A REVIEW OF IMAGE STEGANOGRAPHY TECHNIQUES: DEVELOPMENT TRENDS TO ENHANCE PERFORMANCE

Abstract

Steganography deals with the study of invisible information. It is the art and science of hiding the existence of message being sent so that except sender and receiver no one knows about the sent message. Secret message is hidden inside mediums like text, images, network and protocol. These are used as carrier to hide the secret message without any significant change in the carrier which is visible to human eye. This doesn’t cause any suspicion about the secret message. This paper presents the review of different security and data hiding techniques available that are used to implement the image steganography.
