Time is on my side: Steganography in filesystem metadata

Sebastian Neuner, Artemios G. Voyiatzis, Martin Schmiedecker, Stefan Brunthaler, Stefan Katzenbeisser, Edgar R. Weippl
2016 Digital Investigation. The International Journal of Digital Forensics and Incident Response  
We report a proof-of-concept implementation and confirm that the embedded information is indistinguishable from that of a normal filesystem use.  ...  We identify an information gap between storage and usage of timestamps in modern operating systems that use high-precision timers.  ...  We aim for a steganographic storage system based on file timestamps, namely TOMS (Time-On-My-Side) that is stealthy, robust, and applicable in a wide range of scenarios.  ...

Digital evidence review 2016–2019

Paul Reedy
2020 Forensic Science International: Synergy  
This review paper covers the forensic-relevant literature in digital evidence from 2016 to 2019 as a part of the 19th Interpol International Forensic Science Managers Symposium.  ...  On examination of the Spotlight metadata, it was found that there was complete metadata present that referenced the files in question.  ...  [92] propose a new digital forensic approach that combines cloud-side and client-side forensics. The device operations are based on Alexa, therefore the artifacts are located in the cloud.  ...

Data-Centric Examination Approach (DCEA) for a qualitative determination of error, loss and uncertainty in digital and digitised forensics [article]

Stefan Kiltz, Universitäts- Und Landesbibliothek Sachsen-Anhalt, Martin-Luther Universität, Jana Dittmann
We firstly formally describes loss, error and uncertainty regarding data contained in IT systems based on a mode [...]  ...  Based on those facts, in this thesis we set ourselves the research question of whether a data-centric approach can be designed to preserve data/tool sovereignty of the forensic examiner and to prevent  ...  On the output side we not only look at errors but also loss and uncertainty.  ...
