Using fingerprints as tables primary keys

Oracle Database Tips by Donald Burleson

Oracle allows positive identification of people with fingerprint biometric systems and the Oracle DBA can easily implement database that will store fingerprints and provide a positive (8 point match) to identify end users.

Fingerprint recognition has become inexpensive and reliable and low-cost fingerprint readers are now available for positive identification.  The output from these devices is interfaced with Oracle where the master fingerprint database resides.

The US government is using biometrics for positive identification and there are several vendors with specific tools for the solicitation of fingerprints:

You can also use remote biometric devices to interface with Oracle for the positive identification of people in remote areas:

The remote biometrics system can use ssh via a satellite link-up to quickly capture and compare the captured fingerprint to an Oracle database with millions of fingerprints and return identification with sub-second response times.

Using fingerprints as table primary keys

Whenever you are designing tables about specific people and the individuals have direct access to only their records, it is possible to design a method to allow the end-user to offer their fingerprint for positive identification.

Oracle has offered several tools and utilities to aid in the passwords management problem, but none offer a complete biometric solution:

  • Single Sign-On - Many tools such as Oracle Application Server 10g (and Oracle9iAS) offer a single sign-on facility (SSO) to allow a single place for password management.
  • Oracle Biometrics Manager - Oracle8 Enterprise Manager (OEM) offered a Biometrics Manager to allow the DBA to administer biometric credentials (fingerprints) of Oracle database end-users.
  • Remote Authentication Dial-In User Service (RADIUS) - Oracle has a RADIUS biometrics environment (and "smart cards") whereby access is controlled at the Oracle*Net level. 

Also, see this article on Oracle primary key management with biometric primary keys.

For complete support for biometric single sign-on for any Oracle databases, just call for Oracle biometrics support.
