I. FAQs (SSI)
- What is Digital Identity? Digital Identity represents individuals, organizations, or devices in the digital world. It encompasses various forms of online identification, from usernames and social media profiles to certificates and digital credentials.
- What is Self-Sovereign Identity? Self-Sovereign Identity is an approach to digital identity management where control is entirely in the hands of individuals or entities, allowing them to own, control, and share their personal information securely and efficiently.
- How does SSI differ from the current digital identity system? Unlike the current system, where third parties like social platforms or service providers control digital identity, SSI returns control to the user, eliminating intermediaries and reducing dependence on centralized entities.
- What are the main contrasts between federated and decentralized identities? Federated identity systems rely on trusted intermediaries for authentication, whereas decentralized identity systems eliminate intermediaries, thereby enhancing security and privacy.
- What are the fundamental principles of SSI? Principles include decentralization, user control, privacy, security through cryptographic proofs, interoperability, portability, simplicity, and extensibility.
- How is SSI applied in real life? SSI can be applied in various contexts, such as age verification, residence, educational credentials, medical histories, and more, using verifiable credentials to share information securely and privately.
- How does SSI improve user privacy? By giving users direct control over who can access their personal information and the ability to reveal only the data necessary for a specific interaction.
- Does SSI require the use of blockchain? Yes, SSI utilizes blockchain technologies to decentralize identity control, ensuring the integrity and security of verifiable credentials.
- What are Decentralized Identifiers (DIDs)? DIDs are unique and globally resolvable identifiers not tied to any central authority. They allow users to establish and control their digital presence independently, enhancing autonomy over their digital identities.
- What are Verifiable Credentials (VCs)? VCs are digitally issued claims by trusted entities and cryptographically signed. They represent various types of information and enable users to demonstrate specific attributes about themselves without revealing excessive personal details.
- Why are Verifiable Credentials important in the SSI ecosystem? They allow for the verification of information without the need to reveal unnecessary personal data, promoting privacy and data security.
- Who can issue Verifiable Credentials? Any trusted entity, such as governments, educational institutions, health organizations, and businesses, can issue verifiable credentials within the SSI ecosystem.
- What is “Selective Disclosure”? It is a feature of SSI that allows users to reveal only the information necessary for a transaction or verification, protecting their privacy.
- What role does Extrimian play in digital identity? Extrimian offers solutions aligned with decentralized and self-sovereign identity paradigms. Its products focus on the management, verification, and authentication of identities, designed to enhance user security, privacy, and autonomy in the digital world.
