Unclonability of Biological Physically Unclonable Function (Bio-PUF). a False color optical images and corresponding Bio-PUFs generated using post-colonization T cell population i.e. taken 24 h after cell suspension from five independently and separately prepared wells. A total of 15 Bio-PUFs, 3 from different locations of each of the 5 wells, were analyzed. b Entropy plot showing high-entropy values for all the 64 1D keys generated from 15 different Bio-PUFs. c Probability mass function (PMF) of inter-Hamming distance (Hinter) between the 1D keys associated with the 15C2 pairs of Bio-PUFs. d Correlation coefficient colormap between the Bio-PUFs
