A SYSTEM AND METHOD OF DYNAMIC ISSUANCE OF PRIVACY PRESERVING CREDENTIALS

摘要

Method and System for enhanced privacy in privacy-preserving identity solutions. The technology provides for a redirect of a request to generate a proof of an attribute from a service provider to a separator. The separator removes source identification from the attribute-proof request and redirects the attribute-proof request, free of original source identification, to a credential issuer which issues the credential. A security device of the user generates a presentation token from the privacy-preserving credential and presents the presentation token to the service provider as proof of the attribute. Other systems and methods are disclosed.

1. A method for authenticating a user, operating a web application, for example, a web browser, on a host computer, to a web-based service provider service, comprising:
redirecting a request to generate a credential from a service provider to an identity provider via a separator, by:
transmitting a first request for a credential to the separator;operating the separator to transmit a second request for the credential to the identity provider without identifying the service provider as originator; operating the identity provider and a security device associated with the user:
to engage in a privacy-preserving credential creation exchange in cooperation with the identity provider; operating the security device to generate a presentation token from the privacy-preserving credential; and
to present the presentation token to the service provider as proof of the attribute.
