System and method for perpetual rekeying of various data columns with a frequency and encryption strength based on the sensitivity of the data columns

Abstract:

A data management system stores data related to a plurality of users. The data management system initially stores the data in an encrypted format. The data management system automatically periodically re-encrypts the data in accordance with a re-encryption policy. The re-encryption policy includes re-encryption periodicity data defining a periodicity for automatically re-encrypting the data.
