An Efficient Approach to Improve Response Time in Multibiometric Patterns Retrieval From Large Database

Biometric technologies are automated methods of verifying or recognizing the identity of a living person based on a physiological or behavioural characteristics. In a biometric identification system, the identity corresponding to the input data (probe/investigation) is typically determined by comparing it against the templates of all identities in a database (gallery).Exhaustive/in-depth matching against a large number of identities increases the response time of the system and may also reduce the accuracy of identification. One way to reduce the response time is by designing biometric templates that allow for rapid matching. An alternative approach is to limit the number of identities against which matching is performed based on criteria that are fast to evaluate.
