Common Types Of Biometric Identification

Biometric Identification

Biometric identification is a process whereby personal physiological or behavioral characteristics are used for identification purposes. This is commonly used in business for security related activities in sensitive areas to protect or restrict access to data, equipment or property of value. Biometric identification systems are integrated into software and electronic devices. The most common biometric identification technology is discussed further below:

Hand Biometric Identification: The user places his/her hand under a special optical scanning mechanism. The physical characteristics of the hand such as width and shape are verified against an internal database. This type of security access is used for time logging and attendance and access monitoring.

Fingerprint Biometric Identification: The end user places his/her fingerprint into a reading device and a series of identification points are scanned and translated into numerical code for matching the individual's identification details. This is being used by schools as a replacement for identification cards and pin numbers. It speeds up the administration process and eliminates the need for replacing lost, stolen or forgotten ID cards. Common applications include attendance verification, processing cafeteria requests and medication distribution.

Face Biometric Identification: This involves a special face scanning mechanism that scans an individual's face for two and three dimensional geometry, heat distribution within the face and the face skin surface structure. It is commonly used in forensic applications, attendance and access control situations.

Iris Biometric Identification: This biometric identification technology is a high resolution matching process for scanning the irises of an individuals eyes for ascertaining detailed schema of the iris. It is used for biometric intelligence and identification purposes in commercial applications such as airports and border control.

DNA Biometric Identification: The use of DNA biometric identification techniques such as the sequencing of DNA base pairs through molecular probes or the submission of blood sampling. This is widely regarded as the most accurate form of biometric identification due to the characteristics unique to individual DNA.

Key Biometric Identification: This form of authentification uses the manner and rhythmic sequencing of key entry to establish a biometric signature for matching purposes.

Signature Biometric Identification: This is a type of biometric identification that is matched against a database entry. It is considered less reliable because of the susceptibility of signatures to change over time. Behavioral characteristics that are considered include the angle of the pen, the time taken to sign and the acceleration and velocity of the pen. Usually a signature tablet is used to capture the signature.

Voice Biometric Identification: Involves the use of voice analysis through pitch, tone and frequency characteristics for matching purposes.
