Sensor Fingerprint Tool

PRNU Noise Analyzer

Verify image authenticity through sensor fingerprint analysis. Every real camera leaves a unique Photo Response Non-Uniformity (PRNU) noise pattern — AI images lack this fingerprint.

How PRNU Analysis Works

Camera sensor imperfections create a unique noise fingerprint that AI cannot replicate

Sensor Fingerprint

Every physical camera sensor has manufacturing imperfections that create unique noise patterns in every photo it captures.

Noise Extraction

Our tool extracts the noise residual from the image and analyzes its spectral properties to determine if it matches real camera noise.

AI Detection

AI-generated images produce synthetic noise that lacks the characteristic patterns of real camera sensors, making detection possible.
