AI Technical Summary

⚠Technical Problem

Existing blacklist technology cannot block illegal requests not on the blacklist in real time, and the IP address blocking factor is too simplistic, making it prone to erroneous blocking and unable to meet the needs of different business scenarios.

⚗Method used

By acquiring multiple normal call samples and call requests from the same request source, their similarity is calculated. Combined with user behavior analysis such as activity, engagement, and value assessment, a similarity threshold is calculated using Euclidean distance. The list of abnormal request identifiers is then dynamically updated to achieve real-time and accurate interception.

🎯Benefits of technology

It achieves real-time and accurate interception of abnormal requests, reduces server data processing volume, improves interception efficiency, and adapts to the needs of different business scenarios.

Abstract

The application provides a service calling method and device, comprising: obtaining a plurality of normal calling samples and a plurality of calling requests initiated by a same request source; calculating the similarity of the plurality of calling requests initiated by the same request source and the plurality of normal calling samples; and responding to the calling request initiated by the request source when the similarity meets a preset similarity requirement. The scheme can realize real-time interception of abnormal requests, and by judging whether the calling request is a normal request, the misjudgment caused by using a calling request for judgment can be avoided.
