Abstract
A method and apparatus for secure information input and output is described. The method may include initiating a secure data input mode at a user input device coupled with a computing system, wherein the computing system has a processor for executing an operating system, and the user input device is a peripheral input device for receiving input into the computing system. The method may also include receiving user inputted data at the user input device. The method may also include encrypting the user inputted data within the physical bounds of the user input device prior to transmission of the user inputted data from the user input device to the computing system. The method may also include transmitting the encrypted user inputted data to the computing system for routing to a trusted application, the encrypted user inputted data to remain hidden from an operating system of the computing system.
