Data integrity–assured mobile forensics focuses on ensuring that digital evidence collected from mobile devices remains unaltered, authentic, and legally admissible throughout the forensic process. Research in this area emphasizes designing secure and verifiable methodologies for evidence acquisition, preservation, and analysis. Key topics include cryptographic techniques for tamper-proof evidence, blockchain-based mechanisms for traceable chain of custody, and integrity verification of volatile and non-volatile data from mobile devices. Other research directions involve secure logging and monitoring for mobile applications, AI-assisted anomaly detection to identify potential evidence tampering, and privacy-preserving frameworks for handling sensitive user data. Emerging areas also explore real-time integrity validation during mobile forensic acquisition, forensic readiness models for mobile ecosystems, and standardized procedures to ensure compliance with legal and regulatory requirements. Addressing challenges related to multi-platform devices, encrypted data, and cloud-synchronized mobile content is central to advancing research in data integrity–assured mobile forensics.
