With the increasing usage of social networks and the emergence of cloud computing, digital forensics face a number of research problems and challenges. The number of users of these services increases steadily, with Facebook (the largest current social network) claiming to have 800 million users. While traditional forensics relies on the physical acquisition of hardware and the usage of hashsums to ensure evidence reliability, this approach does not scale to cloud services and their use of distributed datacenters. With the lack of standardized forensics APIs as well as unified processes for service operators, isolated solutions are still in widespread use. Another important aspect of forensics is the proper visualization of data due to the vast amount of available data.

It is furthermore hard to visualize gathered social networking data in a way that can answer common questions of interest on a first sight, so that people without technical background can understand it. This has been shown for example in the case of the consolidated.db from Apple’s iPhone: the file contained geo-location information which has been already outlined in 2010. However, the consolidated.db problem got widespread attention with the release of the iPhoneTracker software [6] in April 2011, which visualized the collected data.
