wow! I'd looked over the patent number and it seems things are coming together quite quickly.

From the patent details section it appears a hardware based mechanism which senses body activity and transmits data back to a device is included in the scope of this invention:

>For example, a brain wave or body heat emitted from the user when the user performs the task provided by an information or service provider, such as viewing advertisement or using certain internet services, can be used in the mining process. Instead of massive computation work required by some conventional cryptocurrency systems, data generated based on the body activity of the user can be a proof-of-work...

>A sensor communicatively coupled to or comprised in the device of the user may sense body activity of the user. Body activity data may be generated based on the sensed body activity of the user. A cryptocurrency system communicatively coupled to the device of the user may verify whether or not the body activity data satisfies one or more conditions...

> Sensor 140 may include, for example, but not limited to, functional magnetic resonance imaging (fMRI) scanners or sensors, electroencephalography (EEG) sensors, near infrared spectroscopy (NIRS) sensors, heart rate monitors, thermal sensors, optical sensors, radio frequency (RF) sensors, ultrasonic sensors, cameras, or any other sensor or scanner that can measure or sense body activity or scan human body...

>Accordingly, aspects of the present disclosure may take the form of an entirely hardware embodiment, an entirely software embodiment (including firmware, resident software, micro-code, etc.) or an embodiment combining software and hardware aspects that may all generally be referred to herein as a “circuit,” “module” or “system.” Furthermore, aspects of the present disclosure may take the form of a computer program product embodied in one or more computer readable medium(s) having computer readable program code embodied thereon...

The patent disclosures above seems to scope in integrations with some technology that's been a focus of Microsoft Research & MIT. Notably, an invention that was funded by Gates Foundation for medical data-storage on humans which is a "new dye, which consists of nanocrystals called quantum dots, [that] can remain for at least five years under the skin, where it emits near-infrared light that can be detected by a specially equipped smartphone." [1] The primary application they talk about for this in the press release below is vaccinations, which seems to what many feel will be required to overcome the ongoing pandemic threat.

Interestingly, another program funded by Gates Foundation and Microsoft Research [2] is id2020.org, which aims to provide everyone digital certificates [3] for digital identity tracking based on blockchain technology. Id2020 seems to be the only organization that's in place to 'standardize' digital certificates globally as countries move toward adopting digital certificates as a mechanism normal life [4] [5]
