Abstract
The present disclosure relates to an information processing device, an information processing method, and a program that enable generation of stable PUFs. The information processing device includes: a reading unit that reads output data from a predetermined element a plurality of times; an average value calculation unit that calculates average values of the output data read by the reading unit; a median calculation unit that calculates the median of the average values calculated by the average value calculation unit; and a PUF generation unit that generates a physical unclonable function (PUF) by comparing the median with the average values. The predetermined element is an image sensor, and the reading unit reads output data from the image sensor when the image sensor is shielded from light. The present technology can be applied to imaging devices, for example.
