Steps in Forensic Image and Audio Analysis's Preparation
Forensic video analysis is a complex and broad field that often involves several skipped and overlooked steps. Like computer forensics, which involves more than just copying and examining files, forensic video analysis requires a comprehensive approach. Considering all the tasks involved in this analysis can be pretty intimidating.
Forensic video analysts must know all the necessary procedures to conduct a thorough analysis, as it helps maintain organization and reduces the likelihood of skipping or forgetting critical stages. Moreover, having a detailed outline serves as the framework for the analyst’s presentation if they need to appear in court.
It is essential to keep in mind that watching and editing videos are not the only duties of a digital video analyst. The process begins with finding the data, correctly decoding it, documenting the procedure, comparing it with other data, and finally appearing in court.
Preparatory Steps for Conducting Forensic Image and Video Analysis
To conduct a thorough forensic image and video analysis, there are several preparatory steps that analysts typically take:
Phase 1 – Retrieve the Data: The integrity of the evidence depends on the success of this phase, which needs to be addressed. Analysts need to retrieve the actual evidence and exercise caution when handling it.
Phase 2 – Decode the Data: Extracting something to examine from the bits is the next step. This can prove challenging, given the numerous proprietary video file formats available.
Phase 3 – Locate the Data’s Origin: Understanding the source and the file format is essential. Knowing the nature of the source, the type of camera used, and the same camera used to take the photo can provide valuable information.
Phase 4 – Check Data Integrity: Analysts must determine if the information gathered is reliable and if it was tampered with or altered.
Phase 5 – Determine Data Quality: Analysts must decide if the gathered data is of sufficient quality and if any forensic video enhancement or restoration procedures could help retrieve or display the data more clearly.
By following these preparatory steps, forensic analysts can ensure that their image and video analysis is thorough, accurate, reliable, and admissible in court.
