Data hiding in color image using cryptography with help of ASK algorithm

There are many security issues in data communication. Cryptography is a substantially safe method to provide protection in data receiving and sending. This paper also expresses a novel algorithm of data hiding using cryptography named as ASK algorithm. Sensitive data is hided in a colour image using cryptography. This paper shows how data can be send using a colour image without ignorance of third party. Algorithm describes a method for vanishing data in a colour image.
