    • Methods and Apparatus are provided for fake fingerprint detection. In one embodiment, an apparatus for fake fingerprint detection includes a prism having a first side configured to be touched by a fingerprint, an IR LED located near the second side of the prism, a light source located near the third side of the prism, where both the IR LED and the light source are configured to illuminate the fingerprint simultaneously to produce a captured image of the fingerprint, one or more lenses configured to direct the captured image of the fingerprint for storage, one or more CMOS sensors configured to collect the captured image of the fingerprint for analysis, and a controller configured to determine validity of the fingerprint using the captured image.
    • 提供了伪指纹检测的方法和装置。 在一个实施例中,一种用于假指纹检测的装置包括具有被指纹触摸的第一侧的棱镜,位于棱镜第二侧附近的IR LED,位于棱镜第三侧附近的光源, 红外LED和光源被配置为同时照亮指纹以产生指纹的捕获图像,一个或多个透镜被配置为将捕获的指纹图像引导存储,一个或多个CMOS传感器被配置为收集捕获的指纹 用于分析的指纹的图像,以及被配置为使用捕获的图像来确定指纹的有效性的控制器。
