Method & Evidence

AimTo develop and evaluate an electronic method for authenticating printed documents using latent security elements enhanced with fractal grids.

MethodExperimental research with comparative analysis.

ProcedureSecurity elements with overlapping fractal grids were designed electronically and then printed onto various paper samples using an offset printing machine. The printed security features were then subjected to copying. Original and copied prints were compared using an electronic pixel-by-pixel comparison method based on the peak signal-to-noise ratio (PSNR).

Sample15 paper samples

ContextDocument security and anti-counterfeiting technologies.

Variables

IVPresence and type of fractal grid overlay on latent security elements.

DVDistinguishability between original and copied documents (measured by PSNR).
