Abstract

A storage apparatus includes a recording medium 40 on which a coded password XW.sub.1, generated by coding a password assigned to a user using a coding algorithm (one-way function) is recorded. A coding section produces a coded password XW.sub.2 by coding a password PW.sub.2 input by the user using the coding algorithm, and a checking section compares the coded passwords XW.sub.1 and XW.sub.2. An access control section permits access to the recording medium when the checking section judges that the passwords XW.sub.1 and XW.sub.2 match, while barring access when the passwords XW.sub.1 and XW.sub.2 do not match.
