A novel semi-fragile audio watermarking scheme
The 2nd IEEE Internatioal Workshop on Haptic, Audio and Visual Environments and Their Applications, 2003. HAVE 2003. Proceedings., 2004In this paper, we present a semi-fragile audio watermarking technique which embeds watermark in the discrete wavelet domain of an audio by quantizing the selected coefficients. The quantization parameter used in the algorithm is user-defined. Different value of the quantization parameter affects the robustness of the watermark.

A Novel Semi-Fragile Document Watermarking Algorithm
2007 International Workshop on Anti-Counterfeiting, Security and Identification (ASID), 2007A novel document watermarking algorithm is proposed. In this algorithm a watermark is embedded into a WORD document by modifying the font color attribute. Experimental results show that this algorithm has good perceptual transparency, large capacity and security. It is robust to format change attacks and the WINRAR compress attack.

Semi-fragile watermarking algorithm based on bi-watermarking technology
2010 International Conference on Computer Application and System Modeling (ICCASM 2010), 2010A semi-fragile watermarking algorithm using bi-watermark is proposed in this paper. When embedding watermark, the original image was decomposed by 3-level discrete wavelet first, and then edge information of the third approximation coefficient was extracted using canny operator.

A New Semi-fragile Watermarking for Audio Authentication
2009 International Conference on Artificial Intelligence and Computational Intelligence, 2009This paper presents a new semi-fragile watermarking algorithm for audio authentication, which takes full advantage of scrambing algorithm. Watermark scrambling algorithm can dispel the pixel space relationship of the binary watermark image. After scrambing, the white pixels and black ones of original watermark image are comparatively orderliness, which

A Semi-fragile Watermarking for ROI Image Authentication
2008 International Conference on MultiMedia and Information Technology, 2008In this paper, a watermarking algorithm for ROI (Regions of Interesting) authentication and tamper detection is proposed. The watermarking is embedded in the DWT (Discrete Wavelet Transform) coefficients of the ROB (Regions of Background). The algorithm uses a hashing to detect whether the ROI of image is tampered, and then uses the watermarking to ...

A Semi-Fragile Image Watermarking Resisting to JPEG
Journal of Software, 2006Semi-Fragile watermark has attracted attention due to its important role in content authentication for multimedia. In order to differentiate incidental attacks and malicious attacks, semi-fragile watermark must be robust against content-protection image processing.

Holographic semi-fragile watermarking combined with asymmetric crytography
2008A semi-fragile watermarking technique, with a Computer Generated Hologram (CGH) coding system of the mark, is introduced and tested. The CGH watermarking is used for image authentication. The hologram of the mark is embedded in the spatial domain by a blind additive embedding technique.
