Privacy & Security Architecture

Privacy & Security Architecture

At the core of InterLink ID lies a multi-layered privacy architecture, purpose-built to secure human identity while preserving decentralization and usability. This architecture brings together three critical pillars: encrypted biometric data, decentralized storage, and zero-knowledge proof readiness. Together, they form the technological backbone that ensures users retain full control over their identity, without compromising security or privacy.

Encrypted Biometric Data

InterLink ID begins with the biometric verification of real humans — a critical step in establishing Proof of Personhood. But unlike traditional identity systems, InterLink encrypts all biometric data at the moment of capture using end-to-end cryptographic methods. This ensures that:

• No raw biometric information is ever stored or exposed.

• Only the encrypted version of identity data exists, ensuring that even in worst-case scenarios (e.g. data breaches), user privacy remains protected.

• The encrypted data can be referenced for verification without revealing the original input.

This approach enables both privacy and integrity — the system knows you’re real, but it doesn’t need to know who you are.

Decentralized Storage

To eliminate centralized points of failure, InterLink ID stores all identity-related data across decentralized storage layers. By integrating with decentralized file systems (e.g. IPFS or Arweave), the platform guarantees:

• Tamper-resistance: no single entity can alter or delete user identity records.

• High availability and fault tolerance.

• User data remains sovereign and censorship-resistant.

This decentralized approach aligns with our self-sovereign identity model and ensures that InterLink ID operates without relying on any central server or third-party authority.

Zero-Knowledge Proof Readiness

As InterLink evolves, privacy technology must evolve with it. That’s why the system is designed to be fully zero-knowledge proof (ZK) compatible. ZK cryptography allows users to prove statements — such as their uniqueness or access rights — without disclosing the underlying data. In practice, this means:

• Users can verify their personhood without exposing their biometrics.

• Selective disclosure becomes possible (e.g., proving you are over 18 without revealing your birthdate).

• Secure participation in on-chain voting, governance, and mini-app access without revealing wallet or identity details.

While full ZK integration may roll out progressively, the current infrastructure is ZK-ready by design. This future-proofs InterLink ID for a privacy-centric Web3.

Together, these three elements ensure that InterLink ID is not just a verification layer — but a trust layer, enabling the next generation of human-first decentralized applications.
