IMAGING DEVICE, SECURE IMAGING METHOD THEREOF AND IMAGING SYSTEM

摘要

An imaging device, a secure imaging method thereof and an imaging system. The method comprises: generating a password based on an event triggered by a user and presenting the password to the user; receiving a first random number and an encrypted to-be-printed file sent by a computing device connected to the imaging device; based on the password and the first random number, using a first specified algorithm to generate a key; using the key to decrypt the encrypted to-be-printed file based on a second specified algorithm to obtain a decrypted to-be-printed file; and printing out the decrypted to-be-printed file. Not only does a printed file become more secure in a transmission process but also a manufacturing cost of an imaging apparatus is reduced to an extent.
