In the technical field of identification, the research of ECG technology is an emerging biometric identification technology. ECG (Electrocardiogram) signal is a kind of biological information with the features of random, uniqueness and difficult to be duplicated and forged, and is may be utilized as biological identity authentication. The characteristics of ECG signal and its feasibility as an identification method are analyzed in this paper. Also introduces the current ECG-based identification
