In the recent trend steganography plays an important role in providing secrecy in internet. Steganography works by replacing bits of useless or unused data in regular computer files with bits of different, invisible information. Cryptography is used to scramble the information sent and make it as a scrambled text which is not understandable. Steganography is used to hide the information so that secrecy can be established. If Steganography and Cryptography are used together it has more advantage for providing security for the information. In this paper hiding of data in digital images formation carried out using adaptive hiding with the optimum pixel adjustment (OPA) algorithm. Resultant system evidences remarkable hiding rates with other Steganographic systems.Keywords
