[FDE] Invention vs. Innovation vs, Process Improvement

[Ali, Saqib]

Hello All,

I am looking for some examples of the following in the security field:
1) Invention;
2) Innovation; and
3) Process Improvement.

Can you please provide examples Security related technologies that
fall into each of these categories.

Note: That I am using the strict definition of Innovation, which is:
"Innovation occurs when someone uses an invention - or uses existing
tools in a new way - to change how the world works, how people
organize themselves, and how they conduct their lives. Innovation is
distinct from improvement in that it causes society to reorganize.
Innovation is taking an invention and finding new uses for it."
Wikipedia.

Please make sure when you provide examples of innovation it conforms
to the above definition.
