Abstract
A visual copyright protection system is disclosed, including input content, a disruption processor, and output content. The disruption processor inserts disruptive content to the input content creating output content that impedes the ability of optical recording devices to make useful copies of output content.
Claims18
A method for visual copyright protection comprising the steps of:
- (a) inputting content;
- (b) inputting light from a light source;
- (c) selecting a disruptive light modulating pattern based upon a criterion, said disruptive light modulating pattern configured to redistribute light temporally within a frame, said criterion being how said pattern is perceived by an IRD and a human differently, and said criterion further including selecting said pattern for the purpose of one of the following:
- (i) inserting a watermark;
- (ii) inserting a human perceivable image;
- (iii) inserting a non-human perceivable image;
- (iv) creating a disruption effect;
- and
- (v) creating disruption effects containing motion;
- (d) modulating a light array, having at least one element, using said inputted content and said disruptive light modulating pattern, said light array comprising a multitude of light arrays;
- (e) projecting said light onto said light array producing a modulated light beam;
- and
- (f) outputting said modulated light beam.
10 more elements
An apparatus for visual copyright protection comprising:
- (a) a light source capable of producing light;
- (b) a light array, having at least one element, capable of acting on said light to produce a modulated light beam;
- and
- (c) a disruption processor configured to modulate said light array using at least one disruptive light modulating pattern and inputted content, said disruption processor being a primary disruption processor and said primary disruption processor further including a multitude of supporting disruption processors, said at least one disruptive light modulating pattern selected using a criterion, said disruptive light modulating pattern configured to redistribute light temporally within a frame, said criterion being how said pattern is perceived by an IRD and a human differently, and said content is one of the following:
- (1) analog data;
- (2) digital data;
- and
- (3) a combination of digital and analog data.
