A novel computer security system for preventing unauthorized users, children for example, from accessing both a personal computer and Internet web sites, comprising: 1) a smart card containing a user's information; 2) a keyboard which read the user's information from the card and compares it with registered user information; and 3) a central server, located at a separate remote site, which identifies the user's information and controls access to web sites.
