Biometric verification systems can easily detect different distinguishing biometrical traits. It can identify an individual based on specific characteristics. Biometric verification systems authenticate or verify identifies of individuals in both digital and physical scenarios.
It comes in various unique identifiers such as voice recognition, fingerprints, retina, DNA, iris, finger vein, hand geometry, and signature.
The fingerprint is one of the earliest forms of biometric identification. Historians discovered examples of thumbprints used as individual identification on seals by people in ancient China.
Modern biometric verification systems are quite advanced and continue to evolve. With the advent of computerized databases and the digitization of analog data, instantaneous individual identification is now possible.
Verification versus Identification Systems
Government and business entities use biometrics for different purposes. They are usually part of either an identification system or a verification system. The differences between these two types of systems can make a huge difference in system speed. They can also make a difference in system accuracy as the database size continues to increase.
This type of system seeks to determine whether an individual is who he/she claims to be. With this system, a person presents himself/herself as a specific individual. The verification system checks his/her biometric data against an existing profile linked to the individual’s file to find a match.
Biometric verification systems are often one-on-one matching systems. They try to match biometrics presented by people against specific biometrics already on file. Since such systems just need to compare submitted biometric data to biometrics stored in the system, they tend to generate results quite fast. They are also more accurate than identification systems.
ID systems are not the same as verification systems. They seek to identify unknown biometrics or unknown individuals. Identification systems determine who a person is, and compare the biometrics presented against all other biometrics in the database. Forensic databases, for example, often operate as identification systems.
Why Biometric Verification is Effective
Assume you just verified a crucial document. You may need a biometric verification system to confirm that the document belongs to the individual making the transaction. Biometrics, in other words, add an extra layer of protection against impersonation attacks and stolen IDs. Biometrics is also a simple and time-saving task for users.
Biometrics verification also minimizes customer friction and protects against a wide range of fraud attack vectors. According to research findings by IBM, about 87 percent of business entities would consider using this form of verification in the future. Additionally, 92 percent of businesses rank it as “very effective” or “effective” to secure identity data.
