摘要:
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.
摘要(中):
这里描述的技术使用传感器中的变化来生成传感器的标识符。 每个传感器可以由子感测单元组成,称为像素,其可以显示其从一个像素到另一个像素的感测能力的变化。 本发明的实施例描述了在生成传感器的标识符时使用每个像素的相对方差(相对于整个传感器或/和传感器的一部分)的方法。 在一个实施例中,该方法可以从传感器获得与多个像素相关联的信息,从多个像素的子集中检测与每个像素相关联的信息的变化,并使用检测到的变化生成传感器的标识符 与来自多个像素的子集的每个像素相关联的信息。
