By using cloud-based file synchronization services like Dropbox, we can free our digital lives from the confines of a computer, and access documents, photos, and music on several devices. However, this flexibility can leave some users feeling less than certain that their data is safe. With this in mind, iTwin has updated its eponymous file sharing hardware utility with a new feature named SecureBox. SecureBox is a free update available to all existing iTwin users which brings hardware protection to Dropbox accounts.
The basic iTwin SecureBox system works as follows: once the two included iTwin USB sticks have been activated, a SecureBox folder is placed within the user’s Dropbox folder, and files added to this location are automatically encrypted with a secure hardware key, plus an optional password.
In order to access the cloud-based files, one needs access to either one of the dual iTwin units (the company recommends one is kept in a safe location for backup), and relevant password. Without these requirements being met, the files will simply be unreadable to anybody who accesses your Dropbox account, and even the file names are obfuscated. The iTwin USB sticks can also be disabled remotely.
Dropbox already has good security measures in place, and there are many third-party apps available which harness the Dropbox framework to make your data more secure – which begs the question as to why anyone should bother with SecureBox in the first place? Well, while software encryption is ample for the average user, those who wish to use their Dropbox folder to handle confidential or important files may prefer an extra level of hardware security. The convenience and intuitiveness that comes with a dedicated hardware key is also an added benefit.
iTwin SecureBox is compatible with Microsoft Windows and Mac OS X, and the USB sticks are available in "lime green" and "gunmetal grey" versions, from US$99.
