Abstract

In this paper, an approach to transfer data securely is proposed. First, from the sender side, the data is encrypted using Rivest-Shamir-Adleman (RSA) algorithm and then this encrypted data is hidden using Least Significant Bit image steganography concept in a image of the web page and its url is sent to the receiver. Then, at the receiving end, the encrypted data is obtained that is hidden in the image of the web page whose url is sent. This encrypted data is decrypted using the same RSA algorithm . When the sender sends the data to the receiver and incase this data is obtained by the third person or an intruder he will see a URL being sent. Then he will open the URL and he will find a webpage, and he would not find any data being hidden. Then he will try to view the source code of the webpage, and then also he would not find any data being hidden. Thus, the intruder will be assured that no data is been hidden in this and chances are more that he would not go to decode it further. Hence, the chances of doubt an intruder can get that some confidential or private data is hidden in the data being sent is reduced. And hence, the data sent by the sender to the receiver is secured.
