1. Project Introduction

BioHash is Softstack GmbH’s pioneering project that merges AI-driven facial recognition with blockchain technology for secure digital verification. Operating cross-platform as a web app, BioHash offers a seamless, app-free experience on mobile devices and computers.

2. A Smile Away from Secure Access

BioHash simplifies digital verification. Users can log in by opening the app and smiling into the camera. This process registers them and enables easy future logins by simply smiling. The user-friendly design ensures quick and intuitive authentication for digital applications.

3. Secure by Design – Privacy First

BioHash prioritizes data protection by leveraging cryptographic hash functions, ensuring that no images or personal data are ever stored. To further enhance security and privacy, the system integrates Multi-Party Computation (MPC) and Zero-Knowledge Proofs (ZKPs), enabling secure verification without revealing any underlying user data. This architecture protects users from data breaches by eliminating centralized data storage and provides a decentralized, Web3-based cryptographic security layer built for trustless environments.

4. Merging AI with Web3 Technology

BioHash combines AI and blockchain to enable secure, decentralized biometric verification. AI is used for real-time fraud protection, while cryptographic techniques ensure data integrity and privacy-compliant authentication.

The Future of Inclusive, Privacy-First Verification

BioHash is reshaping digital identity by offering a verification solution that is as inclusive as it is secure. Designed for accessibility, BioHash works on any device with a camera, no app installations or complex onboarding required. By fusing advanced AI with Web3 technologies, the system enables fast and frictionless user verification while actively protecting against fraud in real time. What sets BioHash apart is its privacy-by-design architecture. No biometric images or personal data are ever stored. Instead, BioHash uses cryptographic hash functions combined with Multi-Party Computation (MPC) and Zero-Knowledge Proofs (ZKPs) to validate identity securely without ever exposing or revealing sensitive information. This decentralized, trustless infrastructure not only ensures data integrity but also future-proofs compliance with global privacy standards like GDPR.

BioHash isn’t just an upgrade to legacy KYC methods it’s a paradigm shift toward truly sovereign identity. Inclusive, privacy-preserving, and secure by default.
