Transmission of data through internet has become very common now a day so, it is important to have secure communication over internet. Cryptography and Steganography are two important methods for providing secure communication. 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.
