control system (1) comprising a
medical device (2) and a
medical device controller (4), the medical device controller comprising a communications module (17) including at least a
short range wireless communications capability for communication with one or a plurality of
consumer electronic devices (12) including any one of a smartphone, a
personal computer, a
smartwatch and a computer tablet, wherein each of the medical device (2) and the medical device controller (4) comprises a memory storing one or a plurality of journals (16) for exchange of journal entries between the medical device controller (4) and the medical device (2), and between said medical device controller (4) and said one or a plurality of
consumer electronic devices, the at least one journal (16) stored in the medical device controller (4), the
consumer electronic device (12), and the medical device (2), said at least one journal comprising past instructions exchanged between the medical device controller (4) and the consumer electronic device (12) and between the medical device controller (4) and the medical device (2), constituting a journal entries history, the method comprising: f) receiving in the medical device controller (4)
pairing parameters from a consumer electronic device (12); g) comparing in the medical device controller these
pairing parameters with
pairing parameters stored in the memory (14) of the medical device controller (4) during a pairing operation; h) receiving in the medical device controller (4) a journal entries history of said consumer electronic device (12) in case of a successful pairing operation; i) comparing in the medical device controller the journal entries history received from said consumer electronic device (12) with the journal entries history stored in the memory (14) of the medical device controller (4); j) validating a session between said consumer electronic device (12) and the medical device controller (4) for
data exchange if the journal entries history of said consumer electronic device matches the journal entries history of the medical device controller.
