  Random numbers form an intrinsic part of modern day computing with
applications in a wide variety of fields. But due to their limitations, the use
of pseudo random number generators (PRNGs) is certainly not desirable for
sensitive applications. Quantum systems due to their intrinsic randomness form
a suitable candidate for generation of true random numbers that can also be
certified. In this work, the violation of CHSH inequality has been used to
propose a scheme by which one can generate device independent quantum random
numbers by use of IBM quantum computers that are available on the cloud. The
generated random numbers have been tested for their source of origin through
experiments based on the testing of CHSH inequality through available IBM
quantum computers. The performance of each quantum computer against the CHSH
test has been plotted and characterized. Further, efforts have been made to
close as many loopholes as possible to produce device independent quantum
random number generators. This study will provide new directions for the
development of self-testing and semi-self-testing random number generators
using quantum computers.
