IBM’s White Paper: Guard your organizations data with intelligent IBM encryption. IBM: Encryption should always be protected through the use of encryption or how it is stored. Encryption is a data island from which you cannot escape without additional custom code on behalf of the vendor. The data should flow naturally from the premises to the cloud and back, and the keys required to decrypt it should not need to be changed. The solution to data islands is standard file formats, and encrypted data should be no different.”]
