PoH improves security by using palm biometrics, leveraging zero-knowledge proofs, and protecting sensitive data via decentralized storage.

This combo counters bots, fraudulent identities, and unauthorized access across various high-security scenarios.

💼 High-Security Document Access
➡️ Challenge: Stolen credentials can lead to data leaks of sensitive files (finance/law/research)
➡️ Solution: Files are only accessible to an on-chain verified DID. A user attempts access, their palm is scanned, verifying they’re authorized.

⬇️

Preventing E-Commerce Fraud
➡️ Challenge: Fraudulent transactions with bots or stolen identities.
➡️ Solution: At checkout, require a one-time palm-authentication linked to the user’s decentralized ID. This ties each purchase to a confirmed human,  reducing fraudulent orders

⬇️

🗳️ Protecting Online Voting
➡️ Challenge: In DAO governance or digital elections, bots/fake accounts can distort the results.
➡️ Solution: Require a unique palm-recognition credential for each vote, ensuring each participant is a real human. ZKPs preserve voter privacy

⬇️

🪪 KYC Without Risking Privacy
➡️ Challenge: KYC checks can expose user info to hacking/misuse
➡️ Solution: Through zero-knowledge proofs, users prove they meet requirements (e.g., age, jurisdiction) without sharing raw personal data. Also, no risk of data leaks!

⬇️

🏢 Workplace Authentication
➡️ Challenge: Fraudulent check-ins, buddy punching,  unauthorized logins can compromise enterprise security
➡️ Solution: Scan a unique palm print+vein, each employee securely verifies their identity. The system can lock out unverified personnel

⬇️

📍 DePIN Networks 
• Challenge: Shared devices, co-working spaces, or vehicle fleets can be abused
• Solution: Humanity Protocol’s verified-human system lets only real, unique participants access these physical assets, preventing multiple fraudulent sign-ups

🔐 Secure Access to Sensitive Facilities
➡️ Challenge: Conventional access badges or PIN codes can be stolen or shared.
➡️ Solution: Palm-verification devices, allowing only verified individuals to enter. Credentials are decentralized = there’s no single database to breach.
