A High Security Approach For Image Steganography By Rapid Information Retrieval
Khosravi Sara, Mashallah Abbasi Dezfouli · International Journal of Advanced Research in Computer Science · 2011
There are many ways to hide information or transmission of information secretly. In this sense steganography is the best part of sending information secretly. The technology has certainly been the topic of widespread discussion among the IT community. Steganography, like watermarking and fingerprinting is a branch of science to hide information but, unlike watermarking and fingerprinting, steganogaraphy is the art ofwriting message or information in such a way that no one apart suitable recipient knows the meaning of the message or information. There are many techniques to performsteganography on electronic media, most notably audio and image files. The out come of thispaper is to generate a cross platformthat can effectively hide a message inside a digitalimage file. We are presenting a technique which works by changing a few pixel color value at selected pixel in the image. We divide the image into blocks and in each block, To increase the security level, we create distribution in selected pixels whit using strassen multiplication in each block. Also, when retrieving a message for avoid repeating process which hidden text storage and speed up information retrieval, we save address of selected pixel. It is also, try not to degrade image quality and as far as possible does not change the image size. Key words: Steganography, watermarking, fingerprinting, strassen multiplication
