While bringing undeniable benefits to both data owners and end usersaccessing the outsourced data, moving to the cloud raises a number of issues, ranging from choosing the mostsuitable cloud provider for outsourcing to effectively protecting data and computation results. In this paper, wediscuss the main issues related to data protection arising when data and/or computations over them are movedto the cloud. We also illustrate possible solutions and approaches for addressing such issues. 收起
