Considerations on the benchmarking of media forensics

In media forensics, most of the approaches are still far away from being mature enough for admission in court - the ultimate benchmark for any forensic method. The intended contribution of this paper is to facilitate the understanding between the researchers active in this field and the society perspective on media forensics. The intended benefit of this is that it allows these two to better understand each other: On one hand, showing researchers working on the development of forensic methods a precise picture of the compliance requirements installed by the society (here, requirements for potential court admissibil-ity); on the other hand, intending to help non-technicians to understand the challenges that researchers face. To achieve this contribution, a selected prominent example (the photo response non-uniformity (PRNU) based digital camera forensics) is discussed here briefly in the context of the established Daubert criteria as reference imposed as admissibility threshold for legal proceedings.
