1. A liveness detection system comprising:

  • a video input configured to receive a moving image of an entity captured by a camera over an interval of time; and

    one or more hardware processors configured to;

    control a display to display, to the entity over the interval of time, at least one randomly selected word at a random location of the display;

    process the moving image to detect an eye and a mouth of the entity;

    compare;

    (i) movement of the mouth exhibited over the interval of time with the randomly selected word using a lip reading algorithm, to determine whether the mouth is speaking the randomly selected word in the moving image, and(ii) movement of the eye exhibited over the interval of time with the random location of the randomly selected word, to determine whether the eye exhibits an expected movement in the moving image, to thereby determine whether the entity is a living being; and

    grant or refuse an access request for the entity, the access request relating to a computer system, based on said determination as to whether the entity is a living being.
