DATA MANAGEMENT METHOD, PROGRAM THEREOF, AND PROGRAM RECORDING MEDIUM

摘要

Recording is restricted when user data or a program stored in an electronic computer is going to be carried to the outside by being recorded to an electronic recording medium with a recording device connected to the computer. A data management program stored in the computer has the function of restricting writing of data to the recording medium from the computer so that only a user authenticated by user authentication is enabled to perform the writing. The data management program authenticates whether or not the user is an authorized one by using a USB memory storing a secret key for authentication.
