A Maximum Entropy-Based Chaotic Time-Variant Fragile Watermarking Scheme for Image Tampering Detection

Entropy, 2013
The fragile watermarking technique is used to protect intellectual property rights while also providing security and rigorous protection. In order to protect the copyright of the creators, it can be implanted in some representative text or totem. Because

Adaptive Watermarking Scheme Using Biased Shift of Quantization Index

Journal of Electrical and Computer Engineering, 2010
We propose a watermark embedding and extracting method for blind watermarking. It uses the characteristics of a scalar quantizer to comply with the recommendation in JPEG, MPEG series, or JPEG2000.

An Asymmetric Watermarking Method in the DCT Domain Based on RC4-Permutation and Chaotic Map

Journal of ICT Research and Applications, 2013
This paper presents an asymmetric watermarking method in the DCT domain for still images based on permutation and chaos. This method uses secret watermark as private key and public watermark as public key.
