Cloud Storage
Currently, cloud storage is the best thing to happen to law enforcement since cell phones,” Roberts stated. Cloud storage is nothing more mysterious or cyber-techno than simply saving data to an off-site storage system maintained by a third party. Cloud storage is now extremely common. The Internet provides the connection between the computer (or handset) and the database.
The computer (cell phone) user sends copies of files over the Internet to the remote data server, which saves the information. To retrieve the data, or manipulate the files, simply gain access to the server through the Web.
With cloud storage you can access your data from any location that has Internet access…any location. You don’t need to carry storage or memory devices with you. You don’t even need to use the same computer (cell phone) to gain access to the information. You can allow other people to access the data file.
iCloud? That is Apple’s cloud storage system that allows you to back up and restore data on your Apply iOS devices like iPhone, iPad and iPod. They just need to be connected to the Internet. Text messages are on iCloud. So are apps purchased from iTunes. So are all the photos and video on the Camera Roll feature in iOS. iCloud keeps bookmarks and reading lists from the Internet.
The standard for Fourth Amendment search and seizure usually observes “in your personal possession.” Nothing in the cloud storage is in your full personal possession. It is all stored on someone else’s computer systems. Anything stored at Google or Facebook, the e-mails stored on Gmail or Hotmail, cell phone call logs on the wireless company’s storage servers, files stored at remote backup services like Carbonite are all, to a large degree, in someone else’s possession.
All that evidence is there. “All you have to do is ask,” Roberts noted. The perp might delete something from his phone, but he may forget to delete it from the cloud. The phone company does not keep text messages, but the cloud does. Send a search warrant to Apple or Google and asked for cloud contents and you may be surprised at the evidence you get back.
Formal training is necessary to become a cell phone forensic specialist. This training may be covered by grants, such as the Paul Coverdell Forensic Science Improvement Grant. Specialized hardware and/or software will be required. Software-based solutions include Paraben and Secure View. Hardware-based solutions are available from Cellebrite. Cellebrite is simple, portable and car-adaptable. The unit is a bit expensive, compared to the software-only solutions, including both an initial outlay and a yearly subscriber fee.
