RESOLVING DATA DE-DUPLICATION IN CLOUD COMPUTING

Abstract - Cloud storage allows cloud users to overcome
space constraints and extend their storage without upgrading
their computers as one of the essential cloud computing
services. Data is often outsourced in an encrypted form to
ensure the security and privacy of cloud users. On the other
hand, encrypted data could waste a lot of cloud storage space
and make data sharing among approved users more difficult.
Encrypted data storage and management of deduplication
continue to be a problem. Traditional deduplication systems
are often based on particular application situations in which
data owners or cloud servers have complete control over
deduplication. They are unable to meet the diverse demands
of data owners based on the degree of data sensitivity. This
paper suggests a multiple Cloud Service Providers (CSPs)
model in which the data owner uploads the file, and the hash
MD5 algorithm is used to search for data replication during
cloud CSP storage. With different security criteria, it can
achieve data deduplication and access control. We've also
suggested a method known as Provable Ownership of the File
(POF). As a consequence, data storage management is more
safe, reliable, and efficient.
