About this technology
Overview
NASA has developed a method for verifying the identity of a person based on his or her heartbeat electrocardiogram signal. The technique uses an algorithm that has been shown to be more reliable than other current procedures, such as fingerprint verification, retina verification, or detecting biometric identifiers from heart signals. It eliminates artifacts and abnormal beats, thereby reducing overall error. The process automatically extracts from one or more electrocardiographic leads (channels) a set of biometric features which are characteristic to an individual and can be employed to verify the identity of one individual or to identify an individual from a group. The electrocardiographic signal is recorded in each lead from a pair of electrodes placed on the skin of the individuals arms or legs. Each electrocardiographic lead characterizes the hearts electrical vector as projected on a separate dimension. This allows a multidimensional characterization of the hearts electrical activity, which can result in improved subject verification performance.
