Abstract
A method and an apparatus for privacy protection biometric authentication and an electronic device. The method comprises the following steps: constructing a corresponding a biological data template according to a biological information data set input by a user when registering; generating a pair of public key and private key by asymmetric cryptography technology; generating encrypted biological data by a secret sharing solution and OKVS technology according to the biological data template and the private key; sending the public key and the encrypted biological data to a server; recovering the private key by OKVS technology according to the biological data input by the user during authentication and the encrypted biological data; constructing a signature according to the recovered private key and the corresponding public key; sending the signature to the server, so that the server verifies the user according to the public key and the signature.
