Digital Car Key Registration With Vehicle-Bound User Identity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing digital car key registration methods rely on a fixed hash value of the user account identity, which can lead to personal data leakage as vehicle manufacturers can associate multiple car purchases or changes with the user, compromising user privacy.
Innovation Solution
A digital car key registration method where the user identity is generated based on a combination of the car owner account identity and car information, such as car identity and brand, to create a unique user identity that is not solely based on the user account identity, thereby preventing data leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a fixed hash value of user account identity is used for digital car key registration, then the registration process is simple and efficient, but user privacy is compromised as vehicle manufacturers can associate multiple car purchases or changes with the user
Solution Approach 1:
The user identity is segmented into multiple components: a fixed hash value of the user account identity and a variable car information element. This segmentation allows the system to maintain registration efficiency while preventing complete user identification, as the variable element changes with each car registration breaking the direct association between user and vehicle manufacturer
Solution Approach 2:
The patent adds a new dimension to the identity structure by incorporating car information (such as vehicle identification numbers) into the user identity generation process. This transforms the identity from a single-dimension fixed hash to a multi-dimensional composite identifier, enabling privacy protection while maintaining functional recognition
2Object-affected harmful factors
If user identity is generated based on user account identity and car information, then user privacy is protected, but the complexity of the registration process increases
Solution Approach 1:
The terminal device automatically generates the user identity by combining the hash value of the user account identity with car information, without requiring manual intervention from the user. This self-service approach maintains simplicity from the user perspective while implementing the complex privacy-protective identity structure in the background

AI summary
A digital car key registration method, performed by a terminal and includes: sending, to a server, a registration request for requesting the registration of a digital car key, where the registration request includes a user identity of the digital car key, and the user identity is generated on the basis of a car owner account identity and car information.
