Embedding geo-location information in media
First Claim
1. A method comprising:
- receiving digital data representing media comprising at least video and audio;
digital watermarking at least some portions of the digital data, wherein the digital watermarking introduces changes to at least some portions of the digital data to hide information in at least some portions of the digital data representing audio and in at least some portions of the digital data representing video, wherein the information comprises at least geo-location data and time data, wherein the geo-location data is redundantly hidden in digital data over time, and wherein the geo-location data comprises an index to access a data repository to obtain information regarding a location associated with optical projection of the media; and
optically projecting the media on a surface for viewing, wherein the projected media includes the information digital watermarked therein.
