TOKEN-BASED SYSTEM FOR EXCISING DATA FROM DATABASES

摘要

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.

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 network interface; and a message processor coupled to the memory and the network interface and configured to:
receive, via the network interface, at least one authorization message identifying one of the multi-layer tokens;derive a first decrypted data layer from a first of the encrypted data layers of the one multi-layer token;extract from the first decrypted data layer a second pointer to a secondary database storing a predetermined data value; andexcise the predetermined data value from the secondary database.
