Illicit data resale detection method via an enhanced relational graph convolutional network
Illicit data resale in data trading scenarios exhibited strong concealment and was difficult to detect. An enhanced relational graph convolutional network was proposed by optimizing message passing and feature aggregation with transaction contextual similarity and causal temporal order constraints
enabling effective representation of illicit resale behaviors under complex transaction relations. Based on this model
a detection method was developed to predict the existence of illicit resale behaviors in transaction topology graphs. A simulated data trading dataset containing anomalous resale samples was constructed
and comparative experiments were performed. The results indicate that the proposed method provides an effective solution for illicit data resale detection in data trading scenarios.
