ABSTRACT
The conveyance of sensitive information over any media involves secured approach. The most frequentmethod for this process is cryptography which is reliable to certain extent only. To strengthen thereliability of communication, steganography is one available solution. If message is conveyed over animage(like JPEG) as embedding space by adjusting the quantization table value, the reliability is furtherstrengthened. Current article demonstrates this particular scheme involving few permutation algorithmswhich can be used for conveying sensitive information between sender and receiver. This dualcompression on an image gives fair results.
