Ensuring Security Services for Data Storing and Data Sharing in Cloud Computing

Abstract: Cloud computing make it possible to store large amounts of data. To monitoring User an entity whose data to be stores in the cloud and relies on the cloud for data storage and computation, server is an entity which manages by cloud service provider to provide data storage service and has significant storage space and computation resources and third party is an optional TPA who has expertise and capabilities that users may not have is trusted to assess and expose risk of cloud storage services on behalf of the users upon request. Our proposed work cloud computing architecture for analysis is cloud data storage a user stores his data through a CSP into set of cloud servers which are running in a simultaneous cooperated and distributed. We are proving an option to the user while uploading that is this file is public or group or private for data sharing. Considering the cloud data are dynamic in nature, the proposed design further supports secure and efficient dynamic operations on outsourced data, including block modification, deletion, and append
