Secure data transmission over the unsecured internet is an important aspect in communication. In recent times, data piracy, unauthorized access, loss of crucial information has been one of the important concern in secure communication of data. To provide security over data transmission, multiple techniques are provided each having its own benefits such as cryptography, steganography and watermarking. Cryptography is the technique for modification of data for secured transmission in an unreadable format. Steganography is the process of hiding the cover file with another file and transmitting the cover file without knowing the existence of hidden message. Watermarking is protection technique used to shield the information from intruders. Various combinations of cryptography and steganography is used to make data more secure. Such techniques differ in various aspects which are load capacity, security, efficiency, simplicity, and much more. Watermarking is the most used technique used for copyright protection in media files in recent times while cryptography and steganography are used to protect the data during communication so that the original data cannot be altered. In this paper, various techniques of cryptography and steganography are discussed which are used in the project.
