在某個場景下採集的用戶的人臉資訊可能被採集方濫用於其他場景，危及用戶的財產和信用安全。例如，用戶在辦理酒店入住時向酒店提供的人臉資訊被洩露，不法分子使用用戶的人臉資訊盜刷信用卡，給用戶造成財產損失。
為此，本發明的核心思想是，將顯示有用戶的臉部以及場景錨定對象的用戶圖像提交給區塊鏈進行存證，以證明用戶僅授權在目標場景下使用其人臉資訊。如此，如果用戶在目標場景下提供的人臉資訊被濫用於其他場景，用戶進行維權時並不會遭遇舉證難的問題。
為了使本領域技術人員更好地理解本說明書實施例中的技術方案，下面將結合本說明書實施例中的附圖，對本說明書實施例中的技術方案進行詳細地描述，顯然，所描述的實施例僅僅是本說明書的一部分實施例，而不是全部的實施例。基於本說明書中的實施例，本領域普通技術人員所獲得的所有其他實施例，都應當屬於保護的範圍。
以下結合附圖，詳細說明本說明書各實施例提供的技術方案。
圖1是本說明書實施例提供的一種基於區塊鏈對人臉資訊進行場景化存證的方法的流程示意圖，包括如下步驟：
S100：當需要在目標場景下採集用戶的人臉資訊時，採集用戶圖像。
在本說明書實施例中，所述目標場景是指當前需要採集用戶的人臉資訊的業務場景。例如，用戶前往酒店辦理入住，酒店管理方需要採集用戶的人臉資訊進行身份驗證，此業務場景就可以是目標業務場景。
本方法的執行主體可以具有圖像採集功能與資料發送功能的設備，本文將之稱為處理設備。所述處理設備可以是用戶自己擁有的設備，也可以是所述目標場景提供的設備。此外，所述處理設備一般需要安裝與區塊鏈網路進行資料交互的客戶端。
所述用戶圖像是顯示有所述用戶的臉部與場景錨定對象的圖像，所述場景錨定對象用於證明所述用戶圖像是在所述目標場景下採集的。
所述用戶圖像一般是在所述用戶與所述場景錨定對象都位於採集範圍內時進行採集的。所述場景錨定對象可以是能夠證明所述用戶圖像是在所述目標場景下進行的採集的任何人或物。
例如，所述場景錨定對象可以是所述目標場景的管理人，例如酒店的大堂經理（佩戴有工作證，可確定無疑地證明大堂經理的身份）。
又如，所述場景錨定對象可以是用戶書寫的一張聲明，聲明具體為“本次人臉資訊採集僅用於本次酒店入住事宜”。
又如，具體地，所述場景錨定對象可以是展示有所述目標場景的相關資訊的展示設備。
以酒店入住場景為例。酒店可以在大堂擺設一台落地顯示螢幕，所述用戶到達酒店大堂請求辦理入住時，酒店管理方可以控制落地顯示螢幕顯示“用戶A於2019年1月20日到達酒店B辦理入住標準間205”。此落地顯示螢幕就是場景錨定對象。用戶可以與此落地顯示螢幕站在一起，由處理設備採集用戶圖像。
S102：將所述用戶圖像提交給區塊鏈網路進行存證。
處理設備可以透過安裝的區塊鏈客戶端，將所述用戶圖像提交到區塊鏈網路進行存證。
由於所述用戶圖像中顯示有用戶的臉部圖像以及場景錨定對象，而臉部圖像實際上包含有用戶的人臉資訊，因此也就實現了對用戶的人臉資訊進行場景化存證。
透過圖1所示的方法，當需要在目標場景下採集用戶的人臉資訊時，採集顯示有用戶的臉部與場景錨定對象的用戶圖像，然後對所述用戶圖像進行區塊鏈存證。如此，由於所述用戶圖像可以證明所述用戶僅授權在目標場景下使用自己的人臉資訊，因此，所述用戶圖像一旦被寫入區塊鏈，就相當於為後續可能出現的人臉資訊濫用事件提供可信的證據，降低所述用戶取證的難度。
此外，在步驟S102中，處理設備可以獲取當前的時間戳，然後將所述時間戳與所述用戶圖像綁定後提交給區塊鏈網路進行存證。如此，可以明確採集所述用戶圖像的時間，也就是明確所述用戶授權在目標場景下進行人臉採集的時間。
在本說明書實施例中，在目標場景下，對所述用戶進行身份驗證有以下兩種情況：
1、根據所述用戶圖像，確定所述用戶的人臉資訊，確定的人臉資訊用於對所述用戶進行身份驗證。具體地，可以從所述用戶圖像中截取所述用戶的臉部圖像，然後從臉部圖像中提取出所述用戶的人臉資訊。
進一步地，在步驟S102中，可以當確定所述用戶通過身份驗證時，才將所述用戶圖像提交給區塊鏈網路進行存證。
2、在採集用戶圖像之前，先採集用戶的人臉資訊進行身份驗證，如果用戶身份驗證通過進行身份驗證，則採集用戶圖像進行區塊鏈存證。
圖2是本說明書實施例提供的場景化存證示意圖。如圖2所示，如果用戶在目標場景下提供的人臉資訊被濫用於其他場景，用戶可以使用存證于區塊鏈中的用戶圖像向法院舉證，進行維權。

For example, the facial information provided by the user to the hotel during check-in is leaked, and criminals use the user's facial information to steal credit cards, causing property losses to the user.
