Trusted access control value systems

Abstract:

A system that includes a tagging engine and a routing engine. The tagging engine is configured to link a data element with an access control tag array that links access control tags with end user groups. The tagging engine is configured to encrypt a hash of the access control tag array using a first key and to apply a second key to the access control tag array to obfuscate the access control tag array. The tagging engine is configured to send the data element, the encrypted hash, and the obfuscated access control tag array to a target network node. The routing engine is configured to compute a hash of the access control tag array and to forward the data element to the target network node in response to determining that the received hash of the access control tag array to the computed access control tag array are the same.
