Secure Document Sharing In Cloud By Providing Anonymity, Integrity And Privilege Depending On The Document Type

Abstract

In the world of the technologies, cloud computing has made a great positive impact. The services offered by cloud are being used by the customers on a daily basis. Though cloud is a buzzword, the security issue has been one of the topmost concerns. The user stores his data or document in the cloud and retrieves it when needed. At many times, this data is attacked and is accessed by people who don’t have access to it. This paper proposes a method, that ensures that a document is safely stored in the cloud and can only be accessed by the members who have access to it. The access rights are given to the members along with privilege constraints to access the document. The user also has the option to list out the data in the document that he wishes to share. The integrated cloud computing system comprises three key components: Cloud Service Provider (CSP), Sensitive Document Analyser, and User/Tenant Tracker. The CSP employs optimized job scheduling and a profit/loss calculator, adhering to a multi-tenancy framework for efficient resource utilization. The Sensitive Document Analyser categorizes user documents, employing encryption, OTP-based access, and a request handler for secure management. Meanwhile, the User/Tenant Tracker ensures system integrity through blockchain based verification and facilitates continuous improvement via feedback analysis. Together, these components form a robust and secure cloud infrastructure, providing advanced functionalities and safeguards for optimal user experience and data protection.
