IOS anti-forensics: How can we securely conceal, delete and insert data?

Abstract

With increasing popularity of smart mobile devices such as iOS devices, security and privacy concerns have emerged as a salient area of inquiry. A relatively under-studied area is anti-mobile forensics to prevent or inhibit forensic investigations. In this paper, we propose a "Concealment" technique to enhance the security of non-protected (Class D) data that is at rest on iOS devices, as well as a "Deletion" technique to reinforce data deletion from iOS devices. We also demonstrate how our " Insertion" technique can be used to insert data into iOS devices surreptitiously that would be hard to pick up in a forensic investigation. © 2014 IEEE.
