Data Security by Preprocessing the Text with Secret Hiding

With the advent of the Internet, an open forum, the massive increase in the data travel across networkmake an issue for secure transmission. Cryptography is the term that involves many encryption method to make data secure. But the transmission of the secure data is an intricate task. Steganography here comes with effect of transmission without revealing the secure data. The research paper provide the mechanism which enhance the security of data by using a crypto+stegano combination to increase the security level without knowing the fact that some secret data is sharing across networks. In the firstphase data is encrypted by manipulating the text using the ASCII codes and some random generated strings for the codes by taking some parameters. Steganography related to cryptography forms the basisfor many data hiding techniques. The data is encrypted using a proposed approach and then hide the message in random N images with the help of perfect hashing scheme which increase the security of the message before sending across the medium. Thus the sending and receiving of message will be safe and secure with an increased confidentiality.
