Embodiment Construction

[0025] At present, whether it is a debit card or a credit card in domestic banks, more and more financial card thefts have occurred due to various reasons such as card duplication. If the combination of iris and CPU cards is used, the theft of credit cards can be basically eliminated. Events are also extremely beneficial to the development of financial cards! The specific implementation method is that the bank uses a card issuer and a separate iris encryption key to issue a CPU card with its own iris data to individual users, and combines iris information with personal bank information. In the process of use, the individual uses the terminal. First, the individual swipes the card, reads the relevant card information into the terminal, and then lets go, performs iris recognition, and then can perform related financial operations. Since iris recognition technology is difficult to replicate, this solution can effectively curb the occurrence of financial fraud and improve the safe...

Description

technical field [0001] The invention relates to a scheme capable of expanding the number of iris recognition users, and belongs to the technical field of third-generation biometrics recognition. Background technique [0002] In the existing technologies, most of them adopt card-type management, and more advanced ones adopt biotechnology for verification management, and iris recognition biotechnology has just developed in this field. Iris recognition is a kind of biometric recognition, which belongs to biometrics. The iris recognition system first obtains the personal iris distribution map through the iris recognition device, extracts the characteristic value from the iris distribution map according to the special comparison algorithm, and obtains the image of the iris through the infrared CCD camera. The digital image of the iris is stored in the computer system, and the feature values ​​are stored. During iris comparison, the iris map is taken in real time to extract featu...
