Mobile Protoype Encrypts Data First, Ships To Cloud Later

'CloudCapsule' can be used with Dropbox and Google Drive. It locks down files prior to their storage in the cloud for accessing them without a proxy.

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, for locking down files prior to their storage in the cloud and for accessing them without a proxy. The technology can be used for desktops, laptops, and mobile devices, but the researchers initially have built a prototype for just mobile devices -- specifically, iOS.

"We thought its greatest utility would be in the mobile space," given the explosion in BYOD, says Paul Royal, associate director of the Georgia Tech Information Security Center (GTISC), where the prototype was created. "This lets us combine some of the reasonable process-isolation present in mobile OSes with a seamless and transparent way of encrypting data you want to place into the cloud."
