I have both a positive answer to that and a negative answer to that.
I'll start with the negative. There is no way to guarantee that any bit of data, any string of characters you submit or that are identified with you, will not be propagated down the line to another company. Data multiplies. I see it all the time. There is just no way to prevent it. It's too prolific.
I do have a suggestion on how to work towards the goal of containing the amount of data that is multiplying out there for whatever purpose. That suggestion is to have on the books laws that have teeth. These companies will not deal with large databases of information if they know that it is a huge liability and a potential threat to their bottom line. It's not until the regulators can issue fines that affect profits and stock value that these companies will respect what the regulations say.
