    • 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.
    • 机密信息的泄漏防范系统,例如CBT(计算机辅助培训),防止高度机密的教育和培训信息泄露。 该系统包括具有认证服务器的管理终端单元,用于以加密形式保存加密形式的机密信息并由特定用户操作的教育者/培训者终端单元和用于在这些终端单元之间进行数据交换的通信网络 。 只有当教育者/培训者终端单元的认证请求满足预定的认证授权要求时才向教育者/培训者终端单元进行认证,并且设定规定的有限使用时间,以便可以将解密的机密信息 教育/培训机构终端单位,只在有限的时间内。
