Brad Tumy gave a presentation on identity assurance at the 2013 Open Stack Identity Summit in France. The presentation covered topics such as levels of identity assurance, common identity assurance frameworks, implementation requirements, and a typical identity assurance architecture model. It discussed using identity assurance to determine the level of certainty that an electronic credential represents the actual entity it claims to.

Identity Assurance

6. Identity Assurance
“… the ability for a party to determine, with some level of certainty, that an
electronic credential representing an entity - whether a human or a
machine, with which it interacts to effect a transaction, can be trusted to actually belong to the entity.”
Levels of
Assurance
Confidence Level
Examples
1
Little or no confidence
Google (IDP), Facebook (IDP)
2
Some confidence
Corporate username and
password
3
High confidence
2FA (Smart card, OTP, etc)
4
Very High Confidence
Smart Card (but requires inperson identity proofing)

Identity Assurance
Frameworks

8. A few major Identity
Assurance Frameworks
Swedish eLegitimation
Pan-Canadian
STORK
InCommon
Kantara
IDAP
NSTIC /
FICAM
Australian Access
Federation (AAF)
National Electronic
Authentication Framework

9. Identity Assurance
Framework Principles
Identity Assurance Principle
Control afforded to a user
1. User Control
Identity assurance activities can only take place by
user consent
2. Transparency
Identity assurance can only take place in ways user
understands and when fully informed
3. Multiplicity
User can choose as many different identifiers or
identity providers as desired
4. Data Minimization
Request or transaction uses minimum identity data as
necessary
5. Data Quality
User chooses when to update records.
6. Service-User Access and Portability
User has to be provided copies of user’s data on
request; user can move data whenever they choose
7. Governance / Certification
All participants in Identity Assurance System must be
accredited
8. Problem Resolution
Independent Arbitration
9. Exceptional Circumstances
Any exceptions have to be approved by Governing
body and subject to independent scrutiny
@brad_tumy

10. Principles / Product
Mapping
Identity Assurance Principle
1. User Control
User Consent Screen in SAML Transaction
2. Transparency
User Consent Screen in SAML Transaction
should display attributes being shared and
how it is being shared.
3. Multiplicity
Identity Proxy / IDP Finder
4. Data Minimization
@brad_tumy
OpenAM Configuration
SAML Response should only send required
attributes
