Abstract
The steganography is a covert communication to transfer confidential information over an internet. In this paper we propose Adaptive Steganography based on Covariance and Discrete Cosine Transform (ASCDCT) algorithm. The Average Covariance of the Cover Image (ACCI) is computed. The ACCI of 0.15 is considered as the threshold value. The cover image is segmented into 8*8 cells and DCT is applied to derive coefficients. The payload Most Significant Bits (MSBs) are embedded into the cover image based on ACCI and DCT coefficients. It is observed that the capacity, Peak Signal to Noise Ratio (PSNR) and security is better compared to the existing algorithm.
