圖1為根據本揭露一實施例的影像簽章系統的方塊圖。FIG. 1 is a block diagram of an image signature system according to an embodiment of the present disclosure.

請參照圖1，根據本揭露一實施例的影像簽章系統100包括伺服器110及耦接到伺服器110的電子裝置120。伺服器110例如是數位簽章驗證伺服器且電子裝置120例如是智慧型手機、平板電腦或其他類似裝置。相機模組121可包括前鏡頭模組及後鏡頭模組的至少其中之一。處理模組122例如是中央處理器(Central Processing Unit，CPU)或其他類似元件。感應模組123例如包括近場通訊(NFC)晶片。Referring to FIG. 1 , an image signature system 100 according to an embodiment of the present disclosure includes a server 110 and an electronic device 120 coupled to the server 110 . The server 110 is, for example, a digital signature verification server and the electronic device 120 is, for example, a smart phone, a tablet computer, or other similar devices. The camera module 121 may include at least one of a front lens module and a rear lens module. The processing module 122 is, for example, a central processing unit (Central Processing Unit, CPU) or other similar components. The sensing module 123 includes, for example, a near field communication (NFC) chip.

在一實施例中，使用者可利用電子裝置120的相機模組121拍攝使用者(例如，進行自拍)以產生第一影像，並利用相機模組121拍攝使用者所持有的晶片卡(例如，IC晶片卡)上的使用者照片以產生第二影像。接著，使用者可利用感應模組123讀取晶片卡內的圖檔資料(例如，使用者照片的圖檔資料)以取得第三影像。In one embodiment, the user can use the camera module 121 of the electronic device 120 to photograph the user (eg, take a selfie) to generate a first image, and use the camera module 121 to photograph the chip card held by the user (eg, take a selfie) , IC chip card) on the user's photo to generate the second image. Then, the user can use the sensing module 123 to read the graphic data in the chip card (eg, graphic data of the user's photo) to obtain the third image.

接著，電子裝置120根據文件產生檔案，此檔案可為文件字串、文件檔案或文件影像並用於開戶申請、轉帳等交易請求。舉例來說，此檔案可為金融業務申請檔案(例如，開戶申請檔案、金融卡申請檔案、***申請檔案、貸款申請檔案等)、金融交易申請檔案(例如，提款交易檔案、轉帳交易檔案、匯款交易檔案、繳費交易檔案、繳稅交易檔案、投資交易檔案等)、金融申請文件影像(例如，開戶申請文件影像、金融卡申請文件影像、***申請文件影像、貸款申請文件影像等)、金融交易文件影像(例如，提款交易文件影像、轉帳交易文件影像、匯款交易文件影像、繳費交易文件影像、繳稅交易文件影像、投資交易文件影像等)、金融申請文件字串(例如，開戶申請文件字串、金融卡申請文件字串、***申請文件字串、貸款申請文件字串等)或金融交易文件字串(例如，提款交易文件字串、轉帳交易文件字串、匯款交易文件字串、繳費交易文件字串、繳稅交易文件字串、投資交易文件字串等)。處理模組122將第一影像、第二影像、第三影像的至少任二影像及檔案進行不可逆運算(例如，雜湊演算法)產生簽章檔，並將第一影像、第二影像、第三影像的至少任二影像及檔案及簽章檔傳送到伺服器110。雜湊演算法可搭配個人化參數或隨機變數或不搭配任何資料進行運算。伺服器110將第一影像、第二影像、第三影像的至少任二影像及檔案進行不可逆運算產生比對簽章檔。當簽章檔與比對簽章檔內容相同且第一影像、第二影像、第三影像的至少任二影像的特徵相符，則伺服器110產生簽章確認訊息並執行對應檔案的請求。舉例來說，伺服器110可預先接收使用者透過應用程式傳送的交易請求並在簽章確認訊息產生後直接執行此交易請求，或可根據檔案名稱確認檔案對應的交易請求並執行此交易請求。在一實施例中，第一影像、第二影像、第三影像的至少任二影像及檔案可藉由一應用程式來獲得。Next, the electronic device 120 generates a file according to the file, and the file can be a file string, a file file or a file image and is used for transaction requests such as account opening application and fund transfer. For example, this file can be a financial business application file (eg, an account opening application file, a financial card application file, a credit card application file, a loan application file, etc.), a financial transaction application file (eg, a withdrawal transaction file, a transfer transaction file, remittance transaction files, bill payment transaction files, tax payment transaction files, investment transaction files, etc.), financial application documents images (for example, account opening application documents images, financial card application documents images, credit card application documents images, loan application documents images, etc.), financial Transaction document images (eg, withdrawal transaction document images, transfer transaction document images, remittance transaction document images, bill payment transaction document images, tax payment transaction document images, investment transaction document images, etc.), financial application document strings (eg, account opening application file string, financial card application file string, credit card application file string, loan application file string, etc.) or financial transaction file string (for example, withdrawal transaction file string, transfer transaction file string, remittance transaction file string string, payment transaction file string, tax payment transaction file string, investment transaction file string, etc.). The processing module 122 performs an irreversible operation (eg, a hash algorithm) on at least any two images and files of the first image, the second image, and the third image to generate a signature file, and converts the first image, the second image, the third image, and the third image into a signature file. At least any two of the images and the file and signature file are sent to the server 110 . The hash algorithm can be operated with personalized parameters or random variables or without any data. The server 110 performs an irreversible operation on at least any two images and files of the first image, the second image, and the third image to generate a comparison signature file. When the signature file and the comparison signature file have the same content and the features of at least any two images of the first image, the second image, and the third image match, the server 110 generates a signature confirmation message and executes the request for the corresponding file. For example, the server 110 may receive the transaction request sent by the user through the application in advance and directly execute the transaction request after the signature confirmation message is generated, or may confirm the transaction request corresponding to the file according to the file name and execute the transaction request. In one embodiment, at least any two images and files of the first image, the second image, and the third image can be obtained by an application program.

