Abstract

A wireless local area network access point is provided that authenticates users using fingerprint recognition. Users may register fingerprints with the wireless access point with the assistance of an authorized system administrator. When a registered user attempts to access the network, the user may be prompted to provide a fingerprint scan. A fingerprint reader in the user'"'"'s equipment may be used to capture the user'"'"'s fingerprint. The captured fingerprint may be submitted to the wireless access point for comparison with a database of fingerprints of authorized users. If the captured fingerprint is valid, the user may be granted wireless network access by the access point.

Claims

1. A method for using a wireless access point to restrict access to a wireless local area network having an administrator computer and a plurality of user computers, comprising:

at the administrator computer, capturing a fingerprint of a user;

transmitting the captured fingerprint from the administrator computer to the wireless access point;

registering the user with the wireless access point by storing the captured fingerprint from the administrator computer at the wireless access point;

at a computer of the user, capturing a fingerprint of the user to use in logging on to the local area network;

transmitting the newly-captured fingerprint from the computer of the user to the wireless access point;

at the access point, authenticating the user by comparing the newly-captured fingerprint to the stored fingerprint to determine whether there is a match indicating that the newly-captured fingerprint is valid;

if the wireless access point determines that the newly-captured fingerprint is valid, using the wireless access point to provide the user'"'"'s computer with wireless network access to the local area network; and

if the wireless access point determines that the newly-captured fingerprint is not valid, using the wireless access point to deny the user'"'"'s computer wireless network access to the local area network.

2. The method defined in claim 1 wherein registering the user with the wireless access point comprises displaying a new user registration screen for the user on the user'"'"'s equipment, wherein the new user registration screen contains a region into which the user enters a userID.

3. The method defined in claim 1 wherein using the wireless access point to provide the user'"'"'s computer with wireless network access to the local area network comprises using an IEEE 802.11 protocol to provide the user'"'"'s computer with wireless network access to the local area network.

4. The method defined in claim 1 wherein capturing the user fingerprint at the administrator computer comprises displaying selectable options on which fingers to register.

5. The method defined in claim 1 wherein capturing the user fingerprint at the administrator computer comprises using an interactive graphical display of a hand with fingers to select which finger of the user to use to register the user fingerprint.

6. The method defined in claim 1 further comprising displaying at least one confirmation screen for the user at the administrator computer when user registration with the wireless access point is complete.

7. The method defined in claim 1 further comprising using the wireless access point to allow the administrator to select how many fingers are scanned when capturing fingerprints for the wireless access point to authenticate a given user.

8. The method defined in claim 1 further comprising using an external fingerprint scanner that is attached to the user'"'"'s computer to capture fingerprint scans for the wireless access point.

9. The method defined in claim 1 further comprising using a network interface card with an integral fingerprint scanner in the user'"'"'s computer to capture fingerprint scans for the wireless access point.

10. The method defined in claim 1 further comprising authenticating the administrator with the wireless access point using fingerprint verification.

11. The method defined in claim 1 wherein before the fingerprint of the user is captured at the administrator computer, the administrator provides the administrator computer with an adminID and an admin fingerprint for authentication.

12. A method for using a wireless access point to restrict access to a wireless local area network having a plurality of computers of users, comprising:

at a computer of a user, capturing a fingerprint of the user;

transmitting the fingerprint from the computer of the user to the wireless access point over a wireless link between the computer and the wireless access point; and

at the access point, authenticating the user using the transmitted fingerprint.

13. The method defined in claim 12 further comprising registering the user with the wireless access point by capturing a fingerprint of the user during a registration process and storing the captured finger in storage at the wireless access point.

14. The method defined in claim 12 wherein authenticating the user further comprises using a userID to authenticate the user at the wireless access point.

15. The method defined in claim 12 wherein authenticating the user comprises:

using a userID to locate a registered user fingerprint stored at the access point and comparing the located registered user fingerprint to the transmitted fingerprint to determine whether there is a match.

16. The method defined in claim 12 further comprising displaying an error message for the user if the wireless access point determines that the transmitted fingerprint is not valid.

17. The method defined in claim 12 further comprising using a port in the wireless access point to connect the local area network to internet access through a modem.

18. The method defined in claim 12 further comprising:

during fingerprint registration, displaying a screen for the user with graphical hands and fingers to click on to select which fingers to register.

19. The method defined in claim 12 further comprising:

making multiple passes of the user'"'"'s finger to capture the fingerprint of the user with a fingerprint reader.

20. The method defined in claim 19 further comprising:

displaying a screen on an administrator computer that is in communication with the wireless access point; and

in response to administrator interactions with the screen, adjusting how many fingers are to be used when capturing user fingerprint information for authentication with the wireless access point.
