初期反應之FeliCa晶片6的IDm之NFC晶片的種類。Referring to Figure 12, after the fingerprint authentication is successful, not only the
如前述般,FeliCa係初期反應時1個FeliCa晶片反應的話,可讀取複數FeliCa晶片。對於為了讀取複數FeliCa晶片來說,透過指定IDm或指定系統碼,相符的FeliCa晶片會反應。然而,在CoreNFC中並無指定IDm的方法。因此,需要指定系統碼,讀取對應的FeliCa晶片。此時,指定複數系統碼的話,也可同時讀取對應各自的FeliCa晶片。As mentioned above, if one FeliCa wafer reacts during the initial reaction of the FeliCa system, multiple FeliCa wafers can be read. For reading multiple FeliCa chips, by specifying IDm or specifying system code, the matching FeliCa chip will respond. However, there is no way to specify IDm in CoreNFC. Therefore, it is necessary to specify the system code and read the corresponding FeliCa chip. At this time, if multiple system codes are specified, the corresponding FeliCa chips can be read simultaneously.
在相同系統碼的FeliCa晶片有複數個時,無法同時讀取複數個,故其他NFC晶片設為與FeliCa晶片6的系統碼不同的FeliCa晶片即可。在此,於iPhone中,為了不因為電子錢的支付等而妨礙到與特定系統碼之FeliCa晶片的通訊,作為其他NFC晶片選擇與該等系統碼不同之系統碼的FeliCa晶片為佳。When there are multiple FeliCa chips with the same system code, multiple NFC chips cannot be read at the same time, so the other NFC chips can be set to FeliCa chips with different system codes from the
如圖12的第6例的時序圖般,組入系統碼不同的2個FeliCa晶片,然後,一方的FeliCa晶片無關於指紋認證而對線圈5的供電期間中持續動作狀態的狀況中,不需要與指紋認證部3對合時序。因此,考量於圖1所圖示的指紋認證系統中,在手機殼1內將FeliCa卡或具有同等功能的卡片貼或者可撓性基板模組等,不與手機殼1內的指紋認證功能電路基板11有線連接而直接組入至手機殼1內的方法。當然,透過在安裝指紋認證部3及FeliCa晶片6的指紋認證功能電路基板11,安裝系統碼不同的FeliCa晶片,共有線圈5以降低成本亦可。然而,可使用2個系統碼相同的FeliCa晶片之圖9、圖10及圖11所圖示的時序圖的實施例可更進一步降低成本,FeliCa晶片的動作時間短,故消費電力也變少。As shown in the timing chart of the sixth example in Figure 12, two FeliCa chips with different system codes are assembled, and then, in a situation where one FeliCa chip continues to operate while powering the
如以上所述般,依據基於圖8、圖9、圖10、圖11及圖12所圖示的時序圖說明的實施例,僅利用本來的應用程式軟體,即使是無法讓來自內藏於智慧型手機8之非接觸式IC讀卡機9的供電成為連續狀態之iPhone等的智慧型手機,也可透過(i)將指紋認證功能搭載於手機殼1,(ii)接受來自內藏於智慧型手機8之非接觸式IC讀卡機9的供電而開始指紋認證,(iii)藉由透過初期反應辨識NFC晶片而使供電成為連續狀態,(iv)在指紋認證成功時非接觸式IC讀卡機接收指紋認證通知,將「被認證為相同的指紋」一事傳達給智慧型手機8。因此,可不用與智慧型手機有線連接而對於智慧型手機8實質追加指紋認證功能。As mentioned above, according to the embodiment described based on the timing diagrams shown in FIGS. 8, 9, 10, 11, and 12, only using the original application software, even if it is impossible to use the built-in smart Smartphones such as the iPhone where the power supply to the contactless
