This paper is about preserving the Cloud data whose idea is to cure
everyday problems with computing. Cloud computing is fundamentally
pooling the resources virtually and the resources like storage are
provided to the end-users through the web. Information preservation,
security, uniform quality, and interoperability are some issues related
to cloud computing. However, the most essential issue is Security and
how it is ensured by a cloud supplier. Security of data can be offered
by means of cryptography. This paper presents an improved composite data
protection mechanism to protect data on the cloud from illegitimate
access.
