An improved fragile watermarking algorithm for JPEG images
In this paper a new fragile watermarking algorithm is proposed that is built upon the cryptanalysis of the CWSA algorithm (Chaotic Watermarking Scheme for Authentication of JPEG Images – Wang et al. [14]). The proposed algorithm preserves the advantages of CWSA, but is robust against cryptanalysis,...

description | In this paper a new fragile watermarking algorithm is proposed that is built upon the cryptanalysis of the CWSA algorithm (Chaotic Watermarking Scheme for Authentication of JPEG Images – Wang et al. [14]). The proposed algorithm preserves the advantages of CWSA, but is robust against cryptanalysis, faster and less perceptible. It uses two chaotic maps: the piecewise linear chaotic map and a chaotic generator composed of two perturbed recursive filters with a nonlinear function, the Skew Tent map. Experimental results show that the proposed algorithm provides good performances in terms of security, imperceptibility, speed and resistance to cryptographic attacks. |
