Research of Encryption Algorithm of Two-Dimensional Barcode Based on Pseudo Fingerprint Feature

摘要

By using the two-dimensional barcode encryption technology with pseudo fingerprint feature key, an asymmetric, encrypted and anti-fake design of two-dimensional barcode has been implemented. After being processed, the collected fingerprint information is used to set parameters, translated and rotated. With the accomplishment of coding the parameters, datas of pseudo-random fingerprint feature come into being. With the help of the RSA, encrypt the private key which is randomly produced by pseudo fingerprint feature to get a new one. With the new private key, the only information of owners is encrypted, solving the problem of "witness identity".
