Abstract [en]

In the field of IT-forensics you may often get to analyze different types of digital devices. One ofthese devices is the GPS navigation system. Nowadays GPS technology is getting more and morepopular and is included more frequently in different types of devices. With this article we want topresent the differenent obstacles and possibilites that a forensic investigator is presented with in thistype of investigation. We will be comparing different software suites and make use of forensic toolssuch as EnCase.The reader should get some understanding of the methods there are for analyzing one of these devicesand what problems that may occur in the investigation process.The article presents how the investigator can use different methods to gain information such as recentroutes, favourite destinations and other information that may be stored on the device. The amountof information stored on the device depends purely on the device modell that is being analyzed.We will present the process of how to aquire and analyse data from four different GPS devices, twomodels from Garmin and two models from TomTom. The data we have aquired is saved favourites,traveled routes and history from phone calls. We have also done a comparison between two softwaresuites, EnCase and Blackthorn2. Our results have varied between the softwares, with both positiveand negative results. The devices from Garmin gave us the best results in this study.
