It's a good idea and we could have data brokers built into this, software that filter out the data to companies that request it from this central store. For example my bank doesn't need my exact location coordinates so I will only let them have generalised version to 20 miles accuracy. An age verification service should only get a yes or no. The police shouldn't get all details of my medical records, just the basics like if I'm diabetic or allergies. Give the users control over their data
