Embedding location data in video

A method to identify video, the video comprising video frames captured from an aerial platform, the aerial platform including at least one of a satellite, helicopter, unmanned aircraft, space shuttle and aircraft, an improvement comprising steganographically embedding data in the video, the data comprising first location data corresponding to at least a first location depicted in the video and second location data corresponding to at least a second location depicted in the video, the first location data differing from the second location data.

A method of steganographically marking video captured from an aerial platform, the video comprising at least a first video frame and a second video frame, the first video frame depicting a first terrestrial area having a first geo-location and the second video frame depicting a second terrestrial area having a second geo-location, said method comprises the steps of:

• providing a first steganographic signal in the first video frame, the first steganographic signal comprising first location data corresponding to at least the first geo-location;
• and
• providing a second steganographic signal in the second video frame, the second steganographic signal comprising at least a representation of a difference between the first geo-location and the second geo-location.

A method of digitally watermarking video comprising the steps of:

• digitally watermarking a first area in a first video frame to include a first payload associated with at least a ground coordinate of the first area;
• and
• digitally watermarking a second area in a second video frame to include a second payload that represents a difference between a ground coordinate of the second area and the first area ground coordinate.

A method of digitally watermarking a video sequence comprising the steps of:

• inserting a first digital watermark identifier at a first location within the video sequence, the first digital watermark identifier signaling that the first location corresponds with a predetermined geographical location;
• and
• inserting a plurality of digital watermark identifiers throughout the video sequence, wherein each of the plurality of digital watermark identifiers represents a change in geographical coordinates with respect to the first location.
