Your brain is your passport.

Brainwave entropy during AI sessions as decentralized identity. No iris scans. No stored biometrics. No proprietary hardware.

H(X) = 1.847 bits GF(3) = 0 did:gay:*

Problem

Iris scanning is already banned in 12+ countries.

WorldID requires proprietary Orb hardware, stores biometric iris templates, and has been ordered to delete data across multiple continents. Thailand demanded deletion of 1.2M+ iris scans. Kenya barred all biometric collection. The Philippines cited DPA violations. GDPR investigations in Germany, Spain, Portugal. Centralized infrastructure. Binary classification. The "real human network" is shrinking.

Solution

Proof of Brain: your cognitive fingerprint.

passport.gay uses Shannon entropy of EEG band powers during LLM sessions as identity. Your brain's unique response patterns during conversation with AI create an unreplicable, continuous proof of personhood.

Features

What WorldID can't do.

Continuous Auth

Every session re-proves identity. No one-time enrollment. Your brain is verified while you work.

Template Revocability

Compromised template? Change cognitive task, get a new one. Try that with your iris.

Coercion Detection

Stress measurably alters EEG patterns. Forced authentication is detectable. Iris scans can't tell.

No Stored Biometrics

Entropy is computed in real-time, never stored. Only the SHA-256 commitment goes on-chain. GDPR-native.

GF(3) Triadic Identity

Not just human/bot. Three cognitive states: Generator (+1), Ergodic (0), Validator (-1). Richer than binary.

Diffusion Model Defense

1/f spectral analysis detects synthetic EEG from GANs, VAEs, and diffusion models. Real brains have pink noise.

Landscape

Identity is a spectrum.

Every identity project treats personhood as a gate. None center joy, expression, or color. passport.gay is the only system where your identity is something you celebrate.

Theory

Gärdenfors Conceptual Spaces

Identity lives in a geometric space of quality dimensions. Browser fingerprints give ~70 bits (Canvas, WebGL, UA). Brainwaves give 82 bits (δ, θ, α, β, γ). Together: an 11-dimensional conceptual space where GF(3) prototypes define a Voronoi tessellation. Your identity is the convex hull of your trajectory through this space.

Criterion P (Gärdenfors): A natural property is a convex region in a conceptual space. GF(3) Voronoi tessellation yields 3 convex cells from 3 prototypes — the simplest non-trivial categorization that supports a conservation law. Browser fingerprints are passively extractable (~70 bits without consent). Brainwave entropy requires active participation. passport.gay binds both in one space.

Architecture

Three pillars of identity.

Browser fingerprints are passive. Brainwaves are biological. Interaction entropy is behavioral. passport.gay fuses all three into a single identity space. No single pillar is sufficient alone — but together they create an identity that is continuous, revocable, and uniquely yours.
