India’s Minister of State for Planning Rao Inderjit Singh provided Rajya Sabha (Council of States) with new data regarding India’s unique biometric identity number system (AADHAAR) for residents, according to a report by Business Standard.
The information included usage of basic demographic and biometric data (ten fingerprints, two iris images) with a photograph to identify a resident after a process of biometric de-duplication, which helps to ensure an accuracy rate of more than 99%.
The data collected during enrolment process is immediately encrypted and transmitted to Central Identities Data Repository (CIDR) of UIDAI for further processing.
Following a series of validation checks, residents’ biometrics are compared against the existing UIDAI database, on a 1:N matching basis, to check if the resident has previously enrolled, said Singh.
Each day, over 700 trillion matches are conducted to ensure a comprehensive de-duplication process, which features various stages including automated data validation, manual quality checks, demographic de-duplication, and biometric de-duplication.
So far, more than 9 crore (90 million) enrollment packets have been rejected after they failed to meet strict quality and de-duplication criteria.
The Indian government is continuously monitoring and observing the Aadhaar database’s quality and veracity, while a dedicated Fraud Investigation and Analytics team is checking to ensure the database complies with various fraud detection rules.
Additionally, the government sporadic conducts a data analysis of the UIDAI database to determine if the system has any fraudulent patterns.
