TL;DR: Wang et al. as discussed by the authors presented how the database and main files of instant messaging (IM) apps are stored and encrypted, as well as how the apps verify passwords, and they also presented a decryption methodology for the databases and multimedia files of two IM apps, i.e., Wickr and Private Text Messaging.
Abstract: Currently, obtaining digital evidence from instant messaging (IM) apps is being considered. IM apps store personal user data, e.g., user information, chat messages, and multimedia files, most IM apps protect the stored data using secure cryptographic algorithms such that only an authorized person can access the app data. Accordingly, it is important to develop a decryption method for IM app data for digital forensic investigations. In this paper, we present how the database and main files of IM apps are stored and encrypted, as well as how the apps verify passwords. We also present a decryption methodology for the databases and multimedia files of two IM apps, i.e., Wickr and Private Text Messaging, which provide various secure communications, e.g., text messages and multimedia files. The decrypted data of these IM apps was verified in simulations.

TL;DR: The aim of this work is to discover methods of extracting and analysing data from an Android based smartphone using the Sleuth Kit Autopsy to obtain email, contact, messages, calendar, and images data that can be used as digital evidence in an investigation.
Abstract: The advancement of wireless technology and mobile devices have change our life tremendously. The number of smartphone users increases and majority people rely on it for communication and business related matters. While smartphones are used for positive aspects of our life, it is also used by criminals as medium for their modus operandi. Therefore, there are potential information stored in smartphones that can be used for digital evidence as part of an investigation. However, investigators may face challenges in extracting crucial information and the vital data stored in the smartphone. In this paper, we share on how we studied and experimented several methods on how data in smartphones can be extracted and analysed using the Sleuth Kit Autopsy. The aim of this work is to discover methods of extracting and analysing data from an Android based smartphone. We managed to obtain email, contact, messages, calendar, and images data that can be of used as digital evidence in an investigation.
