Abstract
Mobile terminal having virus resistant security module architecture. An embedded security module can control the presentation of information on a display by controlling access to display memory. In some embodiments, the security module is also provided with an interface to enable it to handle user input function as well. In this way, the presentation of transaction information and receipt of user input can be substantially isolated from the main, control microprocessor of the terminal for enhanced security, especially protection against resident viruses. In addition, the security module can copy display data into the authentication and/or authorization message that is returned by the terminal to the base station. The return of the display data provides an extra, secure confirmation of the transaction.
