Özet
The purpose of the Steganography is to hide and transfer secret or sensitive information/message in a multimedia medium, so that it can not be understood by unintended parties. In the literature there are variety of techniques utilizing spatial domain image steganography but enhanced steganography schemes are still needed for improving quality of stego-image. In the proposed work, a new spatial domain steganography scheme enhanced by chaotic maps is presented, namely Tent map, Logistic map, Bernoulli Map, Quadratic Map, Chebyshev map and Sine Map in different combinations to select the pixel location for hiding data. A compression is carried out on the secret message before hiding in the carrier image in order to improve secret message amount. Assessment of the proposed system is carried out not only with quality of the stego image statistical values like PSNR, MSE and histogram but also in terms of, entropy, correlation for each chaotic map. It is concluded from the statistical test results that the proposed scheme is imperceptible enough for hiding the information in a digital medium. Moreover the proposed system has passed rigorous Stego-Analysis tests with stego analysis tool Virtual Steganographic Laboratory (VSL)
