The Bluetooth-based digital tracing is superior to traditional contact tracing methods in a few ways: If an individual “A” is diagnosed with COVID-19, an immediate notification can be sent to all contacts, asking them to self-quarantine. By populating an online database, engineers could construct an entire population tracing record. Next, each phone would construct a record of all the other phones it came in contact with. Simultaneously, every phone would listen to and record all the encrypted signatures they are receiving from nearby devices. The short random messages form an encrypted signature. Every smartphone Bluetooth radio would be tuned to broadcast short random messages to nearby phones. If we reprogram smartphone Bluetooth radios in a certain way, we can potentially use smartphones to detect which individuals came in direct contact with each other.įrom a technical standpoint, the theory is simple. Every new smartphone is equipped with a Bluetooth radio, and almost everyone has a smartphone. Additionally, as mentioned earlier, there is not sufficient data to legitimately back up claims regarding how this virus is spreading.īluetooth Low Energy (LE) is a ubiquitous, widely-deployed, and mature connectivity technology with enormous potential to enable digital tracing.

Available techniques are error-prone, which poses the risk of false-positives and false negatives. Furthermore, engineers don’t yet have proven, mature tracing technology. Tracing interviews conducted by medical professionals are a fundamental process in contact tracing and should be used in tandem with technology. 【Download】Aprisa place-and-route tool for low-power SoCsĭigital tracing should be incorporated into a traditional contact tracing procedure and not replace it.