To this end, the core idea of the present invention is to submit the user image showing the user's face and the scene anchored object to the blockchain for storage to prove that the user is only authorized to use his face information in the target scene. In this way, if the face information provided by the user in the target scene is abused in other scenes, the user will not encounter difficulty in proof when defending rights.
In order to enable those skilled in the art to better understand the technical solutions in the embodiments of this specification, the technical solutions in the embodiments of this specification will be described in detail below in conjunction with the drawings in the embodiments of this specification. Obviously, the described implementation The examples are only a part of the embodiments of this specification, not all the embodiments. Based on the embodiments in this specification, all other embodiments obtained by a person of ordinary skill in the art should fall within the scope of protection.
The technical solutions provided by the embodiments of this specification are described in detail below in conjunction with the drawings.
Fig. 1 is a schematic flow chart of a method for scene-based storage of facial information based on blockchain according to an embodiment of this specification, including the following steps:
S100: When the user's face information needs to be collected in the target scene, the user's image is collected.
In the embodiment of this specification, the target scene refers to a business scene in which facial information of a user needs to be collected currently. For example, if a user goes to a hotel to check in, the hotel manager needs to collect the user's face information for identity verification. This business scenario can be the target business scenario.
The execution subject of this method can be a device with image acquisition function and data transmission function, which is referred to as processing device in this article. The processing device may be a device owned by the user, or a device provided by the target scene. In addition, the processing equipment generally needs to install a client for data interaction with the blockchain network.
The user image is an image showing the face of the user and a scene anchor object, and the scene anchor object is used to prove that the user image is collected in the target scene.
The user image is generally collected when both the user and the scene anchored object are within the collection range. The scene anchoring object may be any person or thing that can prove that the user image is collected in the target scene.
For example, the scene anchor object may be a manager of the target scene, such as a lobby manager of a hotel (worn with a work card, which can definitely prove the identity of the lobby manager).
For another example, the scene anchor object may be a statement written by the user, and the statement is specifically "This face information collection is only used for this hotel stay."
For another example, specifically, the scene anchor object may be a display device that displays relevant information of the target scene.
Take the hotel check-in scenario as an example. The hotel can set up a floor-to-ceiling display screen in the lobby. When the user arrives at the hotel lobby to request check-in, the hotel manager can control the floor-to-ceiling display screen to display "User A arrives at Hotel B on January 20, 2019 to check in standard room 205" . This landing screen is the anchoring object of the scene. The user can stand with this floor-to-ceiling display screen, and the processing equipment collects user images.
S102: Submit the user image to the blockchain network for storage.
The processing device can submit the user image to the blockchain network for storage through the installed blockchain client.
Since the user image displays the user's face image and the scene anchor object, and the face image actually contains the user's face information, the user's face information is scened. Deposit evidence.
Through the method shown in Figure 1, when the user's face information needs to be collected in the target scene, the user image showing the user's face and the scene anchor object is collected, and then the user image is blockchain-chained Deposit evidence. In this way, since the user image can prove that the user is only authorized to use his face information in the target scene, once the user image is written into the blockchain, it is equivalent to the person who may appear in the future. The Facebook abuse incident provides credible evidence and reduces the difficulty of obtaining evidence for the user.
In addition, in step S102, the processing device may obtain the current timestamp, and then bind the timestamp with the user image and submit it to the blockchain network for verification. In this way, the time when the user image is collected can be clarified, that is, the time when the user is authorized to collect the face in the target scene.
In the embodiment of this specification, in the target scenario, the user is authenticated in the following two situations:
1. Determine the face information of the user according to the user image, and the determined face information is used to authenticate the user. Specifically, the facial image of the user can be intercepted from the user image, and then the facial information of the user can be extracted from the facial image.
Further, in step S102, when it is determined that the user passes the identity verification, the user image can be submitted to the blockchain network for verification.
2. Before collecting the user's image, first collect the user's face information for identity verification. If the user's identity is verified, the user's image is collected for blockchain storage.
Fig. 2 is a schematic diagram of a scenario-based evidence storage provided by an embodiment of this specification. As shown in Figure 2, if the face information provided by the user in the target scene is abused in other scenes, the user can use the user's image stored in the blockchain to provide evidence to the court for rights protection.
Fig. 3 is a schematic structural diagram of a device for scene-based storage of facial information based on blockchain according to an embodiment of the present specification, including:
The collection module 301 collects a user image when it needs to collect the user's face information in the target scene; the user image displays the user's face and the scene anchor object, and the scene anchor object is used for To prove that the user image was collected in the target scene;
The deposit certificate module 302 submits the user image to the blockchain network for deposit certificate.
The scene anchor object specifically includes:
A display device displaying relevant information of the target scene.
The certification module 302 obtains the current time stamp; binds the time stamp with the user image and submits it to the blockchain network for certification.
The device also includes:
The facial information determining module 303 determines the facial information of the user according to the user image, and is used to authenticate the user.
The certification module 302, when it is determined that the user passes the identity verification, submits the user image to the blockchain network for certification.
The device also includes:
The identity verification module 304 collects face information of the user before collecting the user image, and performs identity verification on the user according to the collected face information;
The collection module 301 collects user images if the user passes the identity verification.
