Method and apparatus for secure transport and storage of surveillance video
View Patent ↗Security information such as fixed or dynamically received camera location information, laser signature information, timestamp information, and network information, may be used to secure the transport and storage of surveillance video. Where the surveillance video is to be transported on a communication network, the round trip time from a video data storage server to the surveillance camera and back to the video data storage server may be monitored and periodically added to the secured video data. By checking to see whether the round trip time has changed, it may be possible to determine whether the video has been tampered with. The secured video data may also be transported over two or more paths on the network to two or more video data storage servers so that redundant copies may be stored at different primary locations. By comparing copies of the data, alteration of one of the copies may be detected.
1. A method of securing video information, comprising:
capturing the video information, comprising image information and security information, at a first location;
transmitting, over at least two distinct transmission paths, at least two copies of the captured video information to at least one other location;
storing, on at least two distinct storage devices, the at least two copies of the captured video information at the at least one other location; and
comparing the at least two stored copies of the captured video information to detect tampering of the captured video information.
2. The method of claim 1 , wherein transmitting the at least two copies of the captured video information comprises multicasting the captured video information to the at least one other location.
3. The method of claim 1 , wherein transmitting the at least two copies of the captured video information comprises transmitting the at least two copies of the captured video information to at least two distinct locations.
4. The method of claim 1 , wherein comparing the at least two stored copies of the captured video information comprises comparing the at least two stored copies of the captured video information to determine whether the at least two stored copies of the captured video information are substantially the same.
5. The method of claim 1 , wherein the security information comprises time stamp information.
6. The method of claim 1 , wherein the captured video information comprises a locally generated video signature.
7. The method of claim 1 , wherein the image information comprises a locally generated video signature.
8. The method of claim 7 , further comprising locally generating the video signature using a light source.
9. The method of claim 8 , wherein locally generating the video signature using the light source comprises using a light source emitting light not visible to a human eye to locally generate the video signature.
10. A method of securing data, comprising:
transmitting, over at least two distinct transmission paths, at least two copies of the data, comprising first data and security data, to at least one other location;
storing, on at least two distinct storage devices, the at least two copies of the data at the at least one other location; and
comparing the at least two stored copies of the data to detect tampering with the data during transmission of the data.
11. The method of claim 10 , wherein transmitting the at least two copies of the data comprises multicasting the data to the at least one other location.
12. The method of claim 10 , wherein transmitting the at least two copies of the data comprises transmitting the at least two copies of the data to at least two distinct locations.
13. The method of claim 10 , wherein comparing the at least two copies of the data comprises comparing the at least two copies of the data to determine whether the at least two copies of the data are substantially the same.
