Performance Enhancement of a Steganographic Technique in Information Hiding

Steganography is the art of inconspicuously hiding data within data.Steganograhy goal in general is to hide data well enough so that unintended recipients do not suspect the Steganographic medium of containing hidden data. As privacy concern to develop along with the digital communication domain, steganography will undoubtedly play a growing role in the society. For this reason, it is important that we are aware of steganography technique and its implications. This paper shows a combining technique of using DCT and Neural Network together so that a large amount of data can be store inside the image showing invisibility to the users and also enhances the level of security.
