摘要：In this paper we will introduce what steganography is and what kind of applications can be expected. Steganography is an art and science of hidding information within other information. The word itself comes from Greek and means ‘hidden writing’. First complex book covering steganography was written by Johannes Trithemius in 1499. The book Steganographia itself was published later in 1606 and immediately placed on the Index Librorum Prohibitorum. In recent years cryptography become very popular science. As steganography has very close to cryptography and its applications, we can with advantage highlight the main differences. Cryptography is about concealing the content of the message. At the same time encrypted data package is itself evidence of the existence of valuable information. Steganography goes a step further and makes the Ciphertext invisible to unauthorized users.?
