Abstract: Information security is major concern now a days as number of users using internet are increasing and information getting shared every second. This has also increased the cyber-crime and threat for the information being shared. Two important techniques being used for information security are steganography and cryptography. Encoding the secret test into another form is called Cryptography and it is basically secret writing; on the other side Steganography is hiding a data. In this article, a hybrid technique is introduced by combining the cryptography, compression and Steganography properties. This proposed algorithm works on spatial domain, which also use the space efficiently.
Keywords:Steganography, Cover image, Encryption,compression.
