• abstract: The problem of authenticity for digital images has been helped by the development of digital watermarking. As an extension of the current state-of-the-art, a CMOS active pixel sensor (APS) imager with built-in watermarking of the output image is presented. A method for generation of watermarks specific to each chip is presented as well as simulations showing the effectiveness of the watermarking algorithm. The layout was designed in TSMC's 0.18 /spl mu/m 1.8/3.3 V process and circuit simulations indicate performance as expected.
