A method and apparatus for applying steganography to digital image files are provided. This algorithm uses the basic idea of steganography. In one aspect of the invention a method is provided. The method comprises (a) taking a text message as input, (b) breaking up the input data into a series of bits, and (c) passing it to an encryption mechanism to merge into a bit map image. Thus, less important information from a bit map image is removed and hidden data (series of bits) is injected in its place. It is thus possible to (a) retrieve the entire bit map file, (b) remove its header information, (c) retrieve each byte one by one and (d) put the input data in each byte.
