Abstract
A system and method for controlling distribution and use of digital identity representations ('DIRs') increases security, usability, and oversight of DIR use. A DIR stored on a first device may be obtained by a second device for use in satisfying the security policy of a relying party. Release of the DIR to the second device requires permission from a device or entity that may be different from the device or entity attempting to access the relying party. Further, the use of the DIR to obtain an identity token may separately require permission of even a different person or entity and may be conditioned upon receiving satisfactory information relating to the intended use of the DIR (e.g., the name of the relying party, type of operation being attempted, etc.). By controlling the distribution and use of DIRs, security of the principal's identity and supervisory control over a principal's activities are enhanced.
