Many steganographic techniques [1,2, 3, 4] were proposed for hiding secret message inside images, the simplest of them being the LSB data hiding [6, 7, 8, 9, 10, 11]. In this paper, we suggest a novel data hiding technique in an Html Web page [12] and also propose some simple techniques to extend the embedding technique to source codes written in any programming language (both case insensitive like Html, pascal and case sensitive languages like C, C++, Java) - an extension to [12]. We basically try to exploit the case-redundancy in case-insensitive language, while we try hiding data with minimal changes int the source code (almost not raising suspicion). Html Tags are case insensitive and hence an alphabet in lowercase and one in uppercase present inside an Html Tag are interpreted in the same manner by the browser, i.e., change in case in an web page is imperceptible to the browser. We first exploit this redundancy and use it to embed secret data inside an web page, with no changes visible to the user of the web page, so that he can not even suspect about the data hiding. The embedded data can be recovered by viewing the source of the Html page. This technique can easily be extended to embed secret message inside any piece of source-code where the standard interpreter of that language is case-insensitive. For case-sensitive programming languages we do minimal changes in the source code (e.g., add an extra character in the token identified by the lexical analyser) without violating the lexical and syntactic notation for that language) and try to make the change almost imperceptible.
