Abstract

The invention provides a panic buying type transaction abnormity detection method, system and device and a storage medium, and the method comprises the steps: collecting a panic buying type transaction request log in a business server, wherein the panic buying type transaction request log comprises a user identifier or a device identifier initiated by a transaction request, and a transaction request initiation moment; inputting the collected panic buying type transaction request logs into an anomaly classifier, obtaining a classification result, and obtaining the anomaly classifier through pre-training according to historical panic buying type transaction request logs; and if the classification result is abnormal, executing an exception handling operation. According to the method, the detection speed of abnormal panic buying transactions can be increased by utilizing the anomaly classifier, the anomaly position can be quickly positioned, data support is provided for system emergency processing, malicious panic buying operation is avoided, and the user experience is improved.
