Episode notes
ADVICE

Start Small But Aim For 3-2 Backup Rule

  • Do aim for the 3-2 backup rule but start with just one reliable copy if that's all you can do.
  • Rich stresses that even moving from zero to one backup places you ahead of most people.
INSIGHT

On‑Device Voice IDs Can Stop Bot Fraud

  • Voice biometrics can confirm 'human vs bot' and approximate age with seconds of audio, enabling platforms to reduce bot-driven fraud.
  • Helix runs on-device only, avoiding central biometric databases to protect privacy.
ADVICE

Replace CAPTCHAs With Better Biometric Checks

  • Do consider replacing CAPTCHAs and SMS checks with on-device biometric checks to make verification easier for humans and harder for bots.
  • Helix positions voice checks as the 'first wedge' to remove CAPTCHAs and insecure SMS.
