Medical secrecy, processes and laws have indeed prevented SOME things, but a lot of things have gotten significantly better due to enhanced statistical models that have been implemented and widely used in real life scenarios.

To make this feasible (meaning that the TB of data and the huge computing effort is somewhere else, and I only have the mic (smartphone), we need our local agent to send multiple irrelevant queries to the mothership, to hide our true purpose.

Example: my favourite team is X. So if I want to keep it a secret, when I ask for the history of championships of X, I will ask for X. My local agent should ask for 100 teams, get all the data, and then report back for only X. Eventually the mothership will figure out what we like (a large wenn diagram). But this is not in anyone's interest, and thus will not happen.

Also, like this the local agent will be able to learn and remember us, at a cost.
