The rapidly increased use of cloud computing in the many organization and IT industries provides new software with low cost. Cloud computing is beneficial in terms of low cost and accessibility of data. Cloud computing gives lot of benefits with low cost and of data accessibility through Internet. Ensuring the security of cloud computing is a major factor in the cloud computing environment, as users often store sensitive information with cloud storage providers, but these providers may be untrusted. So sharing data in secure manner while preserving data from an untrusted cloud is still a challenging issue. Our approach ensures the security and privacy of client sensitive information by storing data across single cloud, using AES, DES and RC2 algorithm.
