On the occasion of publications and online reports of third parties that question the completeness and reliability of the laboratory investigation by the Hellenic Police Criminal Investigations Division (DEE) regarding videos related to the Tempe railway accident:

The Criminal Investigations Directorate is the material competent Greek Police Service to conduct forensic investigations and drafting laboratory expertsapplying modern, scientifically documented, internationally recognized and judicial admissible methods, which are certified in accordance with international ISO standards.

In this context and on the order of the competent appellant investigator, the DEE. drafted Two laboratory expert reports, in which all actions related to the traceability of the files, the analysis of system events are accurately reflects, as well as the technical inspection for any alterations or processing of the audiovisual material.

More specifically, All aspects of the route of the video files were analyzedboth on the log and the central servers / regional machines. Also, the actions of the users and the history of the files were imprinted on their complete traceability, and special software was developed with which it was achieved Deciption of event logs.

Indicative:

  1. All information referred to as ‘omissions’ or ‘unexplored questions’ have been highlighted and constituted part of the reports Laboratory expertise, which were identified, analyzed and clearly imprinted, so that Mr Investigator has a complete view of the history and traceability of files.
  2. Way functions (MD5 and SHA-1), which are considered unacceptable by technical consultants reports, are used by all forensic laboratories worldwide and They are part of a standard operating process of the DEE. (ISO17020). It is noted that by the DEE. In this case, as in all cases under investigation, both functions are used in combination, making it virtually impossible to identify two different files with the same combination of alphanumeric identities,
  3. Both recorded ‘IVMS’ software versions were recorded and analyzed as to how they operate, with the aim of detecting data on the traceability of video files,
  4. to alleged omission of metadata of video files From laboratory expert reports, after multiple laboratory tests, it has emerged that The controversial systems create private “Proprietary” coding video files and should not be treated as a ‘typical’ .mp4 configuration file,
  5. There is no chance of falsifying the timetables on both personal computers and serverssince all event logs have been exported, which form part of the examination and laboratory tests, while
  6. In terms of digital watercolors, a number of laboratory tests were carried out (such as a watercolor durability and its behavior, video merger, unstructured intervention, use of processing software, etc.) in copies of the video files in question, as well as a variety of video records and video records, of which it emerged as similar behavior to that of unprocessed videos.

The Directorate of Criminal Investigations has specialized staff, know -how and operational readiness for the analysis of even the most complex digital data, and stands with a timely consistency in its institutional role: supporting justice with technically unmistakable and legal admissions.
