Hi! I'm a Biomedical engineer trying to hack into your biosignals. #geek, #avgeek

capcarr··on CardioID Technologies – Pervasive heart signals
We'll post some links, thanks for the suggestion.

Ok, thanks. I should've read the guidelines more carefully.

We were already planning on posting a more detailed overview.

We have several business partners, for which we produced prototypes to be integrated into their systems. These prototypes include a signal acquisition hardware interface, a processing unit, and all accompanying software and APIs.

We do not currently have a product directly for sale to individual users.

Medical certification is something that we're not pursuing at the moment. For now, we intend to raise alerts to the user, in case we detect something suspicious, referring them to their medical doctor. We do not claim to detect cardiac pathologies that are rare, and need several ECG derivations to be correctly diagnosed.

What we do offer is the possibility of more frequent ECG monitoring, beyond the 10 second ECG exam that most people do only once or twice per year. For example, driving is a stressful environment, where a major cardiac event is more likely to occur. In a car with our technology, we would be able to detect when that event happens, thus preventing a crash by automatically stopping the car, and calling emergency services.

Regarding signal variability due to medication and other pathologies, that's something we have to account for, with robust feature extraction methods that are invariant to these changes, or adapt to them.

Yes, you're right. That's why we're primarily targeting a B2B market. Imagine that a gym has machines with our technology embedded. The gym's users would be able to seamlessly track their workout across different machines, just by using them as they normally would, no need for extra weight.

Note that, for continuous ECG monitoring, you need skin contact with 2 electrodes, from different limbs. That's why with Nymi, authentication is performed only once when the user puts it on, with one finger touching the visible electrode (the other electrode is on the underside of the band). In this case, there is no continuous verification of identity, or other parameters.

We do have research collaborations with cardiologists, but we consider them to be advisers, not officially part of the team. However, two team members are biomedical engineers, with expertise in the medical field.

We are aware of Nymi, they have cited some of our ECG biometrics research papers, and we theirs. But Nymi makes the user constantly wear a band. As soon as you take off the band, their authentication stops working. Also, you have one more gadget to charge. In CardioID's case, the ECG sensors are embedded into everyday life objects, so the system is ready whenever the user wishes it. Beyond that, we also continuously track other heart parameters, like heart rate and cardiac arrhythmias.
