I don't know, maybe it is. Maybe the politics of our world simply are that cynical and won't allow for such a thing to exist. But I guess I'm hoping it isn't. I'm trying to imagine how a non-authoritarian institution would work; it wouldn't have the "authority" to compel anyone to turn over their data, but just about everyone would have enough trust in the community and its decision making process to be okay with it.…
What if information could be revoked? Imagine the government suspects me in some investigation. I give them a key that gives them all information about me and my recent activities. Then once some period elapses, I revoke that key and they no longer have any of that information. Nor, of course, were they able to copy or independently distribute it in any way when they had it. This is probably pure fantasy, but if ther…
The simple example would be "I'd like to send indigochill a gift", which would send a request to your API (with some notification for you to approve or deny receiving said package) and return an id that could be written or printed on an envelope. That id is unique and the mail service would scan the id and the package would be routed. And the mail carrier would scan the id and get an actual address (or a blip on their map of the block or something). Nobody along the way has learned your address or name or anything - nor do they know my address, which is just another unique id.
There are some very interesting implications in that data can become stale so quickly. If you approved of receiving the package but were out of town for the week, the package could be routed directly to you without any interaction whatsoever. Nobody along the way would know the difference between your home or your hotel room.
The same could easily be done for lots of personal data. Phone numbers, email addresses, etc. All your shopping history could be stored on your own private data store and the local grocery stores would send out a mailer "Address this mailer to all people in the neighborhood who have purchased discounted burgers in the past month". The store doesn't know who is getting the flyer, but the people who would be likely to use a coupon for buying burgers would get a notification and likely go buy some burgers on sale - or reject the notification and not be bothered - to the savings of the store and the recipient.
Social Media could still exist with this sort of thing but the services would be querying engines rather than the creepy data warehouses that they've become.
This of course gets significantly harder with the queries this article is about, but the idea is the same. Instead of "give me everyone's location for the past month", the request would be "give me the anonymized ids of people who have been to x locations for x amount of time within x amount of space between one another". The response would provide data that could be used for the purpose in question, but the underlying data remains private.
I've been pondering this idea on random occasion for about 15 years, but I don't care enough about it to make it my life's work. But I sure would like to live in a world with that level of data ownership and privacy.
