This is an incremental improvement for digital watermarking applications.
The paper tackles the problem of watermarking by introducing a new algorithm based on discrete chaotic iterations, which ensures topological chaos to satisfy desired properties for embedding watermarks in carrier media.
This paper introduces a new watermarking algorithm based on discrete chaotic iterations. After defining some coefficients deduced from the description of the carrier medium, chaotic discrete iterations are used to mix the watermark and to embed it in the carrier medium. It can be proved that this procedure generates topological chaos, which ensures that desired properties of a watermarking algorithm are satisfied.
