Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If centralized authentication systems use usernames and passwords, then ease of operation is improved, but security reliability deteriorates due to single points of failure and unauthorized access risks
Solution Approach 1:
The patent segments authentication credentials into multiple independent components: biometric data stored locally on user devices, cryptographic keys distributed across blockchain nodes, and access tokens generated through smart contracts. This segmentation eliminates single points of failure by ensuring that no single component contains all authentication information, thereby improving security reliability while maintaining ease of operation through automated multi-factor verification.
Solution Approach 2:
The patent introduces blockchain as an intermediary layer between users and confidential information. The blockchain network mediates authentication by verifying biometric data against stored templates and managing access permissions through smart contracts. This intermediary mechanism enhances security reliability by providing decentralized verification without requiring users to directly manage complex cryptographic keys, thus maintaining ease of operation.
2Reliability
If biometric data is stored locally on user devices, then security reliability is improved by eliminating centralized points of failure, but device complexity increases
Solution Approach 1:
The patent implements self-service authentication where user devices automatically perform biometric verification against locally stored templates without requiring manual intervention. The device's biometric sensor and processing unit work autonomously to verify user identity, then interact with the blockchain network to obtain access tokens. This self-service approach improves security reliability through decentralized storage while managing device complexity by automating the authentication process rather than requiring users to manually configure cryptographic systems.
Solution Approach 2:
The patent designs the user device to perform multiple functions: storing biometric templates, capturing and processing biometric data, generating cryptographic keys, and communicating with the blockchain network. By consolidating these functions into a single multi-functional device, the system improves security reliability through local storage while minimizing the increase in perceived device complexity, as users interact with a unified interface rather than separate components.
3Reliability
If blockchain technology is used for decentralized authentication, then security reliability is improved, but device complexity and processing time increase
Solution Approach 1:
The patent implements preliminary action by pre-storing biometric templates on the blockchain network during user registration, before actual authentication is needed. When authentication occurs, the system compares captured biometric data against these pre-stored templates rather than generating and verifying cryptographic proofs from scratch. This preliminary preparation significantly reduces authentication time while maintaining the security reliability benefits of blockchain-based decentralized verification.
Solution Approach 2:
The patent applies local quality by performing computationally intensive biometric matching operations locally on user devices rather than requiring all verification to occur on the blockchain network. The device compares captured biometric data against locally stored templates and only submits verification results to the blockchain. This distribution of processing workload reduces authentication time while maintaining security reliability through the combination of local speed and decentralized verification.
4Ease of operation
If smart contracts automate access management, then ease of operation is improved by reducing manual intervention, but device complexity increases
Solution Approach 1:
The patent implements self-service access management through smart contracts that automatically verify user credentials and grant or deny access without manual intervention. The smart contracts on the blockchain autonomously execute authentication logic by verifying biometric data against stored templates and enforcing access permissions based on user roles and policies. This automation improves ease of operation by eliminating manual access management while managing device complexity by encapsulating the complex logic within the blockchain's smart contract environment rather than requiring it in user devices.
Data Source
AI summary
A system for authenticating a sender of a response to an authentication request includes an authentication server, an identity server configured to receive biometric data of a user, a central ID system configured to create or receive a username and/or password, and a first user device associated with a first user. The first user device is configured to create a first user ID that includes at least a first username and a first biometric data. When an authentication request is sent to a user device by the authentication server the user device responds with a user ID. The authentication server then queries at least one or both of the central ID system and the identity server to certify the accuracy of the user ID to assure it matches the first user ID before (1) accepting the response, or (2) permitting the first user to access confidential information. The systems and methods may also include blockchain authentication or tuple space authentication.
