Abstract

A wearable video recording system with time-bracketed authentication is provided and includes a article, including a spine, wearable by a user, a recording device, supported on the spine, to generate a recording of a scene, an affecter subsystem, supported on the spine, to influence the scene being recorded with unpredictable data and an untrusted controller coupled to the recording device and the affecter subsystem, the untrusted controller being receptive of the unpredictable data, which the untrusted controller communicates to the affecter subsystem, and being configured to transmit at least hashed digests of the recording to one or more repositories.

Claims

1. A wearable video recording system with time-bracketed authentication, comprising:

an article, including a spine, wearable by a user;

a recording device, supported on the spine, to generate a recording of a scene;

an affecter subsystem, supported on the spine, to influence the scene being recorded with unpredictable data; and

an untrusted controller coupled to the recording device and the affecter subsystem,

the untrusted controller being receptive of the unpredictable data, which the untrusted controller communicates to the affecter subsystem, and being configured to transmit at least hashed digests of the recording to one or more repositories.

2. The wearable video recording system according to claim 1, wherein the spine comprises a headband.

3. The wearable video recording system according to claim 1, wherein the spine comprises headgear.

4. The wearable video recording system according to claim 1, wherein a source of the unpredictable data and a repository are co-located.

5. The wearable video recording system according to claim 1, wherein the untrusted controller is receptive of one stream of the unpredictable data from a single trusted challenge source.

6. The wearable video recording system according to claim 5, wherein the single trusted challenge source comprises a trusted hardware subsystem configured to:

generate the unpredictable data, and

interface with the untrusted controller.

7. The wearable video recording system according to claim 1, wherein the untrusted controller is receptive of more than one stream of unpredictable data from two or more somewhat trusted sources.

8. The wearable video recording system according to claim 7, wherein each somewhat trusted source comprises a geographically and administratively separate computing server that generates and stores a sequence of random data values and publicizes the random data values by broadcast or client service.

9. The wearable video recording system according to claim 7, wherein each somewhat trusted source publicizes:

identifying information,

a time-stamp,

a random stream of data and optionally a commitment thereto, and

authenticating information.

10. The wearable video recording system according to claim 1, wherein the one or more repositories are configured to:

maintain a local clock,

receive and store a repository message, including the at least hashed digests of the recording, and

time-stamp the repository message with a reception time thereof.

11. The wearable video recording system according to claim 1, further comprising a verifier configured to verify consistency of the recording with the at least hashed digests thereof.

12. The wearable video recording system according to claim 1, wherein the recording device comprises a camera to be worn on at least one or more of a head and a torso of the user, the camera comprising an optical filter.

13. The wearable video recording system according to claim 1, wherein the affecter subsystem comprises an illuminator to be worn on at least one or more of a head and a torso of the user.

14. The wearable video recording system according to claim 1, wherein the affecter subsystem comprises visible or near-infrared lasers including one or more lenses and diffraction screens.

15. The wearable video recording system according to claim 1, wherein the affecter subsystem comprises a user interface by which commands for influencing the scene and affecting the recording device, which are generated in accordance with the unpredictable data, are presented to the user.

16. The wearable video recording system according to claim 1, wherein the untrusted controller comprises a mobile power source.

17. The wearable video recording system according to claim 1, wherein a link between the untrusted controller and a source of the unpredictable data is mediated over a telecommunications service.

18. A wearable video recording system with time-bracketed authentication, comprising:

an article, including a spine, wearable by a user;

a recording device, supported on the spine, to generate a recording of a scene;

an affecter subsystem, supported on the spine, to influence the scene being recorded with unpredictable data; and

an untrusted controller coupled to the recording device and the affecter subsystem,

the untrusted controller being receptive of the unpredictable data from a single trusted source or one or more somewhat-trusted sources, which the untrusted controller communicates to the affecter subsystem, and being configured to transmit at least hashed digests of the recording to a single trusted repository or one or more somewhat-trusted repositories.

19. A method of managing recorded information, comprising:

recording, at an untrusted controller, a scene influenced by the recorder with unpredictable data received from a single trusted source or one or more somewhat trusted sources;

transmitting at least hashed digests of the recording from the untrusted controller to a single trusted repository or one or more somewhat trusted repositories;

freely publicizing hardware design and source code for the single trusted source, the one or more somewhat trusted sources, the single trusted repository and/or the one or more somewhat trusted repositories; and

providing restricted access to client subsystem hardware and software information relating to the untrusted controller.

20. The method according to claim 19, wherein the hardware design and source code for the single trusted source, the one or more somewhat trusted sources, the single trusted repository and/or the one or more somewhat trusted repositories comprises a description of a physical random number generator thereof.
