Abstract
A method of allowing access to a secure area comprises illuminating an access control token incorporating one or more security markers. Emission from the security markers in response to the illumination is detected and processed to generate an access signature. Access to the secure area is allowed if the generated access signature matches one or more pre-defined access profiles.
Claims21
A method of allowing access to a secure area, the method comprising:
- illuminating an access control token incorporating one or more security markers;
- detecting emission from the one or more security markers in response to the illumination;
- processing the detected emission to generate an access signature;
- comparing the access signature with one or more pre-defined access profiles;
- and
- allowing access to the secure area if the access signature matches one of the one or more pre-defined access profiles.
A method of denying access to a secure area, the method comprising:
- illuminating an access control token incorporating one or more security markers;
- detecting emission from the one or more security markers in response to the illumination;
- processing the detected emission to generate an access signature;
- comparing the access signature with one or more pre-defined deny-access profiles;
- determining that the access signature matches one of the one or more pre-defined deny-access profiles;
- and
- denying access to the secure area.
A device for controlling access to a secure area, the device comprising:
- an illumination source which illuminates an access control token incorporating one or more security markers;
- a detector which detects emission from the one or more security markers in response to the illumination;
- and
- a processor which (i) generates an access signature from the detected emission, (ii) compares the access signature with one or more pre-defined access profiles, and (iii) allows access to the secure area if an access signature matches one of the one or more pre-defined access profiles.
