In this paper, we present three counterfeiting attacks on the block-wise dependent fragile
watermarking schemes. We consider vulnerabilities such as the exploitation of a weak …

Content-independent watermarks and block-wise independency can be considered as
vulnerabilities in semi-fragile watermarking methods. In this paper to achieve the objectives …

This paper presents two attacks on Teng et al.'s fragile watermarking algorithm. Both attacks
allow the attacker to apply valid watermarks on tampered images, therefore rendering the …

In this paper, we analyze a recently proposed semi-fragile watermarking scheme based on
local binary pattern (LBP) operators, and note that it has a fundamental flaw in the design. In …

A new fragile watermarking scheme for image authentication and location of areas that have
been tampered with is proposed in this paper. Based on a quadratic-residue theorem, the …

This paper proposes a block-chain based fragile watermarking scheme to address the issue
of security and accuracy of tamper localization. The relationship between the security …

In this paper, a novel fragile watermarking scheme based on the continued fraction
technique is proposed. The goal of this scheme is to verify the integrity of a watermarked …

Block-wise fragile watermarks can be used to reveal maliciously tampered areas in
multimedia products. However a forged content containing a cloned fragile watermark can …

Both security and tamper localization are essential for fragile watermarking techniques.
Embedded fragile watermark should be sensitive enough to cover images. But high …

It is recognized that block-wise dependence is a key requirement for fragile watermarking
schemes to thwart vector quantization attack. It has also been proved that dependence with …
