FilPass Custom Verifier

Watch: How to Use the Custom Verifier

To better understand how the Custom Verifier works, watch the video below:

Overview

The FilPass Custom Verifier is a feature designed to give institutions full control over how their issued credentials are verified. While the system continues to support OpenCerts for standard credential validation, the Custom Verifier introduces a more flexible and institution-specific approach.

With this feature, organizations can verify not only blockchain-based certificates but also PDF versions of credentials, ensuring a more comprehensive and accessible verification experience for recipients and third parties.

Importance of Custom Verifier

The Custom Verifier addresses key limitations in traditional verification systems and introduces several important benefits:

• Institution Ownership & Control
  Each institution verifies only its own issued credentials, preventing cross-verification between unrelated organizations.
  
• Support for Multiple File Types
  Unlike default verification methods, the Custom Verifier supports both:
  • OpenCerts files
  • PDF certificates
    
• Improved Trust & Accuracy
  By restricting verification to the issuing institution, the system ensures higher authenticity and reliability of results.
  
• Better User Experience
  Recipients with multiple credentials from different institutions can rely on each organization’s dedicated verifier for accurate validation.

How It Works

1. Default Behavior (OpenCerts)

• The system uses OpenCerts as the default verifier.
• Users can verify OpenCerts-issued documents through the OpenCerts verification page.
• Limitation: PDF documents cannot be verified.

2. Using the Custom Verifier

• Each institution is assigned its own Custom Verifier.
• The verifier is configured to recognize and validate only that institution’s credentials.

3. Verification Scenarios

• Verifying OpenCerts Files ✅
  • The Custom Verifier can successfully verify OpenCerts documents issued by the institution.
• Verifying PDF Certificates ✅
  • The Custom Verifier enables verification of PDF certificates, something not supported by OpenCerts alone.
• Verifying External Documents ❌
  • If a document from another institution is uploaded:
    • The system will display: “certificate can't be loaded”
  • This ensures that only valid, institution-issued credentials are recognized.
