Non blind digital watermarking technique using DCT and cross chaos map
C Pradhan, V Saxena, AK Bisoi - … International Conference on …, 2012 - ieeexplore.ieee.org
Digital watermarking is the process of embedding secret information into a digital signal
which may be used to verify its authenticity or the identity of its owners. In this paper, a non-
blind digital image watermarking algorithm based on Discrete cosine transform, Cross
chaotic map and Arnold transform has been described. Initially, Arnold's transformation is
applied on the watermark signal. Then, Cross chaos sequence is applied on this encrypted
watermark to encrypt further. Discrete cosine transformation is applied to the cover image to …
