Zusammenfassung:A message processing server includes a message processor and a database of multi-layer tokens. Each token in the database includes a plurality of encrypted data layers. The first layer includes the second layer and a first pointer. The second layer includes a second pointer. The message processor is configured to receive a first authorization message including a first cryptographic key and a second value; decrypt the first layer of one of the tokens with the first key; validate the first pointer by receiving confirmation of the first pointer pointing to a database entry comprising the second value; receive a second authorization message including a second cryptographic key and a third value; decrypt the second layer of the token with the second key; and validate the second pointer by receiving confirmation of the second pointer pointing to a database entry comprising a maximum data value not less than the third value.
