"They’re not even connected to anything, but their perpetual swinging action is what keeps the internet safe(r) from hackers and protects your online transactions from fraudsters." That sentence triggers me on so many levels. Down below in the article it says that cameras are sampling the motion. So, ultimately the setup is connected to something, and it is being actively used as a quality source of entropy for cryptography. Brilliant, actually, but this is not what "keeps the internet safe". Strong encryption is a source of trust, nothing more. Proper security needs to rely on a few things that we have to assume to be unbreakable. Only then we can build on top of that. Sadly, even unbreakable encryption, if used incorrectly, can bring the whole thing down. I really don´t like articles that sensationalize "neat details" and by that distort the bigger picture.
