Camera Fingerprint Extraction via Spatial Domain Averaged Frames
Samet Taspinar, Manoranjan Mohanty, Nasir Memon
Photo Response Non-Uniformity (PRNU) based camera attribution is an effective method to determine the source camera of visual media (an image or a video). To apply this method, ima…
FiFTy: Large-scale File Fragment Type Identification using Neural Networks
Govind Mittal, Pawel Korus, Nasir Memon
We present FiFTy, a modern file type identification tool for memory forensics and data carving. In contrast to previous approaches based on hand-crafted features, we design a compa…
Source Camera Attribution of Multi-Format Devices
Samet Taspinar, Manoranjan Mohanty, Nasir Memon
Photo Response Non-Uniformity (PRNU) based source camera attribution is an effective method to determine the origin camera of visual media (an image or a video). However, given tha…
Analysis of Rolling Shutter Effect on ENF based Video Forensics
Saffet Vatansever, Ahmet Emir Dirik, Nasir Memon
ENF is a time-varying signal of the frequency of mains electricity in a power grid. It continuously fluctuates around a nominal value (50/60 Hz) due to changes in supply and demand…
Detecting the Presence of ENF Signal in Digital Videos: a Superpixel based Approach
Saffet Vatansever, Ahmet Emir Dirik, Nasir Memon
ENF (Electrical Network Frequency) instantaneously fluctuates around its nominal value (50/60 Hz) due to a continuous disparity between generated power and consumed power. Conseque…
Neural Imaging Pipelines - the Scourge or Hope of Forensics?
Pawel Korus, Nasir Memon
Forensic analysis of digital photographs relies on intrinsic statistical traces introduced at the time of their acquisition or subsequent editing. Such traces are often removed by…
