B-1-2 Proposal of a biometric authentication method based on Bhattacharyya distance between color histograms in hand image

Abstract

We research and develop a novel biometric authentication to compare the advantage of the technique with typical methods. In the previous works, we presented a personal identification method with the image of the hand shapes on the keyboard. It is available to construct in a low-cost way and it is less stressful for users than ordinary passphrase method. In this article, we described the proposal of a biometric authentication method based on Bhattacharyya distance between color histograms in hand image, and also we discussed the implementation for the practical use. In addition, we experimented to evaluate the proposed method, and as the result, it was confirmed the precision of the authentication in the ideal environment was 100% whereas that one in real environment (at the real-time processing) was 78%. It was suggested that the implementation of our method was valid computational cost.
