AI Technical Summary

Technical Problem

In existing technologies, user login systems lack security, user information is stored inconsistently, and user passwords are easily stolen, leading to problems with system security and the integrity of information retrieval.

Method used

By encrypting usernames, IP addresses, and protocol IDs to generate information strings, calculating the similarity of user information sets, limiting the interval between username and password changes, and dividing into whitelists and blacklists, the security and consistency of user information are ensured.

Benefits of technology

It improves the security of the user login system, ensures the integrity and consistency of user information, prevents password leakage and unauthorized login, and optimizes the information storage and retrieval process.

Abstract

This invention provides a data processing system for obtaining abnormal user login information. By acquiring a first set of information strings, when a login request from any first user is detected, a second set of user information is acquired, thereby acquiring a third set of user information corresponding to a third user identifier identical to the second user identifier. Then, the similarity between the second and third user information sets is calculated. When the similarity between the second and third user information sets is greater than or equal to a preset second information string similarity threshold, a login success message is sent to the target user's server in response to the login request. In other words, this application not only determines whether a user can log in to the system based on the username and password, but also based on the user's access IP address and the client IP address used to access that IP address, thus improving the system's security.
