VALIDATING ENCRYPTED DATA FROM A MULTI-LAYER TOKEN

摘要

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.

1. A message processing server comprising:
a memory storing a token database of multi-layer tokens, each said multi-layer token including a plurality of encrypted data layers, a first of the encrypted data layers including a first data pointer, another of the encrypted data layers including the first encrypted data layer and identifying a reference data value; and a message processor coupled to the memory and configured to:
receive, from a communications device, an authentication request identifying a first data value;validate the authentication request from the first data value and the reference data value configured in one of the multi-layer tokens;receive, from the communications device, a first authorization message including a first cryptographic key;derive a first decrypted data layer by decrypting, with the first cryptographic key, the first encrypted data layer of the one multi-layer token and; and validate the first data pointer of the first decrypted data layer by receiving confirmation of the first data pointer pointing to a database entry comprising a second data value less than the reference data value.
