Description

智慧家庭保全系統及保全設定的解除方法Smart home security system and how to cancel security settings

本發明係有關一種保全系統，特別是關於一種保全設定的解除方法。The present invention relates to a security system, in particular to a method for releasing security settings.

智慧家庭網路(smart home network)是電腦網路的一種，藉由(無線或有線)通信以連接家裡的各種電子裝置，使其互動而增進或創造更多功能。在一應用例子中，智慧家庭網路可建構智慧家庭保全系統，當使用者離開家時，藉由閘道器將保全設定(security setting)進行設定(arm)；當回到家時，再將保全設定予以解除(disarm)。在設定與解除的這段期間，如果有任何保全裝置被觸發，則可藉由信息(message)、電子郵件或電話以通知在外的使用者。A smart home network is a type of computer network that uses (wireless or wired) communication to connect various electronic devices in the home to interact with each other to enhance or create more functions. In an application example, a smart home network can construct a smart home security system. When the user leaves home, the security setting is set (arm) through the gateway; when the user returns home, the security setting is set (arm). The setting is disarmed. During the period of setting and disabling, if any security device is triggered, the users outside can be notified by message, email or phone.

於傳統保全系統，使用者藉由輸入密碼以解除保全設定。然而，密碼容易被他人竊取或破解。甚者，當保全設定被他人非法解除後，更無法得知究竟是誰進行解除的。In traditional security systems, users can unlock security settings by entering a password. However, the password is easily stolen or cracked by others. What's more, when the security setting is illegally cancelled by others, it is even harder to know who has cancelled it.

因此亟需提出一種新穎的保全機制，用以克服傳統保全系統的缺失。Therefore, it is urgent to propose a novel security mechanism to overcome the shortcomings of the traditional security system.

鑑於上述，本發明實施例的目的之一在於提出一種智慧家庭保全設定的解除方法，除使用密碼識別外，更增加臉部偵測，藉此不但可增進安全性，且能得知入侵者的容貌。In view of the foregoing, one of the objectives of the embodiments of the present invention is to provide a method for releasing the security settings of a smart home, which not only uses password recognition but also increases face detection, thereby not only improving security, but also knowing the intruder’s appearance.

根據本發明實施例之智慧家庭保全設定的解除方法，顯示提示頁面，指示使用者進行臉部的影像擷取，且擷取至少一張使用者的臉部影像。當臉部影像當中臉部面積占整個臉部的比例大於預設第一臨界值且臉部影像的影像品質大於預設第二臨界值，則允許使用者輸入密碼。若密碼未識別成功，則發送警告通知。According to the method for releasing the security setting of the smart home according to the embodiment of the present invention, a prompt page is displayed to instruct the user to perform facial image capture, and to capture at least one facial image of the user. When the ratio of the face area to the entire face in the facial image is greater than the preset first threshold and the image quality of the facial image is greater than the preset second threshold, the user is allowed to enter the password. If the password is not successfully recognized, a warning notification will be sent.

第一圖顯示本發明實施例之智慧家庭保全(smart home security)系統100的方塊圖。在本實施例中，智慧家庭保全系統(以下簡稱保全系統)100主要包含閘道器11、影像擷取裝置12、輸出入裝置13及記憶裝置14。在本實施例中，閘道器11係作為智慧家庭網路當中的伺服器，用以控制影像擷取裝置12、輸出入裝置13及記憶裝置14。此外，閘道器11至少包含影像處理器111，用以執行影像處理。在一實施例中，影像擷取裝置12可包含相機；輸出入裝置13可包含觸控螢幕；且記憶裝置14可包含記憶體，用以儲存資料庫141與暫存資料。其中，影像擷取裝置12可設於輸出入裝置13內。The first figure shows a block diagram of a smart home security system 100 according to an embodiment of the present invention. In this embodiment, the smart home security system (hereinafter referred to as the security system) 100 mainly includes a gateway 11, an image capture device 12, an input/output device 13, and a memory device 14. In this embodiment, the gateway 11 is used as a server in the smart home network to control the image capturing device 12, the I/O device 13, and the memory device 14. In addition, the gateway 11 at least includes an image processor 111 for performing image processing. In one embodiment, the image capturing device 12 may include a camera; the I/O device 13 may include a touch screen; and the memory device 14 may include a memory for storing the database 141 and temporary data. Among them, the image capturing device 12 can be provided in the input/output device 13.

