Non-contact home-based sleep monitoring will bring a paradigm shift to diagnosis and treatment of Obstructive Sleep Apnea (OSA) as it can facilitate easier access to specialized care in order to reach a much boarder set of patients。 However， current remote unattended sleep studies are mostly contact sensor based and test results are sometimes falsified by sleep-critical job holders (driver， airline pilots) due to fear of potential job loss。 In this work， we investigated identity authentication of patients with OSA symptoms based on extracting respiratory features (peak power spectral density， packing density and linear envelop error) from radar captured paradoxical breathing patterns in a small-scale clinical sleep study integrating three different machine learning classifiers (Support Vector Machine (SVM)， K-nearest neighbor (KNN)， Random forest)。 The proposed OSA-based authentication method was tested and validated for five OSA patients with 93。75% accuracy using KNN classifier which outperformed other classifiers。
