CNET has learned that Google may be implementing measures to keep the government (or anyone else) out of your Google Drive-stored data. Should this be true, folks concerned about their privacy -- everyone, we would hope -- might rest easier in a post-PRISM world. According to one of CNET's anonymous sources, this isn't some flight of fancy, either: A small percentage of Drive files are already protected. Of course, even such digital protection is not guaranteed to keep your files private, but it would force those who would like a peek to obtain your login credentials first. Not that Uncle Sam would ever do such a thing without legal permission, right?
