National intelligence grid — An information sharing grid

National Intelligence Grid (NATGRID) provides an information sharing platform between Intelligence Agencies and E-Governance organizations of India. NATGRID deals with the database integration of different Government, Quasi-Government as well as Private Organizations of Indian E-Governance. This paper focuses on design of a framework for integrating various E-governance organizations also called the departments and for providing the information access to 11 Indian Investigation agencies. For integrating of the databases the NATGRID uses Aadhaar ID, a 12-digit unique number issued to every Indian resident by the Unique Identification Authority of India (UIDAI). Based on their functionality, the intelligence agencies can access only the respective necessary databases. The administrator sets the privileges based on the interdependency of various departments and the functionalities of investigation agencies. The investigation agencies can share the information and interact with the other. This paper addresses the analysis and design of the NATGRID System. The necessary preliminary architectural design and implementation details are discussed.
