Cloud Based Secure File Sharing Using Access Control

Abstract

In the current environment, data security is paramount, and any confidential files we must have with us everywhere we go raise the chance of losing such files. To prevent this inconvenient method of transporting private information, our suggested solution uses the cloud to store users' myriad of files of any size in encrypted form, encrypting them using the AES-256 version technique to ensure that your private data remains secret. The user no longer has to be concerned about security breaches when sharing his file with the intended recipient, since he may now provide permission to access his document to only the people he chooses, and it will only be accessible to him. With this approach, the saving and exchange of data is made possible. Our encryption algorithm uses the AES-256 version, in which all data is grouped into a string of bits and is subsequently converted into 128-bit blocks.
