PROVEN METHODOLOGY
Our Development & Integration Process
A structured, security-first approach to integrating biometric wallet security into your IoT ecosystem, ensuring robust protection and seamless user experience from day one.
01
Security Architecture & Threat Modeling
We begin with a comprehensive threat assessment for your specific IoT device and use case. Our team designs a layered security architecture incorporating hardware-backed enclaves (like TPM/SE), secure boot, and encrypted communication channels to protect biometric data at rest, in transit, and during processing.

02
Hardware Integration & SDK Development
Our engineers develop custom SDKs and firmware to interface with your device's biometric sensors (fingerprint, facial recognition) and secure elements. We handle the complex cryptography for key generation, storage, and signing operations directly on the device, ensuring private keys never leave the secure enclave.

Smart Contract & On-Chain Logic
We develop and audit the smart contracts that define wallet permissions, recovery mechanisms, and transaction rules. This includes multi-signature schemes, time-locks, and social recovery logic that are triggered by verified biometric actions, creating a secure and user-friendly custody model.

End-to-End Testing & Audits
Every component undergoes rigorous testing: unit tests for contracts, penetration testing on device firmware, and integration tests simulating real-world attack vectors. We facilitate third-party audits from reputable firms before mainnet deployment to provide an external trust seal.

IoT Biometric Security: Common Questions
Get clear answers on timelines, security, and process for integrating biometric wallets into your IoT devices.
A standard integration for a new IoT device line takes 4-6 weeks from kickoff to production-ready firmware. This includes hardware attestation setup, biometric sensor integration, secure enclave provisioning, and end-to-end testing. For adding biometric security to an existing certified device, deployment can be as fast as 2-3 weeks.
