Abstract

This paper considers the problem of the inversion attack. We discuss a relation of a copyright owner and an attacker on an equal footing, the problem of the assumption of robustness, and the quantization error as a one-way function. Using an improved two-stage watermarking system, a framework that invalidates an inversion attack is proposed.
