Homomorphic and Commutative Fragile Zero-watermarking Based on SVD [PDF]
Most of the existing watermarking and encryption schemes are difficult to ensure the commutativity of watermarking and encryption as well as the visual quality of the protected image.These schemes complete watermark embedding and image encryption ...

Video Dual Watermarking Algorithm Based on Mean Ratio and Compressive Sensing [PDF]
In order to improve the information quality and anti-attack ability of video watermarking algorithm,a video dual watermarking algorithm is proposed.Robust watermark is constructed by robustness of selecting block global mean and block mean.Based on ...

Fragile IP Watermarking Techniques [PDF]
Intellectual property (IP) blocks reuse is essential for facilitating the design process of system-on-a-chip. Sharing IP designs still poses significant high security risks not only to copyright but also to design authenticity. Intruders, or even competitors, can make design changes to IPs, which can lead to the loss of the ownerpsilas credibility.

Reversible and Fragile Watermarking for Medical Images [PDF]
A novel reversible digital watermarking technique for medical images to achieve high level of secrecy, tamper detection, and blind recovery of the original image is proposed. The technique selects some of the pixels from the host image using chaotic key for embedding a chaotically generated watermark. The rest of the pixels are converted to residues by

Evaluation of a Framework for Robust Image Reversible Watermarking
In the literature, robust reversible watermarking schemes (RWSs) allow the extraction of watermarks after the images have suffered attacks; however, the modified images are compromised.

A Fragile Image Watermarking Scheme in DWT Domain Using Chaotic Sequences and Error-Correcting Codes
With the rapid development of digital signal processing tools, image contents can be easily manipulated or maliciously tampered with. Fragile watermarking has been largely used for content authentication purposes. This article presents a new proposal for

A single watermark based scheme for both protection and authentication of identities
The security of a watermarking scheme is mainly categorised as either robust or fragile. The former can withstand an authorised alteration/attack, primarily used in copyright protection.

In this paper, we explore the advantages of a fractional calculus based watermarking system for detecting Gaussian watermarks. To reach this goal, we selected a typical watermarking scheme and replaced the detection equation set by another set of ...
