A Sample for Secure Sensor Data Collection: Data Secured Fall Prevention and Fall Detection Sensor

Falling costs and shrinking sizes of electronic components have led to an increase in the wearable sensor applications. Among other areas, wearable sensors are also used in medical health care applications; capitalizing on their property of mobility. But, mobile sensors use wireless technologies in transmitting their data. Thus, sensitive patient data travel through many unknown users, until reaching the data collector. In present study, a sensor designed for preventing and detecting patient falls is presented, where only encrypted data is transmitted. The capabilities, accuracy, sensitivity and specificity performances of the proposed design are compared with previous works. In addition, the presented design's results, advantages and superiorities are discussed.
