An Overview of Image Steganography: Survey and Analysis

Abstract

Steganography is the specialty of concealing information in cover medium and the cover medium could be pictures, sound or video record. Any critical information could be covered up inside a computerized transporter picture. Steganography gives preferred administrations over cryptography. Reason is that cryptography conceals the substance of the message yet not the presence of the message. So nobody separated from the approved sender and beneficiary will know about the presence of the mystery information. Steganographic messages are frequently first encoded by some conventional means and afterward a cover picture is adjusted somehow to contain the scrambled message. The recognition of steganographically encoded bundles is called steganalysis.
