Decentralized Identifiers
Decentralized identifiers (DIDs) are a type of globally unique identifier that enables an entity to be identified in a manner that is verifiable, persistent (as long as the DID controller desires), and does not require the use of a centralized registry. DIDs enable a new model of decentralized digital identity that is often referred to as self-sovereign identity or decentralized identity. They are an important component of decentralized web applications. DID documents A decentralized identifier resolves (points) to a DID document, a set of data describing the DID subject, including mechanisms, such as cryptographic public keys, that the DID subject or a DID delegate can use to authenticate itself and prove its association with the DID. DID methods Just as there are many different types of URIs, all of which conform to the URI standard, there are many different types of DID methods, all of which must conform to the DID standard. Each DID method specification must define: * ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CRUD
In computer programming, create, read, update, and delete (CRUD) are the four basic operations of persistent storage. CRUD is also sometimes used to describe user interface conventions that facilitate viewing, searching, and changing information using computer-based forms and reports. The term was likely first popularized by James Martin in his 1983 book ''Managing the Data-base environment''. Conceptual Data can be put in a ''location/area'' of a storage mechanism. * The fundamental feature of a storage location is that its ''content'' is both ''readable'' and ''updatable''. * Before a storage location can be read or updated it needs to be ''created''; that is allocated and initialized with content. * At some later point, the storage location may need to be ''destructed''; that is finalized and deallocated. Together these four operations make up the basic operations of storage management known as CRUD: ''Create'', ''Read'', ''Update'' and ''Delete''. Databases The acrony ...

Federated Identity
A federated identity in information technology is the means of linking a person's electronic identity and attributes, stored across multiple distinct identity management systems. Federated identity is related to single sign-on (SSO), in which a user's single authentication ticket, or token, is trusted across multiple IT systems or even organizations. SSO is a subset of federated identity management, as it relates only to authentication and is understood on the level of technical interoperability and it would not be possible without some sort of federation. Retrieved 2017-07-03. Management In information technology (IT), federated identity management (FIdM) amounts to having a common set of policies, practices and protocols in place to manage the identity and trust into IT users and devices across organizations. Single sign-on (SSO) systems allow a single user authentication process across multiple IT systems or even organizations. SSO is a subset of federated identity manageme ...

Authentication Methods
Authentication (from ''authentikos'', "real, genuine", from αὐθέντης ''authentes'', "author") is the act of proving an assertion, such as the identity of a computer system user. In contrast with identification, the act of indicating a person or thing's identity, authentication is the process of verifying that identity. It might involve validating personal identity documents, verifying the authenticity of a website with a digital certificate, determining the age of an artifact by carbon dating, or ensuring that a product or document is not counterfeit. Methods Authentication is relevant to multiple fields. In art, antiques, and anthropology, a common problem is verifying that a given artifact was produced by a certain person or in a certain place or period of history. In computer science, verifying a user's identity is often required to allow access to confidential data or systems. Authentication can be considered to be of three types: The first type of auth ...

Authentication Protocols
An authentication protocol is a type of computer communications protocol or cryptographic protocol specifically designed for transfer of authentication data between two entities. It allows the receiving entity to authenticate the connecting entity (e.g. Client connecting to a Server) as well as authenticate itself to the connecting entity (Server to a client) by declaring the type of information needed for authentication as well as syntax. It is the most important layer of protection needed for secure communication within computer networks. Purpose With the increasing amount of trustworthy information being accessible over the network, the need for keeping unauthorized persons from access to this data emerged. Stealing someone's identity is easy in the computing world - special verification methods had to be invented to find out whether the person/computer requesting data is really who he says he is. The task of the authentication protocol is to specify the exact series of steps n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Self-sovereign Identity
Self-sovereign identity (SSI) is an approach to digital identity that gives individuals control over the information they use to prove who they are to websites, services, and applications across the web. Without SSI, individuals with persistent accounts (identities) across the internet must rely on a number of large identity providers, such as Facebook (Facebook Connect) and Google (Google Sign-In), that have control of the information associated with their identity. If a user chooses not to use a large identity provider, then they have to create new accounts with each service provider, which fragments their web experiences. Self-sovereign identity offers a way to avoid these two undesirable alternatives. In a self-sovereign identity system, the user accesses services in a streamlined and secure manner, while maintaining control over the information associated with their identity. Background The TCP/IP protocol provides identifiers for machines, but not for the people and o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Certificate Authority
In cryptography, a certificate authority or certification authority (CA) is an entity that stores, signs, and issues digital certificates. A digital certificate certifies the ownership of a public key by the named subject of the certificate. This allows others (relying parties) to rely upon signatures or on assertions made about the private key that corresponds to the certified public key. A CA acts as a trusted third party—trusted both by the subject (owner) of the certificate and by the party relying upon the certificate. The format of these certificates is specified by the X.509 or EMV standard. One particularly common use for certificate authorities is to sign certificates used in HTTPS, the secure browsing protocol for the World Wide Web. Another common use is in issuing identity cards by national governments for use in electronically signing documents. Overview Trusted certificates can be used to create secure connections to a server via the Internet. A certificate is e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Identity Provider
An identity provider (abbreviated IdP or IDP) is a system entity that creates, maintains, and manages identity information for principals and also provides authentication services to relying applications within a federation or distributed network. Identity providers offer user authentication as a service. Relying party applications, such as web applications, outsource the user authentication step to a trusted identity provider. Such a relying party application is said to be ''federated'', that is, it consumes federated identity. An identity provider is “a trusted provider that lets you use single sign-on (SSO) to access other websites.” SSO enhances usability by reducing password fatigue. It also provides better security by decreasing the potential attack surface. Identity providers can facilitate connections between cloud computing resources and users, thus decreasing the need for users to re-authenticate when using mobile and roaming applications. {{cite web , url = http ...

Decentralized Web
The decentralized web is research program which proposes to reorganize the Internet using peer-to-peer infrastructure rather than centralized data hosting services. Interest in the decentralized web arose due to the lack of trust in network maintenance organizations, due to scandals involving widespread espionage and content control. Proposed mechanisms include decentralized identifiers and distributed ledgers. Decentralized identifiers ''Decentralized identifiers'' are an important part of decentralized web applications. Decentralized identifiers are sometimes encapsulated in "decentralized identifier documents" (referred to as "DIDs"). Decentralized web applications frequently rely on URLs to decentralized identifier documents. The World Wide Web Consortium has several recommendations regarding DIDs. These identity documents are intended to identify any subject (e.g., a person, organization, thing, data model, abstract entity, etc.) that the controller of the DID d ...
