Abstract:
1. A method for ballistocardiogram-based personal authentication, comprising: detecting a ballistocardiogram training signal of a person to be registered; extracting a training feature from the detected ballistocardiogram training signal; generating training data for personal authentication, based on the extracted training feature; detecting a ballistocardiogram authentication signal of a person to be authenticated; and comparing the ballistocardiogram authentication signal and the training data to determine an authentication of the person to be authenticated, wherein the extraction of the training feature includes: extracting at least one period from each ballistocardiogram training signal; dividing the extracted period at regular intervals to select a plurality of feature extracting points; and calculating characteristic values of the plurality of feature extracting points, wherein the characteristic values include height values and slope values of the feature extracting points.
