Abstract

At a high level, embodiments of the invention relate to augmenting video data with presence data derived from one or more proximity tags. More specifically, embodiments of the invention generate forensically authenticated recordings linking video imagery to the presence of specific objects in or near the recording. One embodiment of the invention includes video recording system comprising a camera, a wireless proximity tag reader, a storage memory and control circuitry operable to receive image data from the camera receive a proximity tag identifier identifying a proximity tag from the proximity tag reader, and store an encoded frame containing the image data and the proximity tag identity in the storage memory.

Claims

1. A video recording system comprising:

a camera;

a wireless proximity tag reader;

a non-audiovisual sensor;

a storage memory; and

control circuitry operable to;

receive image data from the camera;

receive, from the proximity tag reader, a proximity tag identifier identifying a proximity tag associated with one of a user'"'"'s badge, a user'"'"'s proximity card, and a user'"'"'s weapon, wherein the proximity tag identifier allows the image data to be associated with the user;

receive, from the non-audiovisual sensor, sensor data; and

store an encoded frame containing the image data, the proximity tag identifier, and the sensor data in the storage memory.

2. The system of claim 1, wherein the proximity tag reader is an RFID reader.

3. The system of claim 1, wherein the control circuitry is further operable to:

receive a plurality of proximity tag identifiers; and

store each of the received plurality of proximity tag identities in the encoded frame.

4. The system of claim 3, wherein a first proximity tag identifier of the plurality of proximity tag identifiers is associated with a person and a second proximity tag identifier of the plurality of proximity tag identifiers is associated with an object.

5. The system of claim 1, wherein the control circuitry is further operable to generate a digital signature for the encoded frame.

6. The system of claim 5, wherein the digital signature is generated using a device-specific key.

7. The system of claim 1, wherein the image data comprises video data.

8. The system of claim 1, further comprising a second camera providing image data to the control circuitry.

9. The system of claim 1, wherein the control circuitry is further configured to store data relating to the distance of the proximity tag from the proximity tag reader.

10. A method of recording authenticated video with presence data, comprising the steps of:

creating an augmented encoded frame by;

encoding video data into an encoded frame;

receiving one or more proximity tag identifiers from a proximity tag reader; and

including the received proximity tag identifiers as metadata for the encoded frame to produce the augmented encoded frame;

generating a digital signature for the augmented encoded frame; and

storing the augmented encoded frame and digital signature.

11. The method of claim 10, wherein the proximity tag reader is an RFID reader.

12. The method of claim 10, further comprising the step of creating an additional plurality of augmented encoded frames of data by repeating the steps of creating an augmented encoded frame, generating a digital signature, and storing the augmented encoded frame and digital signature a plurality of times for additional video data.

13. The method of claim 12, further comprising the step of creating a video stream from the plurality of augmented encoded frames.

14. The method of claim 13, wherein the video stream further includes a plurality of non-augmented encoded frames.

15. A computer-readable medium storing an augmented video file, said video file comprising:

a plurality of augmented frames, each augmented frame of the plurality of augmented frames including video data and one or more identifiers each associated with a respective proximity tag.

16. The computer-readable media of claim 15, wherein the video file further comprises a plurality of non-augmented frames.

17. The computer-readable medium of claim 15, further storing a digital signature corresponding to at least one augmented frame or non-augmented frame.

18. The computer-readable medium of claim 15, wherein the computer-readable medium is tamper-resistant.

19. The computer-readable medium of claim 15, further storing data from a non-audiovisual sensor associated with the video file.

20. The computer-readable medium of claim 15, wherein the computer-readable medium stores augmented video frames including video data from a plurality of cameras.
