User (U1) is a doctor, which is registered in the SUP2PER system by using professional medical identification card inserted in a card reader (already used in medical systems). User (U2) is a patient, with a unique medical identification number indicated in the health card and registered in the SUP2PER system by typing the number in the SUP2PER client installed on smartphone. Both users are identified by their unique numbers and SUP2PER system authorises their log-in. An authorised request from user U2 is then sent to a SUP2PER system that medical data are to be transferred to a secure medical system of user U1 in the medical record of user U2. Finally, a direct data tunnel is established and the user U2 can send data, encrypted by SUP2PER solution, to user U1. After the data has been exchanged, the direct tunnel is terminated and the connection is closed.
