Whenever public sentiment or fan competitions are on the line, bad actors inevitably attempt to rig the outcome. Traditional online polling utilities rely on rudimentary mechanisms—such as writing a single cookie or checking the raw client IP address. Against automated headless browsers, rotating residential proxies, and VPN swarms, these legacy defenses collapse in minutes.
Why Cookies and Raw IPs Are Not Enough
In the modern web, an automated script can wipe its cookies between HTTP requests with a single line of code. Similarly, with mobile cellular data and dynamic IP allocation, thousands of legitimate users can share a single corporate NAT or carrier IP gateway. Conversely, an adversary with access to a residential proxy network can rotate across 50,000 distinct IP addresses within a single hour.
Multi-Factor Entropy Fingerprinting
To defend poll integrity without requiring voters to create accounts, PollFlux utilizes multi-layered client entropy analysis. When a ballot is submitted, our client scripts evaluate browser characteristics: Canvas rendering artifacts, WebGL hardware capabilities, audio context processing latency, available font families, and screen geometry. These factors are synthesized into an encrypted, one-way cryptographic hash that remains persistent across private browsing sessions.
Sliding Window Cooldowns & Turnstile Integration
Combined with server-side sliding-window rate limiters and invisible Cloudflare Turnstile cryptographic challenges on suspicious traffic spikes, PollFlux effectively neutralizes bot swarms while allowing honest attendees to participate seamlessly.
