EXTRACTING PRNU NOISE FROM H.264 CODED VIDEOS
Altinisik, Enes; Tasdemir, Kasim; Sencar, Husrev Taha (IEEE COMPUTER SOC, 10662 LOS VAQUEROS CIRCLE, PO BOX 3014, LOS ALAMITOS, CA 90720-1264 USA, 2018)Every device equipped with a digital camera has a unique identity. This phenomenon is essentially due to a systematic noise component of an imaging sensor, known as photo-response non-uniformity (PRNU) noise. An imaging ... -
Mitigation of H.264 and H.265 Video Compression for Reliable PRNU Estimation
Altinisik, Enes; Tasdemir, Kasim; Sencar, Husrev Taha (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 445 HOES LANE, PISCATAWAY, NJ 08855-4141 USA, 2020)The photo-response non-uniformity (PRNU) is a distinctive image sensor characteristic, and an imaging device inadvertently introduces its sensor's PRNU into all media it captures. Therefore, the PRNU can be regarded as a ... -
PRNU Estimation from Encoded Videos Using Block-Based Weighting
Altinisik, Enes; Tasdemir, Kasim; Sencar, Hüsrev Taha (Society for Imaging Science and Technology, 2021)Estimating the photo-response non-uniformity (PRNU) of an imaging sensor from videos is a challenging task due to complications created by several processing steps in the camera imaging pipeline. Among these steps, video ...
