Abstract: Embodiments of this application provide an information processing method and apparatus. Trusted execution environments (TEEs) that can execute a procedure of processing a display request to obtain a display result are deployed in a terminal device. In this way, when the terminal device obtains a first display request through a first TEE, and the first display request includes display information of a first interface, the terminal device can draw the first interface through a first trusted user interface (TUI) framework in the first TEE. Therefore, a procedure of processing the first display request is implemented. A TUI display driver is integrated in a second TEE, and thus, the terminal device can call the TUI display driver of the second TEE to display the first interface. As a result, security of obtaining a display result by the terminal device is improved.
