Title: RETROFIT TO PROTECT IMPLANTED DEVICES (E.G., PACEMAKERS) FROM UNAUTHORIZED MANIPULATION
Abstract:
An implantable device that (a) has an analog input configured to detect analog electrical signals and (b) is configured to accept RF commands can be retrofitted to prevent unauthorized access by modifying the software of the implantable device to (1) accept control commands that arrive via the analog input and (2) ignore control commands that arrive via the RF transceiver. Ultrasound communications can then be detected and inductively coupled onto a lead that is connected to the analog input. In some embodiments, the modified implantable device can only be controlled via ultrasound signals at all times to improve security. In other embodiments, the modified implantable device can only be controlled via non-ultrasound signals (e.g., RF signals) for short periods of time after the system has been unlocked in response to receipt of a specific ultrasound signal.
