Medical Detectives – Forensische Aufklärung von Verbrechen


Forensische Videoanalyse in der Täterermittlung
Der Markt der Videoüberwachung ist uneinheitlich und nur schwer in Zahlen zu beziffern. Überwachungsvideo gewinnen immer mehr an Bedeutung in der Verfolgung und Aufklärung der Verbrechensbekämpfung. Sie dienen aber auch als Beweismittel bei Handlungsabläufen in der Polizeiarbeit. Photogrammetrie ermöglicht eine exakte dreidimensionale geometrische Rekonstruktion des aufgenommenen Objektes.

Speaking can be seen as a process that converts a statement of the speaking person into spoken language. The first part of the article “Speaker verification in crime research” focused on the characteristics of phonetics and phonology and the possibilities of speech analysis. Certain minimum requirements for the nature of the investigation material are necessary if speaker recognition becomes forensically significant and identification or verification can be accepted in court.

If suspects are to be convicted of their crimes, a language analysis is often considered. The parties to the proceedings often expect more from the results of the analysis than they can offer in a subsequent interpretation of probabilities. Evidential proof is not always possible. The speaker of the crime neither reveals themselves nor are they cooperative.

Abstract. In recent years, the number of attempts to use digital audio and video evidence in litigation in civil and criminal proceedings has increased. Technical progress makes editing and changing music, film and picture recordings much easier, faster and better. The methods of digital sampling differ from the conventional pirated copy in that using a sample involves extensive changes and editing of the original work. Different digital sampling methods make the technical analysis and the legal classification more difficult. Targeted analysis methods can clearly identify a case of sampling and belong to the main field of forensic analysis. If persuasive evidence of an unauthorized use of sampling cannot be produced, the proof is useless in the legal process. Labelling technologies that are applied correctly make an important contribution to the effective detection of unauthorised sound sampling. There are hardly any holistic approaches that integrate the problem of sound sampling into the fields of analysis, identification, and labelling. In combination with specific technical protective mechanisms against sampling, an unauthorised use of samples protected by copyrights can be prevented or reduced. Using and sampling somebody else’s piece of music or video can be a copyright infringement. The copyright and the neighbouring rights of performing artists and the neighbouring rights of phonogram producers are affected by the consequences of illegal sampling. Part 1 of the article introduces the problems of digital audio sampling, Part 2 describes the typical manifestations of sampling, Part 3 illustrates various analytical procedures for the detection of audio sampling and Part 4 shows the identification by labelling strategies.

IJCSDF Cover

The International Journal of Cyber-Security and Digital Forensics (IJCSDF) is a knowledge resource for practitioners, scientists, and researchers among others working in various fields of Cyber Security, Privacy, Trust, Digital Forensics, Hacking, and Cyber Warfare. We welcome original contributions as high quality technical papers (full and short) describing original unpublished results of theoretical, empirical, conceptual or experimental research. All submitted papers will be peer-reviewed by members of the editorial board and selected reviewers and those accepted will be published in the next volume of the journal.

As one of the most important aims of this journal is to increase the usage and impact of knowledge as well as increasing the visibility and ease of use of scientific materials, IJCSDF does NOT CHARGE authors for any publication fee for online publishing of their materials in the journal and does NOT CHARGE readers or their institutions for accessing to the published materials!

As such, IJCSDF reserves the right to select only best submitted papers for publication. All submitted papers would be reviewed by at least two reviewers and one member of editorial committee.
