SilentEye is a cross-platform application design for an easy use of steganography, in this case hiding messages into pictures. It provides a nice interface and an easy integration of new Steganography algorithm and cryptography process by using a plug-ins system. The easiest way to open an picture is to drag and drop it on the main window of SilentEye. We can use it for classic system browsing as well and we can write our own plugins for better security. The application is available for Windows all versions and *nix systems.
