Abstract: A trusted application running method applied to a computer system on which a trusted execution environment (TEE) and a rich execution environment (REE) are deployed, where one or more trusted applications (TAs) run on the TEE operating system. The TEE operating system may start a target TA. Then, the target TA may send, to the TEE operating system, a loading request for a target dynamic library supporting the target service. The TEE operating system may load the target dynamic library to memory space of the target TA in response to the loading request. In this way, before the target TA runs the target service, a program module used to support the target service does not need to be loaded to the memory space of the TA, thereby reducing a waste of the memory space of the TA.

Abstract: A two-dimensional code processing method and a device. The method includes: obtaining, by a first electronic device, two-dimensional code information displayed by a second electronic device; obtaining first scenario information, where the first scenario information is scenario information related to the first electronic device; determining two-dimensional code data and second scenario information based on the two-dimensional code information, where the second scenario information is scenario information related to the second electronic device; and when determining that the first scenario information and the second scenario information meet a preset condition, performing, by the first electronic device, preset processing on the two-dimensional code data. The scenario information of the two electronic devices that need to perform two-dimensional code interaction is compared, and further, two-dimensional code verification is completed.
