Consumable Cartridge Chip Interference for Secure Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing consumable chips in printing apparatuses are vulnerable to confidential data leakage as they passively receive data and cannot prevent competitors from obtaining sensitive information during communication.
Innovation Solution
The consumable chip is equipped with an interference module that actively interferes with data transmission, altering the data on the communication bus to prevent unauthorized access and detection of confidential information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the consumable chip passively receives confidential data from the printing apparatus, then the data transmission is simple and straightforward, but the confidential data can be easily obtained by third parties through monitoring communication waveforms
Solution Approach 1:
The consumable chip applies preliminary anti-action by proactively generating interference signals during the downlink period to counteract the transmission of confidential data from the printing apparatus. The interference module detects when the printing apparatus transmits data and actively emits interference signals on the same communication bus, thereby preventing third parties from successfully capturing the confidential information before it can be transmitted.
2Reliability
If the consumable chip actively interferes with data transmission to prevent data leakage, then data security is improved, but the communication between host and chip may be affected
Solution Approach 1:
The interference module dynamically adjusts its operation based on the communication phase. It remains inactive during the uplink period when the chip needs to receive instructions, and activates during the downlink period when the printing apparatus transmits data. This dynamic switching ensures that interference is applied only when needed for security, while maintaining normal communication functionality during other phases.
Solution Approach 2:
The interference module employs feedback mechanisms to monitor the communication bus and detect when the printing apparatus is transmitting data. Based on this feedback, the module intelligently activates or deactivates the interference signal generation, ensuring that interference is applied only during downlink transmission periods when confidential data is being sent, thereby preserving communication integrity during uplink periods.

AI summary
Embodiments of the present disclosure provide a chip, a consumable cartridge, and a data transmission method. The chip is configured to communicate with a host and establish a communication connection with the host and receive first data transmitted from the host to the chip, where the chip interferes the first data during a downlink period of receiving the first data, such that second data received by the chip is different from the first data. In embodiments of the present disclosure, the chip is capable of interfering preset data transmitted by the host to the chip, which prevents a third party from obtaining confidential data transmitted by the host to the chip by a mean of detecting and collecting communication waveforms between the host and the chip.
