Abstract
When transferred data is registered, it is determined whether access to the registered data is or is not protected by a password. If it is determined that a password is necessary, an inquiry is made to the registration request side, as to whether or not registration processing is to be continued. If a response of agreeing to the registration is received, registration processing is continued, while if a response of not agreeing to the registration is received, the registration processing is stopped. When a request of outputting registered data is received, it is determined whether or not password is necessary to output the registered data. If it is determined that password is necessary, password input is requested to an output request side. If a password inputted by the output request side is correct output processing is continued, while if the password is not correct, the output processing is stopped.
