Phone as Personal Identifier Provider

Full Title

Mobile Device Security: Phone as Personal Identifier Provider (PPIP)

Context

This is an extension of the Phone as Health Care Credential proposal to a broader audience of teams interested in high assurance Authentication.

Challenge

• User want to be in control of their own private information.
• Accessing some material, like user health information, should be well protected from leakage.
• The common approach to high assurance (IAL2 AAL2) access it to provide a trust and credentialed Identifier Provider that also performs user authentication.
• All past successful attempts to get users to create and maintain high assurance have been driving by enterprise solutions like technology companies or educational institutions.
• Consumers have been unwilling to accept the inconvenience of such high assurance solutions.

Solution

• Put the high assurance identifier in the consumer's hand, in their smart phone.
• They get to have as many identifiers as the want and can select which one to use with which provider.

Mobile Identifier Sources

• Interoperability with Mobile Driver's Licence
• Phone as Health Care Credential

Benefits

• The user feels like, and is, in control of their data sharing.

Next Steps

• This paper is designed to be a proposal to NIST for a SP 1800-xx document in their series of Cybersecure Infrastructure papers.
• It is an extension of the Kantara work to provide such a solution for US Healthcare.
• The following are the 3 parts of a sp 1800 document. We propose an outline of the first part below:

1. SP 1800-xxA: Executive Summary (PDF)
2. SP 1800-xxB: Approach, Architecture, and Security Characteristics (PDF)
3. SP 1800-xxC: How-To Guides (PDF)
