now a days cloud computing important paradigm for IT industry with reduced cost, pay as you use, scalability ,easy accessibility and improved flexibility. In online transactions clients data can be accessed by other party which makes privacy and security issues. To ensure the privacy of data over cloud it is good outsource the data is in encrypted format .while sharing personal data with third party ,it should be fine-grained access control, security, data confidentiality, authorization and authentication is crucial challenge. At the time of uploading of personal data in the cloud the owner of data losses the physical control also it can be hacked by hackers. Hence the providing the security is a big issue while sharing personal data in cloud environment. This can be solved by using cryptography mechanism at the time of data sharing that will increase the confidentiality of the data and Steganography hide the data in another file for storing the data securely in the third party storage service. By making use of several encryption techniques user can store the data on cloud without worrying about the security.
