Abstract: Cryptography is an art of making the data unintelligible to third party other than the sender and receiver. The security for data can be implemented using public and private cryptography. The data is made secure using many data encryption techniques. We have proposed an advanced technique of encryption involving unique VPASS Algorithm. Original work related this includes the playfair technique and since then modification to this have been proposed. Our scheme involves the use of unique VPASS matrix to encrypt the messages. Security of the message can be enhanced by using a steganography technique. Steganography is the art of concealing the existence of information within seemingly harmless carriers. In this paper we have proposed a revised information hiding scheme using VPASS technique. Original work related to our scheme includes the Chang et al method of information hiding. The Chang et al method can be implemented for greyscale images but our method can be implemented for colour images.
