The Internet is global in scope and rapidly growing. With this growth, internet security threats are also increasing. The Internet is the global information exchange media, which is open and insecure, needs more and better security provision. In the era of computer network virtually all business, government and academic organizations interconnect their local area network with a collection of interconnected networks. Data transmission in a public communication system is not secure because of interception and improper manipulation by an opponent Therefore, the attractive solution for this problem is steganography, which is the art and science of writing concealed messages in such a way that no one, apart from the sender and intend recipient, can notice the existence of the message. Thus, confidentiality and integrity principle of security can be achieved. There have been wide ranges of algorithms introduced using a text file as cover media. This thesis explains a two layered hiding technique that provides high security than other techniques. The use of local language ensures more security to the information exchange as the awareness of the local language is limited. The proposed approach uses the local language Punjabi as cover text. In proposed approach, the cover media is pre-existing media, not system generated media. Therefore, a user will be free to use the cover media taken from any Punjabi newspaper, magazine or book and the syntax of a sentence and sequence of sentence both will be true grammatically. Even though the opponent has a very good command on the Punjabi language, they will not found any suspicious.
