Trusted access control value systems

An access control system, comprising:

• a first network node comprising:
• a first memory comprising:
• a first key;
• and
• a second key;
• and
• a tagging engine implemented by a first processor operably coupled to the first memory, configured to:
• obtain a data element;
• link the data element with an access control tag array comprising a plurality of access control tags, wherein:
• each access control tag is linked with an end user group;
• and
• each access control tag comprises a baseline access control tag value;
• generate a hash of the access control tag array;
• encrypt the hash of the access control tag array using the first key to generate an encrypted hash;
• apply the second key to the access control tag array, wherein the applying the second key obfuscates the access control tag array;
• and
• send the data element, the encrypted hash, and the obfuscated access control tag array to a target network node within an end user group;
• and
• a second network node comprising:
• a second memory comprising:
• the first key;
• and
• the second key;
• and
• a routing engine implemented by a second processor operably coupled to the second memory, configured to:
• receive the data element, the encrypted hash, and the obfuscated access control tag array;
• deobfuscate the obfuscated access control tag array using the first key to obtain the access control tag array;
• compute a hash of the access control tag array;
• decrypt the encrypted hash using the second key to obtain the hash of the access control tag array;
• compare the hash of the access control tag array to the computed access control tag array;
• forward the data element to the target network node in response to determining that the hash of the access control tag array to the computed access control tag array are the same;
• and
• block transmission of the data element to the target network node in response to determining that the hash of the access control tag array to the computed access control tag array are different.
