ABSTRACT :

 Cloud Computing is evolving from a mere "storage" technology to a new vehicle for Business Information Systems (BIS) to manage, organize and provide added-value strategies to current business models. Cloud platform server cluster is running in the network environment and it may contain multiple users' / tenants data and the data may be scattered in different virtual data centers. In a multi-user shared cloud computing platform users are only logically isolated, but data of different users may be stored in same physical equipment. These equipments can be rapidly provisioned, implemented, scaled up or down and decommissioned. Current cloud providers do not provide the control or at least the knowledge over the provided resources to their customers. When the SLA between the customer and the cloud provider ends, today in no way it is assured that the particular customers' data is completely destroyed or destructed from the cloud provider's storage. In this paper we explore the key implementation patterns of data storage and methods to identify individual customer data and securely delete / destruct it.

Keywords: Multi-tenant Database, Cloud Computing, Data Lifecycle, Encryption, Cryptography, Meta-data
