Power-side processor integrity monitor for critical systems
Power Fingerprinting (PFP) is a security monitoring technique that watches a computer processor's electricity consumption patterns in real time to verify that it is running exactly the software it's supposed to run. Just as a person's heartbeat has a unique signature, every software routine draws power in a distinctive pattern; any deviation—caused by malware, tampering, or unauthorized code—shows up as an anomaly. The system pre-characterizes trusted software execution profiles, stores them as reference fingerprints, and continuously compares live power readings against those baselines, triggering an alert when the gap exceeds a statistical threshold. This approach catches attacks that evade traditional software-based security tools because it monitors physical hardware behavior rather than relying on the compromised system to report on itself.
What you could build
A hardware-plus-software security monitoring appliance for industrial control systems, military embedded computers, and critical-infrastructure devices that continuously validates processor execution integrity through power-side analysis—sold to defense contractors, utilities, and industrial OEMs as a compliance and threat-detection layer.
Who in Virginia should care
Northern Virginia and Hampton Roads defense primes, government systems integrators, and DHS/DoD program offices managing embedded-system security requirements would be natural licensees or partners.
Readiness: Prototype likely
Concept — described but not yet demonstrated. Lab validated — supported by experimental results in the patent. Prototype likely — the text describes a built, working embodiment.
Readiness is inferred from the patent text, not from a lab visit.
