摘要：The existence of anti-forensic tools in the context of computing systems is one of the main challenges for forensics investigators in achieving reliable evidence recovery and consequently uncovering crime facts. This is in particular more challenging in emerging smartphone technologies, since data is of highly mobile and volatile nature. In the current paper, we present a brief study of several anti-forensic applications available for smartphones. The applications are ready to use, most of them free, and require no expert technical knowledge. Moreover, these have been proved to be very effective when tested with two commercial forensic tools.
