简介
Cameras are more and more common in mobile phones and this creates new opportunities and threats to digital watermarking. We discuss about the difficulties that occur while reading a watermark with a digital camera or a camera phone and what kind of applications and technical solutions have already been invented. Not much research has been done on this field but commercial applications have already showed the potential demand for print-cam robust watermarking methods.
