In order to solve concerns about processes performed on a display screen for an authentication program which limits access to each file, the authentication program has an authentication process to request authentication of each file at the time of using the files. The authentication process controls a computer to execute operations of analyzing the authentication character-string input for the file name, determining whether the result of analysis is right or wrong, and opening and closing the file to enable use of the file when the result of analysis is right and to disable use of the file when the analysis result is wrong.
