Abstract
A computer system requiring input of a password on startup has an on-screen keyboard generation division for displaying an on-screen keyboard having a predetermined key layout on a touch panel, a keyboard type determination division for determining the key layout of the on-screen keyboard displayed on this touch panel, and a password checking division for processing a password inputted by pointing to the on-screen keyboard displayed on this touch panel. The key layout displayed on the touch panel is determined by a user pressing a particular key on a mechanical keyboard, which identifies which layout is to be displayed on the touch panel.
