Advanced Access Controls and Deduplication for Privacy in Multimedia Cloud Computing

Abstract

This work provides a privacy-preserving multi-dimensional media sharing system, SMACD, for portable cloud computing scenarios within the context of widespread media sharing enabled by cloud computing and devices. Attribute-based encryption is used to jumble each media layer, ensuring media privacy and granular access control. To reduce the complexity of the get-to arrangement and adapt to the properties of multi-dimensional media, a multi-level get-to arrangement development with a secret-sharing plot is presented. For both intra-server and inter-server deduplication, decentralized key servers are offered. With cloud computing, databases and application software are moved to sizable data centers, where data and service management may not be entirely reliable. However, this special feature brings up a number of new, poorly understood security challenges. Due to the fact that both user data and applications are on provider premises, cloud computing raises data security problems as neither is entirely contained on the user's machine. Although clouds often have a single architecture, they can have numerous customers with various needs. The solution provided by all cloud providers is to use encryption methods to encrypt the data. To solve every issue, there's also a potential that the cloud service is unreliable
