The invention discloses an internetwork file self-service import system and an internetwork file self-service import method. The system comprises a shell, an intranet machine touch display module, animage acquisition module, an IC card reading module, a fingerprint identification module, an intermediate machine touch display module, a non-secret import module, a secret-related import module, a one-way import module, an intermediate machine control module, an intranet machine control module, a one-way isolation module and an optocoupler isolation control module. Compared with a manual guardingcentralized import mode, a self-service import use mode is adopted, and compared with a manual guarding centralized import mode, a file import link needing to be manually processed is automatically processed, so that the method is convenient and easy to use, the file import speed is greatly increased, and the service timeliness requirement is met.
