Anonymous Data Sharing Scheme in Public Cloud and Its Application in E-health Record

Abstract

Cloud computing is an on-demand availability of computer system resources, especially data storage and computing power, without direct active management by the user. The term is generally used to describe data centers available to many users over the Internet. Over the past few years, cloud computing has evolved quite quickly. Large amounts of data are uploaded and stored on remote public cloud servers, which users do not trust completely. In particular, most companies want to manage their data with the help of cloud servers. However, when outsourced data in the cloud is sensitive, the challenges of security and privacy are essential for the widespread deployment of cloud systems. This paper proposes a secure data sharing scheme to ensure the confidentiality of the data owner and the security of the outsourced cloud data. The proposed scheme provides a convenient advantage while addressing privacy and security challenges for data sharing. It demonstrates that the safety and efficiency analysis design scheme is feasible and effective. Finally, we discuss its application in the e-health (electronic health) record.
