System and method for providing data security in a hosted service system

Abstract:

Aspects of the present disclosure are directed to methods and systems for protecting sensitive data in a hosted service system. The system includes a host system having a database management system (DBMS) with a database and a query pre-parser. A processing application is configured to process a request from a tenant system and route the processed request as a query to the query pre-parser. The query pre-parser is configured to decrypt a sensitive data part of the query, generate a modified query including the decrypted sensitive data part, generate a database query using the modified query, and transmit the database query to the database.
