Abstract:
Embodiments of the present invention disclose a method, system, and computer program product for implementing user specific encryption in a database system. A computer receives a query statement including a user specific key and data, the data including data needing encryption and non-encrypted data. The computer encrypts the data needing encryption using the user specific key. The computer inserts both the encrypted data and the non-encrypted data into a table row in a database. The computer creates a hash of the user specific key, and stores the hash of the user specific key in the table row with the data.
