However, the statement that we are discussing about assumes that such
system does not take in any data at all. In that sense, I could only
imagine "hello world". And how could "hello world" not be 100% secure?

Maybe I'm missing something here. By "input mechanism", do you only
consider inputs entered by a human, not taken from other systems?
