Dividing Trust

VPNs were not invented for privacy, despite the name – they were invented for security. Nevertheless, in recent years, they have been touted as privacy tools to thwart rampant and fanatical data gathering. With a regular VPN, this really just means you’re shifting your trust from your internet service provider to your VPN provider. But what if your encrypted data traffic was actually divided between two separate companies? The split trust model is a powerful way to protect your privacy and it’s the key technology behind new services like Apple’s Private Relay and Obscura VPN. Today we’ll discuss the benefits of this approach with Obscura’s founder, Carl Dong.
