Abstract— Steganography is a technique of hiding the secret information. Steganography hides the existence of the secret data and make the communication undetectable. Secret data can be communicated in an appropriate multimedia carrier such as image, audio or video. Image steganography is extensively used technique. In this technique secret data is embedded within the image. Steganography techniques can be categorized into two groups - adaptive and non-adaptive. Each of these have its strengths and weaknesses. Adaptive steganography embeds the secret information in the image by adapting some of the local features of the image. Non-adaptive steganography embeds secret data equally in each and every pixel of the image. Several techniques have been proposed for hiding the…show more content…
Still, message transmissions over the Internet need to face a few issues, for example, copyright control, information security, and so on. Consequently we need secure secret specialized strategies for transmitting message over the Internet. Encryption is a surely understood strategy for security insurance, which alludes to the process of encoding secret data in such an approach, that just the person with the right key can effectively decode it. In any case, encryption makes the message unreadable, and making message sufficiently suspicious to pull eavesdroppers’ consideration. Another approach to tackle this issue is to conceal the mystery data behind a cover with the goal that it draws no extraordinary consideration. This strategy of data security is called steganography (Petitcolas and Anderson,1998; Petitcolas and Katzenbeisser, 2000) in which imperceptible communication happen. The cover could be a digital picture and the cover image after embedding is called stego-picture. Attackers don't have the foggiest idea about that the stego-image has concealed mystery information, so they won't mean to get the mystery information from the
