AI Technical Summary

Technical Problem

Existing technologies are insufficient to effectively prevent IP sniffing attacks using WebRTC technology. Traditional privacy protection methods cannot cope with dynamic fingerprint detection, and the lack of real-time monitoring mechanisms leads to the risk of user privacy leaks.

Method used

Intercept ICE protocol interaction data packets at the browser kernel layer, generate fake IPs and replace real IPs, build a comprehensive fingerprint database, use IPHash, URLHash and completely random modes for fingerprint transformation, and monitor and remedy in real time.

Benefits of technology

It effectively prevents IP sniffing attacks, enhances fingerprint camouflage and anti-detection capabilities, achieves a closed-loop security protection system across the entire chain, and promptly detects and remedies privacy leaks.

Abstract

This invention discloses a method for hiding WebRTC IPs in a browser, relating to the field of network security technology. This invention intercepts ICE protocol interaction data packets at the kernel layer and, through a fake IP generation and replacement mechanism, overcomes the limitations of traditional VPNs that only protect at the application layer, effectively preventing IP sniffing attacks using WebRTC technology. It innovatively adopts a dynamic fingerprint combination strategy, constructing a comprehensive fingerprint database with three flexible transformation modes to avoid fixed fingerprint templates being marked as spoofed fingerprints, significantly improving the concealment and anti-detection capabilities of fingerprint spoofing. Furthermore, this invention is equipped with a real-time monitoring and anomaly remediation mechanism, which can promptly detect IP leaks or fingerprint anomalies and automatically restart the protection process, forming a closed-loop protection system of interception-spoofing-monitoring-remediation, providing users with a more secure and stable network privacy protection solution.
