If you’re ever concerned about the safety of using Google Docs as your go-to file storage service for work or personal documents, SafeGDocs might be just what you’re looking for if you’re a Firefox user.
Researchers from Gradient (Galician Research and Development Center in Advanced Telecommunications) have been working with Isis Innovation, a part of the University of Oxford in the UK, to develop a free add-on for Firefox that automatically encrypts (and decrypts) your Google Doc files, so you don’t have to worry about any ‘man-in-the-middle’ attacks or anyone accessing your account, at least not for your Docs sake.
The system works by first installing the Firefox Add-on. When we tested this, despite downloading it in the Firefox browser it downloaded the .xpi, which then had to be installed by double-clicking and selecting to use Firefox to open the file.
Once that process had been navigated, you simply need to authorize SafeGDocs access to your Google account and away you go. I should note that as part of the sign up process you must enter a valid personal Gmail address, Google Apps accounts are not supported.
