A Survey Paper on Steganography and Cryptography

Steganography is the art of hiding the fact that communication is taking place, by hiding information in other information. The digital images are the most popular because of their frequency on the Web among all different carrier file
formats. Image steganography, achieves the secrecy by embedding data into cover image and generating a stego-image. There are many types of steganography techniques each have their advantages and disadvantages. This paper intends to give an overview of image steganography, cryptography, its uses and techniques. It also attempts to identify and briefly reflects on
which steganographic techniques are more suitable for which applications.
