Abstract

In an example, a subject using a user mobile-identification-credential device (UMD) requests vetting by a vetting system, which receives verified subject information associated with a level-n mobile identification credential (MIC-n) that UMD received from a level-n authorizing party system (APS-n). MIC-n is linked to lower level MIC-0 to MIC-(n−1). The vetting system, as level-n relying party system (RPS-n), uses the verified subject information associated with the linked MIC-0 to MIC-n to verify or not verify the identity of the subject, develops an identity profile of the subject, and determines a vetting result of the subject by calculating a composite trust score based on MIC trust values for the multiple levels of MIC. MIC-i (i=1 to n) is linked to MIC-(i−1) which UMD received from APS-(i−1), and APS-i is RPS-(i−1) which verified the identity of the subject using verified subject information associated with MIC-(i−1), such that MIC-0 to MIC-n are linked.
