Several methods in steganography and cryptography have been proposed for secured communication. But many compromises are there in them. Steganography which deals with security using multimedia has a very big disadvantage of increase in the information size. Cryptography which deals with encryption using the keys generated by various algorithms has the disadvantage of difficulty in remembering the key which can be easily cracked. The main objective of this paper is to increase the security in communication by encrypting the information with the key generated by using an image. This study proposes a novel algorithm for key generation using image features. It is a reliable and flexible method of key generation for information security.
