摘要

During the last years, criminals have become awareof how digital evidences that lead them to courts and jail arecollected and analyzed. Hence, they have started to develop antiforensictechniques to evade, hamper, or nullify their evidences. Nowadays, these techniques are broadly used by criminals, causing the forensic analysis to be in a state of decay. To defeatagainst these techniques, forensic analyst need to first identifythem, and then to mitigate somehow their effects. In this paper, wereview the anti-forensic techniques and propose a new taxonomythat relates them to the initial phase of a forensic process mainlyaffected by each technique. Furthermore, we introduce mitigationtechniques for these anti-forensic techniques, considering thechance to overcome the anti-forensic techniques and the difficultyto apply them.
