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. Claims-based identity abstracts the individual elements of identity and access control into two parts: a notion of claims, and the concept of an issuer or an authority.

They are what the subject is or is not. A claim is a statement that one subject, such as a person or organization, makes about itself or another subject. Claims are packaged into one or more tokens that are then issued by an issuer (provider), commonly known as a security token service (STS).

For Claims-Based Identity, the abstraction is narrower than the article's general subject matter: a positive case must preserve 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. Retaining only the name, a familiar example, or a downstream effect is insufficient. The specialist roles and tests remain anchored in computer science and information systems, which is why this identity is domain-specific rather than prime.

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.

Structural Signature¶

Sig role-phrases:

Defining carrier — Claims are packaged into one or more tokens that are then issued by an issuer (provider), commonly known as a security token service (STS).
Constitutive relation — 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.
Operating condition — Claims-based identity can greatly simplify the authentication process because the user doesn't have to sign in multiple times to multiple applications.
Recognition evidence — In addition, because certain facts (claims) are packaged with the token, the user does not have to tell each individual application those facts repeatedly, for instance by answering similar questions or completing similar forms.
Admissible variation — To facilitate this he requests a patron to present a driver's license, health insurance card or other identification (the token) that has been issued by a trusted third party (the security token service) such as the provincial or state vehicle license department, health department or insurance company.
Characteristic consequence — A claim is a statement that one subject, such as a person or organization, makes about itself or another subject.
Failure boundary — For example, the statement can be about a name, group, buying preference, ethnicity, privilege, association or capability.

What It Is Not¶

Not the whole field of computer science and information systems. The node requires the specific identity stated by 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.
Not an over-broad reading. However a closer examination reveals that this is not the case.
Not an over-broad reading. 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.
Not an over-broad reading. In traditional systems there is often confusion about the differences and similarities between what a user is/is not and what the user may/may not do.
Not automatically Identity (philosophy). Retrieval proximity does not establish equivalence; the two identities must be compared by carrier, operation, and failure boundary.

Scope of Application¶

Claims-Based Identity applies literally inside computer science and information systems wherever the source-defined carrier and relation can be established. Its documented habitats include:

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.
Benefits. In addition, because certain facts (claims) are packaged with the token, the user does not have to tell each individual application those facts repeatedly, for instance by answering similar questions or completing similar forms.

Outside computer science and information systems, the name should be retained only when these same operational conditions survive; otherwise the comparison belongs to the broader parent Pattern or should be marked as analogy.

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. The strongest recognition evidence in the frozen account is: In addition, because certain facts (claims) are packaged with the token, the user does not have to tell each individual application those facts repeatedly, for instance by answering similar questions or completing similar forms. A report should distinguish that evidence from a proxy, consequence, or common implementation. It should also state the qualification However a closer examination reveals that this is not the case. so that a reader can reproduce the classification rather than infer it from topical resemblance.

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 is a statement that one subject, such as a person or organization, makes about itself or another subject. This compression makes cases comparable while leaving parameters, conventions, exceptions, and evidential quality explicit. It is lossy by design: local history and implementation details may be omitted only when they do not alter the defining relation.

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. In addition, because certain facts (claims) are packaged with the token, the user does not have to tell each individual application those facts repeatedly, for instance by answering similar questions or completing similar forms.
Test variation. Change an implementation or setting while preserving to facilitate this he requests a patron to present a driver's license, health insurance card or other identification (the token) that has been issued by a trusted third party (the security token service) such as the provincial or state vehicle license department, health department or insurance company.
Run the collapse test. Remove the defining operation; if the label still seems equally apt, only a topic or correlate was retained.
Reduce cautiously. When the specialist conditions cannot be carried, route the residual comparison to Pattern.

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. An outside case receives the specialist name only when the same typed roles and rejection conditions can be filled literally; otherwise the comparison remains an analogy pending later graph densification.

Examples¶

Canonical¶

A claim is a statement that one subject, such as a person or organization, makes about itself or another subject. This case is canonical because it supplies a concrete carrier and lets the defining relation be checked rather than merely named.

Mapped back: carrier → the entities in the documented case; operation → 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; recognition evidence → In addition, because certain facts (claims) are packaged with the token, the user does not have to tell each individual application those facts repeatedly, for instance by answering similar questions or completing similar forms

Applied / In Practice¶

For example, the statement can be about a name, group, buying preference, ethnicity, privilege, association or capability. The applied case shows how the identity is used under a second setting or qualification while keeping the same operative relation.

Mapped back: changed setting → Identity and claims; invariant → 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; boundary → the case exits the class when however a closer examination reveals that this is not the case

Structural Tensions¶

T1 — Stable identity versus admissible variation. However a closer examination reveals that this is not the case. The tension matters because emphasizing only one side either dissolves the identity or overstates what the evidence and domain conventions warrant.

Diagnostic: Which changes preserve the defining relation, and which replace it?

T2 — Recognition versus proxy. 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. The tension matters because emphasizing only one side either dissolves the identity or overstates what the evidence and domain conventions warrant.

Diagnostic: Does the cited evidence establish the identity or only a correlated sign?

