Abstract

A security system includes a central computer connected through a network to a plurality of remote computers. A database of user information is created at the central computer and copied to the remote computers. The remote computers include user interfaces for the collection of user information such a fingerprint and a user ID. When a user provides this information, the remote computer compares it to the database. If a match is generated, the remote computer authorizes access through an associated passageway. The security system can also be used to monitor user access times and to present messages to users.

Claims

1. A security system comprising:

an administration unit configured to generate a database of biometric features and user ID'"'"'s each associated with a specific person, wherein the administration unit includes;

a first input configured to capture a representation of a biometric feature and to generate a first electronic representation of the biometric feature;

a second input configured to receive a user ID; and

a computer processor operationally coupled with the first and second inputs and configured to save the first electronic representation of the biometric feature and the user ID in the database, wherein the biometric feature is associated with the user ID; and

a control unit operationally coupled with the administration unit and configured to control an access device, wherein the control unit includes;

a first input configured to capture a representation of the biometric feature and to generate a second electronic representation of the biometric feature;

a second input configured to receive a character string; and

a computer processor operationally coupled with the first and second inputs and with the database and configured to compare the second electronic representation of the biometric feature with the database of biometric features and to determine whether the comparison generates a biometric match, and to compare the character string with the database of user ID'"'"'s to determine whether the comparison generates a user ID match.

2. The security system of claim 1, further comprising an auxiliary unit operationally coupled with the control unit, wherein the auxiliary unit and the control unit are situated on opposite sides of an access point, wherein the auxiliary unit includes:

a first input configured to capture a representation of the biometric feature and to generate a third electronic representation of the biometric feature; and

a second input configured to receive a character string; and

wherein the first and second inputs of the auxiliary unit are operationally coupled with the computer processor of the control unit, and wherein the computer processor of the control unit is configured to compare the third electronic representation of the biometric feature with the database of biometric features to determine whether the comparison generates a biometric match, and to compare the character string with the database of user ID'"'"'s to determine whether the comparison generates a user ID match.

3. The security system of claim 2, wherein the biometric feature comprises a fingerprint.

4. The security system of claim 2, wherein the biometric feature comprises features of the human face.

5. The security system of claim 2, further comprising the access device, wherein the access device releases when the computer processor of the control unit detects the biometric match and the user ID match.

6. The security system of claim 5, wherein the detection of the biometric match and the user ID match are based upon data received from the first and second input of the control unit.

7. The security system of claim 5, wherein the detection of the biometric match and the user ID match are based upon data received from the first and second input of the auxiliary unit.

8. The security system of claim 5, wherein the access device comprises an electric circuit configured to control a magnetic field.

9. The security system of claim 1, further comprising:

a plurality of control units each operationally coupled with the administration unit and configured to control an access device; and

a plurality of auxiliary units each operationally coupled with one of the plurality of control units, wherein the auxiliary unit and the control unit pairs are situated on opposite sides of an access point.

10. A security system especially suited for controlling access within a building having a limited number of access points each having an interior side and an exterior side comprising:

a plurality of locking mechanisms each associated with one access point and configured to prevent passage through the access point in a closed position and to permit passage through the access point in an open position;

a plurality of interior user interfaces each associated with one access point and configured to generate a representation of a biometric feature and to receive a user ID from a user;

a plurality of exterior user interfaces each associated with one access point and configured to generate a representation of a biometric feature and to receive a user ID from a user;

a computer server having a database of user information including a plurality of records each of which includes a representation of a biometric feature, and a user identification; and

a plurality of local computers each associated with one access point and operationally coupled with the associated interior user interface and the exterior user interface and operationally coupled through a network connection to the computer server, wherein each one of the plurality of local computers controls the locking mechanism associated with the same access point and wherein each of the plurality of local computers are positioned on an interior side of the associated access point.

11. The security system of claim 10, wherein each of the plurality of locking mechanisms comprise a coil configured to pass an electric current that generates a magnetic field in the closed position.

12. The security system of claim 10, wherein each of the plurality of interior user interfaces comprises:

a touch screen configured to present messages to a user and to receive the user ID from the user; and

a fingerprint sensor configured to generate the representation of the biometric feature.

13. The security system of claim 10, wherein each of the exterior user interfaces comprises:

a keypad configured to receive the ID from the user; and

a fingerprint sensor configured to generate the representation of the biometric feature.

14. The security system of claim 10, wherein each of the plurality of records stored in the database of the computer server further include defined access privileges.

15. The security system of claim 10, wherein the computer server further includes a database of time records each associated with a user identification, wherein the time records detail the time in and time out of each user.

16. The security system of claim 10, wherein each of the plurality of local computers comprises a database of user information including a record for each authorized user that includes a representation of a biometric feature and an ID.

17. The security system of claim 16, wherein each of the plurality of local computers are configured to open the associated locking mechanism when the biometric feature and the user ID received from either of the associated interior or exterior user interfaces generates a match with the database of user information stored on the local computer.

18. The security system of claim 17, wherein the database of user information stored on the local computer is a copy of the database of user information on the server computer.

19. The security system of claim 10, wherein each of the plurality of local computers are configured to receive time in commands and time out commands from a user and to transmit a user identification to the computer server in response to such commands.

20. A method of operating a security system comprising the steps of:

establishing a central database of user information including records each having a representation of a biometric feature, a user ID and access privileges for each user;

transferring the user information from a central computer to a plurality of remote computers each having a display, a keypad interface and a biometric sensor;

receiving a representation of a biometric feature and a user ID from a user at one of the remote computers;

comparing the biometric feature and the user ID received from the user to the user information at the remote computer;
