- In this wiki all Identifiers apply only to digital entities which includes data base entries, like User Objects. Real-world names are considered to be merely Attributes.
- There is no meaningful distinction between a name and an Identifier.
- There is a very real confusion in the real-world as to the meaning of terms used in Identity Management.
- Lots of the energy spent by philosophers revolves around verbalism, or arguing about the meaning of words.
- The page on Knowledge discusses these problems in more detail. (tl;dr)
- The connection between digital entity identifiers and legal, or real-world identifiers is typically hazy.
- The concept of Levels of Assurance (LOA) was introduced as a measure of the likelihood that a digital identifier really was the same as a real-world identifier.
Clearly any large corporation has an immense advantage in every part of their relationship to a single human being. It is only the rule of law that prevents then from dictating every aspect of the interchange between each party.
This wiki seeks to have a common understanding. So terms are given more precise meaning in order that the statements made here can be more logically precise.
- Artificial Identifier
- Biometric Identifier
- Decentralized ID - aka the did is designed to support user creating and disabling of multiple Identifiers. This is the basis for Self-Sovereign Identity.
- Digital object identifier - a standardized way to create an unique identifier for an object, like a document.
- Distributed ID - this is designed to allow the distribute of User Information or Attributes across multiple sites.
- Electronic Data Interchange (EDI aka TDCC) standardized labels from ANSI X12
- Email Address - along with other Identifiers like phone number or IP address that often stands in for a legal name.
- Fake Identifier
- Global Business Identifiers aka GS1
- Legal Name a name assigned by some sort of sovereign (aka governmental) Registration Authority.
- Object Identifier an identifier that magically turns an object into an entity, which is defined as a named object.
- Medical Records Identifier
- MitID - used in Nordics mostly for banking https://www.nets.eu/dk-da/l%C3%B8sninger/nemid/mitid/Pages/NemID-is-becoming-MitID.aspx

- Personal Identifier
- Principal Identifier - in this wiki is limited to the Identifier of a computer process that was started by a Subject.
- Real Identifier aka Real-World Identifier, is one attribute of a Real-world Entity, at least for entities that have legal standing.
- Self-issued Identifier was first standardized in OpenID Connect but now has become the paradigm for Self-Sovereign Identity
- Session ID - assigned to a networking session to track Attributes of the session, for example the HTTPS session.
- Subject ID - is created by entities like an Identifier or Attribute Provider to use during authentication, for example in OpenID Connect.
- Tribal Identifier - typically a name created to identify one individual from another - still survives in primitive societies today.
- Trusted Identifier
- URI - Universal Resource Identifier - an IETF standard RFC
- URL - Universal Resource Locator - an IETF standard RFC
- URN - Universal Resource Name - an IETF standard RFC
- Vulnerable Identifier for homeless or other vulnerable populations. This can also apply to emergency medicine where the patient cannot be asked for a name prior to treatment.
- Web Site Identity
- X.509 Certificate is a format that holds a Distinguished name, which is the actual Identifier.
These should all be testable on at least one of:
- Identifier or Attribute Provider which can include an openID Provider run by the user as defined in OpenID Connect.
- Certificate Authority
- Registration Authority
- Trusted Resolver
- Universal Resolver
- The wiki page Trusted Identifier addresses the use of digital identifiers that carry some level of trust with them.
