Abstract:
1. A system comprising: a first product code data provider that stores a set of data identified by a product code, wherein the first product code data provider transmits index information and permission information, wherein the index information associates the product code with the identity of the first product code data provider and wherein the permission information entitles accessing the index information to a second product code data provider and wherein the permission information further delegates an entitlement decision to the second product code data provider such that the second product code data provider is entitled to share the index information of the first product code data provider with a third product code data provider; and a central data repository that stores the index information and the permission information received from the first product code data provider; wherein, upon receiving a request from the third product code data provider, the central data repository provides the index information to the third product code data provider if and only if there exists a valid chain of said permission information that entitles accessing the index information to the third product code data provider.
