Research on Electronic Data Forensics Issues and Rule Reconstruction in Fourth-Party Payment-Based Cyber Money Laundering Crimes

This study investigates the critical challenges and corresponding solutions in electronic data forensics within the context of fourth-party payment-based cyber money laundering crimes. As digital finance evolves, the abuse of fourth-party payment platforms for money laundering has become increasingly rampant, making electronic data the cornerstone of conviction and sentencing. However, current practices are hindered by outdated legal frameworks, ambiguous procedural norms, and inadequate mechanisms for ensuring the defendant's right to cross-examination.To address these systemic gaps, this paper first identifies the key application dilemmas of electronic data evidence in such cases. Subsequently, it proposes targeted strategies for rule reconstruction, including the formulation of specialized legal guidelines, standardization of forensic procedures, and strengthening of the defendant's right to cross-examination through technical assistance and improved evidence disclosure.The theoretical significance of this research lies in filling the gap in evidence law scholarship regarding emerging cybercrimes. Practically, it aims to provide law enforcement and judicial authorities with a more robust, fair, and efficient framework to combat fourth-party payment-based money laundering and safeguard financial stability.
