Core Idea¶

Claims-Based Identity is treated here as the recurring computer science and information systems identity summarized by this source-grounded definition: Claims-based identity is a common way for applications to acquire the identity information they need about users inside their organization, in other organizations, and on the Internet. Claims-based identity is a common way for applications to acquire the identity information they need about users inside their organization, in other organizations, and on the Internet. It also provides a consistent approach for applications running on-premises or in the cloud.

How would you explain it like I'm…

The Trusted Note About You

Imagine going to a fair. A trusted helper at the front checks who you are and gives you a wristband that says things like 'this kid is 7' and 'this kid paid.' Then each ride just reads your wristband instead of asking you all over again. Claims-based identity works like that for computer programs.

Digital Name-Tag Notes

Claims-based identity is a way for computer programs to learn what they need to know about the people using them. A 'claim' is a statement, like 'this person's name is Sam' or 'this person works here.' A trusted service, called an issuer, packs these claims into a digital package called a token. The program trusts the issuer, so it can read the claims instead of checking everything by itself. This works for people in the same company, in other companies, or anywhere on the internet.

Issuer-Backed Identity Claims

Claims-based identity is a common approach for applications to get the identity information they need about users, whether those users are in the same organization, in other organizations, or on the internet. It breaks identity and access control into two ideas: claims and an issuer. A claim is a statement that one subject, such as a person or organization, makes about itself or another subject, for example a name, role, or group membership. Claims are bundled into one or more tokens, which are issued by a trusted authority often called a security token service (STS). The application then relies on the issuer's tokens rather than managing all identity data itself. It works the same way whether the application runs on the company's own servers or in the cloud.

Claims-based identity is a widely used way for applications to obtain the identity information they need about users inside their own organization, in other organizations, and on the internet, with a consistent approach whether the application runs on-premises or in the cloud. It abstracts identity and access control into two elements: claims and an issuer or authority. A claim is a statement that one subject, such as a person or an organization, makes about itself or about another subject, describing what the subject is or is not, for example a name, email, or role. Claims are packaged into one or more tokens, which are issued by an issuer (identity provider), commonly a security token service (STS). The relying application trusts the issuer and makes its decisions from the claims in the token instead of directly collecting and verifying all identity attributes itself. What defines the pattern is this acquisition of identity information as issuer-vouched claims in tokens, not identity management in general.

Scope of Application¶

Benefits. Furthermore, claims-based identity enables applications to know certain things about the user, without having to interrogate the user to determine those facts.
Benefits. A single sign in creates the token which is then used to authenticate against multiple applications, or web sites.
Identity and claims. It is up to the application receiving the incoming claim to map the is/is not claims to the may/may not rules of the application.
Benefits. Claims-based identity has the potential to simplify authentication logic for individual software applications, because those applications don't have to provide mechanisms for account creation, password creation, reset, and so on.
Benefits. Claims-based identity can greatly simplify the authentication process because the user doesn't have to sign in multiple times to multiple applications.

Clarity¶

A clear use of Claims-Based Identity names the carrier, the operative relation, and the conditions under which the source treats the identity as present. The minimal definition is Claims-based identity is a common way for applications to acquire the identity information they need about users inside their organization, in other organizations, and on the Internet.

Manages Complexity¶

Claims-Based Identity compresses multiple computer science and information systems details into a stable diagnostic relation. The source shows both the central mechanism—once the distinction between what the user is/is not and what the user may/may not do is clarified, it is possible that the authentication of what the user is/is not (the claims) can be handled by a third party.—and the practical consequence—a claim.

Abstract Reasoning¶

Type the carrier. Identify the computer science and information systems entities to which the claim applies.
State the relation. Use the source-grounded identity: Claims-based identity is a common way for applications to acquire the identity information they need about users inside their organization, in other organizations, and on the Internet.
Check operation and conditions. Claims-based identity can greatly simplify the authentication process because the user doesn't have to sign in multiple times to multiple applications.
Demand recognition evidence.

Knowledge Transfer¶

Within the home domain. Knowledge about Claims-Based Identity transfers literally when a new case preserves the same carrier type, relation, and recognition test. Furthermore, claims-based identity enables applications to know certain things about the user, without having to interrogate the user to determine those facts. A single sign in creates the token which is then used to authenticate against multiple applications, or web sites. Beyond the home domain. No canonical parent is asserted for Claims-Based Identity.

Neighborhood in Abstraction Space¶

Claims-Based Identity sits in a sparse region of the domain-specific corpus (70^th percentile for distinctiveness): few abstractions share its structure, so a faithful description tends to retrieve it precisely.