又,在透過初期反應所辨識出的NFC晶片是FeliCa晶片時,藉由適切選擇系統碼,於(i)啟動本應用程式軟體以外的應用程式軟體,透過非接觸式IC讀卡機9讀取NFC卡的狀況、(ii)內藏於智慧型手機的非接觸式IC讀卡機9因為電子錢的支付等而與外部機器進行NFC通訊的狀況等中,本發明的實施例可實現不發生妨礙。In addition, when the NFC chip identified through the initial response is a FeliCa chip, by appropriately selecting the system code, (i) start the application software other than this application software and read it through the contactless
於圖8、圖9、圖10、圖11及圖12中,僅利用本來應用程式軟體,透過對於無法讓來自內藏的非接觸式IC讀卡機的供電成為連續狀態之iPhone等的智慧型手機,利用初期反應辨識出NFC晶片,可利用應用程式軟體來實現連續供電。因此,不僅智慧型手機用的附指紋認證功能手機殼1,也可讓不進行連續供電的話就不會動作之其他非接觸式IC卡動作。利用獨立的電路基板來實現利用該初期反應辨識NFC晶片的功能,將該電路基板組入至參照圖5所說明之手機殼1的外殼10內亦可,也可藉由緊貼在內藏於智慧型手機8的非接觸式IC讀卡機9的附近,讓不進行連續供電的話就不會動作之附指紋認證功能的非接觸式IC卡動作,來使用其指紋認證功能。In Figures 8, 9, 10, 11, and 12, only the original application software is used to control smart devices such as iPhones that cannot provide continuous power supply from the built-in contactless IC card reader. The mobile phone uses the initial response to identify the NFC chip and can use the application software to achieve continuous power supply. Therefore, not only the
圖13係揭示關聯於本發明之指紋認證系統的區塊圖,透過獨立的電路基板,執行透過初期反應以辨識NFC晶片的功能。於圖13中,對於與圖1所圖示相同要素附加相同的參照符號。圖13所圖示的參照符號13為透過初期反應所辨識的NFC晶片。參照符號14為不同於上述之線圈5的其他第2線圈。參照符號15為輔助電路基板。參照符號16為附指紋認證功能的非接觸式IC卡或指紋認證功能電路基板。為了與第2線圈14區別,將參照符號5的線圈稱為「第1線圈」。Figure 13 shows a block diagram of the fingerprint authentication system related to the present invention, which implements the function of identifying the NFC chip through an initial reaction through an independent circuit substrate. In FIG. 13 , the same elements as those shown in FIG. 1 are assigned the same reference numerals.
參照圖13,在本發明的實施例中,圖示的指紋認證系統中,搭載於附指紋認證功能的非接觸式IC卡或指紋認證功能電路基板16的裝置,亦即指紋感測器2、指紋認證部3、保存對照用指紋資料的記憶體4、第1線圈5、IC晶片(FeliCa晶片6)構成指紋認證手段Fp。該指紋認證手段Fp進行與圖1的智慧型手機用的附指紋認證功能手機殼1內的指紋認證手段Fp相同動作。另一方面,於輔助電路基板15搭載NFC晶片13、第2線圈14,從讀卡機9對於第2線圈14進行供電的話,接受供電的第2線圈14係對NFC晶片13供給電力,NFC晶片13進行與讀卡機9的通訊,藉由初期反應被辨識。在此階段中智慧型手機8如iPhone般即使是僅利用應用程式軟體的話無法讓來自內藏之非接觸式IC讀卡機的供電成為連續狀態的機種,來自讀卡機9的供電也可成為連續狀態。對於第1線圈5進行連續供電的話,接受供電的第1線圈5對指紋感測器2、指紋認證部3、記憶體4等供給電力,然後開始指紋認證,可透過智慧型手機8使用指紋認證功能。Referring to Figure 13, in the embodiment of the present invention, in the fingerprint authentication system shown in the figure, a device mounted on a non-contact IC card with a fingerprint authentication function or a fingerprint authentication
