More About This Demo From The Author

Steganography is a cryptographic technique of security by obscurity. That is, only the sender and recipient know how to recover the hidden data. In this demo the secret data are text messages and they are hidden inside images. To the uninformed those images appear just like normal images but, for the recipient it is more than an image, it holds a secret information.

This demo application has been tested only on Firefox browsers (4+).
