Abstract

A method and apparatus for providing and determining integrity of video is provided herein. During operation, a trusted unit such as a computer housed within a securable trunk of a vehicle generates or receives data on stimuli applied to a camera and receives video purportedly taken by that camera, as means for the trusted unit or an independent entity to determine if time periods of the stimuli correspond to responses seen or heard within the video.

Claims

1. A method for determining the integrity of video, the method comprising the steps of:

instructing an external apparatus to produce and apply stimuli to a camera while a video is being recorded by the camera, wherein the external apparatus is a light or a camera mounting;

recording time periods during which the stimuli is applied;

receiving the video recorded by the camera;

receiving data on stimuli applied to the camera;

determining if time periods during which the stimuli is applied correspond to a response seen within the video; and

determining the integrity of the video based on whether time periods during which the stimuli is applied correspond to responses seen within the video.

2. The method of claim 1 wherein the stimuli are generated or produced externally to the camera.

3. The method of claim 1 wherein the stimuli comprises of a zoom, bump, turn, position, or an acceleration of the camera.

4. The method of claim 1 wherein the step of determining the integrity comprises the step of determining the video has not been altered in any way since it was created by the camera and that the video has not been counterfeited.

18. The method of claim 1, wherein the external apparatus and camera are mounted to a vehicle, and instructing further comprises sending instructions by a computer, also mounted to the vehicle, to the external apparatus.

19. The method of claim 18, wherein when the external apparatus comprises a light, the light comprises a rooftop light-bar mounted to the vehicle, and roof-top light bar receiving instructions from the computer to apply stimuli to the camera.

20. The method of claim 18, wherein when the external apparatus comprises a camera mounting, the camera mounting is mounted to the vehicle and receives instructions from the computer to apply stimuli to the camera.

21. The method of claim 20, wherein the instructions comprise instructions for the camera mounting to move in particular directions or to acquire certain positions.

5. A method for providing integrity of video, the method comprising the steps of:

recording video with a camera;

instructing an external apparatus to produce and apply stimuli to the camera while the video is being recorded, wherein the external apparatus is a light or a camera mounting;

separately recording stimuli applied to the camera and further recording the time periods during which the stimuli is applied; and

storing both the recorded video and the recorded stimuli so that the integrity of the video can be insured by determining if time periods during which the stimuli is applied correspond to a response seen within the video.

6. The method of claim 5 wherein the step of separately recording stimuli comprises the step of recording the stimuli via an accelerometer.

7. The method of claim 5 wherein the stimuli comprises of a zoom, bump, turn, position, or an acceleration of the camera.

10. The apparatus of claim 7 wherein the stimuli comprises of a zoom, bump, turn, position, or an acceleration of the camera.

16. The method of claim 5, wherein the instructions are sent by a computer mounted to a vehicle, and the external apparatus and camera are also mounted to the vehicle.

17. The apparatus of claim 16, wherein when the external device comprises a light, the light comprises a rooftop light-bar mounted to the vehicle, the roof-top light bar receiving the instructions from the computer to apply the stimuli to the camera;

and wherein when the external device comprises a camera mount, the camera mount receiving the instructions from the computer to apply the stimuli to the camera.

8. An apparatus for determining the integrity of video, the apparatus comprising:

a computer receiving a video recorded by a camera, receiving data on stimuli applied to the camera, wherein the stimuli is created by an external device, the external device receiving instructions from the computer to produce and apply the stimuli while the video is being recorded, further wherein the external device is a light or a camera mounting, recording time periods during which the stimuli is applied, determining if time periods during which the stimuli is applied correspond to a response seen within the video, and determining the integrity of the video based on whether time periods during which the stimuli is applied correspond to responses seen within the video.

9. The apparatus of claim 8 wherein the stimuli are generated or produced externally to the camera.

11. The apparatus of claim 8 wherein the step of determining the integrity comprises the step of determining the video has not been altered in any way since it was created by the camera and that the video has not been counterfeited.

12. The apparatus of claim 8, wherein the computer, the external device and the camera are mounted to a vehicle.

13. The apparatus of claim 12, wherein when the external device comprises a light, the light comprises a roof-top light bar of the vehicle, the roof-top light bar receiving the instructions from the computer.

14. The apparatus of claim 12, wherein when the external device comprises a camera mount, the camera mount receives the instructions from the computer.

15. The apparatus of claim 14, further comprising a plurality of cameras each mounted to the vehicle via a camera mount, the plurality of cameras positioned to view other cameras and the movements of their respective camera mounts.
