EV Charging Authorization With Personal Data Deletion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle charging systems lack secure and efficient methods for handling personal information related to vehicles and their occupants, leading to potential privacy concerns and data misuse.
Innovation Solution
A method where a charging station determines a vehicle's request for approval, accesses and analyzes personal information, grants approval for charging, and subsequently deletes the information after the charge is received, utilizing blockchain technology for secure data management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the charging station accesses and stores personal information for authorization, then the charging process can be properly authorized and controlled, but the privacy security and risk of data misuse deteriorate
Solution Approach 1:
The system performs preliminary authorization by analyzing personal information before the charging process begins. The charging station accesses, verifies, and makes authorization decisions based on personal information in advance, then deletes the information immediately after authorization is granted, eliminating the need to store sensitive data during charging.
Solution Approach 2:
The patent extracts only the necessary authorization decision from the personal information without retaining the actual personal data. The charging station processes personal information to determine authorization status, then removes and deletes the personal information, keeping only the authorization result needed for charging control.
2Adaptability or versatility
If the charging station retains personal information for future reference, then service continuity and user identification are improved, but the compliance with data deletion rights and privacy protection deteriorate
Solution Approach 1:
The system creates a functional copy of the authorization decision rather than retaining the original personal information. The charging station uses personal information to generate an authorization token or decision that enables service continuity without storing the sensitive personal data itself, thus complying with deletion requirements while maintaining service functionality.
3Productivity
If the charging station processes personal information in real-time, then the charging approval speed is improved, but the computational resources and system complexity increase
Solution Approach 1:
The patent extracts only the essential authorization decision from complex personal information processing. The charging station focuses on analyzing specific authorization-relevant data elements rather than processing all personal information comprehensively, reducing computational complexity while maintaining real-time approval capability.

AI summary
An example operation includes one or more of determining, by a charging station, that a vehicle requests approval to receive a charge; accessing, by the charging station, personal information related to the vehicle and related to an occupant of the vehicle; analyzing, by the charging station, the personal information related to the vehicle and related to the occupant of the vehicle; determining, by the charging station, to grant the approval, based on the analyzing; and, responsive to the approval being granted, deleting, by the charging station, the accessed personal information related to the vehicle and related to the occupant of the vehicle, after the vehicle has received the charge.
