Information hiding in internet webpages

Abstract

A new data hiding technique was used in an HTML Webpage since HTML tags are case insensitive. And if we change the letter case in HTML tags, there is no visible distortion to the browser. We make good use of this redundancy to embed the secret message. And the message can be extracted by viewing source code. However, this data hiding algorithm is very easy to detect the message. In order to enhance the security, baker map and linear feedback shift register (LFSR) were used to encrypt the data before embedding into HTML Webpages. In my final year project (FYP), secret message was successfully embed into HTML Webpages, and the baker map and LFSR were used to encrypt the message successfully. I also found out some solutions to improve the algorithm, e.g. increase the capacity of the Webpages. The C programming language was used to build the algorithm. A graphic interface was designed with using C++. In the final stage of FYP, I tested the program, tried to spot the error as well as evaluated the program by measuring its process time and checking its security. At the end of the project report, there is a discussion regarding the novel algorithm and some recommendations of future works were given in the discussion part too.
