🔎Core Concepts

The core concept of didPass is the Triangle of Trust, a three-party system for verifying digital identities. Let's explore!

The core concept of the didPass (DID Passport) is called the "Triangle of Trust" which involves three key modules as defined by the World Wide Web Consortium (W3C): Holder, Issuer, and Holder. These modules work together to make sure everything is secure and trustworthy.

didPass - Triangle of Trust

• Holder — The person or organization that receives and stores the digital credentials issued by the Issuer. The Holder has control over their credentials and can choose to share them with Verifiers when needed. For example, a person who receives a digital diploma from a university would be the Holder of that credential.

• Issuer — The Issuer is the organization or agency that creates and gives the Holder digital or verifiable credentials. These credentials contain information about the Holder, like their identity, qualifications, or membership. For example, a government agency could be an Issuer that issues digital driver's licenses or passports to individuals; a university could be an Issuer diploma.

• Verifier — The organization or entity that checks the authenticity and validity of the digital credentials presented by the Holder. Verifiers rely on the credentials issued by trusted Issuers to establish trust in the information provided by the Holder. For example, an immigration officer verifies a traveler’s passport, an employee verifies an applicant's diploma; and a bank verifies a client’s national identity.

didPass (DID Passport) of "Triangle of Trust" ensures that digital credentials come from reliable sources (Issuers), are managed by the individuals (Holders), and can be confirmed by trusted entities (Verifiers) to facilitate secure, private, and trustworthy digital identity transactions.
