Overview#
You will not find a simple, single definition on Identity or Digital Identity. Here are some that we have run across that we think are best:- Digital Identity is a set of attributes related to an Entity. ISO 29115
- Digital Identity is a representation of a set of Claims made by one Party about itself or another Entity.[1]
- Identity is how we keep track of people and things and, in turn, how they keep track of us.[2]
Digital Identity implies that Identification (i.e. that the Entity has been separated from the Anonymity Set) has been performed and the Digital Identity is NOT Anonymous.
Digital Identity has one or more Identifiers which MAY be referred to as Identity Attributes
Context#
Digital Identity exists within a provided context which usually involves a Relationship which might be within one of the Following:Digital Identity Enrollment#
A Digital Identity can be created on the fly when a particular identity transaction is desired (Example: OpenID Connect), or persisted in a Data Store to provide a referenceable Digital Identity representation.Typically when a Digital Identity is created there is a Identity Proofing process
A Digital Identity may be signed by a Digital Identity Provider (IDP) to provide a Level Of Assurance to a Relying Party
Digital Identity, Authentication, Authorization #
Digital Identity, Authentication and Authorization are separate and distinct.Digital Identity are the Claims (Attributes or Identifiers) for a specific entity that provide Identification
Authentication is the process of establishing a Level Of Assurance that the Identification is authentic.
Authorization is when a Trustor grants a Permission to a Digital Identity (a Trustee) to perform a privilege against a Target Resource
Digital Identity is Also Know as#
There are many terms used to represent essentially the same thing.- Resource Owner is used in OAuth 2.0
- Subject is used in Security Assertion Markup Language (SAML)
- User is often used
- Principal is often used
- Consumer of services may be used
Please do NOT use Account. An Account is a some place where a Digital Identity puts an Asset. (Just a thing with Ldapwiki folks.)
Digital Identity, well Identity, is a Facet Of Building Trust
Digital Identity Classification#
There two broad Digital Identity Classifications:- foundational identity - is a multi-purpose, allowing access to multiple services or Resources.
- functional identity - solely for a narrowly defined service or Resource. For example, a medical insurance card is used to access health care and a voter ID card serves the purpose of conducting a vote
People love to make up words and phrases to express themselves.
Digital Identitys may be classified by the type of Identity Provider (IDP):
Digital Identity might also be classified by the Relationship as:
classified by the Identity Management Framework of the Digital Identity:
Digital Identitys may be Classified as one of the following:
- Privileged Identity which may be further Classified
- NORMAL_ACCOUNT
Digital Identity and Context#
A given Digital Identity is typically related to a given Context.How a Digital Identity relates to a Digital Subject#
There should be some further understandings about how a Digital Identity relates to a Digital Subject:- A Digital Identity is a set of Attributes about a Digital Subject for a specific Context
- For any given Digital Subject there will typically exist multiple Digital Identities. For Example:
Digital Identity Data Stores#
Within an Organizational Entity (i.e think of a company there may be the following Data Stores: There is probably a Employee with a Digital Identity defined in each of these Data Stores. Each one of these Data Stores has Attribute Values or Identifiers which could be presented to a Verifier as a Claim so each of them has a seperate Digital Identity that is associated with the same Employee. The combination of these Digital Identities is the Digital Subject within the Organizational Entity. Some folks refer to this as an Identity Cube.More Information#
