"Attestation Officers bring urgently needed
authenticity to a world awash in inauthenticity."

Assessing Identity Quality

The process of establishing identify quality requires the Attestation Officer to review different documents representing Evidence of Identity (EOI) in addition to having the applicant recite An Oath of Identity recording through a Remote Online Notary video process to establish reliability of their identity.

Attestation Officers are trained in two processes to accomplish this. A description of the different processes follows:

  • NIST 800-63-3 – Digital Identity Guidelines

    The NIST 800-63-3 guidelines establish security and privacy controls for digital identity management for designated levels of assurance, including: identity proofing, authentication and use of authenticators, and identity federation. SP 800-63-3 establishes risk-based processes for the assessment of risks for identity management activities and selection of appropriate assurance levels and controls. Organizations have the flexibility to choose the appropriate assurance level to meet their specific needs.

    Attestation Officers will use these guidelines to establish a level of identity assurance in support of the customer’s (relying Party’s) needs.

    The NIST 800.63-3 guidelines do not include issuance of a digital certificate for the individual.

  • Osmio IDQA

    IDQA processes, developed by The Authenticity Institute, takes the concepts outlined by the NIST 800.63-3 guidelines to a more detailed level by including a digital certificate along with a scoring system from 0 to 72.

    The process of establishing identify quality and issuing a digital certificate requires a Certification Authority for the issuance and recording of the certificate and a process to determine the reliability of the identity.

    The Certification Authority we use is called Osmio, which is a duly constituted public authority located in Switzerland. It has been established as a non-commercial enterprise to prevent the potential of change of control to an organization with a lesser standard of integrity.

    Identity Quality Assurance (IDQA) represents a process to evaluate the quality of the identity that is being reviewed. This process results in a score that determines a measure of the reliability of the identity of that individual.

How Osmio IDQA™ adds value to your credential

While there exists an abundance of commercial identity verification services, only Osmio is prepared to assemble the output of those services along with other Evidence of Identity (EOI) to provide a permanent attestation of the level of confidence that you or your relying parties can have in a claim of identity.

Osmio and its agents, including Attestation Officers and Authorized Agencies, will provide a program of Identity Quality evaluation for all holders of your identity credentials.

With Osmio IDQA, the strength of a user’s identity claim — its Identity Quality — is evaluated using eight metrics, with each metric measured on a scale of zero to nine. All eight scores are then added together, giving an aggregate Identity Quality score of zero to seventy-two.

Relying parties (including your own organization) can set a minimum aggregate score, or minimums of any of the eight component scores, to grant or deny access to a resource.

The eight metric scores added together give an Identity Quality score of 0-72

How Osmio IDQA Scores Are Used

The eight scores are added together for an aggregate Identity Quality score of 0 to 72.

Whenever and wherever the credential is presented, the aggregate Identity Quality score and its eight component scores are presented, letting the relying party know the degree to which the identity claim can be relied upon.

Assignment of lower Osmio IDQA scores is done in an automated fashion, while the higher scores are assigned by a human Attestation Officer, as described previously in the Enrollment Component.

Some applications require more assurance of the validity of the identity claim than others. And some require different types of assurance. An online commercial real estate auction will want a high degree of assumption of liability (metric #7), while a social network for children will want to see that the user was enrolled in a face-to-face setting, establishing a high enrollment quality score (metric #2).

Watch

Osmio IDQA score inherited from Foundational Certificate

Most of the eight measures of identity quality of any puzzle kit are inherited directly from the Foundational Certificate, which ideally is a Digital Birth Certificate whose PEN (private key) signed the certificate signing request (CSR) of the utility or device certificate used in the everyday credential. However, everyday credentials can carry their own Osmio IDQA score. In fact, a credential’s Osmio IDQA score applies only to the actual certificate and the card, token, hard drive or other device that houses it.

The eight metrics of Identity Quality™ Each scored on a scale of 0-9

  • Degree of protection of personal assets

    Does the user have "skin in the game" or are your organization’s assets the only ones at risk? If the only reliable way to prevent credential sharing is to use credentials that protect the user's financial, reputational, and identity assets, then to what extent does the identity protect those personal assets? Ownership of the credential itself is considered in this score.

  • Quality of enrollment practices

    What type of enrollment procedure was used? Did it involve PII corroboration (“KBA”)? Was it face-to-face notarial or remote? How is provisioning performed? How is the process supervised and audited? How many eyes are watching? Each risk profile and highest protected digital asset value will call for a particular enrollment procedure.

  • Variety of means of assertion

    Does the credential support OpenID, i-Name, Shibboleth, CardSpace? Does it use SAML assertions? A well-used identity is a more reliable identity; the more places it is used the better.

  • Quality of authoritative attestation

    What source of authority attests to the validity of the assertion — that is, the claimed identity? Is the attesting party a certification authority? How reliable are their attestation practices? How is identity status reported: CRL, OCSP, or another method?

  • Attestations from others

    To what extent does the “complex relational web” of self-sovereign methods support the subject’s claim of identity, and to what extent do colleagues, employers, and sources of other relationships corroborate the subject's claim of identity? The more acquaintances who are willing to back up the subject’s claim of identity, and the higher the scores of those who do so, the higher this score will be.

  • Quality of the credential

    What are the characteristics of the credential and its carrier? Is one key pair used for everything, or are different key pairs or simple serial numbers used for different applications? The carrier of the credential is equally important. Some risk-profile/asset-value situations call for two-, three-, or four-factor hardware tokens or a one-time password, while a soft credential in the client computer or even a record in a directory will suffice for others.

  • Quality of assumption of liability

    If fraud is committed with the use of the credential, who carries the liability? Is that commitment bonded? What are the terms of the bond? What is the source of funds for fulfillment of the bond? Are there caveats or is the commitment absolute, regardless of the circumstances that made the credential available to the perpetrator? To protect assets and processes of the highest value, where a compromised identity would have the most serious consequences, there should be both civil and criminal liability involved in the issuance and ongoing use of the credential. Equally important is protection against fraudulent repudiation. Non-repudiation is the most difficult goal for a trust system to achieve, but it is necessary for the system to be useful to relying parties where significant transactions are involved.

  • Reputation of the credential

    How long has the credential been used without revocation or reported compromise? How many transactions and authentication events has it been used for in total? The longer a credential has been used without incident, the more reliable it tends to be. Note that the reputation of the credential is not the same thing as the reputation of the person. For example, if someone with a very good reputation has a habit of lending his or her credential to family members and colleagues — resulting in documented confusion over who is responsible for what — then the reputation of the credential is diminished.
