The digital communication has become an essential part of our daily life, a lot of applications are Internet-based and it is important that communication be made secret. We know cryptography and steganography are two methods used for data protection. The cryptography distorts the data and steganography hides the existence of data. But both of them have their own vulnerabilities, in this paper we are focused to combine cryptography and steganography in various ways to enhance the security of data.
