Embodiment Construction

[0029] In order to enable those skilled in the art to better understand the technical solutions in this specification, the technical solutions in the embodiments of this specification will be clearly and completely described below in conjunction with the drawings in the embodiments of this specification. Obviously, the described The embodiments are only some of the embodiments in this specification, not all of them. Based on the embodiments in this specification, all other embodiments obtained by persons of ordinary skill in the art without creative efforts shall fall within the protection scope of this specification.

[0030] As mentioned above, the current user identity authentication mainly adopts static security authentication methods, such as fingerprint authentication, face authentication, password authentication and so on. In this way, the static authentication information is fixed, once stolen, it will lead to more serious consequences. In addition, this method also r...

Abstract

The embodiment of the invention provides an abnormity detection model updating method and device and electronic equipment. The method comprises: obtaining user time sequence behavior characteristics collected by terminal equipment of a target user; inputting the user time sequence behavior characteristics into an anomaly detection model deployed for the target user, and obtaining an exception detection result of the exception detection model for the user time sequence behavior characteristics, wherein the abnormity detection model is obtained by training based on historical user behavior timesequence characteristics of the target user in at least one terminal device and corresponding tags, and the tags comprise user behavior anomalies and user behavior non-anomalies; and if the anomaly detection result indicates that the user behavior is non-abnormal, performing iterative training on the anomaly detection model based on the user behavior time sequence feature and the label with the non-abnormal user behavior.

Description

technical field [0001] This document relates to the field of artificial intelligence technology, and in particular to an anomaly detection model updating method, device and electronic equipment. Background technique [0002] Current user identity authentication mainly adopts static security authentication methods, such as fingerprint authentication, facial authentication, password authentication, and the like. In this way, the static authentication information is fixed, once stolen, it will lead to more serious consequences. In addition, this method also requires the user to cooperate with the operation. For example, the password authentication requires the user to enter the password information, which is not convenient enough for the user and affects the user experience. [0003] In view of this, there is an urgent need for a more user-friendly and reliable security authentication method. Contents of the invention [0004] The purpose of the embodiments of this specific...
