Steganomark: Embedding XML Data in a Color Image

A novel scheme for the embedding XML file in a 24-bit BMP color image using steganographic technique is presented in this paper. The lab color space is used instead of the RGB color space which is found to be more suitable for watermarking application. The XML file that is to be embedded is encrypted by providing a password and decrypted during watermark detection phase. The watermark detection process is fast and the embedded XML file is extracted from the watermarked color image which neither requires the original image nor the embedded XML file. Using this application user can easily watermark the image and hide the XML file in to the image. The usage of lab technique has the advantage that the watermarked image file is imperceptible to human eye.
