idOS v1 KYC Credential Schema: A Comprehensive Guide

Overview

In the rapidly evolving landscape of digital identity verification, the need for a standardized and universally applicable KYC (Know Your Customer) credential schema has become increasingly pressing. idOS v1 aims to address this challenge by designing a KYC Credential Schema that not only maximizes reusability across multiple use cases but also satisfies various regulatory requirements. This article provides an in-depth exploration of the idOS v1 KYC Credential Schema, its implementation decisions, and the updated properties that form the foundation of this innovative solution.

Implementation Decisions

The idOS v1 KYC Credential Schema is built upon several key implementation decisions that ensure its flexibility, scalability, and compliance with regulatory standards.

Signature & Verification

The idOS SDK must generate and verify JSON-LD credentials using Ed25519Signature2020 signatures. This ensures that the credentials are securely signed and verified, providing a high level of assurance and trust in the identity verification process.

Document Resolution

The SDK should not hardcode document-resolver dependencies (e.g., Fractal, etc.). This allows for greater flexibility and adaptability in the credential schema, enabling it to be easily integrated with various document resolution services.

Library Choice

Digital Bazaar's library will be used for issuance and verification, with dynamic document loader support. This library provides a robust and reliable foundation for the credential schema, ensuring that it can handle complex verification processes with ease.

Schema Resolution

The idOS KYC Credential schema will be shipped by default within the SDK. The default document loader resolves the idOS credential schema from a static URL. Integrators can extend this mapping dynamically for custom schemas, allowing for seamless integration with various use cases.

Issuer Resolution

Accepted issuers must be manually configured via a Document Loader. idOS will publish a list of authorized data issuers in the documentation, ensuring that only trusted and compliant issuers are integrated into the credential schema.

Issuer Representation

Issuer representation can be either a URL format with multibase key (e.g., https://vc-issuers.verifier.id/keys/1#zN...) or a document loader that fulfills the role of discovering the right key controller document. This allows for flexibility in issuer representation, enabling issuers to choose the most suitable format for their needs.

Documentation Requirements

Issuers must specify how their VerificationMethod (keys) should be represented. Issuers must also publish a document loader to allow others to integrate their representation, ensuring that the credential schema remains transparent and accessible.

The idOS v1 KYC Credential Schema includes a comprehensive set of updated properties that provide a robust and reliable foundation for identity verification. These properties include:
