Comparison for Confidential Cryptography in Multimedia Cloud Environment

Abstract

The working pattern and lifestyle of people has been changed due to wide adoption of cloud computing in daily life. Cloud is a perfect match for the low configured mobile devices. However, security of crucial data at cloud is always an issue of concern for its widespread applications. In this paper we have discussed the existing cloud security concerns for such crucial media data, along with that we have also reviewed our earlier proposed integrated algorithm for performing encryption and decryption while retrieving and storing multimedia data (images, audio and video files) to/from the cloud. As security of sensitive private media data of a client at cloud server is a big question and multimedia data handling always requires special attention. This proposed integrated security algorithm works in contribution towards this. In this paper we have made a detailed analysis of this algorithm and also compared it with some other proposed hybrid algorithms for a secure multimedia cloud computing environment.
