Shifali Dua, Faisal *

Abstract


Steganography is the strategies for concealing an information or message inside another message or cover picture without attracting any suspect to the others and that he message must be identified by its expected beneficiary. In current terms, steganography is generally executed computationally, where cover works, for example, text records, pictures, sound documents, and video documents are changed so that a mysterious message can be inserted inside them. In this paper JSteg and JMQT techniques and their encoding and deciphering calculation has been talked about exhaustively. Besides , exhibitions grids for steganography has been talked about exhaustively. An examination is made between three boundaries namely, PSNR, Capacity and stego Size utilizing two steganography strategy to be specific; JSteg and JMQT has been made. The test results reason that utilizing the shading part method for shading picture steganography JMQT gives great PSNR and limit when contrasted with JSteg and JSteg gives great stego size proportion results as contrast with JMQT. In segment first we need to examine about presentation
