Introduction

Biometrics willing emerge as the sovereign mould of identification and access control in the joined States. This paper reports on biometrics as a revolutionary field, which is employ for identification of human characteristics (i.e. retinal scans, fingerprints) for the purpose of authenticating that individual. This potentially can be used wherever identification is compulsory for security or other reasons for access control. Currently, there argon other numerous forms of access control identity cards, passwords, charismatic strips, codes etc. that are being used. Biometrics is new form of access control which is expensive, requires sophisticated technological infrastructure and macrocosm of a large database. There may also be political and social resistance to its application. However, with growing security concerns in a post 9-11 world and increasing value tuition, biometrics may become the most secure means for accessing information and is likely to progressively replace other forms of identification, especially in sensitive applications. Over time, its use will increase, which, in turn, will reduce costs.
Description of the technology

Biometrics generally operates using the proficiency of enrolment and comparison.



Prior to any authentication/verification attempts, a drug user is enrolled by creating a reference profile (or template) base on the desired physical attribute. The resulting template is associated with the identity of the user and stored for later use. When attempting to authenticate/verify, the users physical attribute is then metrical and compared with the previously stored reference profile. The result of the comparison is then used to both accept or reject the user or verify his identity. There are two types of biometrics i.e. physiological and Behavioral. Behavioral biometrics is generally used for verification dapple Physiological biometrics can be used for either identification or verification.
