Abstract

The subject matter described herein generally relates to methods and systems for controlling access to services and more specifically relates to a method and a system for controlling access to a variety of services within security sensitive sites. In one embodiment, the invention provides a system for controlling access to a plurality of services within an area, each service of the plurality of services being associated with a service identifier identifying the service, the system comprising: at least one service device storing a service identifier for identifying a service among the plurality of services, each service device covering a proximity zone within the area and being capable of activating the service identifier stored by the service device for the user, in response to the detection of a user in the proximity zone; and an access control subsystem to control the access of a user to a service identified by a service identifier activated for the user.

Claims

1. A system for controlling access to a plurality of services within an area, each service of the plurality of services being associated with a service identifier identifying the service, the system comprising:

at least one service device storing a service identifier for identifying a service among the plurality of services, each service device covering a proximity zone within the area and being capable of activating the service identifier stored by the service device for the user, in response to the detection of a user in the proximity zone; and

an access control subsystem to control the access of a user to a service identified by a service identifier activated for the user.

2. The system of claim 1, wherein each user is equipped with user equipment storing a user equipment identifier, the at least one service device being capable of activating the service identifier by tagging the user equipment with the service identifier.

3. The system of claim 2, wherein the access control subsystem comprises

location means to determine location data identifying the position of the user equipment within the area, in response to the detection of the user equipment within the area;

a processing unit, interacting with the location means, to compute an authorization token from the service identifier activated for the user, the user equipment identifier stored in the user equipment, and the location data determined by the location means.

4. The system of claim 3, wherein the authorization token includes the service identifier activated for the user, the equipment identifier identifying the user equipment, and an authorization value.

5. The system of any of claim 3, wherein the user is granted or denied access to the service based on the authorization token and at least one predefined service access rule.

6. The system of claim 2, wherein the at least one service device is equipped with proximity communication means covering the proximity zone within the area for communication with the user equipment located in the proximity zone and having communication means paired with the proximity communication means.

7. The system of claim 6, wherein the at least one service device is arranged to transmit the service identifier to the user equipment through the proximity communication means, thereby tagging the user equipment.

8. The system of claim 6, wherein said proximity communication means includes short-range radio frequency communication means.

9. The system of claim 6, wherein the proximity communication means includes RFID communication means and the service device comprises an RFID interrogator interacting with an RFID proximity tag in the user equipment.

10. The system of claim 9, wherein the proximity communication means use high frequency signaling.

11. The system of claim 9, wherein the proximity communication means includes passive type RFID communication means.

12. The system of claim 3, wherein the location means comprises area communication means covering the area for communication with the user equipment located in the area and having communication means paired with the area communication means.

13. The system of claim 12, wherein the area communication means includes short-range radio frequency communication means.

14. The system of claim 12, wherein the area communication means comprises a set of receivers arranged to cover the area.

15. The system of claim 14, wherein the area communication means includes RFID communication means, the location means includes an RFID reader capable of communicating with an RFID location tag included in the user equipment, through the set of receivers, and a calculator for computing the location data.

16. The system of claim 15, wherein the RFID area communication means uses at least one of:

ultra-wide band signaling or WiFi signaling.

17. The system of claim 14, wherein the location data are derived from distances between each receiver and the user equipment.

18. The system of claim 3, wherein the processing unit uses at least one authorization table stored in a database to compute the authorization token.

19. A device for interacting with a system for controlling access to a plurality of services within an area, the device comprising:

storage means for storing a user equipment identifier and being capable of storing at least one service identifier received from a service device, in response to the activation of the service identifier by the service device.

20. A method for controlling access to a plurality of services within an area, each service of the plurality of services being associated with a service identifier identifying the service, the method comprising:

providing at least one service device for storing a service identifier identifying a service among the plurality of services, each service device covering a proximity zone within the area;

in response to the detection of a user in the proximity zone of a service device, activating the service identifier stored by the service device for the user; and

in response to a service identifier being activated for a user located in the area, controlling access of the user to the service identified by the activated service identifier.
