Improving LSB steganalysis using marginal and joint probabilistic distributions
The goal of steganalysis is to search for the presence of hidden information in numerical contents. This paper is based on a previous LSB steganalysis scheme for digital images th...

Perturbed quantization steganography with wet paper codes
In this paper, we introduce a new approach to passive-warden steganography in which the sender embeds the secret message into a certain subset of the cover object without having t...

Key-dependency for a wavelet-based blind watermarking algorithm
When a host image is watermarked multiple times by the same algorithm collisions can occur. This makes it difficult for an image to host multiple watermarks. But this hosting is n...
