Abstract: A computer-implemented method, comprising receiving, by a computer system, binary image data, the computer system configured to detect a pixel value in the binary image data to represent a non-machine language value related to the binary image data; determining, by the computer system, that the binary image data further comprises at least a pixel value that is altered in a manner to change the non-machine language value related to the binary image data when read by an image recognition system; and alerting, by the computer system, to the image recognition system to review the binary image data.
