01The Problem

Distinguish human-typed content from AI-generated or copy-pasted text using behavioral biometrics without collecting personally identifiable information.

02Architecture & Solution

Captures keystroke dynamics in the browser, sends encrypted logs to a FastAPI backend. A trained Random Forest classifier analyses the patterns and returns an authorship confidence score. SHA-256 log chaining ensures tamper-proof audit trails.
