Hiding multiple Text pages into a Color image

This program can encode/decode maximum of six monochrome Text pages into a Color image without loss.

Description

This program has the ability to embed/hide multiple text images into any color image. The encoded text images can be seamlessly recoverable without any loss. The key advantage in this coding algorithm is the embedded text image does not create any visible patterns on the color image. Thus no one can identify the hidden text by sight. This ensures secure way of transferring confidential data through the widely available picture images as a data carrier. This method can be utilized in web pages, e-mail and media.
Note: Estimated execution time measured on a Pentium 4 (2.66 GHz) series processor is: 31 sec 953 millisec (Image resolution 800 x 600)

• Required Products: Image Processing Toolbox
• MATLAB release: MATLAB 7.0.1 (R14SP1)

Unfortunately any slight change applied to the watermarked image will destroy the hidden information, since the information is hidden in the LSB, which is the most vulnerable bit to changes.
This works only in case the images are exchanged via completely lossless means.
