<p>The objective of this work is to develop a hardware-based watermarking system to identify the device using which the photograph was taken. The watermark chip will be fit in any electronic component that acquires the images, which are then watermarked in real time while capturing along with separate key. Watermarking is the process of embedding the watermark, in which a watermark is inserted in to a host image while extracting the watermark the watermark is pulled out of the image.</p>
