Multi-portion Hardware Identifier for Print Device Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Print devices face issues with ensuring compatibility and quality of replaceable consumable components, as low-quality components can lead to reduced print quality and potential damage to the device, and existing authentication methods are vulnerable to counterfeiting.
Innovation Solution
A multi-portion hardware-based identifier is distributed across various consumable components, which is read and combined by the print device to verify authenticity, providing enhanced security and control over component usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single-portion identifier is used on consumable components, then the authentication system is simple to implement, but it is vulnerable to counterfeiting and cannot ensure component compatibility
Solution Approach 1:
The identifier is divided into multiple portions and distributed across different consumable components. Each portion alone is insufficient for authentication, but when combined, they form a complete identifier that verifies component authenticity and compatibility. This segmentation prevents counterfeiting while maintaining system reliability.
2Duration of action of stationary object
If consumable components are made replaceable to extend device lifespan, then device durability improves, but compatibility and quality control become difficult to maintain
Solution Approach 1:
The multi-portion identifier system is pre-configured on consumable components during manufacturing. Before the consumable components are installed in the print device, their identifiers are already in place, allowing the device to verify compatibility and authenticity in advance, ensuring quality control while enabling replacement.
3Reliability
If traditional authentication methods are used for consumable components, then the system is easy to operate, but it is susceptible to counterfeiting and cannot prevent quality defects
Solution Approach 1:
The multi-portion identifier acts as an intermediary verification mechanism between the consumable components and the print device. The sensor reads the distributed portions and the controller combines them to verify authenticity, providing a secure authentication process that remains transparent and easy to operate for users.

AI summary
In one example in accordance with the present disclosure, a print device is described. The print device includes multiple consumable components. Each consumable component includes a portion of a hardware-based identifier. At least one sensor of the print device reads multiple portions of the hardware-based identifier. A controller of the print device combines the multiple portions of the hardware-based identifier and verifies the hardware-based identifier to determine an authenticity of the multiple consumable components.
