Abstract: Cloud services provide flawless service to the client by increasing the
geographic availability of the data. Increasing availability of data induces
high amount of redundancy and large amount of space required to store that
data. Data compression techniques can reduce the amount of space required for
that data to be store at various sites. Data compression will ensure that there
is no loss of availability and consistency at any site. As there is huge demand
for cloud services and storage due to this the amount of investment also
increases. By using data compression we can reduce the amount of investment
required and this will also decrease the amount of physical space and data
centers required to store data. Various security protocols can be incorporated
to secure these compressed files at various sites. We provide a reliable
technique to store deduplicates and its management in a secure manner to
accomplish high consistency as well as availability.
