Periodic analysis of database to maintain accuracy and integrity of AADHAAR

The methodology for generation of unique identity number (AADHAAR) for residents of India, involves usage of certain basic demographic (name, age, gender and address) and biometric information (ten finger prints, two iris images) with a photograph to uniquely identify a resident after a process of biometric de-duplication. The process of biometric de-duplication helps in ensuring uniqueness to a high degree of accuracy, exceeding 99%. The data collected during enrolment process is immediately encrypted and transmitted to Central Identities Data Repository (CIDR) of UIDAI for further processing. This information was given by the Minister of State (Independent Charge) for Planning, Shri Rao Inderjit Singh in a written reply in Rajya Sabha today.
