Abstract

Steganography is the science of hiding information in a multimedia carrier such as an image, audio or video file. The method used to hide information prevents attackers from revealing it and sharing it with others. Digital images such as bitmap files are the mostly used carriers for steganography. This paper presents a new technique that embeds secret message in the LSB of the cover image. In boosted steganography, the cover image is preprocessed before the message is embedded into the LSBs. The secret data is first converted into stream of bits and compared with the LSBs of cover image. The level of distortion is noted. The combination of brightness and contrast of the image is varied and then LSBs of cover image are compared with the secret data bit stream. The point at which distortion level is reduced to the minimum is determined. Finally the secret data is embedded in the image having a particular selected value of brightness and contrast. The experiment measures total number of matches and mismatches between LSB bits and secret data for different levels of brightness and contrast of the image. The results show improvement in the existing scheme of LSB embedding.
