DIGITAL FORENSIC ANALYSIS OF DATING APPLICATIONS IN THAILAND ON ANDROID USING THE INVESTIGATION MODEL OF DIGITAL FORENSIC RESEARCH WORKSHOP 2001

Abstract

This research aims to analyze digital forensic evidence obtained from the dating applications ThaiFriendly and ThaiCupid openrating on the Android platform using the investigation model of DFRW2001. The model consists of six phases: identification, preservation, collection, examination, analysis, and presentation. The digital forensic tools utilized were MOBILedit and Oxygen. The study simulated four scenarios data, including non-deleted data, messages deleted, data deleted with uncleared cache, and data deleted with cleared cache. This approach aimed to evaluate the effective of the tools. The findings revealed that MOBILedit demonstrated higher accuracy than Oxygen, achieving an average accuracy of 100% when data was not deleted and 83.33% when data was deleted but the cache remained uncleared. In comparison, Oxygen also achieved 100% accuracy when data was not deleted but dropped to 66.66% and 50% in scenarios where data was deleted with an uncleared cache. However, when data and cache were fully cleared, the accuracy of both tools dropped to 0%, highlighting their limitations in complex scenarios. This study highlights the imperative need for the development of more robust tools and the enhancement of data recovery techniques to enhance the comprehensiveness and accuracy of digital forensic investigations in the future.
