Access grants

摘要

Provided are, among other things, systems, methods, apparatuses and techniques for storing access grants. In one implementation, a blinding factor and access information for accessing a restricted object are obtained; blinded access information is generated for the restricted object based on the access information and the blinding factor; and an anchor node is stored into a data store, with the anchor node being accessible by submission of an identifier, the anchor node at least one of containing or referring to sufficient information to obtain access to the blinding factor and the blinded access information, and the identifier for the anchor node being independent of the blinding factor.

主权项

1. A method of storing access grants, comprising;
obtaining a blinding factor and access information for accessing a restricted object; generating blinded access information for the restricted object based on the access information and the blinding factor; and storing an anchor node into a data store, wherein the anchor node is accessible by submission of an identifier, wherein the anchor node at least one of contains or refers to sufficient information to obtain access to the blinding factor and the blinded access information, wherein the identifier for the anchor node is independent of the blinding factor.
