Abstract: Among the various technologies of web Cloud Computing is one of the recent internet based computing technology. It provide us a virtual server and a huge size of database to store our data over the internet. Since it is easy to store and manage the data many organizations moving their confidential data into the cloud. But as it is an internet based technology we are concerning about the security related issues like hacking, stealing, misusing etc. These security related issues are the greatest obstacle in the popularity of cloud. Therefore we are going to use the combinations of three different algorithms- DSA, DES and Steganograohy. These algorithms help to reduce the problems of security on cloud.
