Microsoft has proposed a system that can mine cryptocurrencies using data collected from humans as they exercise or read an advertisement.

In a patent application filed with the World Intellectual Property Organization (WIPO) Thursday, the American computer giant said sensors could detect activity associated with specific tasks – such as time spent viewing ads – and convert it into computer-readable data to solve computational problems, in much the same way as a conventional proof-of-work system.
