Majdi Al-qdah . Hybrid Security System based on Wavelet Domain Watermarking and Chaotic Map Cryptography. International Journal of Computer Applications. 110, 13 ( January 2015), 1-6. DOI=10.5120/19373-9190
This paper presents a novel hybrid security system that combines wavelet based watermarking with block based chaotic maps cryptography. A watermark is chaotically encrypted before being embedded in the detail coefficients of the wavelet transformed cover image. Using the developed system, the potential of embedding more than one watermark inside one cover image is investigated. The results indicate that combining watermarking and cryptography gives an added layer of security. Also, even though embedding more than one watermark is more robust to attacks it can potentially distort small size cover images.
