Abstract: A system and method of automatic access and control management of databases within a system includes a data management computer system and interconnected local computer systems. An accessing system requests information from a target system by data management system. The database management determines whether or not the information request satisfies a predetermined shared information access stored in a lookup table. The data management system verifies the transmitted information by comparing it to the rule and redacts information if necessary and transmits the verified information to the accessing local computer system. The data management system rejects the information access request if determined that the predetermined rule is not satisfied. The data management system determines whether to update the predetermined rule if access is nondeterminable, and automatically updates the rule. The accessing computer system uses the verified information.
