An integrated authentication and payment infrastructure built on digital identity
Crosshub is built on digital identity
connecting authentication, payments, and additional security layers into a single, seamless flow
A technology architecture focused on scalability, integration, and real-world operation
Technology designed for real service environments
- Each technology is designed as an independent authentication and security layer, forming a unified service flow centered on digital identity
- Authentication and verification are separated by role, allowing flexible operation across different service environments
- Every technical component is selected based on its suitability for real-world deployment and long-term operational scalability
We prioritize systems that operate reliably in the real world, over theoretical or experimental possibilities
Core Technology Stack
Identity Verification Infrastructure
Built on an identity infrastructure designed around IDBlock-based identity issuance and verification
- A structure that separates identity issuance and verification to enhance security and system stability
- Verification mechanisms designed to ensure the integrity of authentication results
- API architecture that enables services to integrate based on IDBlock authentication outcomes
By separating identity issuance and verification, we deliver a digital identity infrastructure that balances security and scalability
4.1 Generation Hybrid DID
A DID architecture that supports both Web2 and Web3 environments, built for practical deployment in real-world services
- Support for both Web2 and Web3 environments
- An architecture designed for seamless integration with existing service systems
- A structure that connects passport-based offline identity with digital identity
The 4.1 Generation Hybrid DID preserves the strengths of decentralized identity, while ensuring practical applicability in live service environments
ZKP-Based Identity Verification
An authentication method that leverages Zero-Knowledge Proofs (ZKP) to verify only required conditions while minimizing personal data exposure
- Selective proof of required conditions such as age or eligibility
- A verification process that does not directly transmit personal data during authentication
- Ability to confirm verification results without exposing underlying identity information
ZKP-based verification delivers a balanced approach to privacy protection and authentication trust
SSI (Self-Sovereign Identity)
SSI (Self-Sovereign Identity) enables users to directly control and manage their own identity
- An identity structure where control resides with the user, not a centralized server
- Reuse of verified identity across services without repeated submissions
- Reduced reliance on centralized identity systems
SSI moves identity usage away from repetitive submissions, enabling a user-centric identity ecosystem
AI-Based Identity Matching
AI-powered identity verification validates users and ensures trust throughout the authentication process
- LightGBM-based hybrid AI identity verification
- AI facial recognition as a secondary security layer
- Detection of fraud such as identity theft or duplicate issuance
AI functions as a core verification layer, responsible for authentication accuracy and security trust
AI Voice-Based Additional Authentication
AI voice analysis is used as an authentication factor to reinforce identity assurance during high-risk actions
- Real-time voice analysis by AI to enhance authentication trust
- An additional security layer applied after primary identity verification
- Extra authentication for sensitive actions such as payments and transfers
Voice AI operates as an additional security layer designed to strengthen overall authentication reliability
Technology trust validated by external proof
We demonstrate trust through real-world deployments and external validation
Closing
A service infrastructure that scales on authentication and security
Crosshub’s technology is a service infrastructure where authentication, security, and payment functions are unified around digital identity
