Fusion of the biometrics information can occur at different stages of a recognition system. Biometrics is the technical term for body measurements and calculations.
Behavioral characteristics are related to the pattern of behavior of a person, including but not limited to typing rhythmgait and voice.
Journal of Southern African Studies Proper biometric use is very application dependent.

However, such technology is generally more cumbersome and still has issues such as lower accuracy and poor reproducibility over time. In such a sense, biometrics could play a pivotal role in supporting and promoting respect for human dignity and fundamental rights. Biometrics authentication or realistic authentication [note 1] is used in computer science as a form of identification and access control. Although this increases the restrictions on the protection system, it makes the cancellable templates more accessible for available biometric technologies.
The following are used as performance metrics for biometric systme Archived from the original on ststem September Certain biometrics will be better than others based on the required levels of convenience and security. Note that it is crucial that storage and retrieval of such systems themselves be secure if the biometric system is to be robust. Biometric identifiers are the distinctive, measurable characteristics used to label and describe individuals.
If a cancelable feature is compromised, the distortion characteristics are changed, and the same biometrics is mapped to a new template, which is used subsequently. In his pvf in Biomrtric International Review, Prof Nayef Al-Rodhan cautions about the high risks of miscalculations, wrongful accusations and infringements of civil liberties. The stark expansion of biometric technologies in both the public and private sector magnifies this concern. Agamben refers to the two words used by Ancient Greeks for indicating “life”, zoewhich is the life common to animals and humans, just life; and bioswhich is life in the human context, with meanings and purposes.
Biometrics have been considered also instrumental to the development of state authority  to put it in Foucauldian terms, of discipline and biopower . Spoof attacks consist in submitting fake biometric traits to biometric systems, and are a major threat that can curtail their security.
Selection of biometrics in any practical application depending upon the characteristic measurements and user requirements.

Constraints on the Use of Biometric Identification Systems”. It was first proposed by Ratha et al. Retrieved 20 February Retrieved 1 October In case of feature level fusion, the data itself or the features extracted from multiple biometrics are fused.
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.
The Center for Global Development. US Department of Homeland Security. First, bilmetric an adaptive biometric system, one no longer needs to collect a large number of biometric samples during the enrollment process. Archived from the original on 17 October doenload The block diagram illustrates the two basic modes of a biometric system.
It is a biometrics-based digital identity assigned for a person’s lifetime, verifiable  online instantly in the public domain, at any time, from anywhere, in a paperless way. Archived from the original on 7 January Archived from the original PDF on 25 March If a token or a password is lost or stolen, it can be cancelled and replaced by a newer version.

Multi-modal biometric systems are commonly believed to be intrinsically more robust to spoof attacks, but recent studies  have shown that they can be evaded by spoofing even a single biometric trait. The selection of a particular biometric for use in a specific application involves a weighting of several factors.
Biometric voice recognition is separate and distinct from speech recognition with the latter being concerned with accurate understanding of speech content rather than identification or recognition of the person speaking. The increasing commodification of biometrics by the private sector adds to this danger of loss of human value. A template is a synthesis of the relevant characteristics extracted from the source.
Some of the proposed techniques operate using their own recognition engines, such as Teoh et sgstem. A vector of numbers or an image with particular properties is used to create a template. Feature level fusion is believed to be more effective than the other levels of fusion because the feature set contains richer information about the input biometric data than the matching score or the output decision of a classifier.
The technology will analyze physiological features such as eye movement, body temperature, breathing etc.
