Recent Advances in Counter PRNU Based Source Attribution and Beyond
(SPIE-INT SOC Optical Engineering, 2015)
Photo response noise uniformity (PRNU) based source attribution has proven to be a powerful technique in multimedia forensics. The increasing prominence of this technique, combined with its introduction as evidence in the ...
Sensor Fingerprint Identification Through Composite Fingerprints and Group Testing
(IEEE-INST Electrical Electronics Engineers Inc., 2015-03)
The photo response non-uniformity noise associated with an imaging sensor has been shown to be a unique and persistent identifier that can be treated as the sensor's digital fingerprint. The method for attributing an image ...
Carving Orphaned JPEG File Fragments
File carving techniques allow for recovery of files from storage devices in the absence of any file system metadata. When data are encoded and compressed, the current paradigm of carving requires the knowledge of the ...
