| Abstract;In order to allow any users to employ our system, we devised a new authentication system based on randomized questions which are answered only by the users in advance. And we evaluated the degree of accuracy and security and operability of the system. In the system, users must prepare beforehand the answer to the questions reflecting their own specific experience, such as the memory based on their private past history and so on. The system does not require any special hardware nor software to be implemented. The result of evaluation showed obvious superiority of the level of accuracy, security, operability and even robustics over conventional password method. The response time of the authentication system depended on the data transfer speed from the server to the client machines. From the results of our study, we could reconfirm that our proposed method could realize accurate and effective authentication even though users had to prepare their own questions and answers beforehand.
