Cloud-based mobile application forensics focuses on investigating digital evidence that originates from mobile apps leveraging cloud services for data storage, synchronization, and processing. Research in this field emphasizes the development of methodologies and frameworks to collect, preserve, and analyze data distributed between mobile devices and cloud infrastructures. Key topics include forensic acquisition of app-related cloud data, recovery of deleted or synced information, and analysis of API communication between mobile apps and cloud servers. Other significant research areas involve privacy-preserving forensic procedures, cross-platform evidence correlation, and the use of blockchain for secure evidence integrity verification. Emerging directions also explore the integration of artificial intelligence for automated artifact classification, forensic readiness for cloud-hosted applications, and standardized frameworks to ensure legal admissibility of cloud-based mobile evidence. Additionally, developing techniques to handle encrypted or volatile app data and creating unified forensic models that bridge mobile and cloud ecosystems remain vital challenges in this growing research domain.
