Abstract: Cloud computing is a recent trend of technology that aims to provide unlimited, on-demand, elastic computing and data storage resources. In this context, cloud services decrease the need for local data storage and the infrastructure costs. However, hosting confidential data at a cloud storage service requires the transfer of control of the data to a semi-trusted external provider. Therefore, data confidentiality is the top concern from the cloud issues list. Recently, three main approaches have been introduced to ensure data confidentiality in cloud services: data encryption; combination of encryption and fragmentation; and fragmentation. In this paper, we present i-OBJECT, a new approach to preserve data confidentiality in cloud services. The proposed mechanism uses information decomposition to split data into unrecognizable parts and store them in different cloud service providers. Besides, i-OBJECT is a flexible mechanism since it can be used alone or together with other previously approaches in order to increase the data confidentiality level. Thus, a user may trade performance or data utility for a potential increase in the degree of data confidentiality. Experimental results show the potential efficiency of the proposed approach. (More)
