An Application to Secure Multimedia Data in Cloud Environment using Paillier Cryptography

The Cloud is an internet-based computing where shared resources, software and information are provided to the computer. Now a days it is one of the prominent technologies to provide wide variety of services. In this condition data can be categorized into sensitive and insensitive. Among these two types sensitive data requires security. The existing system does not provide any security concerns for storing sensitive data in the cloud environment. So, it is necessary to develop an application to provide better security to the sensitive data in the cloud environment. This paper presented one of the best cryptographic algorithm that is homomorphic encryption which is used to provide better security to the multimedia data in the cloud environment when streaming or after streaming is over. Through this algorithm data can be encrypt and upload into cloud environment as well as download and decrypt into original form. By using this application we can provide better security to the cloud environment when compare to existing one.
