Got some information that's too secret to be mistakenly accessed? The number of data protection software offered are one too many today but that's just on a personal level, what if the information you hold is critical either for defense or just a few scanned secret letters you wrote to a girl in school? You would definitely not want your wife to read any of them. Instead of using unreliable mathematical models to protect data, this new chip by Siemens uses photos to generate unique codes by an optical array, which in turn generate random codes. These codes are sent to the receiver via optical fiber cables that then verify the codes and generate a fool proof Key. The light lock is so secure, that unless this key is not verified and put in place the message is not transferred to the other end. The key also is destroyed once the data is used.

The Siemens light lock is designed in a way that any attempt to tap into the system and listen in on the key will cause it to register the malfunction and change or kill photons to produce another unique set of codes and therefore a new key. It's kind of like a lock which will change the grooves in its internal mechanism when a false key is inserted.
