[0038] The main scheme of the present invention is to combine the digital certificate and fingerprint authentication in the smart card to make the user's digital identity and physical identity correspond, and at the same time store the user digital certificate containing the corresponding private key in the smart card, and use the user fingerprint fuzzy vault The PIN of the smart card is encrypted, thereby achieving a highly secure identity authentication purpose. At the same time, in order to reduce the computational burden of the smart card, a secret sharing method is adopted. Distribute the alignment work to the fingerprint server, so that if and only when the information in the smart card and the server are available, the PIN of the smart card can be successfully recovered, thereby releasing the digital certificate containing the private key.
[0039] This solution solves the security bottleneck of smart cards, uses fingerprints to determine the identity of the holder, improv...
