A NEW STEGANOGRAPHY METHOD BASED ON HIOP (HIGHER INTENSITY OF PIXEL) ALGORITHM AND STRASSEN'S MATRIX MULTIPLICATION
As the communication increases day by day the value for security over network alsoincreases. There are many ways to hide information or transmission of information secretlyIn this sense steganography is the best part of sending information secretly. Steganography in the last few years has gained a wider audience. The technology has certainly been the topic of widespread discussion among the IT community. This 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. For hiding secret information in images, there exist a large variety of steganography techniques some are more complex than others and all of them have respective strong and weak points. The out come of thispaper is to generate a cross platformthat can effectively hide a message inside a digitalimage file. We select pixels with the HIOP (Higher Intensity Of Pixel) algorithm. We divide the image into blocks and determine higher Intensity color Of pixel in each block and use astrassen multiplication in each blockwe create more dispersion in a selected pixels. As a result, the security level increased in hide of dataand also in discover of cipher text. It is also, try not to degrade image quality and as far as possible does not change the image size.
