On the Differences between Hiding Information and Cryptography Techniques: An Overview
The growing possibilities of modern communications need the special means of security especially on computer network. The network security is becoming more important as the number of data being exchanged on the Internet increases. Therefore, the confidentiality and data integrity are requires to protect against unauthorized access and use. This has resulted in an explosive growth of the field of information hiding. Nowadays, protection system can be classified into more specific as hiding information (Steganography) or encryption information (Cryptography) or a combination between them. In this study, we have review the strength of the combine the steganography and cryptography techniques, since there is non-existence of standard algorithms to be used in (hiding and encryption) secret messages. As a result of this study, the two techniques have been presented and the combination between these techniques has been discussed.
