Abstract

Methods and apparatus for controlling access to a secure facility are disclosed, wherein a determination of whether access is permitted is based at least in part on a digital image of one or more predetermined features of the secure facility. In an exemplary method, an image of a predetermined feature of the secure facility is captured by a user device and compared to stored security data corresponding to the secure facility. A determination of whether access to the secure facility is permitted is made, based on the results of the comparison. The predetermined feature may be a security mechanism attached to the secure facility, for example, or may be textual information, a graphical image, or a machine-readable code posted at the security facility.

Claims

1. A method of controlling access to a secure facility, the method comprising:

comparing stored security data to a digital image, captured by a user device, of a predetermined feature of the secure facility; and

determining whether access to the secure facility is permitted based on the comparison.

2. The method of claim 1, wherein the predetermined feature comprises one or more of:

a security mechanism attached to the secure facility;

textual information posted at the secure facility;

a machine-readable code posted at the secure facility; and

an image posted at the security facility.

3. The method of claim 1, wherein comparing stored security data to the digital image comprises extracting one or more characteristic features from the digital image and comparing the characteristic features to a stored image profile corresponding to the secure facility.

4. The method of claim 1, wherein comparing stored security data to the digital image comprises recognizing text from the digital image and comparing the recognized text to text included in the stored security data or converting a machine-readable code included in the digital image to an electronic identifier and comparing the electronic identifier to a secure facility identifier included in the stored security data, or both.

5. The method of claim 1, wherein determining whether access to the secure facility is permitted is further based on at least one user-specific authentication factor.

6. The method of claim 5, wherein the at least one user-specific authentication factor comprises one or more of:

a user voice sample;

a user fingerprint sample;

a user-supplied personal identification code;

or

a device identifier associated with the user device.

7. The method of claim 1, further comprising determining location information for the user device used to capture the digital image, wherein determining whether access to the secure facility is permitted is further based on the location information.

8. A portable electronic device comprising a camera unit and a processing unit, the processing unit configured to:

compare stored security data to a digital image, captured by the camera unit, of a predetermined feature of a secure facility; and

determine whether access to the secure facility is permitted based on the comparison.

9. The portable electronic device of claim 8, wherein the processing unit is configured to

compare the stored security data to the digital image by:

recognizing text from the digital image and comparing the recognized text to text included in the stored security data;

or

converting a machine-readable code included in the digital image to an electronic identifier, and comparing the electronic identifier to a secure facility identifier included in the stored security data;

or both.

10. The portable electronic device of claim 8, wherein the processing unit is configured to determine whether access to the secure facility is permitted based further on at least one user-specific authentication factor.

11. The portable electronic device of claim 10, wherein the at least one user-specific authentication factor comprises one or more of:

a user voice sample;

a user fingerprint sample;

a user-supplied personal identification code;

or

a device identifier associated with the portable electronic device.

12. The portable electronic device of claim 8, further comprising a positioning unit, wherein the processing unit is further configured to determine location information for the portable electronic device, using the positioning unit, and to determine whether access to the secure facility is permitted based further on the location information.

13. The portable electronic device of claim 8, further comprising a wireless communication unit, wherein the processing unit is further configured to retrieve location information for the portable electronic device, using the communication unit, and to determine whether access to the secure facility is permitted based further on the location information.

14. The portable electronic device of claim 8, further comprising a short-range wireless transmitter, wherein the processing unit is further configured to transmit an unlocking command, using the short-range wireless transmitter, to an electronic locking device barring access to the secure facility.

15. The portable electronic device of claim 8, further comprising a display device, wherein the processing unit is further configured to display a user-readable access code on the display.

16. A portable electronic device, comprising a camera unit, a wireless communication unit, and a processing unit, the processing unit configured to:

capture a digital image of a predetermined feature of a secure facility, using the camera unit;

send the digital image, using the wireless communication unit, to a remote processing node for a determination of whether access to the secure facility is permitted; and

receive, via the wireless communication unit, a security access token for use in accessing the secure facility.

17. The portable electronic device of claim 16, wherein the processing unit is further configured to send at least one user-specific authentication factor to the remote processing node for the determination of whether access to the secure facility is permitted.

18. The portable electronic device of claim 16, wherein the processing unit is further configured to receive, via the wireless communication section, a security access token from the remote processing node.

19. The portable electronic device of claim 18, further comprising a display unit, wherein the processing unit is further configured to display the security access token and one or more dummy tokens on the display unit.

20. The portable electronic device of claim 18, further comprising a short-range wireless transmitter, wherein the security access token comprises an electronic code for use by an electronic locking device barring access to the secure facility, and wherein the processing unit is further configured to transmit the electronic code, using the short-range wireless transmitter, to the electronic locking device.

21. The portable electronic device of claim 16, further comprising a positioning unit, wherein the processing unit is further configured to determine location information for the portable electronic device, using the positioning unit, and to send the location information to the remote processing node for the determination of whether access to the secure facility is permitted.

22. The portable electronic device of claim 16, wherein the processing unit is further configured to retrieve location information for the portable electronic device, using the wireless communication unit, and to send the location information to the remote processing node for the determination of whether access to the secure facility is permitted.
