Claim One:
1. A method for generating an identifier for a sensor, comprising: accessing, by a computing device, sensed information for each pixel from a plurality of pixels of the sensor for an at least one sensing environment; determining, by the computing device, a first variance representing a variation in the sensed information for a first subset of the plurality of pixels using the sensed information for each pixel from the first subset of the plurality of pixels of the sensor; determining, by the computing device, a second variance representing a variation in the sensed information for a second subset of the plurality of pixels using the sensed information for each pixel from the second subset of the plurality of pixels of the sensor, wherein the first subset of the plurality of pixels is different from the second subset of the plurality of pixels; determining, by the computing device, a pixel identifier value for each pixel from a third subset of the plurality of pixels by comparing the sensed information for each pixel from the third subset of the plurality of pixels with the first variance and the second variance; and generating, by the computing device, the identifier using the pixel identifier values for each of the plurality of pixels from the third subset of the plurality of pixels.