舉例來說，當簽章檔由第一影像及第二影像及檔案透過不可逆運算產生時，則伺服器100將第一影像及第二影像及檔案進行不可逆運算產生比對簽章檔並當簽章檔與比對簽章檔內容相同且第一影像及第二影像的特徵相符時產生簽章確認訊息並執行對應檔案的請求。類似地，當簽章檔由第一影像及第三影像及檔案透過不可逆運算產生時，則伺服器100將第一影像及第三影像及檔案進行不可逆運算產生比對簽章檔並當簽章檔與比對簽章檔內容相同且第一影像及第三影像的特徵相符時產生簽章確認訊息並執行對應檔案的請求。類似地，當簽章檔由第二影像及第三影像及檔案透過不可逆運算產生時，則伺服器100將第二影像及第三影像及檔案進行不可逆運算產生比對簽章檔並當簽章檔與比對簽章檔內容相同且第二影像及第三影像的特徵相符時產生簽章確認訊息並執行對應檔案的請求。類似地，當簽章檔由第一影像、第二影像及第三影像及檔案透過不可逆運算產生時，則伺服器100將第一影像、第二影像及第三影像及檔案進行不可逆運算產生比對簽章檔並當簽章檔與比對簽章檔內容相同且第一影像、第二影像及第三影像的特徵相符時產生簽章確認訊息並執行對應檔案的請求。For example, when the signature file is generated from the first image, the second image and the file through irreversible operations, the server 100 performs irreversible operations on the first image, the second image and the file to generate a comparison signature file which is then signed. When the content of the signature file is the same as that of the comparison signature file and the features of the first image and the second image match, a signature confirmation message is generated and a request for the corresponding file is executed. Similarly, when the signature file is generated from the first image, the third image and the file through irreversible operations, the server 100 performs irreversible operations on the first image and the third image and the file to generate a comparison signature file and use it as a signature When the content of the file is the same as that of the comparison signature file and the features of the first image and the third image are consistent, a signature confirmation message is generated and a request for the corresponding file is executed. Similarly, when the signature file is generated from the second image, the third image and the file through irreversible operations, the server 100 performs the irreversible operation on the second image, the third image and the file to generate a comparison signature file and use it as a signature When the content of the file is the same as that of the comparison signature file and the features of the second image and the third image match, a signature confirmation message is generated and a request for the corresponding file is executed. Similarly, when the signature file is generated from the first image, the second image, the third image and the file through an irreversible operation, the server 100 performs an irreversible operation on the first image, the second image and the third image and the file to generate a ratio. For the signature file and when the content of the signature file and the comparison signature file are the same and the features of the first image, the second image and the third image match, a signature confirmation message is generated and a request for the corresponding file is executed.

值得注意的是，處理模組122還可壓縮簽章檔以產生一個壓縮簽章檔並設定一個預定解壓縮密碼，且伺服器110在收到壓縮簽章檔時會先利用預定解壓縮密碼對壓縮簽章檔進行解壓縮操作以得到簽章檔，再進行後續的簽章檔與比對簽章檔的比對。It is worth noting that the processing module 122 can also compress the signature file to generate a compressed signature file and set a predetermined decompression password, and the server 110 will first use the predetermined decompression password when receiving the compressed signature file. The compressed signature file is decompressed to obtain the signature file, and then the subsequent signature file is compared with the comparison signature file.

