Account abnormal detection method and device

Abstract

The invention discloses an account abnormity detection method and an account abnormity detection device. According to the embodiment of the invention, a server monitors an operation event triggered based on an account after log-in, and at least one operation path mapped by the operation event is acquired; according to the acquired operation path, a log-in abnormity value corresponding to the account is calculated; historical data corresponding to the account are called to acquire a historical reference value corresponding to the historical data; and according to the historical reference value, when the log-in abnormity value is recognized to meet a preset rule, the account is detected to be abnormal. Compared with a mode of purely comparing the log-in place of the account at the time and a commonly-used log-in place in the prior art, the method of the embodiment of the invention improves the information abnormity detection accuracy.
