Title:
ANTI-COUNTERFEIT METHOD
Document Type and Number:
WIPO Patent Application WO/2017/045594
Kind Code:
A1
Abstract:
An anti-counterfeit method, comprising: obtaining raw data to be encoded, simulating fingerprint data collecting to acquire initial fingerprint feature information, encrypting the initial fingerprint feature information to obtain a random feature key including a first sub-key and a second sub-key, encoding the first sub-key to generate a micro-texture image, fixing the second sub-key in an encryption program, and encrypting the raw data to be encoded by using the random feature key to generate an information code pattern including the micro-texture image. When an image sensor integrates the first sub-key and the second sub-key to generate the random feature key successfully, a security authentication is complete, and the image sensor decrypts the information code pattern by using the random feature key, so that decryption is done successfully.
