Abstract

An access control system is disclosed comprising a credential reader arranged to gather at least one credential from a person desiring to pass through an access point associated with the access control system, the system being arranged to use the at least one credential to provide an indication about the identity of the person. The system also comprises at least one access control device controlling access through a respective access point such that a person is allowed or denied access dependent on whether the person is positively identified, and a data storage device that stores data indicative of a current security level applicable for each access point associated with the system, the security level defining the criteria required to provide a positive identification of the person. Stored security level data can be modified to change the criteria required for positively identifying a person.

Claims

1. An access control system comprising:

a credential reader arranged to gather at least one credential from a person desiring to pass through an access point associated with the access control system, the system being arranged to use the at least one credential to provide an indication as to the identity of the person;

at least one access control device arranged to control access through a respective access point such that access by a person is allowed or denied dependent on whether a positive decision as to the identity of the person is obtained; and

a data storage device arranged to store security level data indicative of a current security level applicable for the or each access point associated with the system, the security level defining the criteria required to provide a positive decision as to the identity of the person,

wherein the system is arranged to facilitate modification of the stored security level data so as to change the criteria required to be satisfied in order to provide a positive indication as to the identity of a person.

2. An access control system as claimed in claim 1, wherein the system is arranged to facilitate modification of the stored security level data by an operator.

3. An access control system as claimed in claim 2, wherein the system is arranged such that only an authorised operator is able to modify the stored security level data.

4. An access control system as claimed in claim 1, wherein the security level data associated with each access point is individually modifiable by an operator.

5. An access control system as claimed in claim 1, wherein the system is arranged so that multiple access points are groupable together and the security level data associated with a group of access points are modifiable simultaneously by an operator.

6. An access control system as claimed in claim 1, wherein the system is arranged to facilitate modification of the stored security level data automatically based on defined modification rules.

7. An access control system as claimed in claim 6, wherein the modification rules define the security level data according to the time of day, or day of the week.

8. An access control system as claimed in claim 6, wherein the modification rules are modifiable by an operator.

9. An access control system as claimed in claim 1, wherein the security level defines the number of credentials required to be gathered from a person in order to provide a positive indication as to the identity of the person.

10. An access control system as claimed in claim 1, wherein the system comprises a wireless card reader for wirelessly reading an access card having an identifier indicative of a person stored on the card, and the credentials comprise the identifier.

11. An access control system as claimed in claim 1, wherein the system comprises a biometric reader arranged to gather biometric information from a person, and the credentials comprise the biometric information.

12. An access control system as claimed in claim 1, wherein the system comprises a keypad arranged to enable a person to enter a PIN number, and the credentials comprise the PIN number.

13. An access control system as claimed in claim 1, wherein the system comprises a high security level wherein at least 3 credentials are required to be gathered from a person in order to provide a positive indication as to the identity of the person, a medium security level wherein 2 credentials are required to be gathered from a person in order to provide a positive indication as to the identity of the person, and a low security level wherein 1 credential is required to be gathered from a person in order to provide a positive indication as to the identity of the person.

14. An access control system as claimed in claim 1, wherein the security level defines the maximum false acceptance rate allowable for a person desiring to gain passage through an access point.

15. An access control system as claimed in claim 1, wherein the system is arranged to store reference credential data, to compare the reference credential data with corresponding gathered credential data, and to provide a positive or negative indication as to the identity of the person based on the comparison.

16. An access control system as claimed in claim 1, wherein the system comprises a network that may be an address based network, such as an IP based Ethernet network.

17. An access control system as claimed in claim 16, wherein the system comprises an access control station arranged to carry out the comparison between the reference credential data and the corresponding gathered credential data, the access control device being arranged to send gathered credential data to the access control station through the network.

18. An access control system as claimed in claim 17, wherein the security level data is stored at the access control station.

19. An access control system as claimed in claim 15, wherein the access control device is arranged to carry out the comparison between the reference credential data and the corresponding gathered credential data.

20. An access control system as claimed in claim 18, wherein the reference credential data is stored at the access control station.

21. An access control system as claimed in claim 18, wherein the security level data associated with an access point is stored at the access control device associated with the access point.

22. An access control system as claimed in claim 15, wherein the credential reader is arranged to carry out the comparison between the reference credential data and the corresponding gathered credential data.

23. An access control system as claimed in claim 22, wherein the reference credential data is stored at each credential reader.

24. An access control system as claimed in claim 22, wherein the security level data associated with an access point is stored at the credential reader associated with the access point.

25. An access control system as claimed in claim 1, comprising a terminal usable by an operator to modify the stored security level data.

26. An access control system as claimed in claim 25, wherein the terminal comprises a personal computer, a PDA, or a tablet computer.

27. An access control system as claimed in claim 1, wherein each access control device is arranged to control access through multiple access points.

28. An access control system as claimed in claim 1, comprising a sensor arranged to detect whether the access point is open or closed, and an alarm device arranged to produce an audible and/or visible alarm when the sensor detects that the access point is open in the absence of a positive indication as to the identity of a person.
