Common browser cheating plug-insCan identify common cheating plug-in risks
Security and StabilityCode ProtectionThe device fingerprint SDK and JS have code protection mechanisms (such as VMP), which effectively resist black hat cracking attempts to manipulate code logic and falsify data✅ (VMP)
DowngradeIntercepting and sending collection requests in the Web environment can still generate device fingerprints normally
Anti packet captureWeb (including iOS and android web) have the ability to prevent packet capture
