Abstract

The invention provides a method and a device for detecting abnormal use of an account. The method for detecting the abnormal use of the account comprises the steps of obtaining first behavior characteristic data of a to-be-detected account, wherein the first behavior characteristic data is behavior characteristic data corresponding to first historical behavior data executed for the to-be-detectedaccount in a long time period; acquiring second behavior characteristic data of the to-be-detected account, the second behavior characteristic data being behavior characteristic data corresponding tosecond historical behavior data executed for the to-be-detected account in a short period of time, and the end time of the short period of time being not earlier than the end time of the long period of time; then, providing the first behavioral feature data and the second behavioral feature data to an account anomaly detection model to determine whether usage for the account is abnormal. By utilizing the method, the account use abnormality is detected by using the long-term accumulation behavior and the short-term sudden behavior for the to-be-detected account, so that the account security canbe improved.

Description

technical field [0001] The present disclosure relates to the field of the Internet, and in particular, to a method and device for detecting abnormal use of accounts. Background technique [0002] With the continuous development of Internet technology, more and more users use Internet accounts for work and life activities.
