In this paper, the authors proposed
an effective, efficient and flexible distributed
strategy with explicit dynamic data support to
ensure the accuracy of users’ data in the cloud.
In file distribution preparation, to provide
redundancies and assure data dependability
and reliability, erasure correction code is used.
This construction leads to extreme reduction in
the communication and storage overhead as
compared to the traditional replication-based
file distribution techniques. Data deduplication
is one of the essential data
compression techniques for eliminating or
exterminating duplicate copies of repeating
data, and is extensively used in cloud storage in
order to save bandwidth and reduce storage
space. To provide better data security, in this
paper the authors address the problem of
authorized data deduplication. Here several
new de-duplication constructions which
support authorized duplicate presented.
Security analysis demonstrates that the
proposed scheme is secure in terms of the
definitions specified in the proposed or security
model. As a proof, the prototype of proposed
authorized duplicate check scheme is
implemented and experiments are conducted
using the prototype. The proposed authorized
duplicate check strategy incurs minimal
overhead compared to normal operations.
