A METHOD AND SYSTEM FOR MANAGING CONFIDENTIAL INFORMATION

摘要

A method and a system for information management and control is presented, based on modular and abstract description of the information. Identifiers are used to identify features of interest in the information and information use policies are assigned directly or indirectly on the basis of the identifiers, allowing for flexible and efficient policy management and enforcement, in that a policy can be defined with a direct relationship to the actual information content of digital data items. Further the method and system provides for the use of a compound object (110), which has three single information objects (120, 122 and 124). The information object can be of various kinds. The system can provide protection against information policy breaches such as information misuse, unauthorized distribution and leakage, and for information tracking.
