South African Home Affairs is charged with maintaining natural security by regulating citizenship, residence, migration and asylum seekers. Effective fulfillment of this function requires accurate data base from strategic sources which is regularly updated. This data should provide information which can be mined for extended value not only for the prevention and management of crime, but also for socio economic development. Apart from internal affairs this departmental function is closely tied to International legal instruments to which South Africa is a signatory. The Department of Home Affairs makes extensive use of the services of Sondolo IT, which provides a valuable resource of data mining essential for maintaining national security. This is achieved through a sophisticated biometrics system, systems and technical services, information networking, software integration services, people tracking surveillance and access control.
