This paper addresses an digital image forensic marking scheme against D/A-A/D conversion such as print-to-capture model performed by a photo printer and digital camera. When capturing a printout image by a digital camera, various kinds of distortions such as compress, noise, geometrical distortions, and lens distortions are applied slightly and simultaneously. In this paper, we consider several steps to extract forensic mark from the D/A-A/D distorted image in print-to-capture scenario. To embed 64-bits customer ID into an image and in order to extract forensic mark from a captured image, a multi-bits forensic mark is embedded repeatedly like a tiling pattern. We show that the extracting is successful from the image captured by a digital camera through the experiment.
