Abstract
In order to design an efficient blind watermarking scheme, Eggers, et al. (2000) proposed the scalar Costa scheme (SCS). However, SCS, which is based on the uniform scalar quantizer, is vulnerable to the amplitude modification. In this paper, we propose an amplitude-modification resilient watermarking scheme, which is a modified SCS based on the A-law companding. By using the A-law companding, resilience against the amplitude modification can be achieved.
