Did you know that “Heartbeat biometric identification is considered to be very accurate and at a similar level to fingerprints or retina recognition”? Food for thought.

@prologic@twtxt.net yeah, or any fitbit… measuring the heartrate is easy and cheap, and depending on the accuracy level it can be as cheap as… well, PPG, and any phone with a camera and flashlight can do it. But only yesterday I connected the dots on my mind regarding the sort (and potential uses) of the data being collected as soon as someone tries out a new band or watch.

@prologic@twtxt.net it is collected, we just don’t know exactly what, how, where, what for or how long. A slightly tangential but good read about fitbit’s data collection here.
