Enhancement Of Media Splicing Detection: A General Framework, Songpon Teerakanok, Tetsutaro Uehara
Enhancement Of Media Splicing Detection: A General Framework, Songpon Teerakanok, Tetsutaro Uehara
Journal of Digital Forensics, Security and Law
Digital media (i.e., image, audio) has played an influential role in today information system. The increasing of popularity in digital media has brought forth many technological advancements. The advancements, however, also gives birth to a number of forgeries and attacks against this type of information. With the availability of easy-to-use media manipulating tools available online, the authenticity of today digital media cannot be guaranteed. In this paper, a new general framework for enhancing today media splicing detection has been proposed. By combining results from two traditional approaches, the enhanced detection results show improvement in term of clarity in which anomalies …

Fingerprinting Jpegs With Optimised Huffman Tables, Sean Mckeown, Gordon Russell, Petra Leimich
Journal of Digital Forensics, Security and Law
A common task in digital forensics investigations is to identify known contraband images. This is typically achieved by calculating a cryptographic digest, using hashing algorithms such as SHA256, for each image on a given medium, and comparing individual digests with a database of known contraband. However, the large capacities of modern storage media and time pressures placed on forensics examiners necessitates the development of more efficient processing methods. This work describes a technique for fingerprinting JPEGs with optimised Huffman tables which requires only the image header to be present on the media. Such fingerprints are shown to be robust across …
Drone Forensic Analysis Using Open Source Tools, M A Hannan Bin Azhar, Thomas Edward Allen Barton, Tasmina Islam
Drone Forensic Analysis Using Open Source Tools, M A Hannan Bin Azhar, Thomas Edward Allen Barton, Tasmina Islam
Journal of Digital Forensics, Security and Law
Carrying capabilities of drones and their easy accessibility to public have led to an increase in crimes committed using drones in recent years. For this reason, the need for forensic analysis of drones captured from the crime scenes and the devices used for these drones is also paramount. This paper presents the extraction and identification of important artefacts from the recorded flight data as well as the associated mobile devices using open source tools and some basic scripts developed to aid the analysis of two popular drone systems- the DJI Phantom 3 Professional and Parrot AR. Drone 2.0. Although different …
