Authentication method for carrying out identity authentication on bank card holder on basis of fingerprint verification

Abstract

The invention discloses an authentication method for carrying out identity authentication on a bank card holder on the basis of fingerprint verification. The authentication method comprises the following steps that the fingerprint of a bank card owner is extracted, and is stored in a bank system database; when the bank card holder carries out payment through a bank card, a payment terminal extracts the fingerprint of the bank card holder, and sends the fingerprint of the bank card holder to a bank system center; the bank system center carries out matching verification on the fingerprint of the bank card holder and the fingerprint, stored in the bank system database, of the bank card owner; after matching verification is accomplished, the bank system center sends the verification result to the payment terminal; when the verification result shows that matching verification is successful, the payment terminal supports payment through the bank card. According to the technical scheme, the authentication method for carrying out identity authentication on the bank card holder on the basis of fingerprint verification has the advantages that the defects in the prior art are overcome, the fingerprints serve as verification information of payment of the bank card, and cannot be easily cracked, and the situation that a password is forgotten cannot exist.
