Abstract
Method and apparatus are disclosed for publishing locational copyrighted watermarking video. According to some embodiments, a method for embedding location information into a video comprises: separating the video into at least one key frame and at least one in-between frame set corresponding to the at least one key frame; receiving location data for the at least one key frame; encrypting the location data for the at least one key frame based on a location private key; and embedding the encrypted location data into the at least one key frame.

1-50. (Cancelled)
An apparatus for embedding location information into a video, the apparatus comprising:
- at least one processor;
- and
- at least one memory including computer-executable code,
- wherein the at least one memory and the computer-executable code are configured to, with the at least one processor, cause the apparatus to:
- separate the video into at least one key frame and at least one in-between frame set corresponding to the at least one key frame;
- receive location data for the at least one key frame;
- encrypt the location data for the at least one key frame based on a location private key;
- and
- embed the encrypted location data into the at least one key frame.
An apparatus for extracting location information from a video, the apparatus comprising:
- at least one processor;
- and
- at least one memory including computer-executable code,
- wherein the at least one memory and the computer-executable code are configured to, with the at least one processor, cause the apparatus to:
- separate the video into at least one key frame and at least one in-between frame set corresponding to the at least one key frame;
- extract encrypted location data from the at least one key frame;
- and
- decrypt the encrypted location data based on a location public key.
An apparatus for hiding at least first and second copyright watermark data into a video, the apparatus comprising:
- at least one processor;
- and
- at least one memory including computer-executable code,
- wherein the at least one memory and the computer-executable code are configured to, with the at least one processor, cause the apparatus to:
- separate the video into at least one key frame and at least one in-between frame set corresponding to the at least one key frame;
- and
- merge the at least first and second copyright watermark data into the at least one key frame.
An apparatus for decoding a copyright watermark data from a video, the apparatus comprising:
- at least one processor;
- and
- at least one memory including computer-executable code,
- wherein the at least one memory and the computer-executable code are configured to, with the at least one processor, cause the apparatus to:
- separate the video into at least one key frame and at least one in-between frame set corresponding to the at least one key frame;
- read a data structure from the at least one key frame, the data structure having stored therein at least first and second copyright watermark data;
- and
- decode the first or second copyright watermark data according to a property of the data structure.
