More Information
Summary:A data security verification method and an electronic apparatus are provided. In the data security verification method, when the electronic apparatus is powered on, a verification circuit verifies integrity of an executable image in a storage device. If verification fails, the verification circuit stops a host processor from executing the executable image. If the verification is successful, the verification circuit releases a host reset, and a processor reads and executes the executable image. When the processor reads the executable image, the verification circuit re-verifies the executable image, and the processor executes the executable image according to a verification result.