第二圖顯示本發明實施例之智慧家庭保全設定的解除方法200之流程圖，可適用於智慧家庭網路，如第一圖所示保全系統100。於步驟21，閘道器11檢視是否收到解除要求。在一實施例中，當使用者欲進行保全設定的解除時，需啟動輸出入裝置13，例如觸碰輸出入裝置13的觸控螢幕。當輸出入裝置13收到解除要求時，會發出信號以通知閘道器11。此時，閘道器11會控制輸出入裝置13以顯示提示頁面(步驟22)，指示使用者面向影像擷取裝置12(或者面向輸出入裝置13)以進行臉部影像的擷取。第三A圖例示輸出入裝置13的提示頁面31。在本實施例中，提示頁面31包含即時影像區311，用以顯示影像擷取裝置12所擷取的目前影像。提示頁面31還包含密碼輸入區312，用以讓使用者輸入預設密碼以進行識別(identification)。The second figure shows a flowchart of the method 200 for releasing the security settings of a smart home according to an embodiment of the present invention, which can be applied to a smart home network, such as the security system 100 shown in the first figure. In step 21, the gateway 11 checks whether it receives a cancellation request. In one embodiment, when the user wants to cancel the security setting, the I/O device 13 needs to be activated, for example, by touching the touch screen of the I/O device 13. When the I/O device 13 receives the cancellation request, it will send a signal to notify the gateway 11. At this time, the gateway 11 controls the I/O device 13 to display a prompt page (step 22), instructing the user to face the image capture device 12 (or face the I/O device 13) to capture facial images. The third diagram A illustrates the prompt page 31 of the input/output device 13. In this embodiment, the prompt page 31 includes a real-time image area 311 for displaying the current image captured by the image capturing device 12. The prompt page 31 also includes a password input area 312 for the user to input a preset password for identification.

於步驟23，閘道器11控制影像擷取裝置12以擷取至少一張使用者的臉部影像。如果未擷取到涵蓋完整臉部的清晰(clear)影像，則影像擷取裝置12會持續進行影像擷取，直到預設第一期間(例如30秒)已到達。在本說明書中，“完整”係指絕大部分(例如90%)的臉部位於影像擷取裝置12的鏡頭擷取範圍內，亦即所擷取之臉部影像當中臉部面積占整個臉部的比例大於預設(第一)臨界值；“清晰”影像係指所擷取影像足以讓影像處理器111進行影像處理，亦即所擷取之臉部影像的影像品質(image quality)大於預設(第二)臨界值。根據本實施例的特徵之一，在擷取到涵蓋完整臉部的清晰影像之前，閘道器11會鎖住輸出入裝置13的密碼輸入區312，不讓使用者鍵入密碼。In step 23, the gateway 11 controls the image capturing device 12 to capture at least one facial image of the user. If a clear image covering the entire face is not captured, the image capturing device 12 will continue to perform image capturing until the preset first period (for example, 30 seconds) is reached. In this specification, "complete" means that most (for example, 90%) of the face is within the lens capturing range of the image capturing device 12, that is, the captured facial image contains the face area of the entire face. The ratio of the part is greater than the preset (first) threshold; the “clear” image means that the captured image is sufficient for image processing by the image processor 111, that is, the image quality of the captured facial image is greater than Preset (second) threshold. According to one of the features of this embodiment, the gateway 11 locks the password input area 312 of the I/O device 13 before capturing a clear image covering the entire face, and prevents the user from entering the password.

