Abstract

The present invention provides a user interface display method for a terminal, and a terminal, and the method includes: generating, by a terminal in a first operating environment, a first user interface that includes a first input component, obtaining a first user interface picture according to the first user interface, and determining attribute information of the first input component according to a first application; and switching, by the terminal, to a second operating environment, and displaying a second user interface in the second operating environment according to the first user interface picture and the attribute information of the first input component, thereby reducing processing overheads of the terminal.

Description

Technical field [0001] The present invention relates to communication technology, and in particular to a terminal interface display method and terminal. Background technique [0002] At present, the switching between different applications on the terminal is basically a seamless switch, which is only an interface (Activity), which also provides an opportunity for malicious applications to hijack the current foreground Activity, that is, the malicious application detects the target application process When enabled, switch to the foreground and cover the target application interface with a fake interface. In order to protect the user’s account security in login and transaction scenarios and prevent Activity hijacking, it is necessary to use the Trusted User Interface (TUI) under the Trusted Execution Environment (TEE). Deploy a set of trusted operating systems (Trusted OS) to improve the overall security of mobile smart terminals. The mobile smart terminal deployed with TEE is di...