在一實施例中，晶片卡內的圖檔資料的取得可透過使用者手動輸入資料來完成。具體來說，電子裝置120可接收使用者的預設字串輸入，例如提示使用者輸入自己的護照號碼，並藉由感應模組123根據預設字串輸入來讀取晶片卡內的晶片卡資料，其中晶片卡資料包括圖檔資料。晶片卡資料除了使用者照片的圖檔資料之外還可包括例如身分證字號等使用者個資。在另一實施例中，使用者可利用相機模組121拍攝晶片卡上的條碼(例如，護照條碼)以產生條碼影像。在電子裝置120獲得包含條碼的條碼影像之後，處理模組122可解碼條碼影像中的條碼以獲得使用者識別碼資料(例如，護照號碼資料)，並藉由感應模組123可根據識別碼資料來讀取晶片卡內的圖檔資料(例如，使用者照片的圖檔資料)以取得第三影像。In one embodiment, the acquisition of the graphic data in the chip card can be accomplished by the user manually inputting the data. Specifically, the electronic device 120 can receive the user's preset string input, such as prompting the user to input his own passport number, and the sensor module 123 can read the chip card in the chip card according to the preset string input. data, wherein the chip card data includes graphic data. The chip card data can also include user personal information such as the ID card number in addition to the image file data of the user's photo. In another embodiment, the user can use the camera module 121 to capture a barcode (eg, a passport barcode) on the chip card to generate a barcode image. After the electronic device 120 obtains the barcode image including the barcode, the processing module 122 can decode the barcode in the barcode image to obtain user identification code data (eg, passport number data), and the sensing module 123 can use the sensing module 123 to obtain the user identification code data according to the identification code data. to read the graphic data in the chip card (for example, graphic data of the user's photo) to obtain the third image.

在一實施例中，影像特徵辨識可透過判斷各個影像中的臉部特徵是否相符來進行。具體來說，伺服器110可分析第一影像、第二影像及第三影像中對應眼、耳、鼻、口、痣、瘤的至少其中之一的幾何特徵的特徵相似度，若其中兩個影像的特徵相似度大於門檻值則這兩個影像的特徵相符。幾何特徵包括對應眼、耳、鼻、口、痣、瘤的至少其中之一的距離、面積或角度。舉例來說，臉部特徵可包括兩眼距離、嘴巴寬度、嘴巴與鼻子構成的三角型面積、嘴巴與鼻子構成的三角型的底角角度等特徵。在一範例中，若第一影像、第二影像及第三影像的嘴巴寬度的誤差值在一定範圍之內，則判斷第一影像、第二影像及第三影像的特徵相似度大於門檻值。在一實施例中，若第一影像及第三影像的特徵相似度大於第一門檻值則第一影像及第三影像的特徵相符。若第二影像及第三影像的特徵相似度大於第二門檻值則第二影像及第三影像的特徵相符。由於第二影像與第三影像的差異理論上會比第一影像與第三影像的差異小，因此第二門檻值可設定為大於第一門檻值，例如第二門檻值為95%且第一門檻值為80%。In one embodiment, the image feature recognition may be performed by determining whether the facial features in each image match. Specifically, the server 110 may analyze the feature similarity of the geometric features corresponding to at least one of the eyes, ears, nose, mouth, moles, and tumors in the first image, the second image, and the third image. If the feature similarity of the images is greater than the threshold value, the features of the two images match. The geometric features include distances, areas or angles corresponding to at least one of eyes, ears, nose, mouth, moles, and tumors. For example, the facial features may include the distance between the eyes, the width of the mouth, the area of the triangle formed by the mouth and the nose, and the angle of the base angle of the triangle formed by the mouth and the nose. In an example, if the error value of the mouth width of the first image, the second image and the third image is within a certain range, it is determined that the feature similarity of the first image, the second image and the third image is greater than the threshold value. In one embodiment, if the feature similarity of the first image and the third image is greater than the first threshold value, the features of the first image and the third image match. If the feature similarity between the second image and the third image is greater than the second threshold, the features of the second image and the third image match. Since the difference between the second image and the third image is theoretically smaller than the difference between the first image and the third image, the second threshold can be set to be greater than the first threshold, for example, the second threshold is 95% and the first The threshold value is 80%.

本揭露一實施例的影像簽章方法包括：拍攝使用者以產生第一影像；拍攝晶片卡上的使用者照片以產生第二影像；讀取晶片卡內的圖檔資料以取得第三影像；獲得檔案；將第一影像、第二影像、第三影像的至少任二影像及檔案進行不可逆運算產生簽章檔，並將至少任二影像及檔案及簽章檔傳送到伺服器；藉由伺服器將至少任二影像及檔案進行不可逆運算產生比對簽章檔；以及當簽章檔與比對簽章檔內容相同且至少任二影像的特徵相符，則藉由伺服器產生簽章確認訊息並執行對應檔案的請求。An image signature method of an embodiment of the present disclosure includes: photographing a user to generate a first image; photographing a photo of the user on a chip card to generate a second image; reading image data in the chip card to obtain a third image; Obtain files; perform irreversible operations on at least any two images and files of the first image, the second image and the third image to generate a signature file, and transmit at least any two images, files and signature files to the server; The server performs irreversible operations on at least any two images and files to generate a comparison signature file; and when the content of the signature file and the comparison signature file is the same and the characteristics of at least any two images match, the server generates a signature confirmation message And execute the request for the corresponding file.
