Implementation Of Two Factor Access Control Mechanism Using Cloud

Computer Engineering

In the present scenario cloud computing had become one of the emerging trends. Cloud computing often referred to as describes the act of storing, managing and processing data online. Security and privacy is one of the indispensable concerns in cloud as sensitive data are stored in the cloud for sharing purpose or convenient access. This paper deals with the fine-grained two-factor authentication (2FA) access control system for web-based cloud computing services. In our proposed 2FA access control system, it is mandatory for the user to possess both user secret key, which will be generated by the admin when he authenticates the user’s file request and an OTP which will be generated on successful login. This mechanism can intensify the security of the system, as a user cannot access the system if he does not hold both, especially in those scenarios where many users share the same computer for web-based cloud services.