搭載於輔助電路基板15的NFC晶片13係在搭載於附指紋認證功能的非接觸式IC卡或指紋認證功能電路基板的IC晶片是FeliCa晶片時,藉由使用系統碼不同的FeliCa晶片,如圖12的時序圖般,以藉由第2線圈14的供電而NFC晶片時常動作之方式構成亦可,如圖9的時序圖般,以對輔助電路基板15追加控制NFC晶片13的啟動時序的電路,從第2線圈14的供電開始僅短時間中讓NFC晶片動作的方式構成亦可。The
圖14、圖15係用以說明智慧型手機8與第2線圈14的相對位置的剖面圖。於圖14、圖15中,對於與圖13所圖示相同要素附加相同的參照符號。本案發明者係以美國Apple公司的iPhone,透過作為輔助電路基板15市面上販賣之FeliCa卡及具有同等功能的卡片貼或可撓性基板模組確認動作。該等FeliCa卡等係如圖12的時序圖般,藉由第2線圈14的供電而NFC晶片13時常動作者,除了線圈的大小以外,並無太大差異。在將該等FeliCa卡等,作為輔助電路基板15,在幾台iPhone上,如圖14般以收於iPhone的底面之方式置放時,輔助電路基板15並不動作,如圖15般僅輔助電路基板15從iPhone的底面大幅超出時動作。14 and 15 are cross-sectional views for explaining the relative positions of the
於iPhone中,輔助電路基板15不是如圖15般從iPhone的底面大幅超出的狀態的話,輔助電路基板15不動作的理由係從內藏於iPhone的非接觸式IC讀卡機9產生的交變磁場主要從iPhone的側面發出,如未以該交變磁場的磁通通過第2線圈14中之方式配置輔助電路基板15的話,則無法供給讓NFC晶片13動作之充分的電力之故。所以,在輔助電路基板15的形狀為平板時,如圖15般,會從iPhone的底面大幅超出。In the iPhone, if the
圖16係用以說明對於智慧型手機8之第2線圈14的配置的圖。於圖16中,對於與圖13所圖示相同要素附加相同的參照符號。於圖16中,輔助電路基板15係藉由將基板的一部分或全部設為可撓性印刷基板等,以彎曲輔助電路基板15的一部分而覆蓋智慧型手機8的底面與側面的一部分之方式構成。藉此,可讓從非接觸式IC讀卡機9產生之交變磁場的磁通通過第2線圈14中。又,輔助電路基板15並不會從智慧型手機8大幅超出。將市面上販賣的FeliCa卡以內部的配線不會斷線之方式彎曲,並將其作為輔助電路基板15,如圖16所圖示般安裝於iPhone的時候,確認透過來自內藏於iPhone的非接觸式IC讀卡機9的供電,FeliCa卡(輔助電路基板15)內的FeliCa晶片(NFC晶片13)啟動,透過初期反應而FeliCa晶片被非接觸式IC讀卡機9辨識,成為連續供電狀態。FIG. 16 is a diagram illustrating the arrangement of the
圖17、圖18係用以說明圖13之指紋認證系統的剖面圖。於圖17、圖18中,對於與圖13所圖示相同要素附加相同的參照符號。圖17、圖18所圖示的參照符號17為安裝於智慧型手機8的智慧型手機用手機殼。參照符號18為附指紋認證功能的非接觸式IC卡,圖13的附指紋認證功能的非接觸式IC卡或指紋認證功能電路基板16的形狀成形為***尺寸。參照符號19為LED,構成安裝於附指紋認證功能的非接觸式IC卡18,顯示附指紋認證功能的非接觸式IC卡的供電狀況及指紋認證的成功、失敗等的顯示部。Figures 17 and 18 are cross-sectional views illustrating the fingerprint authentication system of Figure 13. In FIGS. 17 and 18 , the same elements as those shown in FIG. 13 are assigned the same reference numerals.
於圖17、圖18中,輔助電路基板15係如圖16所示,藉由將基板的一部分或全部設為可撓性印刷基板等,而彎曲一部分。藉由該彎曲的部分,以輔助電路基板15覆蓋智慧型手機8的底面與側面的一部分。從非接觸式IC讀卡機9產生之交變磁場的磁通會通過第2線圈14中。藉此,可透過來自非接觸式IC讀卡機9的無線供電而讓輔助電路基板15動作。輔助電路基板15透過雙面膠帶等固定於智慧型手機用手機殼17。輔助電路基板15係直接透過雙面膠帶等固定於智慧型手機8亦可,但考慮修理等的維護,以可從智慧型手機8容易裝卸之方式固定為佳。又,藉由從智慧型手機8使輔助電路基板15隔開手機殼的厚度份量,可擴大通過來自非接觸式IC讀卡機9的交變磁場之第2線圈14的有效面積。藉此,輔助電路基板15可接受更穩定的供電。In FIGS. 17 and 18 , as shown in FIG. 16 , the
參照圖17,圖17圖示在透過智慧型手機用手機殼17,將輔助電路基板15安裝於智慧型手機8的狀態下,讓附指紋認證功能的非接觸式IC卡18在非接觸式IC讀卡機9附近被存取的狀態。在此狀態下開始來自非接觸式IC讀卡機9的供電的話,輔助電路基板15內的NFC晶片13會啟動,透過初期反應而NFC晶片13被非接觸式IC讀卡機9辨識,然後,對於附指紋認證功能的非接觸式IC卡18成為連續供電狀態而變成可進行指紋認證。於圖17中,彎曲作為輔助電路基板15而大小不同之FeliCa卡及具有同等功能的卡片貼或可撓性基板模組的一部分來確認動作。覆蓋智慧型手機8的底面之第2線圈14的面積大的話可對附指紋認證功能的非接觸式IC卡18供給可動作之充分的電力,結果,可確認到非接觸式IC讀卡機9與附指紋認證功能的非接觸式IC卡18的相對位置的範圍擴大。此係由於透過第2線圈14,可將來自非接觸式IC讀卡機9的電力更廣範圍地供電。Referring to FIG. 17, FIG. 17 illustrates a state in which the
