In November Crowdscan has joined the DASH7 Alliance. Crowdscan is a startup from Antwerp, Belgium and is a spin-off of the University of Antwerp and Imec. Based on six years of research at the University of Antwerp and imec, CrowdScan has developed a system to measure crowd densities without using camera images, mobile phone data or other privacy-sensitive information.
They developed a wireless crowd density system that predicts size and density of large crowds. The capacity is measured in terms of humans per m². Their measurement methodology is based on radio frequency signals using #DASH7 to derive crowd size information.
They do not make use of camera images or any type of device that needs to be connected to an individual, this makes it fully anonymous and privacy non-intrusive.
