Abstract: A data integrity protection method is applied to an electronic device, and the electronic device stores vendor data and first verification information. The first verification information is stored in a first storage area of the electronic device and is used to perform integrity verification on the vendor data. The method includes: First data is obtained. Digital signature is performed on the first data to generate second data and second verification information. The second data and the second verification information are stored, where the second verification information is stored in a second storage area of the electronic device. According to the data integrity protection method provided in this embodiment of this application, firmware or software customized by a third-party integrator is supported in being reloaded to a system for running, thereby simplifying a process and improving integrated development efficiency of an electronic device.
