This paper presents a scheme for estimating two-band amplitude scale attack within a quantization-based watermarking context. Quantization-based watermarking schemes comprise a class of watermarking schemes that achieves the channel capacity in terms of additive noise attacks 1. Unfortunately, Quantization-based watermarking schemes are not robust against(More)
Quantization-based watermarking schemes comprise a class of watermarking schemes that achieves channel capacity in terms of additive noise attacks. Unfortunately, quantization-based watermarking schemes are not robust against linear time invariant (LTI) filtering attacks. In this paper we concentrate on amplitude scaling of a multi-band system. First we(More)
