An Innovative Approach in Steganography
Journal Title: Scholars Journal of Engineering and Technology - Year 2014, Vol 2, Issue 2
Abstract
The secure data transmission over internet is achieved using Steganography. In this paper, a new algorithm based on the CPT- has been proposed for data hiding in a image. Here, no is used key for embedding and extracting of data. It hides four bits in a block of size 5×5 by changing a maximum of two bit. Better visual quality can be achieved by the proposed algorithm. The experimental results demonstrate the proposed algorithm’s effectiveness in resistance to steganalysis with better visual quality. Simulation experiments show that the proposed watermarking algorithm mis robust and invisible against the common signal processing techniques including JEPG compressing, noise, low-pass filter, median filter, contrast enhance, and the geometric distortions of transpose, mirror reflection, rotation and scale.. Keywords: data transmission, Steganography, JEPG compressing, noise, low-pass filter,
