When we started this project, "privacy by design" was our key guiding principle. This means that with every decision we took (and still are taking), potential privacy issues are thoroughly considered and define the decisions we make. Because, once again, we have absolutely no interest in identifying exactly what a person is doing in a particular room. We are only interested in how many people are in a room at various moments.
We are aware that some sensors, especially the people counting ones, make use of recognition technology. Based on that, we decided not to install sensor models that generate images, made by hi-resolution cameras in a frontal position. Even though, this registration method may provide fully accurate results, we decided that these kinds of images pose inacceptable potential privacy risks.
Furthermore, images processed by dedicated software (linked to the sensor generating the data) are left unselected, since we consider data collection and processing beyond the sensor to be a possible source of privacy risks. Finally, we only choose sensors that have proven to be purpose built and professionally designed, so we ruled out all combinations of off-the-shelf hobbyist hardware.
Although we did our utmost to protect your privacy, we do connect software and hardware to our network with "Internet of Things-like" devices. For this reason, we are closely monitoring the data generated by the sensors during this pilot project and will adjust configurations when required.
