摘要：In this paper we survey different steganography techniques for encrypting the data. Steganography is a technique that allows the one to hide the data within an image while adding few noticeable changes. This paper discusses the concept behind the steganography by exploring firstly what is the steganography and the terms that are related to steganography. This paper explores the steganography methods ¨C image steganography, audio steganography, video steganography, text steganography that are used to embed the information in digital carriers. The two most important aspects of image based stegnography system are the quality of stego image and the capacity of the cover image. By reviewing this paper, researchers can develop a better steganography technique to increase the MHC and PSNR value by analyzing the existing steganalysis techniques
