Abstract : Social Research has shown that data security has always been animportant aspect of quality service for data service providers; but cloud computingposes new and challenging security threats. In fact, many of these threats areessentially old problems in a new setting, although they may be more acute.Throughout the talk, the speaker will investigate the in depth features of Microsoftand Amazon deemed to provide security with a particular focus onconfidentiality, integrity and availability of data. In all cases, we analyze the point ofview taken by the provider on whether the primary responsibility for confidentialityand integrity fall on the cloud user or on the cloud provider. In this research, we willintroduce a solution for user’s data integrity checking over the cloud computing byusing digital signature scheme and eliminating TPA. For implementing theapplication without using the TPA, we consider to follow the PDP model that issuitable to verify the data in User and Server side.
