Digital traces play an important role in the crime detection and the process of proof. In contrast to traditional types of forensic traces, in the case of digital traces, the perpetrator is not always aware of the fact of leaving them, and attempts to remove or deliberately modify such traces in the absence of adequate knowledge and relevant skills often end in relative failure.
