This talk is about data ownership and portability in the context of the Internet of Things and wearable health/sports devices. Currently, companies building hardware like the Jawbone UP or SmartThings home automation system are trying to own the whole ecosystem around the device, including the data, and want to lock you in. Of course this leads to many problems such as when a company shuts down, you lose the data in the system.
But what if there was a way to allow users to own the data being collected by these devices, and people could choose which other applications/aggregators/social networks to share the data with? This would lead to a much better ecosystem of devices and services, where users were at the center. I've been experimenting with this kind of thing for years, and have a lot of my own personal data collected from these services, and some of it is even published on my website.
