DIGITAL WATERMARKING IMAGE SIGNALS ON-CHIP AND PHOTOGRAPHIC TRAVEL LOGS THROUGH DIGITAL WATERMARKING

摘要

The disclosure describes methods and apparatus for providing digital watermarks or steganographic indicia in image or video data. One implementation embeds digital watermarks on-chip with respect to a CMOS or CCD image array. Some implementations introduce a watermark component during image capture, the watermark being introduced through variations in physical characteristics of a set of pixels. Other implementations are provided and claimed as well.
