| Summary: | —Instant messaging applications, including WhatsApp, Viber, and WeChat, are moving beyond text messages to videos and voice calls, which are proportioned to current media, files, and locations. In this study, we surveyed existing forensic visualization and forensic analysis techniques for instant messaging applications, with the aim of contributing to the knowledge in the discussion of these research issues. A
total of 61 publications were reviewed after searching various
academic databases, including the IEEE, ACM Digital Library,
Google Scholar, and Science Direct during the last five years.
Our observation from research trends indicates that both
forensic analysis and information visualization are relatively
mature research areas. However, there is a growing interest in
forensic visualization and automated IM forensic analysis. We
also identified the lack of discussion on forensic selection criteria in existing forensic visualization works and the needs of benchmarking the evaluation method of automate forensic
analysis tools.
