ELECTRONIC APPARATUS, PERIPHERAL DEVICE, AND SYSTEM FOR ENCRYPTING AND DECRYPTING THE ELECTRONIC APPARATUS VIA THE PERIPHERAL DEVICE

摘要

An electronic apparatus, a peripheral device, and a system for encrypting and decrypting the electronic apparatus via the peripheral device are provided. The electronic apparatus stores a password which a user sets in a ROM of the electronic apparatus and writes the password to the peripheral device. Only when the electronic apparatus is connected to the peripheral device, the electronic apparatus fetches a password from the peripheral device, and if the electronic apparatus determines that the fetches password is the same as the stored password in the electronic apparatus, the electronic apparatus performs a function of turning on or unlocking the electronic apparatus.
