ABSTRACT:
A leakage preventing system of confidential information, for example, for CBT (Computer Based Training), prevents leakage of highly confidential education and training information. The system includes a manager terminal unit having an authentication server, an educator/trainer terminal unit for holding confidential information for CBT in the encrypted form and operated by a specific user, and a communication network for exchanging from time to time data between these terminal units. Authentication is given to the educator/trainer terminal unit only when an authentication request from the educator/trainer terminal unit satisfies predetermined authentication granting requirements, and a prescribed limited using time is set so as to make it possible to peruse the confidential information decoded in the educator/trainer terminal unit, only within the limited time.
