Abstract: A data input method and apparatus, and user equipment are provided. The method includes: when it is determined that an operation of a user on the user equipment UE is not performed in a preset display area, deliver an event corresponding to the operation to a first operating environment for processing, where the preset display area runs in a second operating environment of the UE, and the second operating environment has a higher security level than the first operating environment. This can better improve security of an event generated when the user operates a program that runs in a Normal World of the user equipment, and can directly operate an event that runs in the Normal World.

Abstract: Embodiments of this application provide an information processing method, and relate to the field of information and communication technologies. An electronic device includes a first memory and a second memory. When loading application information, the electronic device obtains an attribute of the application information; if the attribute of the application information is a first attribute, writes the application information into the first memory, or encrypts the application information and writes the encrypted application information into the second memory, where the first memory is disposed in a processor, and the second memory is disposed independently of the processor; and if the attribute of the application information is a second attribute, writes the application information into the second memory. Embodiments of this application further provide an electronic device, a chip, and a computer-readable storage medium.
