Design and Implementation of a Framework to Preserve Privacy of Users Multimedia Data in Mobile Cloud

Abstract

Cloud computing is an emerging technology with in internet world which newlineprovides an opportunities to utilize software, applications and hardware resources newlinewithout any upfront investment to every individual. With the rapid change in newlinemobile applications and advancements in cloud computing, a new era is being newlineexpected in the form of mobile cloud computing. With the advancement of mobile newlinecloud computing, lack of data security and confidentiality of user is the only an newlineobstacle that must be overcome in wide adoption of mobile cloud computing. newlineImportant research is in progress in this emerging area in order to reduce the newlinesecurity concerns but still a lot work has to be done to produce a security. In newlinemobile cloud computing, data storage and data processing is done outside the newlinemobile devices. The mobile device user can use required applications or access newlinetheir data stored in cloud. The client can store his confidential data to the cloud. newlineThe client should be given assurance that the data will only be limited to newlineauthorized access. The cloud service provider assures the clients for proper newlinesecurity, confidentiality and privacy for data in their Service Level Agreement. newlineThere are proper privacy policies and procedures for data safety in cloud and newlineClients may be given full assurance by CSP regarding privacy and security but newlinethere may be risk of unauthorized access of client s sensitive data by cloud service newlineprovider or cloud attacker. Data may be transferred from one place to another newlineplace frequently so there may be security concerns of data while mobility. newlineTo secure the client s confidential data and to overcome various security newlinechallenges, we will analyses few possible solutions and propose blockchain based newlinesecure framework to preserve user s important data from client side. Blockchain is newlinea distributed database of records or a public ledger for all the data transactions newlinehence the user s data will be stored on distributed data storage servers. newline
