Document Type and Number:

WIPO Patent Application WO/2019/114434

Kind Code:

A1

Abstract:

A graphical structure model-based method for transaction risk control, and device and equipment, comprising: building in advance a suitable transaction data network on the basis of data relating to user transactions; performing feature integration and defining a graphical structure model; using label sampling to train the graphical structure model; then using the trained graphical structure model to calculate embedded vectors and a predicted probability for same after multiple iterations of nodes in the hidden feature space, and on the basis of the vectors, performing user transaction control on the nodes.
