Abstract

In the modern digital society, mobile phone screenshots are essential for documenting data, proving events, and providing legal evidence. However, modern digital technologies have made taking screenshots easy. Significant differences exist between screenshots and traditional mobile photography images in the formation way, leading to immature industry research in screenshot source tracing, by complicating the authenticity proof. The study aims to explore critical methods and techniques in the source tracing and authentication of mobile phone screenshots. The paper involves collecting screenshot images produced by 50 common mobile phone models available in the market and analyzing their metadata. This research employs a multifaceted analysis of screenshots, using metadata, image characteristics, file naming patterns, and unique markers to trace their origins to specific mobile and working versions. Based on this, the paper further discusses the main challenges faced in mobile screenshot source tracing and authentication. Results show that, despite challenges, integrating digital forensics and multidimensional feature detection enables reliable tracing and authentication of mobile screenshots. The research provides essential technical support and data backing for the authenticity proof of images in forensic science or legal examination and the source tracing of mobile.
