Secure Login, Data Sharing and Recovery on Cloud

In our proposed project, the users can share their files (like PDF, Audio, Video, etc. ) over the internet through cloud to other users. The user will have two options while sharing the file Public and Private. In Public, user can publically share the file with TPU and they can view the same file multiple times, while in Private, the TPU has to request for having the access to the file only once, and after the one-time access the shared file will get deleted automatically. Also, before the file is shared, it will be safely stored in the users cloud space. Thus, the secondary memory of the users device will not be utilized for saving of the file data. The particular cloud will be secured by using two-layer encryption approach to secure data sharing in cloud computing. Encryption technique which we will be using is Improved AES algorithm. Seed block recovery algorithm is used to recovery any lost/deleted data from the cloud. It is the most efficient algorithm available till date with the efficiency of 95 %. Seed Block uses logical operations to recover the lost data.
