Fast evaluation of digital data exchange occurs in recent years. Due to that security of information is much important in data storage and transmission process. Security of internet banking account passwords, email accounts password etc. requires text protection in digital media. In the same way image transmission and storage during industrial and research processes requires image protection. The National Institute of Standards and Technology (NIST) have initiated a process to develop Federal Information Processing Standard (FIPS) which should be most flexible, secure, fast and which can replace data encryption standard.
