I had not thought about the possibility of hacking and stealing that information, but obviously that is within the possibilities.

It is complicated, since if it is true that the interne, the chain of blocks has come to give us some degree of freedom, possibility of breaking many borders, it is also true that the information has been put on a silver platter for many to use. in his favor, even without prior consent.

There are other options to check that you do not abuse a system, without needing to provide so much information.

Thank you very much for your contribution @ketcom
