Secure Steganographic Methods for Palette Imagesroduced the concept of optimal parity assignment for the color palette and designed an efficient algorithm that finds the optimal parity assignment. The optimal parity is independent of the image histogram and depends only on the image palette. Thus, it can be used for increasing the security of ste

Zero Knowledge Watermark Detection watermark within an object, in order to prove ownership or detect theft of said object, may open the door to subsequent theft, by providing attackers with the information they need to remove the watermark.

Proving Ownership of Digital Contentetectable, and thus deterring people from misuse, is the most promising measure currently known. To achieve this, most proposals apply watermarking techniques and focus on resolving the ownership in disputes which may arise after a misuse has been detected. Here a trusted third party (judge) compare

Error- and Collusion-Secure Fingerprinting for Digital Datal data can be done by watermarking techniques, which are mainly a branch of signal processing. Most watermarking methods, however, do not treat colluding adversaries who have obtained more than one copy, compare their copies, see differences and use this information to make a copy without a fingerpr

Computing the Probability of False Watermark Detectiona predefined watermark vector, and comparing the result against a threshold. We show that, if the probability density function of vectors that arise from random, unwatermarked media is a zero-mean, spherical Gaussian, then the probability that such a detector will give a false detection is given exa

Optimum Decoding of Non-additive Full Frame DFT Watermarksmain according to an additive-multiplicative rule. The structure of the optimum decoder is derived based on statistical decision theory. The Neyman-Pearson criterion is used to minimize the probability of missing the watermark for a given false detection rate. Experimental results highlights the sup
