Anti-counterfeiting using phosphor PUF

Anti-counterfeiting is a global problem. Brand owners suffer from huge losses due to counterfeits every year, and turn to advanced solutions to gain back control over their brands. An anti-counterfeiting system normally encodes a digital identifier in a physical identifier in essence. The physical identifier then is attached with the product. If the physical identifier is cloneable or reusable, the counterfeit products could easily cheat the anti-counterfeiting system. This paper continues our work on the anti-counterfeiting system applying phosphor physical uncloneable function (PUF). An offline anti-counterfeiting system is proposed in this paper prevailing over the previously proposed online system as it does not require any online database. Furthermore, a prototype software running on the commodity mobile phone of consumers for verification is designed.
