TOWARDS SECURE AUDIT SERVICES FOR OUTSOURCED DATA IN CLOUD

The rapid growth in the field of Cloud Computing introduces a myriad of security hazards to the information and data. Data outsourcing relieves the responsibility of local data storage and maintenance, but introduces security implications. A third party service provider, stores and maintains data, application or infrastructure of cloud user. Auditing methods and infrastructures in cloud play an important character in cloud security strategies. As data and applications deployed in the cloud are more delicate, the requirement for auditing systems to provide rapid analysis and quick responses becomes inevitable. In this work we provide a privacy-preserving data integrity protection mechanism by allowing public auditing for cloud storage with the assistance of the data owner's identity. This guarantees the auditing can be done by the third party without fetching the entire data from the cloud. A data protection scheme is also outlined, by providing a method to allow for data to be encrypted in the cloud without loss of accessibility or functionality for the authorized users.
