The HeadCounter device by Blimp is privacy compliant. What does this mean?
Head-Counter is a device produced and sold by Blimp with the aim of providing its customers information on the flow and density of people entering its field of view. The device falls within the broader category of Digital Signage devices. Head-Counter uses face detection algorithms to carry out its measurements. These algorithms refer to technologies that detect the presence of a human face in an image, without identifying it. The image analysis and acquisition system developed by Blimp can take photographs in a certain area. These are then processed by a calculation unit inside the measurement device, which extracts the information of interest.
Aggregation and anonymization
Aggregation and anonymization operations allow to extrapolate the audience information from the photographs, without any identifying element. Information includes: the number of faces, the number of pedestrians or vehicles in an area, the number of individuals belonging to a specific gender (for example: 500 men and 200 women). The acquisition has a limited duration and takes place at the very moment in which the photograph is acquired. No personal data remains on the hard drive and no data is transferred outside the measurement device. The extrapolated data remain exclusively in the volatile memory (RAM) of the Main Board for the time necessary for their processing, maximum 500 milliseconds. Afterwards, they are immediately eliminated. It is not possible to access the Main Board from the outside or remotely: during standard use, communication is one-way. Access to the Main Board is only possible during the configuration phase, under the explicit request of the customer and through specific commands.