參照圖18,在圖示的實施例中,於智慧型手機用手機殼17追加保持卡的機構。藉由將該卡保持機構追加至手機殼17,不使用附指紋認證功能的非接觸式IC卡18時可將附指紋認證功能的非接觸式IC卡18收納於智慧型手機用手機殼17。在進行指紋認證時,從智慧型手機用手機殼17拉出附指紋認證功能的非接觸式IC卡18,在如圖18的狀態下進行指紋認證。圖17、圖18任一狀況中指紋感測器2都在智慧型手機8的畫面側,故可藉由一邊實際以眼確認指紋感測器2的位置及指紋感測器2一邊透過手指7觸碰指紋感測器2,確實地進行指紋認證。又,藉由附指紋認證功能的非接觸式IC卡18上的LED19,可一邊確認供電狀況及指紋認證的成功、失敗等,一邊進行指紋認證。像圖18的使用方法也可在圖17的手機殼17貼上市面販售之保持***尺寸之卡片的卡片收納夾來使用。Referring to FIG. 18 , in the illustrated embodiment, a card holding mechanism is added to the
於圖17、圖18中,藉由區分使用複數附指紋認證功能的非接觸式IC卡18,可區別法人用與個人用進行各別的卡的指紋認證,可實現更高的安全防護。又,變成可透過1張附指紋認證功能的非接觸式IC卡18,不僅智慧型手機8,也可實現在其他終端之指紋認證功能的使用,提升便利性。In Figures 17 and 18, by distinguishing and using a plurality of
依據圖13、圖17、圖18所圖示的指紋認證系統,可提供與內藏於智慧型手機的指紋認證裝置同等的使用便利性。不僅如此,像SIM卡交換攻擊般,對於罪犯對於轉移了電話號碼之新的智慧型手機,罪犯藉由登記本身的生物資訊,讓智慧型手機內藏的臉部認證及指紋認證無效化的攻擊,也可以確保安全防護。亦即,僅透過SIM卡交換攻擊的話,罪犯並無法取得已登記指紋之附指紋認證功能的非接觸式IC卡18。即使取得指紋未登記之新的附指紋認證功能的非接觸式IC卡18,罪犯登記本身的指紋,也因為固有的資料不同,即使受到SIM卡交換攻擊,也不會辨識出指紋認證已成功。即使罪犯取得已登記指紋之附指紋認證功能的非接觸式IC卡18,利用罪犯的指紋,指紋認證也不會成功。如此,本發明的指紋認證系統可說是對於SIM卡交換攻擊也有效的認證裝置。依據本發明的指紋認證系統,可提供比內藏於智慧型手機的指紋認證裝置更高的安全防護。The fingerprint authentication system shown in Figures 13, 17, and 18 can provide the same usability as a fingerprint authentication device built into a smartphone. Not only that, like the SIM card swap attack, criminals register their own biometric information on a new smartphone that has transferred their phone number, thereby invalidating the face authentication and fingerprint authentication built into the smartphone. , which can also ensure safety protection. That is to say, if only through SIM card swapping attacks, criminals cannot obtain the
又,圖13、圖17、圖18所圖示的輔助電路基板15係如iPhone般即使是僅利用應用程式軟體的話無法讓來自內藏之非接觸式IC讀卡機的供電成為連續狀態的機種,也能以可實現供電成為連續狀態之方式安裝於智慧型手機。此外,如果是安裝狀態的話,從智慧型手機任何時候都可以對輔助電路基板15的NFC晶片13進行存取,確認IDm等的固有號碼等,故可作為多重要素認證之一來使用。輔助電路基板15所致之認證並不是指紋認證,故在輔助電路基板15失竊時,對於SIM卡交換攻擊無效。但是,在輔助電路基板15為失竊時,成為對於SIM卡交換攻擊也有效的認證裝置。因為不需要碰觸指紋感測器等的作業,透過網路銀行進行高額度的匯款等設為需要附指紋認證功能的非接觸式IC卡18所致之認證,在網路銀行之登入及照會餘額中可使用輔助電路基板15的認證而進行順暢的運用。In addition, the
輔助電路基板15如上所述般並不是指紋認證,故在輔助電路基板15失竊時,對於SIM卡交換攻擊無效。然而,透過1張電路基板構成輔助電路基板15與指紋認證功能電路基板,如圖3及圖4的指紋認證功能電路基板11般構成,藉此即使在失竊的狀況中也可阻擋SIM卡交換攻擊。再者,設為1張電路基板之際,設計以1個線圈兼用於第1線圈與第2線圈的電路基板對於該發明所屬技術領域中具有通常知識者來說是容易的設計事項。As mentioned above, the
