Structured encryption rules engine

A computing device, comprising:

• a memory;
• and
• a processor device coupled to the memory to:
• receive, by a rules engine that is running a rules-based application, a first transaction comprising a plurality of data fields, at least some of the data fields comprising data to be evaluated by a plurality of rules identified in the rules-based application, the first transaction comprising encrypted data in a first encrypted data field of the plurality of data fields that has been encrypted with a symmetric key in accordance with a structured encrypted algorithm;
• query, by the rules engine, the encrypted data using a first query token generated using the symmetric key to determine if the encrypted data includes a value used in a first condition identified in the plurality of rules;
• and
• take, by the rules engine, an action based at least in part on querying the encrypted data.

A non-transitory computer-readable storage medium that includes executable instructions to cause a processor device to:

• receive, by a rules engine that is running a rules-based application, a first transaction comprising a plurality of data fields, at least some of the data fields comprising data to be evaluated by a plurality of rules identified in the rules-based application, the first transaction comprising encrypted data in a first encrypted data field of the plurality of data fields that has been encrypted with a symmetric key in accordance with a structured encrypted algorithm;
• query, by the rules engine, the encrypted data using a first query token generated using the symmetric key to determine if the encrypted data includes a value used in a first condition identified in the plurality of rules;
• and
• take, by the rules engine, an action based at least in part on querying the encrypted data.
