In the community of information technology users often occur several crimes either consciously or unconsciously, intentionally or unintentionally done. Way to secure data in the form of digital images can use cryptographic technique; cryptography is one of the techniques used to enhance the security aspect of information. Cryptography is the study of science and art to keep a message or data information so that the data is safe. Cryptographic support the needs of the two aspects of information security, namely secrecy (protection of the confidentiality of data information) and authenticity (protection against counterfeiting and alteration of information that is undesirable).Along with the development of computer technology, the world of information technology requires a stronger cryptographic algorithm and secure. Currently, AES / Rijndael (Advanced Encryption Standard) is used as the newest standard cryptographic algorithms. AES / Rijndael replace the DES (Data Encryption Standard), which in 2002 was over its service life.
