Abstract:

A chaotic map-based hybrid watermarking scheme incorporating the concepts of the Discrete Cosine Transform (DCT) and exploiting the stability of the singular values has been proposed here. Homogeneity Analysis of the cover image has been done to chalk out appropriates sites for embedding and thereafter, a reference image has been obtained from it. The singular values of the reference image has been modified for embedding the secret information. The Chaotic map based scrambling enhances the security of the algorithm as only the rightful owner possessing the secret key, could retrieve the actual image. Comprehensive set of attacks has been applied and robustness tested with the Normalized Cross Correlation (NCC) and Peak Signal to Noise Ratio (PSNR) metric values. High values of these metrics signify the appropriateness of the proposed methodology.
