Reversible watermark using difference expansion of triplets
A new reversible watermarking algorithm based on the difference expansion of colored images has been developed. Since the watermark is completely reversible, the original image ca...

Robust Embedded Data from Wavelet Coefficients
An approach to embedding gray scale images using a discrete wavelet transform is proposed. The proposed scheme enables using signature images that could be as much as 25% of the h...

Estimation of optimum coding redundancy and frequency domain analysis of attacks for YASS - a randomized block based hiding sche
Our recently introduced JPEG steganographic method called Yet Another Steganographic Scheme (YASS) can resist blind steganalysis by embedding data in the discrete cosine transform...
