Security of the secret information has been a challenge when the large amount of data is exchanged on the internet. A secure transfer of information can be very much achieved by steganography and Cryptography. Steganography is a tool for hiding information inside an image. Cryptography is a tool which provides encryption techniques for secure communication. This paper presents a survey on various steganograpgy techniques along with other techniques used in the literature from 2003-2013. Several different techniques are mentioned with their benefits, limitations, year of publication and their authors. 65 papers were selected after content filtering out of more than 150 papers. LSB (least significant bits) technique was mostly used, while MSB (most significant bits) technique was very less used. There were also several other techniques used such as SSHDT, RSTEG, DCT, DWT, LWT etc... in various papers. Combined techniques of steganography and cryptography were also used in some papers. The survey results show that the steganogarph has played a very beneficial role in various applications. It increased the level of information security with a wide use of its techniques. It would be very useful and provide a better platform for the beginners who want to work in steganography. By analyzing the existing techniques more new techniques can be developed.
