"One Laptop per Child" Security System
It’s called “Bitfrost,” and it’s interesting:
We have set out to create a system that is both drastically more secure and provides drastically more usable security than any mainstream system currently on the market. One result of the dedication to usability is that there is only one protection provided by the Bitfrost platform that requires user response, and even then, it’s a simple ‘yes or no’ question understandable even by young children. The remainder of the security is provided behind the scenes. But pushing the envelope on both security and usability is a tall order, and it’s important to note that we have neither tried to create, nor do we believe we have created, a “perfectly secure” system. Notions of perfect security in the real world are foolish, and we distance ourselves up front from any such claims.
What they propose to do is radical, and different—just like the whole One Laptop Per Child program. Definitely worth paying attention to, and supporting if possible.
