The confidential information is communicated through the open channel in a covert way by using steganography. In this paper we propose the Covariance based Steganography using Discrete Cosine Transform (CSDCT) algorithm. The Average Covariance of the Cover Image (ACCI) is computed and threshold ACCI value is fixed at 0.15. The cover image is segmented into 8*8 cells and the Least Significant Bit (LSBs) are replaced by Most Significant Bits (MSBs) of payload based on ACCI values. It is observed that the capacity, Peak Signal to Noise Ratio (PSNR) and security is better compared to the existing algorithm. |
