Canvas fingerprinting relies on subtle variations in GPU hardware, display drivers, and rasterization algorithms. When a browser executes 2D canvas drawing calls, tiny mathematical differences produce an identical, tracking-resistant hash without accessing system storage.
How Do WebRTC STUN Leaks Expose Your IP?
WebRTC creates real-time media streams across browsers. To establish peer-to-peer tunnels through firewalls, it contacts STUN servers. Misconfigured browser clients will return your physical ISP interface address, bypassing VPN adapters.
Why Encrypted DNS (DoH) Matters
DNS-over-HTTPS encrypts domain lookups over port 443. Without DoH, your internet service provider or public Wi-Fi operator can log every domain you visit using cleartext UDP port 53 traffic, even when browsing with full TLS encryption.
What Triggers Anti-Fraud & Bot Flags?
Web fraud systems evaluate client contradictions. If your user-agent reports Windows NT but your WebGL renderer unmasks an Apple M-series GPU, or if your browser getter functions show prototype tampering, anti-bot algorithms immediately flag the session.
Hardware AudioContext Profiling
Audio fingerprinting processes an unrendered audio signal through dynamic compression filters. Slight mathematical floating-point variations in audio hardware architectures produce unique waveform sums that track client devices without local storage access.
Spectre Mitigations & Timer Clamping
High-resolution timers like performance.now() can be exploited to construct side-channel cache attacks. Modern browsers clamp timer precision to ≥ 20μs and isolate cross-origin execution contexts to prevent memory boundary leaks.
