Introduction
What is vouch?
vouch enables businesses to verify user-owned data stored on internet platforms without accessing or storing the sensitive data itself. Users generate cryptographic attestations directly on their devices, preserving privacy while ensuring secure verification.
Consider common scenarios where businesses need to verify user data from external platforms:
- A lending platform needs to verify identity and business credentials without documents. See example →
- An employer wants to confirm real candidates with cryptographic proof. See example →
- A brand agency needs to validate social presence and audience metrics securely. See example →
Traditional approaches require either direct API access or users sharing sensitive credentials. vouch provides a third option: cryptographic proof generation.
Implementation Overview
- Create a business account with vouch to start receiving verifiable user claims.
- Integrate vouch into your application flow based on your verification needs with our API. Test and go-live.
- Receive attestations when users complete the verification process.
Platform Availability
vouch operates seamlessly across multiple end-user platforms to maximize accessibility and adoption. The platform supports three distinct verification flows to accommodate different user contexts: desktop, mobile, and cross-device.
Desktop Applications: The vlayer browser extension enables desktop verification workflows within existing web applications.
Mobile Applications: Native iOS and Android applications provide optimized mobile verification experiences. Users on mobile devices complete verification using their device's native capabilities and return seamlessly to your application.
Seamless Mobile Integration: Mobile users can complete the verification process without installing additional apps. The flow appears as a native overlay on their device, preserving context and delivering a smooth experience.
Cross-Device Applications: Desktop users can initiate verification by scanning a QR code with their mobile device, leveraging mobile-specific verification capabilities while starting the process on desktop.
