Biometric technology provides the only form of identification that is truly unique to an individual. The term ‘Biometrics’ refers to the field devoted to identification of individuals using biological traits. The technology broadly includes the recording and recognition of hand geometry, fingerprint, palm, iris, signature, skin, vein, or voice data. This achieves real time identity verification against records that are inextricably linked to the person, and is considered a higher level of security as it is not based on either something someone knows (a code or password) or something someone has (a token, or card).
Electronic digital templates are encrypted and stored and used for comparison. The templates are usually encrypted to such a high level that they cannot be manipulated. Biometrics offers more than identification simply for physical access control purposes. There are a multitude of other applications of the technology, including verification for financial transactions, network / PC logon, and time and attendance. | When an unidentified end-user is known to be enrolled in the biometric system. Opposite of ‘Open-Set Identification'. |
| | Biometrics is set to pervade key aspects of our economy and daily lives. In the UK, the government intends to introduce a British national identity card, linked to a national identity database. The cards and database will record biometric data, including fingerprints, digitised facial scan and iris scan. It is expected that by 2013 up to 80% of the working population will have some kind of biometric identity document, with the cards becoming compulsory then. |
