Accurate data is the backbone of good Governance. There seems to be no common master data of citizens in India. Every department/ministry has its own database and often the information of the same citizen is recorded differently in each of these databases. Though UID is a step forward in the direction of creating a citizens database, It is associated with the biometric identity of the person. In the government there is always a need of comparing different databases on the basis of demographic and householding information for the purpose of launching targeted welfare programs and new schemes.
Moreover for law enforcement, the profiling search is often on the demographic parameters rather than on a unique identity.
Therefore it is extremely important to have accurate data of citizens in the databases of the respective departments, and creating a unique set of citizens data is challenge owing to the gigantic volumes and poor data quality. There are no defined standards for writing names and addresses. Names and addresses are subject to variations and transcription errors. This leads to multiple enrollments of the same citizen to the program causing huge loss to exchequer. Existing technologies require very large hardware and unpredictable outcome due to limitations of scalability.
