A dongle-based software copy protection method is disclosed. Protected software sends an invoking instruction to a dongle and goes on operating threads based on codes in the protected software. The dongle performs processing according to the invoking instruction, obtains a processing result and goes on operating threads based on codes in the dongle. The dongle sends the processing result to the protected software when necessary. A dongle-based software copy protection system and a dongle are also disclosed.
