Hadoop, is one of the ongoing patterns in innovation which is utilized as a structure for the distributed storage, is an open-source appropriated figuring structure actualized in Java and comprises two modules that are MapReduce and Hadoop Distributed File System (HDFS). The MapReduce is intended for handling with enormous informational collections, it enables the clients to utilize a huge number of item machines in parallel adequately, by just characterizing guides and lessening capacities, the client can prepare huge amounts of information, HDFS is for putting away information on appropriated bunches of machines. Hadoop is normally utilized in a huge bunch or an open cloud administration, for example, Yahoo!, Facebook, Twitter, and Amazon. The versatility of Hadoop has been appeared by the notoriety of these applications, yet it is structured without security for putting away information. Using the Hadoop package, a proposed secure cloud computing system has been designed, so Hadoop would use the area to establish and enhance the security for saving and managing user data. Apache had also produced a software tool termed Hadoop to overcome this big data problem which often uses MapReduce architecture to process vast amounts of data. Hadoop has no strategy to assure the security and privacy of the files stored in Hadoop distributed file system (HDFS). As an encryption scheme of the files stored in HDFS, an asymmetric key cryptosystem is advocated. Thus before saving data in HDFS, the proposed hybrid based on RSA, and Rabin cipher would encrypt the data. The user of the cloud might upload files in two ways, non-safe or secure upload files.
