prnu

Python implementation of PRNU extractor

Implementation of the famous Camera Noise Fingerprint "NoisePrint" in Pytorch

A Python script that extracts the PRNU from images using the DRUNet network as a denoising technique.

This repository provides a PyTorch implementation of FFDNet image denoising https://arxiv.org/abs/1710.04026. First implemented by Matias Tassano https://doi.org/10.5201/ipol.2019.231, the FFDNet source code has been adapted so as to extract cameras PRNU.

Zero-knowledge circuits for sensor-based photo provenance (Noir / UltraHonk)

The Video Truth Record (.vtr) is an open standard for hardware-attested media. It cryptographically binds video files to the unique physical signature of the camera sensor (PRNU) at capture, utilizing zero-knowledge proofs to guarantee authenticity and an unbroken chain of custody.

Deep Learning framework for Source Camera Identification using PRNU (Sensor Pattern Noise), Wavelet Residual Extraction, CNN Feature Learning, and Hybrid Feature Fusion.

Wavelet-domain PRNU based image authentication system for verifying whether an image originates from an enrolled camera sensor.

Python program for analyzing the device using which the picture was taken.
