  • Patent number: 10433750
    Abstract: Disclosed are a method for generating an electrocardiogram for personal identification and a method for identifying a person using the electrocardiogram. The electrocardiogram generation method generates a normalized electrocardiogram by extracting single-cycle electrocardiogram signals meaningful for personal identification from an electrocardiogram of a person and by connecting the extracted single-cycle electrocardiogram signals arranged in temporal order. Therefore, the electrocardiogram generation method dramatically increases identification accuracy in personal identification.
