Gathering forensic data from mobile devices has become essential with the rise of mobile technology and the value of the data they store. This thesis looked at a new analysis platform, which we called "T," and compared its output with an existing tool, Cellebrite’s Physical Analyzer (CPA). We imaged 22 different devices with Cellebrite’s imaging software and then analyzed the images with both tools. The phones were categorized into 1 of 7 categories based on their content and usage. We concluded that CPA and T have different benefits. CPA was strongest in its user interface and ability to determine web usage, as well as being able to analyze a variety of devices. T had the ability to allow for keyword searches, which allowed us to be able to identify more email address possibilities. We propose testing more recent updates of the tools against a larger corpus of phones in future work.
