Abstract

Embodiments herein relate to sensor based authentication between an implantable medical device (IMD) and an external device. In an embodiment, the IMD includes a wireless communication module and an internal inertial measurement unit (IMU) capable of measuring vibrations, movement, or rotation. The IMD is configured to record an internal IMU signal from the internal IMU. The external device includes a wireless communication module and an external IMU. The external device is configured to record an external IMU signal from the external IMU. The system further includes a data processing system to receive a first level communication that can include the internal IMU signal, the external IMU signal, or both, compare data from the internal IMU signal with data from the external IMU signal, and authorize a second level communication based on results of the comparison step.
