IED Image Capture for Unauthorized Access Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Intelligent electronic devices (IEDs) lack effective mechanisms to prevent unauthorized access, which can lead to incorrect or corrupted data and potential damage, necessitating enhanced security features for user-selectable operational features.
Innovation Solution
Incorporating a user authentication module with biometric or ID card readers, coupled with an image capture module that transmits images upon tamper detection or authentication failure, to ensure only authorized users access sensitive features of IEDs like digital power and energy meters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional access control methods are used in IEDs, then device complexity is reduced, but security against unauthorized access is insufficient
Solution Approach 1:
The patent segments the IED into multiple functional modules including a separate authentication module that handles biometric verification, an image capture module for evidence collection, and the main metering module. This segmentation allows security functions to be isolated and managed independently, improving security without overwhelming the entire device complexity.
Solution Approach 2:
The patent introduces an intermediary authentication module that acts as a mediator between users and the IED's operational features. This module uses biometric sensors and image capture capabilities to verify user identity before granting access, providing enhanced security while maintaining manageable device complexity through modular design.
2Reliability
If biometric sensors and image capture modules are added to IEDs, then unauthorized access prevention is improved, but device complexity increases
Solution Approach 1:
The patent merges the biometric authentication functionality and image capture capability into a unified security system within the IED. By combining these functions under a single authentication module, the patent reduces the overall device complexity compared to having separate independent systems, while still providing robust unauthorized access prevention.
Solution Approach 2:
The authentication module is designed with multi-functionality, serving both as a biometric verification system and an evidence collection system through integrated image capture. This universal design allows a single module to perform multiple security-related functions, reducing device complexity while improving unauthorized access prevention.
3Reliability
If authentication procedures are implemented, then data accuracy is protected, but ease of operation decreases
Solution Approach 1:
The patent replaces traditional mechanical or manual authentication methods (such as passwords or physical keys) with biometric authentication using fingerprint or iris sensors. This substitution maintains data accuracy protection while improving ease of operation, as biometric authentication is more convenient and user-friendly compared to traditional methods.

AI summary
An intelligent electronic device (IED) includes an image capture module configured for capturing images or video in a location of the IED. The IED may also include a heat sensor for sensing heat inside or outside a housing of the IED. In one application, these techniques are implemented in IEDs such as electrical power and energy meters and used to control access to reset, configuration, billing, communication, and data acquisition/processing functions of the meters. Additionally, image processing techniques are employed by the IED to detect events in an electrical distribution system and implement control functions thereof.
