The application provides method of registering a biometric identity and authenticating a biometric identity. The method is applicable to user equipment. The method comprises: transmitting to a service server a registration information request message comprising a service account identifier, receiving from an authentication server a registration information response message comprising a virtual account identifier; after biometric data passes a local identity verification, encapsulating into a registration request message an equipment identifier, the virtual account identifier, a biometric token and a biometric verification type corresponding to the biometric data that has passed the local identity verification, and a generated service public key; signing, using an equipment private key, the registration request message, and transmitting the same to the service server for the authentication server to store, after the forwarded registration request message passes a verification using an equipment public key, correspondence of the equipment identifier, the virtual account identifier, the biometric token, the biometric verification type, and the service public key for identity verification. The technical solution in the invention enhances security of registration and authentication processes.
