摘要：As one of the most sought-after technologies in the world today, cloud computing finds a prominent place among researchers, service providers, hardware and software engineers, and consumers alike. Among the key services provided by cloud computing, the most widely used is storage on the cloud. To ensure a high degree of reliability and an almost constant state of availability, cloud storage systems rely on replication of data. Replicating data is not without its costs. In an attempt to mitigate costs of storage, designers have banked on erasure coding practices in lieu of data replication. This has resulted in development of Cloud RAID systems. An ideal Cloud RAID system strikes an optimum balance between performance, storage, and reliability. In addition to this, data security is of paramount interest. In this paper, we introduce an entirely new technique of storing data in cloud networks by file type classification. Combining RAID types with this, our paper proposes a model that is robust and can withstand instances of hard disk failures. Further, we discuss a methodology that is embedded in our proposed framework that supports user authentication for data storage and retrieval. Our Secure User Authenticated Cloud RAID model shields user data from prying eyes and even from unauthorized attempts by the cloud service provider our Secure User Authenticated Cloud RAID architecture.
