File storage and access method allowing storage equipment to accept user's validation directly

The invention relates to an information safety protecting method and discloses a file storage and access method allowing storage equipment to accept user's validation directly. The method is based on mobile storage equipment comprising a control chip and a storage device inside, special file transfer software managing the mobile storage equipment and a hardware platform used for interacting with a user and operating the special file transfer software; According to the method, the access authority of the hardware platform is controlled in the operation range for each time, data stealing is prevented effectively after the access authority is released, an input component allowing a user to use is arranged additionally, the user can input the validation information into the mobile storage equipment directly, file access authorization can be operated in a processing chip independent to the hardware platform, Trojans and other viruses are prevented from controlling the hardware platform to operate automatically, and the confidentiality of the storage device is improved greatly.
