Mathematical model of printing-imaging channel for blind detection of fake copy detection patterns
This addresses anti-counterfeiting for physical object protection, but appears incremental as it builds on existing CDP technology with a new model and scheme.
The authors tackled the problem of authenticating copy detection patterns (CDP) against deep learning-based attacks by proposing a new mathematical model of the printing-imaging channel and a detection scheme, resulting in reliable authentication of unknown deep learning-created fakes using only digital references.
Nowadays, copy detection patterns (CDP) appear as a very promising anti-counterfeiting technology for physical object protection. However, the advent of deep learning as a powerful attacking tool has shown that the general authentication schemes are unable to compete and fail against such attacks. In this paper, we propose a new mathematical model of printing-imaging channel for the authentication of CDP together with a new detection scheme based on it. The results show that even deep learning created copy fakes unknown at the training stage can be reliably authenticated based on the proposed approach and using only digital references of CDP during authentication.
