Solution Overview

Problem

Modern vehicles lack systems for controlling access to sensors by third-party applications, relying on static preferences or user-configured settings, which do not account for the context of vehicle operations and user privacy needs.

Innovation Solution

A context-aware fine-grained device access control system that monitors vehicle operating characteristics and user inputs to dynamically regulate access requests from applications, using an access control model to grant or deny access based on vehicle context and user preferences, updating the model based on user interactions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If third-party applications are allowed to access vehicle sensors without control systems, then application functionality and versatility are improved, but personal data security and privacy protection deteriorate

Engineering Contradiction:
Improveapplication functionalityVSAvoidpersonal data security
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces an access control system as an intermediary between third-party applications and vehicle sensors. This mediator evaluates access requests by analyzing application identifiers, requested sensor types, vehicle operating characteristics, and user preferences before granting or denying access. The intermediary layer enables applications to function while protecting personal data through controlled, monitored access rather than direct unrestricted connection.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The access control system dynamically adjusts access permissions based on real-time vehicle operating characteristics such as location, speed, and environmental conditions. Rather than static access rules, the system adapts its control decisions based on current context, allowing applications to access sensors only when appropriate conditions are met, thus balancing functionality with security in a dynamic manner.

Inventive Principle:
Principle #15Dynamics

2Device complexity

If static user preferences are used for access control, then system simplicity is maintained, but adaptability to different operating contexts and user needs deteriorates

Engineering Contradiction:
Improvesystem simplicityVSAvoidcontext awareness
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The system performs preliminary actions by pre-configuring user preferences and access control policies before actual access requests occur. Users can set their preferred access levels and conditions in advance, and the system uses these pre-established rules as a baseline for evaluating real-time access requests, combining simplicity of pre-set preferences with adaptability through contextual evaluation.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The access control system changes operational parameters based on vehicle operating characteristics such as location, speed, and environmental conditions. When access requests are received, the system modifies its evaluation criteria by considering current contextual parameters, allowing the same access control mechanism to adapt its behavior based on changing vehicle states while maintaining a unified system architecture.

Inventive Principle:
Principle #35Parameter changes

3Object-affected harmful factors

If comprehensive access monitoring and control is implemented, then personal data protection is improved, but processing time and computational resources required deteriorate

Engineering Contradiction:
Improvepersonal data protectionVSAvoidaccess request processing time
Core Design Contradiction:
Object-affected harmful factorsVSLoss of time

Solution Approach 1:

The access control system segments the access evaluation process into distinct analytical components: application identifier verification, sensor type validation, operating characteristic assessment, and user preference matching. By dividing the comprehensive security check into separate processing stages, the system can efficiently evaluate each aspect independently and make faster overall decisions while maintaining thorough protection.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system implements feedback mechanisms where access decisions and their outcomes are recorded and analyzed. This feedback information is used to refine future access control decisions, allowing the system to learn from previous evaluations and make more efficient, accurate decisions in the future, reducing processing time while maintaining high security standards.

Inventive Principle:
Principle #23Feedback

AI summary

Context-aware fine-grained device access control for a vehicle is provided. Aspects include receiving an access request from an application installed on the vehicle, obtaining one or more operating characteristics of the vehicle, and inputting the access request and the one or more operating characteristics of the vehicle into an access control model. Aspects also include granting the access request to the application based on one of receiving a grant access request from the access control model and receiving an approval of the access request from the operator of the vehicle. Based on one of receiving a deny access request from the access control model and receiving the denial of the access request from the operator of the vehicle, aspects include denying the access request to the application. The access request includes an identifier of the application and an identifier of a type of access being requested by the application.
