DATA MANAGEMENT METHOD, PROGRAM THEREOF, AND PROGRAM RECORDING MEDIUM

摘要

When user data and a program stored in a computer is recorded into an electronic recording medium by a recording device connected to the computer and carried outside, its recording is limited. The data management program stored in a computer has a function used when writing data from the computer onto the recording medium, for authenticating a user and disabling a person other than the authorized person to perform writing. The data management program authenticates whether the user is an authorized person by using a USB memory containing a secret key for authentication.
