Indian government conducts ongoing analysis of biometric identity database
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.
