Watermarking of Digital Images Based on Logistic Mapping

doi:10.3969/j.issn.1000-1565.2010.02.020

Abstract

Abstract: The digital watermark images based on Logistic mapping are intruduced. DCT is used to embed confusional serial in DC. On account of HVS's conceal character, the watermark is self-adaptative to the image. So the invisibility of the watermark is guaranteed. In addition, the watermark can be checked. The experimental result suggests that the algorithmic stability is very good to the familiar signal distortion and geometrical distortion.

Key words: chaos, digital watermark, DC, HVS, DCT.
