Privacy-enabled system based on Elliptic Curve Cryptography to reduce risks of contagion in pandemics

The increase in the frequency of pandemic crises in recent years, with the current example of COVID-19, leads to the need of having technological tools that help to control the spread of these diseases in the first instance, and to avoid the generation of new outbreaks in the phases of back to normality. The main issue in these tools is the how to make their effectiveness compatible with privacy. In this work we present a system enabling secure distribution of people in closed environments such as public transport, restaurants or cinemas while maintaining privacy of health data. The system is based on Elliptic Curve Cryptography and it has been implemented on low-cost FPGA devices.
