Secure input via a touchscreen

A method and apparatus is provided for securely obtaining input from a touchscreen. A secure execution environment may be implemented (e.g., at a processor), where the secure execution environment may include a touchscreen driver. A keypad image may be sent from the secure execution environment to be displayed by a touchscreen. An input location may be received at the secure execution environment from the touchscreen driver. Such input location may be converted at the secure execution environment into a character, symbol, or a request to change the keypad image displayed at the touchscreen. In one implementation, the secure execution environment may further implement a display driver which sends the keypad image to the touchscreen. The secure execution environment may implement driver keypad image mapping function that maps the keypad image to a character set.
