A new algorithm to secure image steganographic file

摘要

In this digital world, steganography is intended to protect information from intruder, attacker and unwanted parties. Steganography is an excellent means by which security can be accomplished in transferring data over the network but it can be detected by bits comparison tools available in the market. In this paper, a new Algorithm to Secure Steganographic File is proposed which is undetectable by bits comparison tool and any other method. By this algorithm, we use those bits of image RGB (Red, Green, Blue) LSB (Least significant Bit) values which are same as the value of message to be hidden. It implies that those bits of image are remembered which are same as bit of message to be encrypted. Images are send in the starting by physical means after that image number and formula (which is to be applied on that image) is transferred online in hash form. This process makes the communication hundred percent secure.
