A Review Paper on Digital Image Steganography Techniques
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2017, Vol 5, Issue 5
Abstract
Steganography means covered writing or secret writing. For this secret writing different steganography techniques have been developed. Encryption of secret information is possible and this encrypted information can be hidden behind the original cover file. The main aim of steganography technique is to hide secret data behind image, because image is the basic form of transmitting information in the visual format. In steganography technique the original message is encrypted also stego key is used for protection and this message is hidden into the original image. Privacy, security and protection are three main aspect of secret data communication. The various steganography techniques are compared in this paper and taken review for the secret data communication. Mainly this paper is used to provide background to image steganography methods. It includes properties, applications and analysis of different techniques for development of new steganography technique for images.
