Abstract
A message processing server includes a message processor, a network interface, and a memory storing a token database of multi-layer tokens. Each token in the database includes a plurality of encrypted data layers. The message processor receives, via the network interface, at least one authorization message that identifies one of the tokens, derives a first decrypted data layer from the first encrypted data layer of the token, and extracts from the first decrypted data layer a second pointer to a secondary database that stores a predetermined data value. The message processor excises the predetermined data value from the secondary database.
