Abstract :
Nowadays watermarking is a popular tool for intellectual right protection. In this paper, a robust lossless watermarking method is anticipated based on applying fuzzy integral to find similarity between DCT coefficients of original image and watermark. The extraction phase does not require the original image and the watermark is extracted with help of secret key information. The experimental results confirmed that the proposed method was robust against various attacks such as compression, filtering, cropping, and additive Noise and the extracted watermark was visually similar to original one.
