Ephemeral Network Generation for Vehicle Infotainment Data Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle infotainment systems pose data security risks by retaining personal information from users, especially in shared or rental vehicles, which can be accessed by unauthorized parties, violating data privacy regulations.
Innovation Solution
A computer-implemented method and system for generating ephemeral networks that connect computing devices based on user-specific events, establishing trusted connections for data sharing on a time-based basis using blockchain protocols, ensuring data is removed once the context of use is terminated.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If infotainment systems store user data for future access and personalization, then user convenience and service personalization are improved, but data security risks and privacy violations increase
Solution Approach 1:
The patent implements dynamic data retention where the infotainment system automatically adjusts data storage duration based on contextual factors such as vehicle ownership status, user preferences, and session type. Data is retained during active use for convenience but automatically deleted when contextual conditions change (e.g., vehicle returned, session ended), resolving the contradiction between convenience and security through time-based dynamic management
Solution Approach 2:
The system changes the retention parameter of user data from static (permanent storage) to dynamic (time-limited storage). By implementing automatic deletion mechanisms triggered by contextual events (vehicle return, session completion, user preference changes), the system maintains data availability during use while eliminating security risks after use, thus resolving the contradiction
2Adaptability or versatility
If infotainment systems retain personal information for service continuity, then service personalization is improved, but compliance with data protection regulations deteriorates
Solution Approach 1:
The patent implements periodic data deletion cycles triggered by contextual events such as vehicle return, session completion, or scheduled intervals. The system automatically deletes personal information after predetermined periods or events, ensuring continuous compliance with data protection regulations while maintaining service personalization during active periods through controlled data retention
Solution Approach 2:
The system incorporates feedback mechanisms that monitor contextual conditions (vehicle ownership status, user preferences, regulatory requirements) and automatically adjust data retention policies. When feedback indicates compliance risks (e.g., vehicle returned, maximum retention period reached), the system triggers data deletion to maintain regulatory compliance while preserving personalization capabilities during compliant periods
3Loss of information
If data is stored longer for potential future use, then data utility is improved, but exposure to unauthorized access increases
Solution Approach 1:
The patent implements preliminary determination of data retention duration based on predicted contextual needs. The system proactively deletes data before the end of its useful period based on predicted events (e.g., scheduled vehicle return, expected session end), ensuring data is available when needed while minimizing exposure time to unauthorized access through advance planning and automated execution
Data Source
AI summary
A method, system, and computer program product for contextual generation of an ephemeral network are provided. The method detects an initiating event for network generation associated with a user of a first computing device. The method determines a duration of the initiating event. A set of network members is determined based on the initiating event and the duration. The method establishes an ephemeral network, connecting at least a portion of computing devices associated with the set of network members. The ephemeral network is terminated in response to detecting a completion event. In response to terminating the ephemeral network, member information for the set of network members is removed from the portion of the computing devices.
