SYSTEMS AND METHODS TO ACHIEVE ROBUSTNESS AND SECURITY IN MEDICAL DEVICES

Abstract:

According to some embodiments, a system, method and non-transitory computer-readable medium are provided comprising one or more heterogeneous data source nodes generating data associated with operation of the medical device; an abnormal state detection, prediction and correction module to receive data from one or more heterogeneous data source nodes; a memory for storing program instructions; and an abnormal state processor, coupled to the memory, and in communication with the abnormal state detection, prediction and correction module and operative to execute program instructions to: receive data from one or more heterogeneous data source nodes; receive a decision manifold separating a normal operating space from an abnormal operating space; perform a feature extraction process on the received data to generate at least one feature vector; determine, via the abnormal state detection, prediction and correction module, whether the feature vector maps to the normal operating space or the abnormal operating space in the decision manifold; and generate, via the abnormal state detection, prediction and correction module, a corrected value for the feature vector to map the feature vector to the normal operating space when it is determined that the feature vector maps to the abnormal operating space. Numerous other aspects are provided.
