  • Patent number: 12347234
    Abstract: Embodiments of this application provide a face image verification method performed by an electronic device, and a storage medium. In the embodiments of this application, a face image transmitted by a target device is received; then a residual fingerprint of the face image is extracted; then the device fingerprint information corresponding to the target device is obtained from a fingerprint information library, the fingerprint information library containing device fingerprint information corresponding to at least one verified device; then a device fingerprint component corresponding to the residual fingerprint information is obtained from the device fingerprint information according to position indication information of the face image, and a degree of correlation between the residual fingerprint information and the device fingerprint component is calculated; and when the degree of correlation is greater than or equal to the preset threshold, it is determined that the face image passes verification.

  • Patent number: 12235996
    Abstract: A security architecture system includes a plurality of subsystems. The plurality of subsystems include a secure element subsystem. A first subsystem of the plurality of subsystems includes a trusted computing platform that has a trusted platform control module. The first subsystem is configured to, for a running object in one or more subsystems other than the first subsystem in the plurality of subsystems, use the trusted platform control module to perform security measurement on the running object based on a measurement strategy and a measurement benchmark value to obtain a measurement result. The measurement result is used to control a running state of the running object in one or more subsystems other than the first subsystem in the plurality of subsystems.

  • Publication number: 20230068658
    Abstract: A microprocessor includes a cryptographic engine and a controller. The cryptographic engine is configured to execute a cryptographic algorithm. The controller is connected to the cryptographic engine. The controller is configured to receive an access request from a first execution environment. The access request accesses the cryptographic engine to execute the cryptographic algorithm. The access request includes at least identification information. The identification information indicates that the access request is from the first execution environment. The first execution environment is an execution environment of a number N execution environments. N is an integer greater than or equal to 1. The controller is further configured to, based on the identification information, instruct the cryptographic engine to execute the cryptographic algorithm that needs to be executed required by the access request.

  • Publication number: 20230069781
    Abstract: A microprocessor includes a cryptographic engine, M buffer units, and a controller. The cryptographic engine is configured to execute cryptographic algorithms. The M buffer units are configured to cache data required by an access request of a corresponding execution environment. M is an integer greater than or equal to 1. The controller is connected to the cryptographic engine and the M buffer units. The controller is configured to receive the access request from a first execution environment and instruct the cryptographic engine to execute the cryptographic algorithm requested by the access request using the required data cached by the buffer unit corresponding to the first execution environment from which the access request comes. The access request is used to access the cryptographic engine to execute a cryptographic algorithm. The first execution environment is one execution environment among N execution environments. N is an integer greater than or equal to 1.
