Reducing the Complexity of Syndrome Coding for Embedding goal is to keep the embedding efficiency constant, i.e., to embed less complexly without increasing the average number of embedding changes, compared to the classic Matrix Embedding scenario..Generally, our considerations are based on structured codes, especially on BCH Codes. However, they are not

Exploiting Security Holes in Lattice Data Hidingsecurity is quantified in an information-theoretic sense by means of the information leakage between the watermarked signals seen by the attacker and the secret key used in the embedding process. The theoretical analysis accomplished in the first part of the paper addresses important issues such as

Practical Security Analysis of Dirty Paper Trellis Watermarkinging the principles of message embedding with DPT watermarking, the secret parameters of the scheme are highlighted. The security weaknesses of DPT watermarking are then presented: in the watermarked contents only attack (WOA) setup, the watermarked data-set exhibits clusters corresponding to the dif

Traffic Analysis Attacks on a Continuously-Observable Steganographic File Systemble deniability even when the raw storage device is continuously monitored by an attacker. Zhou, Pang and Tan have proposed such a system in [7] with a claim of provable security against traffic analysis. In this paper, we disprove their claims by presenting traffic analysis attacks on the file upda

Noise Robust Speech Watermarking with Bit Synchronisation for the Aeronautical Radioircraft, so far always transmitted verbally, could be embedded as a watermark in the speech signal and thereby prevent safety-critical misunderstandings. The first part of this paper presents an overview on this watermarking application. The second part proposes a speech watermarking algorithm that

A Geometrical Robust Image Data Hiding Scheme Using FCA-Based Resynchronization position of the center of gravity of each Delaunay triangle is embedded inside the red channel of the corresponding triangle. This information called synchronization information is afterward decoded robustly by fast correlation attacks used commonly in cryptanalysis. The synchronization information

Optimization of Tardos’s Fingerprinting Codes in a Viewpoint of Memory Amountcode uses certain continuous probability distribution, which causes that huge amount of extra memory is required in a practical use. An essential solution is to replace the continuous distributions with finite discrete ones, preserving the security. In this paper, we determine the optimal finite dis
