Avoid duplication in cloud system with improved security and reliability

Data duplication is technique has been widely used in a cloud to reduce storage space and upload bandwidth. This technique is also used for eliminating duplicate copies of data. However, in cloud only one copy of each file is stored even if each file is owned by a huge number of users. The duplication system improves storage utilization but it reducing reliability, according to user. Furthermore, in above challenges the Data duplication is a technique has been widely used in cloud servers that are data storage makes first attempt for formalize notation of distributed reliable duplication system. We propose, new distributed duplication systems are improves security and reliability. In which the multiple cloud servers are distributed in data chunks. In Distributed storage system, the deterministic secret sharing scheme is achieved security requirements of data confidentiality and tag consistency, instead of using tag conversion and message authentication code as in duplication system. Security observations makes clear by reasoning that our de-duplication systems are get in terms of the clear outlines detailed in the made an offer safety good example. As a fact in support of idea of a quality common to a group, we give effect to the made an offer systems and put examples on view that the caused overhead is very limited in true to likeness conditions.
