Closed-Form Formulas for Private Watermarking Capacities of Laplacian Sources with the Magnitude-Error Distortion Measure and Un
Calculation of watermarking capacities of private Laplacian watermarking systems with the magnitude-error distortion measure under fixed attacks is addressed. First, in the case o...

Fingerprinting Schemes. Identifying the Guilty Sources Using Side Information
In a fingerprinting scheme a distributor places marks in each copy of a digital object. Placing different marks in different copies, uniquely identifies the recipient of each cop...

Robustness Enhancement of Content-Based Watermarks Using Entropy Masking Effect
Image-Adaptive watermarking systems exploit visual models to adapt the watermark to local properties of the host image. This leads to a watermark power enhancement, hence an improv...

On the Achievable Rate of Side Informed Embedding Techniques with Steganographic Constraints
The development of watermarking schemes in the literature is generally guided by a power constraint on the watermark to be embedded into the host. In a steganographic framework the...

Performance Lower Bounds for Existing and New Uncoded Digital Watermarking Modulation Techniques
Abstract. Many coded digital watermarking systems development requires first the selection of a (uncoded) modulation technique to be part of a coded architecture. Therefore, perfo...
