❶ Set up a secure area at the server end and an encrypted disk area at the client end.
❷ Create a secure tunnel between the server end and the client.
❸ At this time, the file on the server end can only be saved to the client’s secure area via the secure tunnel.
❹ User will be unable to move files which are located inside the encrypted disk area to non-secure areas (other disks or drives not within the encrypted disk area, servers at non-secure areas, etc.) via email, applications, or programs.
