Abstract

A method of providing obscurant data includes receiving image data including an image of a target and receiving a preference setting corresponding to the target. Obscurant data of at least a portion of the image data corresponding to the target are determined using the received preference setting. A method of providing surveillance image data includes capturing image data including an image of a target, querying a database to receive a preference setting corresponding to the target, determining the obscurant data of the portion of the image data, and selectively modifying the received image data according to the determined obscurant data to provide the surveillance image data.

Claims

1. A method of providing obscurant data, comprising:

receiving image data including an image of a target;

receiving a preference setting corresponding to the target; and

determining the obscurant data of at least a portion of the image data corresponding to the target using the received preference setting.

2. The method according to claim 1, further comprising selectively modifying the received image data according to the determined obscurant data to provide a surveillance image.

3. The method according to claim 2, wherein the determining step includes determining at least a portion of the image data to be obscured in response to a preference setting requesting privacy and the modifying step includes obscuring the determined at least a portion of the image data.

4. The method according to claim 2, wherein the determining step includes determining at least a portion of the image to be indicated in response to a preference setting requesting increased visibility of the target and the modifying step includes modifying the determined at least a portion of the image data to include data of a visible indicator.

5. The method according to claim 1, further including receiving a unique identifier of the target, wherein the step of receiving a preference setting includes transmitting the received unique identifier to a database and receiving from the database the preference setting corresponding to the unique identifier.

6. The method according to claim 5, the method further comprising receiving a validity period of the unique identifier and determining that the at least a portion of the image data should be obscured only if a present date or time is within the validity period.

7. The method according to claim 5, further including authenticating the unique identifier with respect to selected authority data.

8. The method according to claim 7, wherein the authority data includes a cryptographic key and the authenticating step including validating the unique identifier using the cryptographic key and a digital signature of the unique identifier.

9. The method according to claim 1, wherein the image data correspond to a visibility region, the step of receiving a preference setting including:

transmitting data of the visibility region to a database to determine whether the target is present in the visibility region; and

receiving from the database the preference setting or an indication that the target is not present in the visibility region.

10. The method according to claim 1, further including transmitting to a database a timestamp corresponding to the image data.

11. The method according to claim 1, further including storing the determined obscurant data in a storage device.

12. The method according to claim 11, wherein the storage device is a tamper-evident storage device.

13. The method according to claim 1, wherein the target is selected from the group consisting of a person, a building, a vehicle, or an animal, the determining step including determining a size of the at least a portion of the image data using the received image data.

14. A method of providing surveillance image data, comprising:

capturing image data including an image of a target;

querying a database to receive a preference setting corresponding to the target;

determining obscurant data of at least a portion of the image data corresponding to the target using the received preference setting; and

selectively modifying the image data according to the determined obscurant data to provide the surveillance image data.

15. The method according to claim 14, wherein the image data correspond to a visibility region, wherein the querying step includes querying the database based on the visibility region to determine whether a target is present in the visibility region, and performing the determining and modifying steps for the target determined to be present.

16. The method according to claim 15, wherein the querying step includes providing to the database coordinates of a visibility polygon corresponding to the visibility region.

17. The method according to claim 15, wherein the querying step includes receiving from the database data a masking layer representing one or more area(s) to be masked and the determining step includes determining coordinates in the image data corresponding to the area(s).

18. The method according to claim 14, further including receiving an identity of the target and storing the received identity in association with the preference setting in the database.

19. The method according to claim 14, further including receiving a unique identifier corresponding to the target, the querying step including transmitting the unique identifier to the database.

20. The method according to claim 19, the receiving-identifier step including transmitting a radio-frequency (RF) interrogation signal and receiving an RF identification signal in response, the RF identification signal including data of the unique identifier.

21. The method according to claim 19, the receiving-identifier step including receiving the unique identifier from a location provider.

22. The method according to claim 19, the method further comprising receiving a validity period of the unique identifier and determining that the at least a portion of the image data should be obscured only if a present date or time is within the validity period.

23. The method according to claim 19, further including authenticating the unique identifier with respect to selected authority data.

24. The method according to claim 23, wherein the authority data includes a cryptographic key and the authenticating step including validating the unique identifier using the cryptographic key and a digital signature of the unique identifier.25.

25. The method according to claim 14, further including locating a tag of the target in the image data and decoding a target identifier of the tag, the target identifier visually represented in the image data, wherein the querying step includes transmitting the decoded target identifier to the database.

26. The method according to claim 14, wherein the determining step includes determining the obscurant data using the received image data and the received preference setting.
