Power Line Filtering to Block Rack-Level Data Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing datacenter and equipment rack security measures fail to effectively prevent data capture from power lines, particularly through proximity sensors, which can extract data without direct contact.
Innovation Solution
Installation of a power line filter device upstream of power distribution units (PDUs) and distribution switchboards to condition signals and prevent unwanted data emission, functioning as a firewall to shield IT equipment from data capture by reforming voltage and current waveshapes and blocking inductive coupling.

Engineering Contradiction Analysis
1Use of energy by moving object
If power lines are used to supply power to IT equipment, then power distribution is achieved, but data can be captured from the power lines through proximity sensors
Solution Approach 1:
A power line filter device is introduced as an intermediary component between the power source and the IT equipment. This filter acts as a mediator that allows power to pass through while blocking the transmission of data-carrying electrical signals on the power lines, thus preventing proximity sensor data capture while maintaining normal power distribution functionality
Solution Approach 2:
The harmful data-carrying signal component is extracted and removed from the power lines using the filter device. The filter separates the useful power transmission function from the harmful data emission function, eliminating the security vulnerability while preserving the essential power supply capability
2Reliability
If security measures are added to prevent data capture from power lines, then data security is improved, but device complexity increases
Solution Approach 1:
The power line filter serves as a dedicated intermediary security component that handles the data protection function independently. By placing the filter at a strategic point in the power distribution path, it provides comprehensive security protection without requiring modification of the IT equipment themselves, thus limiting the increase in overall system complexity to a single discrete device
Solution Approach 2:
The security function is segmented into a separate, standalone power line filter device rather than being integrated into the IT equipment or power distribution system. This modular approach allows the security measure to be added independently and simplifies maintenance and replacement without affecting other system components
