What is Unique Identification(UID) and Unique Identification Authority of India (UIDAI)?

What is Unique Identification(UID) and Unique Identification Authority of India (UIDAI)?

A Unique Identification is merely a string assigned to an entity that identifies the entity uniquely.The Unique Identification Authority of India (UIDAI) plans to assign a Unique ID to every person residing in India. Biome-tric identification system and checks would be used to ensure that each individual is as-signed one and only UID and the process of generating a new UID would ensure that duplicates are not issued as valid UID numbers.
What is UIDAI?
The Unique Identification Authority of India (UIDAI) has been created, with the mandate of providing a unique identity to all Indian residents. The UIDAI has published an approach to pursuing this mandate, and plans to use biometrics to eliminate
duplicates and ensure uniqueness at enrolment. 
The AADHAR system is being designed to eventually service the entire population of India, and will involve the biometric identification of 1.2 billion residents. Since the estimated database size (1.2 Billion residents) is an order of magnitude larger than the current largest biometric database (115 Million), the biometric subsystem will have to be constantly monitored for accuracy, scalability and performance. To de-risk the entire program, the system will operate multiple concurrent solutions with the ability to introduce and test newer solutions.
Each Automated Biometric Identification Subsystem (ABIS) must implement an interface that is compliant with this specification. That de-couples the biometric subsystem from the main application logic, and enables a management layer that can orchestrate across the multiple solution providers, continuously measure accuracy, performance and enable better decision making. Initially, the same interface will be used for enrolment and authentication. At a later time, authentication may be moved out to a separate sub-system for better scaling, and replication. More generally, as the UID database grows in size, the requirements of the biometric system may evolve, and implementers of this interface will have to keep up with them.
