Analyzing and Proposing an Optimal Privacy Solution in Cloud Computing

Abstract

Now a days everything of our day to day life are highly influenced by the power of Internet and sharing of resources, however this open architecture of current information sharing model attracts major privacy concern and it became prime obstacle for information sharing. newlineDifferent kind of privacy attacks or threats has been experience by the development and expansion of cloud computing model, to address their severe issues like malicious nodes or clients and kinds of vulnerabilities various preserving techniques have been newlinepresented so far in the context of privacy. However legacy privacy threats and attacker can coexist in cloud and new advancement in cloud generally introduces new privacy threats and challenges. newline newlineTherefore, we can say that preserving privacy is a complex area which attracts researches also preserving privacy in cloud environment is big task and requires in-depth and multidimensional investigations obviously it is impractical to comprise all the dimensions of investigation into a single work. newline newlineResearchers projected privacy solutions which appears working well, but not found as optimal privacy solutions so, the cloud needs to give more secure services by using advance cryptography technique and advance proxy mechanism. newline newlineThis thesis work centres around analysing currently available privacy model and proposing an optimal privacy solution which promises for a balance between individual privacy and overall quality of the underlying system. newlineFirstly, we analyse few very famous privacy preservation schemes and present a comparative study on few important one. newlineThere after we proposed a privacy preserving upload mechanism which guarantees individual privacy while sharing of information along with overall quality of underlying system which depends on number of uploads. newlineWe have suggested an upload method which maintain individual client s medical privacy in a crowd sourced environment, the proposed solution also achieve quality of health monitoring system which further rely upon on the amount of uploads and if
