New Semi-fragile Authentication Watermarking
2001In this paper we propose a semi-fragile watermarking scheme, which can be used for image authentication. Let the original image be performed by the l-level discrete wavelet transformation. Then the approximate wavelet coefficient matrix of the original image and the real-value chaotic sequences are used to generate the content-based and secure ...

A Fragile Software Watermarking for Tamper-Proof
2009 Fifth International Conference on Information Assurance and Security, 2009A fragile software watermarking scheme for integrity verification of software is proposed in this paper. The algorithm uses the idea of semantic-preserving code substitution for embedding the watermark. With the system, the generated watermark relates closely to the content of software, and the scheme has highly sensitive to different types of attacks.

A Survey of Semi-fragile Watermarking Authentication
2018In order to improve security and detection of tampered area, in the meantime be able to resist common image processing operation such as: JPEG, Gaussian Filter or other compression techniques, semi-fragile watermarking technology are considered to be the solution.

Speech Authentication by Semi-fragile Watermarking
2005This paper proposes a semi-fragile speech watermarking scheme by quantization of Linear Prediction (LP) parameters, i.e. the inverse sine parameters. The watermark decoding performance is analyzed by modelling the parameters estimation error as Laplace distributed noises.

Fragile Watermarking Scheme for Image Authentication
2012 5th International Conference on Human System Interactions, 2012In this paper, we propose a fragile watermarking scheme in wavelet domain which is sensitive to all kinds of modifications and has the ability to localize the tampered regions. The proposed scheme is a key-dependent, content based and non-deterministic neighborhood-dependent method so that it can resist the well-known attacks including the ...

Chaos-based self-embedding fragile watermarking with flexible watermark payload
Multimedia Tools and Applications, 2012This paper proposes a self-embedding watermarking scheme that reduces the watermark payload significantly while maintaining good recovery quality and security. The embedded watermark contributes to the tamper detection and content recovery and is composed of only the compression codes of the image content. The compression codes with variable length are

Fractal Based Fragile Watermark
2009 Second International Conference on Computer and Electrical Engineering, 2009The protection of ownership and the protection of unauthorized tampering of multimedia data (audio, image, video, and document) have become a major concern for the authors of multimedia. Image authentication verifies the originality of an image by detecting malicious manipulation The protection of ownership and the protection of unauthorized tampering ...

Fragile Watermarking Based on Localized Histogram Modification
2009 6th IEEE Consumer Communications and Networking Conference, 2009In this paper, we propose a fragile watermarking algorithm for image authentication and integrity. Existing fragile watermarking algorithms had to accept the image distortion in order to insert the watermark. To overcome this drawback, we propose a new fragile watermarking algorithm which can recover the original image after extracting the watermark ...

A numerically stable fragile watermarking scheme for authenticating 3D models
CAD Computer Aided Design, 2008 International audienceThis paper analyzes the numerically instable problem in the current 3D fragile watermarking schemes. Some existing fragile watermarking schemes apply the floating-point arithmetic to embed the watermarks. However, these schemes fail
