Secure File Sharing for Secret Agencies with Hybrid Cryptographical and Fragmentation Systems

By using fragmentation, we are putting into practice a secure cloud storage system that uses the AES, Triple, DES, and Blowfish algorithms.Our systems are open to information sharing by the secret agencies.The modules Administrator, Data Owner, Data User, and Cloud Server are part of our project.The administrator is in charge of handling file access rights, data owner accounts, and data user accounts.The uploads and downloads can be observed by the administrator.The files will be uploaded into the system by the data owner.On the file, we are using double encryption.Seven pieces will be taken from the created cipher text.The Firebase cloud will get these pieces.By requesting that the seven fragments merge into a single fragment and that the file have two descriptions applied, the user can receive the files.As the file key, the plain text will download.After the data owner processes the user's request, the key will be sent to them via email.The file will download if the key is legitimate.during a text file download.The cloud can monitor data owners' and users' details, as well as track uploads and downloads.
