these generators prefer to sacrifice the possibility of error

correction for attractive design. Recently, the rich QR code,
which adds the significance without losing error correction
capacity, was introduced [3].

PS Process Impact: Any QR code creation suggests a printing

procedure and a checking process. The PS procedure in
verification situations are considered as a physical unclonable
capacity . The finished examples, that we propose to use in
2LQR code, are touchy to the PS procedure. In this area, the
progressions included amid the PS procedure are talked about,
keeping in mind the end goal to get it why the yield pictures
experience the ill effects of this procedure. The PS procedure
produces obvious and undetectable picture alterations, which
can be caused by resampling intrinsic to the PS procedure,
inhomogeneous lighting conditions, ink scattering, fluctuating

is the reason the bends have a place with them two [5].
