Novel Anti-forensics Approaches for Smart Phones

Anti-forensics is defined as a method undertaken to thwart the digital investigation process conducted by forensic investigators. In this paper we introduce the design and implementation of three novel anti-forensic approaches for data deletion and manipulation on three of the market-leading forensics tools. The evaluation results of our proposed anti-forensic approaches on a typical Android cell phone device demonstrate the severe limitations of current forensic tools and conclude the critical need for modifications and/or redesigns of these contemporary forensic tools to maintain accuracy and legitimacy of forensic data acquisition and analysis.
