    • A method capable of determining fingerprint authenticity is disclosed. The method includes capturing a fingerprint image, performing an analysis program when executed analyzing the fingerprint image using a first color model to obtain a first chromaticity coordinate corresponding to the fingerprint image, performing a conversion program when executed converting the first chromaticity coordinate into a second chromaticity coordinate, performing a verification program when executed determining whether the second chromaticity coordinate satisfies a second predetermined skin color threshold, when the second chromaticity coordinate satisfies the second predetermined skin color threshold confirming the fingerprint image is authentic, and concluding the fingerprint image is forged when the second chromaticity coordinate fails to satisfy the second predetermined skin color threshold.
    • 公开了一种能够确定指纹真实性的方法。 该方法包括捕获指纹图像,当使用第一颜色模型执行分析指纹图像时执行分析程序以获得与指纹图像相对应的第一色度坐标,当执行将第一色度坐标转换为第二色度时执行转换程序 坐标,执行确认程序时,判定第二色度坐标是否满足第二预定肤色阈值时,第二色度坐标满足第二规定肤色阈值,确认指纹图像是真实的,并且当指纹图像伪造时 第二色度坐标不能满足第二预定肤色阈值。

    • A detection device including a light guide element, a sensing element, a surface plasma resonance layer and a spatial filter element is provided. The light guide element has a top surface and a bottom surface opposite to the top surface. The sensing element is disposed beside the bottom surface of the light guide element. The surface plasma resonance layer is disposed on the top surface of the light guide element and is adapted to receive biopolymers. The spatial filter element is disposed between the bottom surface of the light guide element and the sensing element. The spatial filter element has a plurality of first light channels and a plurality of second light channels. The plurality of first light channels extend in a first direction, the plurality of second light channels extend in a second direction, and the first direction and the second direction are intersected. A normal direction of the top surface of the light guide element and the second direction form an included angle β, and the included angle β corresponds to a resonant angle γ of the surface plasma resonance layer.
