LOGO-Based Intellectual Property Right Protection Scheme for GANs on FPGA

In recent years, Generative Adversarial Networks (GANs) have become essential tools in artificial intelligence research. Field Programmable Gate Arrays (FPGAs) offer remarkable flexibility, high performance, and energy efficiency for deploying GANs. However, the open and reprogrammable architecture of FPGAs, despite its advantages, introduces risks of unauthorized access and reverse engineering. To address this challenge, this article presents a novel approach integrating Physical Unclonable Functions (PUFs) and logos to protect the Intellectual Property Rights (IPR) of GANs. Our method establishes a closed-loop conversion process where logos are transformed into PUF responses, generating unique identities fed into the GAN to reproduce the original logo. By embedding PUF response information into latent vectors, the generator produces images with embedded logos. Thanks to the uniqueness of PUF, a robust binding of the logo, FPGA, and GANs' IPR is implemented, allowing verification of the IPR with the assistance of a unique FPGA fingerprint, even when a publicly available logo is used. Experimental results show that embedding the logo does not change the performance of the original GANs, and the logo detection rate exceeds 90%. At the same time, the scheme can effectively resist brute force, fine-tuning and pruning attacks.
