Abstract:

Increase in the number of attacks recorded during electronic exchange of information between the source and intended destination as well as unauthorized usage of stored secret information has indeed called for a more robust method for securing data transfer and storage. Cryptography and steganography are the two popular methods available to provide security. One hides the existence of the message and the other distorts the message itself. In this paper, a data hiding system that is based on image steganography and cryptography is proposed to secure data transfer between the source and destination. Digital Image is used for the steganography and a LSB (Least Significant Bit) algorithm is employed to encode the message inside the image file. Two layers of encryption are applied to secrete data which provides multiple level of robust security recommended for the internet users for secure data transfer. Thus, in order to improve the security, the fusion of the two well known techniques called Crystography and their variation are proposed here.
