During enrollment, biometric information from an individual is captured and stored. The first time an individual uses a biometric system is called enrollment. The latter function can only be achieved through biometrics since other methods of personal recognition, such as passwords, PINs, or keys, are ineffective.

Identification mode can be used either for positive recognition (so that the user does not have to provide any information about the template to be used) or for negative recognition of the person "where the system establishes whether the person is who she (implicitly or explicitly) denies to be". The system will succeed in identifying the individual if the comparison of the biometric sample to a template in the database falls within a previously set threshold. Second, in identification mode the system performs a one-to-many comparison against a biometric database in an attempt to establish the identity of an unknown individual. īiometric Island examining facial image 2D and 3D, voice timbre, and verifying handwritten signature No single biometric will meet all the requirements of every possible application. Certain biometrics will be better than others based on the required levels of convenience and security. Proper biometric use is very application dependent.

Circumvention relates to the ease with which a trait might be imitated using an artifact or substitute.

Acceptability relates to how well individuals in the relevant population accept the technology such that they are willing to have their biometric trait captured and assessed.

Performance relates to the accuracy, speed, and robustness of technology used (see performance section for more details).

In addition, acquired data should be in a form that permits subsequent processing and extraction of the relevant feature sets.

Measurability (collectability) relates to the ease of acquisition or measurement of the trait.

More specifically, a trait with good permanence will be reasonably invariant over time with respect to the specific matching algorithm.

Permanence relates to the manner in which a trait varies over time.

Uniqueness means the trait should be sufficiently different for individuals in the relevant population such that they can be distinguished from one another.

Universality means that every person using a system should possess the trait.

Biometric authentication is based upon biometric recognition which is an advanced method of recognising biological and behavioural characteristics of an Individual. (1999) identified seven such factors to be used when assessing the suitability of any trait for use in biometric authentication. The selection of a particular biometric for use in a specific application involves a weighting of several factors. Many different aspects of human physiology, chemistry or behavior can be used for biometric authentication. Since biometric identifiers are unique to individuals, they are more reliable in verifying identity than token and knowledge-based methods however, the collection of biometric identifiers raises privacy concerns about the ultimate use of this information.

More traditional means of access control include token-based identification systems, such as a driver's license or passport, and knowledge-based identification systems, such as a password or personal identification number. Some researchers have coined the term behaviometrics to describe the latter class of biometrics. Behavioral characteristics are related to the pattern of behavior of a person, including but not limited to mouse movement, typing rhythm, gait, signature, behavioral profiling, and credentials. Examples include, but are not limited to fingerprint, palm veins, face recognition, DNA, palm print, hand geometry, iris recognition, retina, odor/scent, voice, shape of ears and gait. Biometric identifiers are often categorized as physiological characteristics which are related to the shape of the body.

It is also used to identify individuals in groups that are under surveillance.īiometric identifiers are the distinctive, measurable characteristics used to label and describe individuals. Biometric authentication (or realistic authentication) is used in computer science as a form of identification and access control. Not to be confused with Biometry.īiometrics are body measurements and calculations related to human characteristics. For the academic journal, see Biometrics (journal).
