Thumbnail steganography creates a thumbnail from a source image and stores data in it by altering it's color channels. To decipher the data, a new thumbnail is made from the original image and the differences between the pixels are calculated.
This project provides a simple Java-based steganography tool that can hide a message inside a 24-bit colour image so that knowing how it was embedded, or performing statistical analysis, does not make it any easier to find the concealed information.
