Abstract:-In the domain of cloud computing in which data as aservice has demanding situations over shared data utilization and inter-accessfacilities, especially when we emphasize on data service activities and focusto think on insensitive and sensitive categories of information related to dataprovider concern. Data access policies that are being empowered overinsensitive data are being sufficiently scaled up whereas methodologies tointeract with sensitive information of data providers are to be enhanced to thepresent-day security requirements. So the privacy of user-specific sensitiveinformation is to be preserved by adopting effective and efficient encryptionmethodologies and not encouraging limitations of data utilization strategies.This brings great reliability and trustworthiness to personal and sensitiveinformation. Electronic health records or medical information or personalinsurance policy reports or preparatory personal employee information to getmaintained following high-level security strategies to bring reliability andusability in wider domains. To facilitate scalability, attribute-basedencryption is being adopted, facilitating authorized methodologies to beperformed over integrated security policies in multiple authority architecturalplatforms. With the focus on improvising security strategies by adoptingoptimal encryption methodologies, there might be an overhead and are barricadesto the search techniques of encrypted data formats.
