Abstract: A mobile device may perform authentication with an authenticating entity. The mobile device may comprise a plurality of sensors and a processor. The processor may be configured to: receive an authentication request from the authenticating entity requesting authentication information; and determine if the authentication request satisfies predefined user privacy preferences. If so, the processor may be configured to: retrieve the authentication information from at least one sensor to form a trust vector in response to the authentication request and to command transmission of the trust vector to the authenticating entity for authentication.

Abstract: Some methods may involve determining whether an object is positioned on or near a portion of a fingerprint sensor system. If an object is positioned on or near the portion of the fingerprint sensor system, an acoustic impedance of at least a portion of the object may be determined. Based at least in part on the acoustic impedance, it may be determined whether the object is a finger.

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: Techniques described here use variations in the sensor to generate an identifier for the sensor. Each sensor may be comprised of sub-sensing units, called pixels that may demonstrate variation in their sensing capability from one pixel to another. Embodiments of the invention, describe a method for using the relative variance of each pixel (relative to the whole sensor or/and a portion of the sensor) in generating an identifier for the sensor. In one embodiment, the method may obtain information associated with a plurality of pixels from a sensor, detect variations in the information associated for each of the pixels from a subset of the plurality of pixels and generate an identifier for the sensor using the detected variations in the information associated with each of the pixels from the subset of plurality of pixels.

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。
