Sotiris, tell us what you are doing at the Cyprus Police.
I am the Head of Photographic and Graphic Lab, of the Cyprus Police Criminalistic Services. I have a Master’s Degree in Communication. Our lab activities include Crime Scene Photography, Forensic Photography, Image and Video Analysis and Enhancement, CCTV Retrieval and Analysis, Facial or Items Comparison, Image Authentication, and etc.
Why did you choose to work in the field of multimedia forensics?
I have always been interested in image and video processing, especially creating funny TV productions where everything can be done. When I joined the police force and started to work in the Photographic and Graphic Lab (it was around the year 2000) I had received the first case about video authentication. This is what made me start thinking about the field of multimedia from another perspective. The new challenge for me was not to know how to create or manipulate a video but to know how to look for traces to identify if a video was authentic or not. Even though it was for analog video, I found the entire procedure, analysis and investigation very interesting.
You’ve been in this role for quite a long time. What do you think are the biggest challenges with multimedia digital evidence and investigating crimes?
I think the biggest challenge is when you have to deal with massive video data coming from different DVRs. We are also faced with problems when we collect or retrieve the footage from these systems. For sure, this is not an easy procedure. Moreover, the video compression (artifacts, loss of details), low frame rates, and in general, the low quality of footage we get from these systems is a challenge.
