Abstract: A liveness-detection method and/or system is disclosed. A method of detecting liveness can comprise obtaining a single ultrasonic image of a biometric object. The single ultrasonic image can be subdivided into a plurality of overlapping sample blocks. Feature vectors can be extracted in a spatial domain and a frequency domain from each of the plurality of sample blocks. The feature vectors can be compared from each of the plurality of sample blocks to a classification model.

Abstract: Disclosed is an apparatus and method for automatically enabling a touchscreen of a mobile device based on detection of the presence of a human finger. A mobile device can capture an image of an object with a fingerprint sensor. The mobile device may then enable a touchscreen display of the mobile device in response to a determination that the object captured within the image is a specific type of object.

Abstract: A method of determining whether a biometric object is part of a live individual is described. In one such method, image information is acquired from the biometric object by using a sensor, such as an ultrasonic sensor. The image information may be analyzed in at least two analysis stages. One of the analysis stages may be a temporal analysis stage that analyzes changes in the image information obtained during a time period throughout which the biometric object was continuously available to the sensor. For example, a dead/alive stage may analyze differences between image information taken at two different times in order to identify changes from one time to the next. Other stages may focus on aspects of a particular image information set, rather than seeking to assess changes over time. These other stages seek to determine whether an image information set exhibits characteristics similar to those of a live biometric object.

Abstract translation: 描述了一种确定生物体对象是否是活体个体的一部分的方法。 在一种这样的方法中，通过使用诸如超声波传感器的传感器从生物体对象获取图像信息。 可以在至少两个分析阶段中分析图像信息。 分析阶段之一可以是时间分析阶段，其分析在生物测定对象连续可用于传感器的时间段期间获得的图像信息的变化。 例如，死亡/活跃阶段可以分析在两个不同时间拍摄的图像信息之间的差异，以便识别从一次到另一次的变化。 其他阶段可能侧重于特定图像信息集的方面，而不是设法评估随时间的变化。 这些其他阶段寻求确定图像信息集是否表现出与活体生物体对象相似的特征。
