Automated Driving Feature Subscriptions Via Private-Public Blockchains
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing blockchain-based subscription management of ADS features in vehicles is complex and costly, involving multiple actors and requiring significant backend interactions, which complicates identity protection and compliance with regulations like GDPR.
Innovation Solution
A subscription management system utilizing a private blockchain network for private data handling and a public blockchain network for NFT-based subscription management, enabling community-based subscription handling with smart contracts to manage ADS feature activations and deactivations efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a centralized subscription management system is used for ADS features, then control and transparency of the process can be maintained, but process complexity and transaction costs increase significantly
Solution Approach 1:
The patent segments the subscription management process into multiple independent smart contracts deployed on a blockchain network. Each smart contract handles specific functions (subscription creation, validation, activation, billing), distributing the control logic across the network rather than centralizing it in a single system. This segmentation maintains transparency through immutable recording while reducing the complexity burden on any single component.
Solution Approach 2:
The patent introduces a blockchain network as an intermediary layer between the ADS feature provider, customer, and vehicle fleet OEM. This intermediary enables automated verification and coordination through smart contracts, eliminating the need for complex direct interactions and handovers between parties. The blockchain mediator maintains transparency while simplifying the overall process architecture.
2Reliability
If multiple actors and handovers are involved in subscription activation, then comprehensive validation can be performed, but transaction costs and process complexity increase
Solution Approach 1:
The patent implements self-service mechanisms where the blockchain network and smart contracts automatically perform validation, verification, and coordination tasks that would otherwise require manual intervention from multiple actors. The system validates subscription eligibility, vehicle compatibility, and payment status automatically through programmed logic, eliminating the need for extensive human-to-human handovers and reducing transaction costs.
Solution Approach 2:
The patent performs preliminary validation and setup actions through smart contracts before the actual subscription activation occurs. Eligibility criteria, vehicle requirements, and billing terms are pre-programmed and verified in advance, allowing the subscription activation to proceed automatically without requiring multiple sequential handovers and validations during the execution phase.
3Productivity
If customer identity information is shared across multiple parties, then subscription activation can be processed, but privacy protection and GDPR compliance become challenging
Solution Approach 1:
The patent extracts sensitive customer identity information from the main subscription processing flow and stores it separately in encrypted form on the blockchain. Only necessary validation data is shared with vehicle fleet OEMs, while full identity details remain protected. This extraction approach enables subscription processing to proceed efficiently with minimal data exposure, maintaining GDPR compliance by limiting data sharing to what is strictly necessary.
Solution Approach 2:
The patent applies different data protection qualities to different parts of the system. Sensitive personal information is encrypted and stored with restricted access, while only anonymized or minimized data elements are shared across the network for validation purposes. This local quality approach allows efficient processing where needed while maintaining strong privacy protection where required, balancing productivity with compliance.

AI summary
The present disclosure relates to a method performed by a subscription management system (1) for provision of a subscription service for ADS features. The subscription management system deploys (1002) on a private blockchain network (3) comprising a set of nodes (31), a smart contract identifying data indicative of a user (4) being eligible for one or more subscription options representing various ADS feature sets, the user-indicative data comprising a respective unique private key (41) and public key (42) personal to the user (4); deploys (1005) on a public blockchain network (7) supporting minting of NFTs, and for instance comprising at least one of said set of nodes, a smart contract generating a whitelisting request transaction comprising the unique private and public keys; deploys (1006) a smart contract adding the whitelisting request transaction to the public blockchain, the addition whitelisting the unique public key for minting of NFTs on the public blockchain network; deploys (1007) on the public blockchain network, a smart contract identifying data indicative of the public key having been included in minting of an NFT on the public blockchain, which NFT comprises and/or points to data indicative of an at least first subscription option out of the one or more subscription options and further comprises a unique address associated with the user derived from the unique public key; deploys (1008) on the private blockchain network, a smart contract generating a subscription activation transaction comprising data indicative of the unique address and comprising and/or pointing to the at least first subscription option; and deploys (1009) a smart contract adding the subscription activation transaction to the private blockchain, the addition whitelisting activation of the ADS feature set of the at least first subscription option. The disclosure also relates to a subscription management system in accordance with the foregoing, at least a first node comprising such a subscription management system, and a respective corresponding computer program product and non-volatile computer readable storage medium.
