Abstract

A fingerprint method for access control includes the steps of: providing an application server (20) for controlling access of different users; providing a database (40) connected to the application server for storing original fingerprint data of each user; scanning a fingerprint of a user through a handheld device (10), and obtaining fingerprint data of the scanned fingerprint; establishing a wireless communication channel between the handheld device and the application server, and transmitting the fingerprint data to the application server through the wireless communication channel; receiving the fingerprint data from the handheld device by the application server; determining whether the fingerprint data is the same as the original fingerprint data of the user in the database; and the user to access an access control device (30) connected to the application server if the fingerprint data is the same as the original fingerprint data stored in the database. A fingerprint system for access control is also provided.

Claims

1. A fingerprint system for access control, the fingerprint system comprising:

an application server for controlling access of different users;

a database, connected to the application server, configured for storing original fingerprint data of each user;

a handheld device comprises;

a fingerprint identification device configured for scanning a fingerprint of a user;

a fingerprint data obtaining module configured for obtaining fingerprint data of the scanned fingerprint;

a transmitting module configured for establishing a wireless communication channel between the handheld device and the application server, and transmitting the fingerprint data to the application server through the wireless communication channel;

the application server comprises;

a receiving module configured for receiving the fingerprint data from the handheld device;

a comparing module configured for determining whether the fingerprint data is the same as the original fingerprint data of the user stored in the database; and

a controlling module configured for allowing the user to access an access control device connected to the application server if the fingerprint data is the same as the original fingerprint data stored in the database.

2. The system according to claim 1, wherein the controlling module is further configured for warning and denying the user access to the access control device if the fingerprint data is not the same as the original fingerprint data stored in the database.

3. The system according to claim 1, wherein the handheld device further comprises an encrypting module configured for encrypting the fingerprint data.

4. The system according to claim 3, wherein the application server further comprises a decrypting module for decrypting the encrypted fingerprint data.

5. A fingerprint method for access control, the method comprising the steps of:

providing an application server for controlling access of different users;

providing a database connected to the application server for storing original fingerprint data of each user;

scanning a fingerprint of a user through a handheld device, and obtaining fingerprint data of the scanned fingerprint;

establishing a wireless communication channel between the handheld device and the application server, and transmitting the fingerprint data to the application server through the wireless communication channel;

receiving the fingerprint data from the handheld device by the application server;

determining whether the fingerprint data is the same as the original fingerprint data of the user in the database; and

allowing the user to access an access control device connected to the application server if the fingerprint data is the same as the original fingerprint data stored in the database.

6. The method according to claim 5, further comprising the step of warning and denying the user access to the access control device if the fingerprint data is not the same as the original fingerprint data stored in the database.

7. The method according to claim 5, further comprising the steps of:

encrypting the fingerprint data after the scanning step, and

decrypting the encrypted fingerprint data before the comparing step.
