Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a secure central database model is used for authentication, then authentication security is improved, but system complexity and dependency on centralized infrastructure increase
Solution Approach 1:
The patent segments the authentication system into distributed components: authentication servers in different locations, multiple readers, and tags with embedded security elements. This segmentation eliminates the single point of failure in centralized databases while maintaining security through distributed verification of authentication data.
Solution Approach 2:
The patent introduces authentication servers as intermediaries between readers and tags. These servers store and verify authentication data without requiring a single centralized database, acting as mediators that enable secure offline authentication while distributing system complexity across multiple server nodes.
2Use of energy by moving object
If offline authentication is implemented without password protection or encryption, then resource requirements are reduced, but vulnerability to counterfeiting increases
Solution Approach 1:
The patent applies preliminary action by pre-loading authentication data and security credentials into tags and readers during manufacturing. This allows offline authentication to proceed without real-time encryption/decryption computations, reducing energy requirements while maintaining security through pre-established authentication mechanisms that are difficult to counterfeit.
Solution Approach 2:
The patent changes the security parameter from requiring active password protection and real-time encryption to using embedded authentication data with cryptographic signatures. This parameter change reduces computational energy requirements while maintaining anti-counterfeiting capabilities through hardware-embedded security elements that are difficult to replicate.
3Reliability
If encryption and password protection are applied in offline authentication, then security against counterfeiting is improved, but computational requirements and resource consumption increase
Solution Approach 1:
The patent performs encryption and security setup in advance during tag and reader manufacturing. Authentication data is pre-encrypted and stored in secure memory locations, eliminating the need for real-time cryptographic computations during offline authentication, thus reducing energy consumption while maintaining security.
Solution Approach 2:
The patent enables readers and tags to perform self-verification using embedded authentication data and cryptographic signatures. This self-service approach eliminates the need for continuous connection to authentication servers for verification, reducing computational energy requirements while maintaining security through locally-stored cryptographic credentials.
4Measurement precision
If centralized database access is required for authentication, then verification accuracy is improved, but loss of time due to network dependency increases
Solution Approach 1:
The patent segments authentication data into distributed authentication servers located in different geographic positions. Readers can access nearby servers for verification, reducing network latency and authentication time while maintaining verification accuracy through distributed copies of authentication data and cryptographic verification capabilities.
