It's easy to feel anonymous in heavily trafficked areas like the Subway but a new facial recognition subway line in Brazil is aiming to change that.
The new technology has been implemented in São Paolo, Brazil and has since sparked a controversial discussion. The newly installed doors feature unique facial recognition technology that can track the mood of each rider, categorizing individuals as "happy, unsatisfied, surprised and neutral." In addition, the technology can track the number of unique visitors, while collecting data regarding the average age and gender of each guest.
Currently, Brazil has no laws to prohibit the use of this technology in an area as heavily trafficked and necessary as the subway. However, the Personal Data Protection Bill, which is currently under review, may lead to new regulations regarding the new facial recognition subway line.
