Mitigation of H.264 and H.265 Video Compression for Reliable PRNU Estimation
(Institute of Electrical and Electronics Engineers Inc., 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 ... -
On efficient computation of equilibrium under social coalition structures
(Turkiye Klinikleri, 2020)In game-theoretic settings the key notion of analysis is an equilibrium, which is a profile of agent strategies such that no viable coalition of agents can improve upon their coalitional welfare by jointly changing their ... -
A study on public perception and preferences about IoT security
(Institute of Electrical and Electronics Engineers Inc., 2019-09)Configuring internet of things (IoT) devices with easy or default passwords leads to serious vulnerabilities. In recent years, malware (Mirai etc.) which are capable of creating IoT botnets and organizing distributed denial ... -
HSV Color Histogram Based Image Retrieval with Background Elimination
(Institute of Electrical and Electronics Engineers Inc., 2019-11)In this study, a new content based image retrieval (CBIR) method, which uses HSV histogram data is proposed. The model uses the HSV histogram to find the background from the image by analyzing the peaks in the histogram data ... -
JpgScraper : An Advanced Carver for JPEG Files
(Institute of Electrical and Electronics Engineers Inc., 2020)Orphaned file fragment carving is concerned with recovering contents of encoded data in the absence of any coding metadata. Constructing an orphaned file carver requires addressing three challenges: a specialized decoder ... -
