Biometrics, according to Foster, “is the science of using technology to automatically identify an individual based on physical, biological, and behavioral characteristics.” There are two classification systems in biometrics and they are: physiological and behavioral. Physiological characteristics pertain to fingerprints, facial recognition, DNA, hand geometry, the shape of your body, iris recognition, etc. Behavioral characteristics pertain to voice recognition, handwriting, the way that you walk, etc. There are also two categories for the use of this biometric information and they are: access control, and remote identification. Access control pertains to the prevention of others from gaining access to information. Remote identification helps to identify a person through fingerprints or hand geometry. According to globalsecurity.org (2000-2010) they have given biometric technologies the following characteristics:
Universality: Every person should have the characteristic. People who are mute or without fingerprints will need to be accommodated in some way.
Uniqueness: Generally, no two people have identical characteristics. However, identical twins are hard to distinguish.
Permanence: The characteristics should not vary with time. A person’s face, for example, may change with age.
Collectability: The characteristics must be easily collectible and measurable. Performance: The method must deliver accurate results under varied environmental circumstances.
Acceptability: The general public must accept the sample collection routines. Nonintrusive methods are...
