“Everyone’s car generates a lot of data every day,” points out Jun Li, founder of the open-source digital identity blockchain Ontology. The automotive sector is one in which his company’s ID solution has a clear use case, as each driver’s data can be stored and used to calculate insurance premiums according to actual driving behavior. “Some insurance companies will put telemetry devices on the cars to collect your driving information. Every year, your insurance pricing will be based on your behavior data.” For Li, this is a positive development because good drivers will receive well-earned discounts on their insurance payments. But what if someone does not want an insurance company to access their driving records?
