Anti-counterfeit has becoming a worldwide research focus with the proliferation of fake and inferior. Existing digital anti-counterfeiting technology has been difficult to go a long way, mainly because of its low code security, mutual authentication lacking, and long-term faced security loopholes such as recycling, batch copy and database attack fraud. A novel digital anti-counterfeiting scheme is proposed based on chaotic cryptography in this paper. The commodity anti-counterfeiting code and verification code are generated using a new chaotic encryption algorithm, and a new type of checking algorithm is presented which supports multiple and repeat query, so as to form an anti-counterfeiting scheme of “two codes, mutual authentication”. Then a digital anti-counterfeiting system is constructed to realize intelligent identification. It is proved that the proposed anti-counterfeiting scheme is effective, practical and reliable.
