Both the legal norms and case law leave open how IT traces that can be linked to a perpetrator are to be evaluated. Even with regard to technical standards, there is no approach to systematically evaluate IT traces so that a connection with the perpetrator, the crime scene and the time of the crime can be established or excluded. In order to determine the guilt or innocence of the defendant, it must be established with almost certainty that there is no reason for acquittal, taking into account the free assessment of evidence. In general, assessing IT traces as to guilt or innocence is a vague matter that can only be accomplished with a lot of responsibility and expertise in order to minimize any bias. There is a complete lack of supporting tools, methods or procedures. This work attempts to extend a 7-stage scale for evaluating traces described in the literature in a multidimensional manner, so that a systematic approach to evaluating traces in IT is created.
