Abstract:
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 a first data pointer. A primary layer includes the first layer and identifies a reference data value. The message processor receives from a communications device an authentication request identifying a first data value, validates the authentication request from the first data value and the reference data value configured in one of the multi-layer tokens, receives a first authorization message including a first cryptographic key, derives a first decrypted data layer from the first cryptographic key and the first encrypted data layer of the one multi-layer token, and validates the first data pointer by receiving confirmation of the first data pointer pointing to a database entry comprising a second data value less than the reference data value.
