The aim of the project is to secure the saved data stored in the untrusted service provider i.e. public cloud. Opening an account on Rackspace public cloud and storing the sensitive data. Files such as user's pictures, videos, Pdf files, Microsoft word file, Microsoft Excel files will be saved on the cloud account. To secure the data the user will use different encryption methods such as AES, DES, RSA Algorithms on these files and then using fragmentation method the encrypted file will be uploaded to the cloud account. Using SQL (Structure Query Language) the saved data can be retrieved from the account. Later the user can perform decryption method to bring the data to the original format. By combining the encryption algorithms, decryption algorithms, and fragmentation technique the user will provide a high security for the data stored in the cloud.
