Image forming apparatus and control method thereof

Abstract

The invention relates to an image forming device and a control method thereof, the image forming device comprises an imaging processing module, a trusted computing supervision module and a memory, and the imaging processing module is used for controlling the imaging processing operation of the image forming device; the trusted computing supervision module is used for monitoring operation activities corresponding to the imaging processing module in the image forming device; the trusted computing supervision module is also used for collecting a standard power consumption threshold range of a hardware module in the imaging processing module, and the memory is used for storing the standard power consumption threshold range and a predetermined management and control strategy; the trusted computing supervision module also obtains the real-time power consumption of a hardware module in the imaging processing module by monitoring the corresponding operation activity of the imaging processing module, and compares the real-time power consumption with a standard power consumption threshold range to generate a comparison result; the trusted computing supervision module also controls the imaging processing module based on the comparison result and a predetermined control strategy.

Description

technical field [0001] The present invention relates to the technical field of image forming, in particular to an image forming device and a control method thereof. Background technique [0002] With the advancement of electronic science and technology, the development of image forming apparatus (Image forming apparatus) has become more and more mature. However, as a kind of computer peripheral equipment, image forming apparatus is vulnerable to attacks by criminals (such as hackers). and / or fax-enabled laser printers (one of many types of image forming devices) as an example, the scanned or faxed data may carry the user’s confidential data, and even the photosensitive drum, which is the core component of laser imaging, is also It may carry confidential data to be printed by the user; once the data is leaked, it will bring a lot of unnecessary trouble to the user. [0003] The image forming device has a variety of imaging processing modules, such as scanning, printing, copy...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the problem of illegal use of the imaging processing module in the existing image forming device, this application proposes an image forming device with a trusted computing supervision module, which has a higher priority than the system on chip SoC of the image forming device level, and will not affect the system scheduling resources and normal operation process of the imaging processing module. The trusted computing supervision module monitors the operation of each imaging processing module by monitoring the power consumption of the imaging processing module at each stage of the image forming device operation prevent illegal use of the imaging processing module in the image forming device, making the control of the image forming device safer and more controllable
