Secure File Sharing on Cloud: A Two-Factor Authentication Approach

Abstract

Cloud computing has emerged as an efficient tool for storing and sharing data among the various organizations, which provides massive storage and other benefits that make it easier to deal with real problems instead of hindered by problems of local storage and infrastructure maintenance. Although, cloud services benefit the individual and organization, it is still not considered a safe platform for sharing confidential information because the Cloud Service Provider has all the access to user’s data and data is transferred using one-tier authentication. We, in this paper, propose a scheme for file transferring files on cloud FTP server using two-factor authentication along with data encryption scheme to make the process of file sharing and communication on cloud more secure.
