Towards automated digital alibis
Studium: Masterstudium Software Engineering & Internet Computing
BetreuerIn: Privatdoz. Dr. Edgar Weippl
In recent years, society is using media and communication technology more.
One consequence of this is that there is more opportunity for its abuse, as well
as use in crime. If there is more criminal usage of digital communication
technology, we need to reliably be able to use digital evidence in both prosecutions
and criminal defence cases. The main focus of this study is to show that
forging of digital alibis is possible, which can impact on the reliance on digital
evidence. The creation of a digital alibi using automation is the focus of other
studies, and we are also looking at: social interaction during the simulation of a
users behaviour, and whether behaviour can be simulated realistically and with
limited computer evidence of the simulation. For this purpose an alibi framework
is created that mimicked a typical users behaviour. This automation is
intended to be implemented in such a way that it may not be possible to
decide whether the traces of exercising actions recorded on the computer
originate from either: a human user or a simulated user. Furthermore, forensic
analysis is applied to verify whether the framework leaves any traces behind
that could indicate the usage of a simulator. Social interaction is simulated by
using a chatbot which used email and messaging and analysed the computers
for their performance in creating a digital alibi. The performance criteria for the
framework was based on metrics taken from real person computer behaviour.
By evaluating the forensic analysis of simulated users hard drive and the real
persons behaviour, it turned out that the simulator fits in the average range of
real persons for nearly all categories. Therefore, simulation of users behaviour
is possible, on condition that determining the sources of digital evidence is
hard to verify. However, having a closer look at social communication, there is
room for improvement, e.g. the chatbots text comprehension and email
content.
