The invention brings forward a verification method of a flash ROM (Read-only Memory Image) and a verification apparatus of a flash ROM. The verification method includes the steps: receiving a flash request from a target device connected to a terminal, wherein the flash request carries a flash ROM and the first digital signature value of target data in the flash ROM; obtaining the target data in the flash ROM; conducting preset operation on the target data to obtain a first operation result; and determining whether the first digital signature value is a digital signature value of the first operation result, and then determining whether verification of the flash ROM is successful on the basis of a determination result. According to the technical solution, the flash ROM is verified before flash, so people can ensure that flash of the terminal can be achieved only by a genuine flash ROM authenticated by a terminal manufacturer. Therefore, the flash quality of the terminal is improved, and the user experience is improved.
