Abstract:

Cloud Storage offer users an easy way of storing and sharing data, but due to privacy concerns of users, data encryption was introduced. Among
available forms of data encryption, Attribute based encryption (ABE) has been largely adopted because it provides a pliable secured approach for users to save and distribute data in cloud by enforcing an accesscontrol policy over data, hence only users who satisfy the access-control policy will be able to decrypt and access the encrypted data. However, traditional ABE cloud storages do not support secured data deduplication (a process of eliminating copies of identical data) which is vital in data management to ensure judicious utilization of storage space and network band-width. This work proposes a scheme to integrate secured data deduplication on an Attributebased Encryption Cloud Storage by resorting to a dual cloud setting, where one (private) cloud executes data deduplication, while the other (public) cloud provides storage service. Python programming language, jQuery, JavaScript, CSS, HTML. Heroku server was used to test the system during development. Experimental results show that secure deduplication of encrypted data can be achieve on an Attributebased cloud storage through a dual cloud approach where the private cloud is trusted.
