Storage Efficient Data Security Model for Distributed Cloud Storage

摘要

Digital Data or information is multiplying in a tremendous volume nowadays. Due to storage capacity restriction in local devices we use in our daily life, this concern was getting a great importance for on demand new innovation to eliminate the restriction. The development of Storage as a Service (STaaS), a cloud-based distributed storage framework fulfilled all the necessities of consumers. It can handle a huge amount of data by its scalable computing power and resources. Because of the expanding measure of data, a few important security issues arise for information security, privacy, confidentiality, trustworthiness and authentication. These issues the significant barrier in the adoption of cloud computing as STaaS. As indicated by a survey by EMC, practically 75% of current digital data is the copied duplicates that hold up a lot of extra storage space in the cloud. So, efficient uses of storage are also important. In this paper, we proposed an approach that is storage efficient and eliminates the issue of data security for distributed cloud-based storage (STaaS) with the use of data compression and cryptography procedures. The transferred data to the cloud will be compacted and encoded with compression and Encryption algorithm and afterwards, the output data will be chunked and stored onto the distributed storage which will make the transferred data hard to get any access even for the cloud service providers without data owner's permission. If data compression and encryption are executed simultaneously, at that point it requires less processing time and more speed.
