Biometrics term paper

The dictionary definitions miss a vital aspect. A person may adopt different identities at various times during a life-span, and some individuals maintain several at once.

Biometric functionality[ edit ] Many different aspects of human physiology, chemistry or behavior can be used for biometric authentication.

The selection of a particular biometric for use in a specific application involves a weighting of several factors. Universality means that every person using a system should possess the trait.

Uniqueness means the trait should be sufficiently different for individuals in the relevant population such that they can be distinguished from one another. Permanence relates to the manner in which a trait varies over time. Measurability collectability relates to the ease of acquisition or measurement of the trait.

In addition, acquired data should be in a form that permits subsequent processing and extraction of the relevant feature sets. Performance relates to the accuracy, speed, and robustness of technology used see performance section for more details. 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.

Circumvention relates to the ease with which a trait might be imitated using an artifact or substitute. Proper biometric use is very application dependent. Certain biometrics will be better than others based on the required levels of convenience and security.

Three steps are involved in the verification of a person. In the second step, some samples are matched with reference models to generate the genuine and impostor scores and calculate the threshold.

Third step is the testing step. This process may use a smart cardusername or ID number e. PIN to indicate which template should be used for comparison. 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.

The first time an individual uses a biometric system is called enrollment. During the enrollment, biometric information from an individual is captured and stored.

In subsequent uses, biometric information is detected and compared with the information stored at the time of enrollment. Note that it is crucial that storage and retrieval of such systems themselves be secure if the biometric system is to be robust. The first block sensor is the interface between the real world and the system; it has to acquire all the necessary data.

Most of the times it is an image acquisition system, but it can change according to the characteristics desired.A biometric passport (also known as an e-passport, ePassport or a digital passport) is a traditional passport that has an embedded electronic microprocessor chip which contains biometric information that can be used to authenticate the identity of the passport holder.
