Arduino code safety

I am making a commercial product in transportation field and my product contains two arduinos (mega and uno) in my design box with few other components. Is there any way to make my code safe from outsiders because my box would be installed on the road and anybody can take my code??

plx help

It is very difficult to get the code out once loaded. It is not worth the effort unless it is something of interest to the defence services!


"plx" ?