於步驟24，檢視是否擷取到涵蓋完整臉部且清晰的臉部影像，亦即檢視臉部偵測是否成功。如果步驟24的檢視結果為否定且已達預設第一期間(例如30秒)，則閘道器11鎖住輸出入裝置13的觸控螢幕之(整個)頁面(步驟25)，使其暫時無法操作。當達到預設第二期間(例如3分鐘)後，流程回到步驟21。如果步驟24的檢視結果為肯定，則閘道器11釋放輸出入裝置13的密碼輸入區312(步驟26)，使得使用者可以從密碼輸入區312輸入密碼，且將所擷取到涵蓋完整臉部且清晰的臉部影像儲存於記憶裝置14。此時，輸出入裝置13的觸控螢幕顯示解鎖頁面32。第三B圖例示輸出入裝置13的解鎖頁面32，其中即時影像區311置換為解鎖通知313。In step 24, check whether a clear facial image covering the entire face is captured, that is, check whether the face detection is successful. If the check result in step 24 is negative and the preset first period (for example, 30 seconds) has elapsed, the gateway 11 locks the (entire) page of the touch screen of the I/O device 13 (step 25) to make it temporarily Unable to operate. When the preset second period (for example, 3 minutes) is reached, the process returns to step 21. If the check result in step 24 is affirmative, the gateway 11 releases the password input area 312 of the I/O device 13 (step 26), so that the user can input the password from the password input area 312, and the captured data covers the entire face The partial and clear facial image is stored in the memory device 14. At this time, the touch screen of the I/O device 13 displays an unlock page 32. The third diagram B illustrates the unlock page 32 of the I/O device 13, in which the instant image area 311 is replaced with the unlock notification 313.

於步驟27，閘道器11識別使用者所輸入之密碼是否正確(例如與記憶裝置14預先儲存的密碼進行比較)。如果步驟27的密碼識別失敗(表示目前使用者不具有資格進行保全設定的解除)，則閘道器11可藉由網路15(例如網際網路)發送警告通知(warning notification)給相關人士(例如相應智慧家庭網路的管理者)的行動裝置16(步驟29)。於發送警告通知時，也可同時發送使用者的臉部影像或儲存於記憶裝置14。In step 27, the gateway 11 recognizes whether the password entered by the user is correct (for example, it is compared with the password pre-stored in the memory device 14). If the password recognition in step 27 fails (indicating that the current user is not qualified to cancel the security setting), the gateway 11 can send a warning notification to the relevant person via the network 15 (such as the Internet) ( For example, the mobile device 16 corresponding to the manager of the smart home network (step 29). When sending a warning notification, the user's face image can also be sent or stored in the memory device 14 at the same time.

如果步驟27的密碼識別成功，表示目前使用者通過臉部偵測與密碼識別，則閘道器11解除相應智慧家庭網路的保全設定(步驟28)。在一實施例中，即使是保全設定已解除，閘道器11仍會將使用者的臉部影像儲存於記憶裝置14或傳送給相關人士。If the password recognition in step 27 is successful, it means that the current user passes face detection and password recognition, and the gateway 11 cancels the security setting of the corresponding smart home network (step 28). In one embodiment, even if the security setting is cancelled, the gateway 11 will still store the user's facial image in the memory device 14 or send it to the relevant person.

於一實施例中，更包含步驟30，閘道器11的影像處理器111將所擷取臉部影像與記憶裝置14的(預先儲存)資料庫141進行臉部辨識(facial recognition)。其中，資料庫141預先儲存有至少一具資格(admissible)使用者的臉部影像資料(例如臉部影像特徵值)。本實施例之影像處理器111可使用傳統的各種臉部辨識技術以進行臉部辨識，其細節不予贅述。In one embodiment, step 30 is further included. The image processor 111 of the gateway 11 performs facial recognition with the (pre-stored) database 141 of the captured facial image and the memory device 14. Wherein, the database 141 pre-stores facial image data (for example, facial image feature values) of at least one qualified (admissible) user. The image processor 111 of this embodiment can use various traditional facial recognition technologies to perform facial recognition, and the details will not be repeated.

如果步驟30的臉部辨識失敗(表示目前使用者不具有資格進行保全設定的解除)，則閘道器11可藉由網路15(例如網際網路)發送警告通知(warning notification)給相關人士(例如相應智慧家庭網路的管理者)的行動裝置16(步驟29)。於發送警告通知時，也可同時發送使用者的臉部影像或儲存於記憶裝置14。If the face recognition in step 30 fails (indicating that the current user is not eligible to cancel the security setting), the gateway 11 can send a warning notification to the relevant person via the network 15 (such as the Internet) (For example, the corresponding smart home network manager) mobile device 16 (step 29). When sending a warning notification, the user's face image can also be sent or stored in the memory device 14 at the same time.
