This book intends to provide a comprehensive overview on different aspects of mechanisms
and techniques for information security. It is written for students, researchers, and …

This paper proposes a novel fragile watermarking scheme for JPEG image authentication.
The watermark is generated by folding the hash results of quantized coefficients, and each …

This paper proposes an integrated visual saliency-based watermarking approach, which
can be used for both synchronous image authentication and copyright protection. Firstly …

JPEG is the most common image format in smartphones, computers, or digital cameras.
Because numerous JPEG images are easily shared and distributed, there are privacy and …

This book describes the need of copyright protection for multimedia objects and develops an
invisible image watermarking scheme to serve the purpose of copyright protection. Here …

In this paper a new fragile watermarking algorithm is proposed that is built upon the
cryptanalysis of the CWSA algorithm (Chaotic Watermarking Scheme for Authentication of …

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 report results from comparative study on various related and relevant
aspects of the digital watermarking such as image authentication techniques using fragile …

In this paper a watermarking technique has been proposed. The proposed watermarking
technique has been incorporated in the JPEG compression standard. Unlike conventional …

Watermarking techniques are widely used for image authentication and copyright protection.
Weaknesses of the “A novel CRT-based watermarking technique for authentication of …
