Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data is collected from entitled members for ADAS and AV systems, then the system can perform object detection and autonomous navigation, but data security and privacy are compromised
Solution Approach 1:
The patent introduces an intermediary authentication mechanism that verifies data from entitled members without revealing their identities. The system uses authentication credentials and digital signatures as intermediaries to validate data provenance while maintaining sender anonymity, thus resolving the contradiction between data security verification and privacy protection.
Solution Approach 2:
The patent creates cryptographic copies (digital signatures and authentication tokens) of the entitled members' credentials without exposing the original sensitive information. These cryptographic copies enable verification of data authenticity while preserving the privacy of the source members, allowing the system to verify data security without compromising privacy.
2Loss of information
If anonymous data collection is implemented, then privacy is protected, but verification of entitled member status becomes difficult
Solution Approach 1:
The patent replaces traditional mechanical authentication systems (which rely on identifiable credentials) with cryptographic authentication mechanisms. Digital signatures and homomorphic hash functions substitute for conventional identity verification methods, enabling anonymous yet verifiable authentication that protects privacy while maintaining security verification capabilities.
Solution Approach 2:
The patent transforms authentication parameters from identifiable information to cryptographic representations. By changing the parameter space from direct identity verification to cryptographic proof verification, the system enables anonymous authentication where the difficulty of verification is reduced through mathematical properties of cryptographic functions rather than complex identity checking.
3Device complexity
If traditional data collection methods are used, then data processing is simple, but data security and authenticity cannot be verified
Solution Approach 1:
The patent applies preliminary authentication actions by embedding digital signatures and authentication credentials with the data before collection. This preliminary cryptographic processing ensures that data authenticity can be verified later without requiring complex real-time authentication mechanisms, thus maintaining relatively simple processing while ensuring reliability.
Solution Approach 2:
The patent introduces cryptographic intermediaries (digital signatures, authentication tokens, homomorphic hashes) that mediate between simple data collection and complex authenticity verification. These intermediaries carry verification information that enables reliable authentication without requiring the collecting system to implement complex verification logic, thus maintaining processing simplicity while ensuring data authenticity.

AI summary
A method for collecting data from a group of entitled members. The method may include receiving, by a collection unit, a message and a message signature; validating, by the collection unit, whether the message was received from any of the entitled members of the group, without identifying the entitled member that sent the message; wherein the validating comprises applying a second plurality of mathematical operations on a first group of secrets, a second group of secrets, and a first part of the message signature; and rejecting, by the collection unit, the message when validating that the message was not received from any entitled member of the group.
