Researchers at Georgia Tech have built a prototype that encrypts files before they are sent to the cloud for storage. The so-called “CloudCapsule” system can be used with cloud storage services, such as Dropbox and Google Drive. The technology can also be used for desktops, laptops, and mobile devices, but the prototype is for just mobile devices — specifically, iOS. The prototype was created to combine process isolation present in mobile OSes with a seamless way of encrypting data you want to place into the cloud.”]
