Abstract

See full text

An anti-counterfeit method includes: obtaining raw data to be encoded; collecting fingerprint data by analogue acquisition to obtain initial fingerprint feature information and encrypting the initial fingerprint feature information to obtain a random feature secret key, the random feature secret key comprising a first sub secret key and a second sub secret key and the first sub secret key is encoded into a micro-texture image while the second sub secret key is embedded in an encryption program; encrypting, through the random feature secret key, the raw data to be encoded to generate an information code image, the information code image comprising the micro-texture image; passing an anti-counterfeit authentication when an image sensor succeeds in integrating the first sub secret key and the second sub secret key to generate the random feature secret key; and succeeding in decrypting, by the image sensor, the information code image through the random feature secret key.
