Method for encrypting consumable items through radio frequency identification electronic tag

Abstract

The invention provides a method for encrypting consumable items through a radio frequency identification electronic tag. By using a method of additionally arranging the radio frequency identification electronic tag on the consumable items of various devices and using the devices and the radio frequency identification electronic tag to communicate by a method for communicating through encryption information, the consumable items are encrypted and protected. The consumable items are encrypted by adopting the non-contact radio frequency identification electronic tag, so that the consumable itemsare not easy to rust and damage and the reliability is improved; the radio frequency identification electronic tag is initialized after the consumable items are assembled, thus the speed of initialization is greatly improved; the method is convenient to comply a plurality of groups of passwords and produce and manage and provides the possibility for complying different passwords according to different requirements; a module is packaged by using a physical method, so that all keys cannot be obtained by using a method of breaking a host program, and the stability for encryption is greatly improved; and by setting an automatic protecting function at the radio frequency identification electronic tag, the information security is ensured.

Description

technical field [0001] The invention relates to a method for protecting consumables, in particular to a method for protecting consumables with an anti-cracking function by encrypting consumables through radio frequency electronic tags. Background technique [0002] With the increasingly rich functions and higher precision of equipment, many equipment need to be replaced according to the usage conditions, such as printer ink cartridges, ribbons, drums and toner of color laser printers, transfer belts of label printers, etc. Such consumables, inkjet printers are common printing equipment, which provide great convenience for modern office. For example, most of the existing inkjet printers use detachable ink cartridges to load the ink used for printing. Many ink cartridge housings are equipped with chips, and the chips are provided with electronic modules and multiple contacts. Such as ink cartridge model, ink color, ink remaining data in the ink cartridge and other information...

AI Technical Summary

Problems solved by technology

[0005] 1. The chips on the consumables are all connected to the host by contact contacts. These contact contacts have the disadvantages of being easy to rust and damage, so that they cannot be effectively used when starting up, resetting or monitoring ink consumption in real time. Certify Consumables

[0006] 2. These chips are only simple data storage, which are easy to be cracked, so that the consumption of consumables can be rewritten arbitrarily, so that the use of consumables and the judgment of whether they are original consumables cannot be guaranteed, thus endangering normal operation of equipment

[0007] 3. These chips need to be written with corresponding data before they are installed in consumables. Therefore, different chips need to be prepared for different consumables during production, and the content of the chip controlled by the main board of the machine is easy to be cracked, and there is a serious security risk. question

[0008] Since the consumable itself is the key to the normal operation of the system, and the existing identification methods cannot protect the security of the information used, it is easy to use it beyond the expiration date due to user modification of the information, or use some counterfeit and inferior products, which will affect the normal operation of the equipment, so it is necessary A safe method that can identify the authenticity and usage status of consumables, thereby helping the host computer to judge the legitimacy of consumables (consumable parts), and further protect the operation of the entire system device
