# Terms & Definitions

## **Terms and Definitions**

<table><thead><tr><th width="195">Term</th><th>Definition</th></tr></thead><tbody><tr><td>Agent</td><td>Describes the software assisting users in managing, storing, and exchanging their credentials through protocol-defined controllers.</td></tr><tr><td>Attribute</td><td>Descriptive data about a characteristic of a Subject (e.g., date of birth).</td></tr><tr><td>Claim</td><td>An assertion made or declared about a subject.</td></tr><tr><td>Entity</td><td>A person who assumes a role in the myBID ecosystem. (e.g., Issuer, Verifier or Holder).</td></tr><tr><td>Data minimisation</td><td>Minimal required data to successfully accomplish a task.</td></tr><tr><td>Decentralized identifier (DID)</td><td>A globally unique persistent identifier generated and/or registered cryptographically in a VC based wallet.</td></tr><tr><td>Decentralized identifier document</td><td>Accessible data using a verifiable credential registry that contains information related to a specific DID. It is also known as a DID document (DIDComm) and is analogous to public key information.</td></tr><tr><td>Holder</td><td>An entity that holds a credential and asserts claims on a credential by forming presentations.</td></tr><tr><td>Identity Hub</td><td>A secured cloud-based off-chain decentralized storage for securing and controlling personal data by data owners themselves. They allow users to store and control their sensitive data with their Web3 Identity wallet.</td></tr><tr><td>Independent Identity Provider (IDP)</td><td>Open standard decentralized authentication protocol that uses OAuth 2.0 to grant access tokens.</td></tr><tr><td>Issuer</td><td>A role an Entity can perform by asserting claims about subjects to create verifiable credentials, and transmitting the credential to a Holder.</td></tr><tr><td>myBID, MBID or myBID Token</td><td>Represents the MyBID token.</td></tr><tr><td>Presentation</td><td>Data organized by assertion of claims on verifiable credentials for the purpose of presentation to verifying entities. Tamper-resistant and encoded with cryptography.</td></tr><tr><td>Selective Disclosure</td><td>Function of limiting data exposure for sharing and verification.</td></tr><tr><td>Subject</td><td>A thing or person about which claims are made. In the context of myBID, it can be synonymous with the Holder.</td></tr><tr><td>Validation</td><td>A process to ensure tamper-proof credential and valid assertion of claims by verification.</td></tr><tr><td>Verifiable Credential</td><td>A tamper-resistant credential with embedded data such as authorship that can be cryptographically verified. It forms the basis for verifiable presentations.</td></tr><tr><td>Verifiable Data Registry</td><td>The blockchain ledger that supports the creation, definition, revocation, and verification of credentials.</td></tr><tr><td>Verifier</td><td>A role of an entity that is processing and tries to confirm a certain credential's validity.</td></tr><tr><td>URI</td><td>A Uniform Resource Identifier, as defined by [RFC3986].</td></tr></tbody></table>
