Anyone who’s watched Top Gear may remember the episode where they bought used cars then had them inspected for biological matter left behind by the previous owners. The results weren’t pretty.
Well, CNN posted an article this morning about digital matter that can be left behind when you buy a used car that has connectivity options, and it also applies to connected houses. In short, the previous owners of both may still have access to them even after the sale has gone through.
For cars, you have to go to the dealership to have the connection broken. The article says that a factory reset will only reset the car and not the connection that might still exist through an app on a tablet or smartphone.
