Method and system for tracing fund link based on directional anchor point and balance consistency constraint
By employing a fund flow tracing method with directional anchor points and balance consistency constraints, and utilizing inverted indexes and net change ledgers for reverse tracing, this method solves the problems of query efficiency, path accuracy, and result interpretability in existing fund tracing methods for efficient and accurate directional relationship mining scenarios. It achieves efficient and reliable fund flow tracing and structured evidence generation.

Abstract
The application discloses a fund link backtracking method and system based on directional anchor point and balance consistency constraint, and belongs to the technical field of big data analysis. The method comprises the following steps: locating anchor point transaction according to a suspect list; constructing an entry reverse index of transaction data and a net change ledger of each account; and reversely tracking the anchor point transaction in combination with the entry reverse index to obtain all feasible fund link sets with the anchor point transaction as a starting point; wherein the authenticity of each layer of fund connection is ensured based on the net change ledger in the reverse tracking process. The application can analyze massive water data, thereby efficiently and credibly tracing the source of the case-related fund, and generating a structured evidence chain meeting the requirements of judicial evidence.
