Developing radio frequency based devices detection method in crime scene investigation

Today, many IoT devices, smart watches, smart wristbands, smart headphones have started to be used. Evidence collection in the field of digital forensics generally begins with the detection of visible evidence. The collection of electronic evidence, which is difficult to detect with the eye and is open to remote access, should have the priority at the crime scene. Changing and/or rendering inaccessible electronic evidence via remote access may prevent the crime from being clarified. In the thesis study, a method will be developed for the detection of mobile devices with active wifi or bluetooth connection and active broadcasting ports at the scene. The system was designed to be SDR-based programmable, frequency range and band can be changed, and development was made for scanning in different bands and finding the location of electronic evidence. The system consists of two main headings as detection and positioning.
