Forensics Analysis of Lock Application on Mobile Devices

Abstract

Encryption is a technique used to support confidentiality from the information. At this
time, many applications that provide encryption services for information security on
mobile phones like lock gallery, data, etc. These applications are also currently widely
used by mobile users. This application will undoubtedly be challenging for digital
examiner forensics when the cell phone is evidence using the lock application. To
encounter these challenges, this is necessary to prove scientific that can recover
encrypted data so that it can assist in the analysis process. In this study, the researcher
will use a forensic tool, namely XRY and manual acquisition, using ADB. The results
obtained to know to go beyond which forensic tools can be relied on, make a Lock
Applications profile, which is possible to get the key that the application uses.
