> This study showed that human DNA can be collected from air and on surfaces that move air, such as air conditioner units, and can identify the usual users of the space as well as frequent visitors. DNA accumulated within a fairly short period of time with owners being identified after only 4 weeks of use of the tested space. So this doesn’t seem like it would be adequate to identify criminals who visit a space one time. But I can think of various ways in which this collection might be abused - from selling information to data brokers for advertising or surveillance of regular visitors.
