If you could copy keys from a photograph what would it mean? How would security be compromised? Would this make people nervous?
As explained by this article in Wired (http://www.wired.com/2014/07/keyme-let-me-break-in/) anyone can easily copy keys by quickly taking photos with an iPhone app; then simply sending them to a company to recreate the keys.
This article gives us all a lot to think about. Copying keys this easily will start an important debate, I am sure we will be hearing more about this.
Will records on the management and control of keys assume a greater importance in the future?
