  • Patent number: 11551482
    Abstract: Facial recognition-based authentication comprises obtaining a first image of a target object, updating projection information associated with a display by a display device, obtaining a second image of the target object, the second image being an image of the target object after the projection information is updated, obtaining an image difference data based at least in part on the first image and the second image, and determining whether the target object is a virtual object based at least in part on the image difference data.

  • Patent number: 10892896
    Abstract: An authentication request is sent to a server. An authentication request reply message is received from the server. A biometric feature input by a user is received. A biometric feature template identifier (ID) corresponding to the received biometric feature is acquired using the received biometric feature. The acquired biometric feature template ID is compared with a stored biometric feature template ID included in an enable record that is used for biometric feature verification and created during a biometric feature verification enabling process. When the two biometric feature template IDs are consistent, an authentication response message is generated. The authentication response message is sent to the server for verification. Verification includes comparing the biometric feature template ID in the authentication response message with the biometric feature template ID in a saved user record. The verification succeeds if the two biometric feature template IDs are consistent; otherwise an error is reported.

  • Patent number: 10885362
    Abstract: A face recognition method and apparatus, the method comprising: capturing a first image, the first image including a face content of a user and a background content; adjusting a relative position between an image capture device and the user; capturing a second image after the relative position is adjusted, the second image comprising a second face content of the user and a second background content; comparing the face content and the background content in the first image with those in the second image respectively and obtaining difference information; and determining that the user is an authentic user or an impostor according to the difference information. According to embodiments of the present application, the problem that current face liveness detection methods fail in recognizing impostors can be solved.

  • Patent number: 10721076
    Abstract: A method, a device, a terminal, and a service are described for a security check for terminal users. The method may include: performing a local check via an updated check mode to acquire a local check result, when a terminal user performs the security check; encrypting the local check result according to stored substitutive credential information to acquire an encrypted check result, wherein the substitutive credential information is generated when the updated check mode is used to replace an original check mode; and sending the encrypted check result, the local check result and user information of the terminal user to a server, so that the server determines that the local check result is trustable when the verification of the encrypted check result according to substitutive credential information corresponding to the user information is passed.
