We present a True Random Number Generator (TRNG) using the images taken by web or mobile phone cameras. We use all three RGB color channels to obtain the random numbers whereas previous studies used only one. We investigated the physical and statistical properties of the random noise in a digital photograph obtained by a camera system, and we made several approximations to efficiently collect the best random signals from the pixels in the images to map them to random sequences. In short, the… CONTINUE READING
