De-Duplication of Person's Identity Using Multi-Modal Biometrics.
PhD thesis, Indian Institute of Technology Hyderabad.
Abstract
The objective of this work is to explore approaches to create unique identities by the de-duplication process using multi-modal biometrics. Various government sectors
in the world provide different services and welfare schemes for the beneffit of the people in the society using an identity number. A unique identity (UID) number assigned for
every person would obviate the need for a person to produce multiple documentary proofs of his/her identity for availing any government/private services. In the process
of creating unique identity of a person, there is a possibility of duplicate identities as the same person might want to get multiple identities in order to get extra beneffits from the Government. These duplicate identities can be eliminated by the de-duplication process using multi-modal biometrics, namely, iris, ngerprint, face and signature. De-duplication is the process of removing instances of multiple enrollments of the same person using the person's biometric data. As the number of people enrolledinto the biometric system runs into billions, the time complexity increases in the de duplication process. In this thesis, three different case studies are presented to address the performance issues of de-duplication process in order to create unique identity of a person.
