Abstract
A computer-implemented method for introducing variation in sub-system output signals to prevent device fingerprinting may include (1) intercepting, on a computing device, an output signal sent from a sub-system device on a computing device to a software component on the computing device, (2) identifying a margin of error for the output signal, (3), creating a modified output signal by introducing variation into the output signal in such a way that (a) the variation does not exceed the margin of error for the output signal and (b) the modified output signal cannot be used to identify the computing device, and (4) sending the modified output signal to the software component. Various other methods, systems, and computer-readable media are also disclosed.
