The Method of non-variable similarity code generation and key approach control using fingerprint template

摘要

The present invention provides a high security haejugo, a single fingerprint to the entire process to create constant pseudocode from one fingerprint information to give provide the convenience of being processed, and using the same by protecting the key to the constant pseudo code obtained by the fingerprint information of the user relates to a key access control method, this invention generates a value of the heat pair of the matching by the matching of the two fingerprint information to the storage in storage system files, and stores the information in the fingerprint registration N single fingerprint input and one-way function, using a conversion filter encrypts the key to generate a constant pseudocode. Further, decoding the fingerprint when keys by performing authentication with the input fingerprint information with the stored fingerprint information when the user authentication, generates a hit pair, using the stored fingerprint information, and create a new constant pseudo-code using a conversion filter thereby.