T3 — Definition versus implementation. In traditional systems there is often confusion about the differences and similarities between what a user is/is not and what the user may/may not do. The tension matters because emphasizing only one side either dissolves the identity or overstates what the evidence and domain conventions warrant.

Diagnostic: Is the observed implementation constitutive, optional, or merely common?

T4 — Scope versus overextension. 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. The tension matters because emphasizing only one side either dissolves the identity or overstates what the evidence and domain conventions warrant.

Diagnostic: Can every claimed application fill the same typed roles without metaphor?

T5 — Transfer versus domain accent. Claims are packaged into one or more tokens that are then issued by an issuer (provider), commonly known as a security token service (STS). The tension matters because emphasizing only one side either dissolves the identity or overstates what the evidence and domain conventions warrant.

Diagnostic: Does the receiving case instantiate Claims-Based Identity literally, co-instantiate Pattern, or only resemble it?

T6 — Autonomy versus reduction. 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. The tension matters because emphasizing only one side either dissolves the identity or overstates what the evidence and domain conventions warrant.

Diagnostic: What does Claims-Based Identity distinguish that the broader parent Pattern leaves together?

Structural–Framed Character¶

Claims-Based Identity is structural-leaning. Its structural side is the repeatable organization summarized by 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. Its framed side is the computer science and information systems vocabulary that fixes the carrier, evidence, exceptions, and admissible transformations.

Evaluative weight: the identity can be stated descriptively even when applications carry practical stakes. Human-practice dependence: the source-grounded carrier determines whether the relation exists independently or is constituted by a practice. Institutional origin: disciplinary conventions stabilize the name and test. Vocabulary portability: Claims-based identity can greatly simplify the authentication process because the user doesn't have to sign in multiple times to multiple applications. Import versus recognition: literal transfer requires the same mechanism; shape alone is analogy.

Its portable skeleton is Pattern. Its character: a recurring specialist identity whose thin organization can be abstracted, while its operational meaning remains domain-bound.

Structural Core vs. Domain Accent¶

What is skeletal. 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. The stable skeleton is the typed relation expressed in that definition and the entry's recognition and collapse tests. The source identifies these operative conditions: Claims are packaged into one or more tokens that are then issued by an issuer (provider), commonly known as a security token service (STS). 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. It further constrains recognition and variation through: Claims-based identity can greatly simplify the authentication process because the user doesn't have to sign in multiple times to multiple applications. In addition, because certain facts (claims) are packaged with the token, the user does not have to tell each individual application those facts repeatedly, for instance by answering similar questions or completing similar forms.

What is domain-bound. computer science and information systems supplies the operative entities, technical vocabulary, warrants, and exceptions that make Claims-Based Identity literal. Its documented scope includes the condition that Furthermore, claims-based identity enables applications to know certain things about the user, without having to interrogate the user to determine those facts. Another bounded application condition is that A single sign in creates the token which is then used to authenticate against multiple applications, or web sites. These are not decorative examples; they determine which carrier and evidence can fill the abstraction's roles.

Why no parent is asserted. Removing those specialist details does not currently yield one live catalog node that is a necessary genus for every instance. The entry is therefore approved as unparented rather than attached by topical resemblance. Its collapse evidence remains specific—To facilitate this he requests a patron to present a driver's license, health insurance card or other identification (the token) that has been issued by a trusted third party (the security token service) such as the provincial or state vehicle license department, health department or insurance company.—and future graph densification may discover a defensible relation only if it preserves that boundary.

Approved unparented node. No current live node supplies a defensible necessary genus or structural prerequisite for Claims-Based Identity. The reviewed identity 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. The accelerated suggestion was declined because topical or lexical similarity does not establish hierarchy; the node is admitted without a parent pending later graph densification.
Related reasoning operations. Evidence, representation, comparison, classification, transformation, or evaluation may participate in particular cases, but participation does not make any one of them a necessary parent of every instance.

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.

Not to Be Confused With¶

Pattern. The parent omits the specialist differentia. Tell: Can the case establish 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?
Identity (philosophy). Treat two occurrences, descriptions, states, or presentations as numerically the same entity only when a declared persistence and reidentification criterion licenses one referent across the difference. Tell: Which entry's carrier, operation, and failure condition are satisfied?
Authentication Failure. The breakdown of a system's identity-verification, in which a claim is accepted when it should not be — because the procedure checked too little, the wrong evidence, or evidence an impostor could produce — yielding a session that inherits the real actor's privileges and corrupts every control conditioned on 'who is this?'. Tell: Which entry's carrier, operation, and failure condition are satisfied?
Account sharing. Permit multiple people to authenticate as one nominal account by reusing its credentials or authenticators, collapsing individual identity, accountability, and revocation boundaries. Tell: Which entry's carrier, operation, and failure condition are satisfied?
A measurement, proxy, or consequence. Those may provide evidence without being the identity. Tell: Would Claims-Based Identity remain present if the detector or downstream effect changed?
A metaphorical analogue. A similar shape outside computer science and information systems lacks the specialist mechanism. Tell: Do the native roles transfer literally, or only the parent Pattern?
