摘要：The growth of high speed computer networks and that of the Internet, in particular, has increased the ease of Information Communication. As information exchange plays an important role in today’s life, information security becomes more important and steganography is one of the methods to achieve security. Steganography is one of popular techniques used to hide the confidential information in images without being detected by human eyes. We described the use of Steganography along with 2k correction method & edge detection method in this paper. This technique proves to be better than earlier techniques because of its capability of carrying more payloads with better imperceptibility. This can be achieved by embedding more data in edge areas as compared to smooth areas of the image as human eye cannot detect the distortion at edges easily. The proposed algorithm yields better PSNR values as compared to previous algorithms
