Steganography is a technique of hiding information in an image. The overhead in terms of increased transmission time is reduced by compressing the image. Absolute Moment Block Truncation Coding (AMBTC) technique is one of the lossy image compression techniques. In this paper, AMBTC technique is used to hide the information as part of compressed image. The performance of the proposed approach is analyzed in terms of Compression Ratio, Elapsed Time and PSNR. When tested with different images, the proposed method outperforms the few existing methods.
