In cloud computing, data owners upload their data to the public cloud server. The server may not be secured so it can be attacked easily and data can be taken from the server. For many security reasons this data has to be encrypted before uploading it to the cloud server. In the proposed system data owners encrypt their data before uploading by creating a key for security, and the users search their required data in the cloud server. If the data is found, it is received by the user in the encrypted form. To decrypt the data the user has to be authenticated by the data owner.
