In-Vehicle Infotainment Login via Eigenvalue ID and TSP
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing in-vehicle infotainment systems face challenges in securely and efficiently logging users into multiple applications after unlocking the vehicle, leading to increased user frustration and security risks due to the need for manual login processes and storage of sensitive information.
Innovation Solution
The proposed method involves an in-vehicle infotainment application login system that uses eigenvalue IDs and temporary authorization codes to enable unconscious login after vehicle unlocking. This system communicates with a Telematics Service Provider (TSP) platform to verify eigenvalue IDs and authorization codes, ensuring secure and automatic login without caching user accounts or passwords within the infotainment system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If user account and password are stored in the in-vehicle infotainment for login, then login convenience is improved, but security risk increases due to potential account leakage
Solution Approach 1:
The patent extracts the sensitive user account and password information from the in-vehicle infotainment system. Instead of storing these credentials locally, the system uses a key-value storage mechanism that only stores encrypted eigenvalue IDs and temporary authorization codes, while the actual user account information is kept on the remote TSP platform, thereby eliminating the security risk of local credential storage while maintaining login convenience
Solution Approach 2:
The patent introduces an intermediary mechanism using eigenvalue IDs and temporary authorization codes as mediators between the user's unlocking medium and the user account. The in-vehicle infotainment system obtains the eigenvalue ID from the unlocking medium, requests the corresponding temporary authorization code from the TSP platform, and uses this code to perform login without directly accessing or storing the user's actual account credentials, thus securing the system while enabling automatic login
2Reliability
If manual login process is required for each application, then account security is maintained, but user experience deteriorates due to increased login steps
Solution Approach 1:
The patent implements preliminary action by pre-establishing binding relationships between multiple unlocking media and user accounts on the TSP platform before the user needs to access applications. When the user unlocks the vehicle with a specific medium, the system automatically retrieves the pre-bound temporary authorization code and performs login without requiring manual intervention, thus maintaining security while dramatically improving user experience
Solution Approach 2:
The system performs self-service by automatically completing the login process without user intervention. After the user unlocks the vehicle, the in-vehicle infotainment system automatically obtains the eigenvalue ID, requests the temporary authorization code from the TSP platform, verifies the code, and executes the login to the infotainment application all without requiring the user to manually enter credentials or confirm login, thereby maintaining security while eliminating manual login steps

AI summary
An in-vehicle infotainment application login method, apparatus/device, and system are involved, which relate to the field of automobile technologies. The method is applied to an in-vehicle infotainment, and includes: obtaining, by the in-vehicle infotainment, a first eigenvalue identity (ID) of a first medium after a user unlocks a vehicle through the first medium; sending a vehicle ID of the vehicle to a TSP platform, so that the TSP platform sends a target eigenvalue list to the in-vehicle infotainment based on the vehicle ID, the target eigenvalue list including a plurality of eigenvalue IDs bound to the vehicle and a temporary authorization code corresponding to each of the plurality of eigenvalue IDs; further, by the in-vehicle infotainment, obtaining the target eigenvalue list sent by the TSP platform, and determining a first temporary authorization code, the first temporary authorization code being a temporary authorization code corresponding to the first eigenvalue ID.
