s-Note allows encrypting note into an image leveraging on a mix of steganography and cryptography techniques. The encryption process requires the user to select its own password. Images that contain notes must not be modified: not resized or filtered in order to preserve the integrity of the note itself.

s-Note exploits the standard AES cryptography algorithm to encrypt user info and a modified version of the F5 steganography algorithm to inject them into an image.

s-Note Lite exhibits reduced functionality than s-Note.
