This is a classic example of what I was referring to. You’re missing one very important point. Security is about only granting access to people chosen by the owner of the data. If you can think of a way to give access to one party not chosen by the owner, without also giving it to anyone else, well, you either know more than every specialist in the field or you’re suffering from dunning-kruger syndrome.
If you think this is possible, please be specific about describing the algorithm that you think will do this. This algorithm had also better not have a step that reads “trust the competence or the intentions of the people who are asking for it,” since you’re a fool, and ignorant of both current events and history, if you would trust either.
