RSA Secured Web Based Steganography Employing HTML Space Codes And Compression Technique

Web development has given its way to develop the strategies to secure the information available on the web. The data can be secured in numerous ways and one of the common way is to obnubilate the data through HTML web pages where the data is hidden in the source code of the web document. The web contains innumerable amount of personal data which needs to be hidden. We propose an algorithm which combines the techniques of cryptography and steganography which aids in securing the data by hiding it behind the source code of the HTML web pages. RSA encryption is used for encrypting the secret message. The encrypted data is compressed, mapped into Space codes and embedded under the HTML web pages by making mere changes in the code which cannot be noticed by the intruder as they are not suspicious. The robustness and security are enhanced.
