2results about How to "Improve identity authentication efficiency" patented technology

Embodiments of the present application provide an identity authentication method and device, a storage medium and an electronic device. The method comprises: in response to a play instruction associated with a target action, obtaining K frames of face images to be processed, and then inputting the K frames of face images into a pre-trained recognition model respectively to obtain K recognition results, wherein each of the K recognition results comprises a probability of whether a frame of face image input is a real face and a probability of whether a target part of the frame of face image is in a target state, and the target part comprises different face parts performing different target actions; and then performing authentication on a face to be recognized according to the K recognition results to obtain a target authentication result, wherein the target authentication result comprises whether the face to be recognized is a real face and whether the face to be recognized performs the target action. Through the present application, the problem that identity authentication is too dependent on key point positioning accuracy in related art, resulting in low accuracy and efficiency of identity authentication, can be solved.

The application discloses an agent identity authentication method based on a domain name system, an agent identity registration method based on the domain name system and related equipment. The authentication method comprises the following steps: a first agent receives a service request message sent by a second agent, the service request message comprising a request signature, a first resolution domain and a first hash value; a query is initiated to a domain name system based on the first hash value and the first resolution domain, an extended resource record AIR corresponding to the second agent is obtained, and the extended resource record AIR comprises a public key of the second agent; a second hash value is obtained according to the public key, the consistency of the second hash value and the first hash value is verified, the legality of the request signature is verified according to the public key; and in the case that the second hash value is the same as the first hash value and the verification of the request signature is passed, it is determined that the identity authentication is successful. The method combines the distributed resolution capability of the domain name system with the self-authentication mechanism, and improves the efficiency of the agent identity authentication.
