An efficient file system with Multi-Factor Authentication using Cryptography

Abstract: This project concerning of both privacy and security for web-based cloud services. As sensitive data could even be stored within the cloud for sharing purpose or convenient access; and eligible users also can access the cloud system for various applications and services. We are implementing two factor authentication for the data and implementing secret key generation for each file and each file has unique secret key so no one can access the data without secret key and moreover we are adding one more module called project manager he will be allow the particular user to access the file so if user holds both the things then only they can access the file. The main objective of the project is that two implementing additional security for the files so no one access the file without admin and project manager acceptance certificate..
