Network Data Security Using Lsb Steganography

In the past few years, number of applications are developed to access multimedia systems and content over web. The security and integrity of information, has become one of the most needful problem for sharing secure information over web. Steganography is a means to achieve this task. In this paper, the hash function has been implemented and integrated into a secure package to protect multimedia information through the network. The hash function uses the LSB (Least Significant Bit) method. The algorithm has been tested with own made steganography application in the windows environment. It has been proved that extracting any information from embedded image is hard for any eavesdropper with computational resources.
