Data Security and Authentication Using Steganography

Steganography is the art of covered, or hidden, writing. The purpose of steganography is covert communication to hide the existence of a message from a third party. This proposed system deals with implementing security-using Steganography. In this technology, the end user identifies an image which is going to act as the carrier of data. The data file is encrypted and authenticated. This message is hidden in the image. The image if hacked or interpreted by a third party user will open up in any image previewer but not displaying the data. This protects the data from being invisible and hence be secure during transmission. The user in the receiving end uses another piece of code to retrieve the data from the image.
