Transporter Hack Scenerios/Rant

How many examples of teleporters/transporters work is to copy the object into data, destroy the original objects, transmit the data to landing point and use molecules there to build a new copy of the object.

Fine.

But what if someone hacks the data, and replaces it?

Say replace the data to say the object was a human with data for Vulcans, Kryptonians, a demon or an active mutant? What about replacing the data for a damage physical body for an old copy of the health one? Or replace an old body with a copy of a younger version of that body without affecting the mind? Replacing your body with a better looking one by teleportation, or even copying some else's body for various purposes including identity theft or spying.

Then there is the hacking of mental data or a person's mind during teleport. Adding, modifying, subtracting things like thoughts/memories/emotions/etc? It could do anything from adding and removing skills to total mind control potentially.

So why is this not more common in science fiction? I would make very interesting stories? So why not?
