Abstract
Abstract Frames of video and image data are processed to convey plural bits of hidden auxiliary data. The auxiliary data can be used for identification purposes, for device control (disabling video recording and the like), etc. The claimed arrangement uses a data embedding technique wherein the value of single pixels of the video or image data are influenced by the values of several of the bits of auxiliary data. A great variety of other techniques and applications are also detailed.

Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
75 words
In a method of processing video to hide N-bits of embedded information in video data corresponding to visible portions of plural frames thereof, N being at least two, and thereafter producing a pixelated representation of said processed video data on a display screen, each pixel having a luminance value, an improvement wherein each of plural of said pixels has a luminance value that is a function of plural bits of said N-bits of embedded information.
Claim 2
Dependent Claim
75 words
In a method of processing video to hide N-bits of embedded information in video data corresponding to visible portions of plural frames thereof, N being at least two, and thereafter producing a pixelated representation of said processed video data on a display screen, each pixel having a luminance value, an improvement wherein each of plural of said pixels has a luminance value that is a function of plural bits of said N-bits of embedded information.
