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.

Fragile logo watermarking for public authentication
2008 IEEE International Conference on Acoustics, Speech and Signal Processing, 2008A new fragile logo watermarking scheme is proposed for public authentication and integrity verification of images. The security of the proposed block-wise scheme relies on a public encryption algorithm and a hash function. The encoding and decoding methods can provide public detection capabilities even in the absence of the image indices and the ...

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.

A Fragile Watermarking Based on Knapsack Problem
2004In this paper, a new fragile watermarking is proposed. It is different from most existing schemes to resist the famous birthday attack. The classic NPC problem knapsack problem in algorithm is introduced. It uses a random sequence to encrypt the bit planes of image pixels and regard the encrypted result as the indicative vector for knapsack set. The NP

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 ...

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.

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

Self-recovery Fragile Watermarking Scheme with Variable Watermark Payload
2012To take into account security, invisibility and recovery quality, this work proposes a variable-payload self-recovery fragile watermarking scheme. For each block, the watermarks include the total-watermark with variable number of bits and the basic-watermark of length 24 bits.

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 ...
