Watermarking Scheme Based on Multiple Chaotic Maps
a watermarking scheme for Grayscale image isproposed based on a family of the chaotic maps and discretecosine transform. Jacobian Elliptic mapis employed to encrypt ofwatermarked logo. Piecewise nonlinear chaotic map is also usedto determine the location of DCT coefficients for the watermarkembedding. The purpose of this algorithm is to improve theshortcoming of watermarking such as small key s...

متن کاملDigital Information Transmission Using Discrete Chaotic Signal
In this work the authors thoroughly investigated a digital information transmission system using discrete chaotic signal over cable. As an example in their work the authors consider the non-autonomous 2nd order non-linear oscillator system presented in Tamaševičious, Čenys, Mycolaitis, and Namajunas (1998) which is particularly suitable for digital communications and present the experimental re...
متن کاملHybrid Watermarking Scheme for Copyright Protection using Chaotic Maps Cryptography
Nowadays, there is an explosive growth in the digital multimedia creation, capturing, processing and distribution. Protecting the multimedia contents from copyright infringement has become a major concern. Encryption and watermarking are two complementary techniques that are used for protecting the multimedia data. In this paper, a proposed hybrid encryption-watermarking algorithm for copyright...
