DIDs are unique global identifiers that allow an entity to control its digital identity without the need for a central authority. They facilitate a more secure and private web.
A DID consists of three main parts: the scheme (always did:), the DID method (which indicates the specific technology or protocol used), and the DID’s unique identifier.
It is a JSON document that contains information associated with a specific DID, including public keys, services, and other metadata necessary for secure interaction in digital environments.
DIDs are based on principles of decentralization, interoperability, security through cryptographic proofs, and user control over their own identity.
DIDs enable identity verification using cryptographic technology and distributed ledgers, eliminating the need for intermediaries in the authentication process.
DID methods are a set of rules and procedures that define how DIDs are created, resolved, and managed within a specific system or technology.
The subject is the entity identified by the DID, while the controller is the entity with permissions to modify the subject’s DID Document.
Resolvers are tools that allow obtaining the DID Document from a DID, and registries are systems that store and allow the management of DIDs and their associated documents.
DIDs are created using a specific DID method, following the rules and procedures defined for that method, and are usually registered in a distributed ledger system like blockchain.
Security is ensured through the use of advanced cryptography, and privacy is secured by allowing users to control what information they share and with whom, using selective data disclosure.
Yes, DIDs can identify not only individuals but also organizations, devices, and applications, offering a wide range of applications in different contexts.
DIDs have applications in authentication, digital signing, identity management, permission systems, and any scenario requiring secure and verifiable identification. At Extrimian, we provide solutions to unleash the potential of DIDs, proposing solutions that address everything from authentication, information verification to data interoperability among different platforms and services.
DIDs are expected to play a crucial role in the development of a more secure and privacy-oriented internet, promoting the adoption of decentralized digital identities across various sectors.
