About
The problem it solves Sybil attacks and bot farms are major threats in the Web3 ecosystem. Current verification methods are often too expensive or lack real-time validation. Secure Liveness Verifier is a lightweight, real-time biometric authentication tool designed to verify "Proof of Personhood" before a user can interact with a smart contract on Base.
How it's made
Challenges we ran into Calibrating the sensitivity of the AI to detect blinking and head movements accurately under different lighting conditions was challenging, but i managed to optimize the TensorFlow model for better responsiveness.
