Secured Multimedia Content in Cloud

Abstract

Cloud computing is getting more popular in the field of computer science because of its reliability instoring and assessing data remotely. Cloud computing is an emerging computing paradigm in which resources of the computing infrastructure are provided as services of the internet. Cloud computing allows consumers and businesses to use applications without installation and access their personal files at any computer with internet access. It allows user to store large amount of data in cloud storage and use as and when required, from any part of the world, via any terminal equipment. Since cloud computing is rest on internet, security issues like privacy, data security, confidentiality, and authentication is encountered. we propose a new design for large-scale multimedia content protection systems. Our design leverages cloud infrastructures to provide cost efficiency, rapid deployment, scalability, and elasticity to accommodate varying workloads. The proposed system can be used to protect different multimedia content types, including 2-D videos, 3-D videos and images. The system can be deployed on private and/or public clouds. Our system has two novel components: (i) method to create signatures of videos and images, and (ii) distributed matching engine for multimedia objects. The signature method creates robust and representative signatures of videos and images that capture the depth signals in these videos and it is computationally efficient to compute and compare as well as it requires small storage. We implemented the proposed system and deployed it on two clouds: Amazon cloud and our private cloud.
