Given the limitations identified in the study, several alternative methods or approaches could be explored to enhance the forensic soundness of data acquisition from smartphones:
Physical Acquisition: Conducting a physical acquisition of the device's storage using specialized tools and techniques can provide a bit-by-bit copy of the device's data, ensuring a comprehensive and forensically sound acquisition.
Live Data Acquisition: Performing live data acquisition on the device while it is operational can capture volatile data, active processes, and real-time information that may not be available through traditional backup methods.
Memory Forensics: Utilizing memory forensics techniques to extract data from the device's RAM can uncover valuable information such as running processes, encryption keys, and user activities that may not be accessible through standard backups.
Cloud Forensics: Extending the investigation to include analysis of cloud storage, synchronization services, and online accounts linked to the device can provide a more complete picture of the user's digital footprint and activities.
Blockchain Analysis: Exploring blockchain technology and cryptocurrency transactions on the device can uncover additional evidence related to financial transactions, digital assets, and decentralized applications.
By incorporating these alternative methods and approaches into the forensic data acquisition process, investigators can enhance the depth, accuracy, and reliability of the evidence obtained from smartphones.
