Abstract: Anti-counterfeiting technology has been widely used in many fields, especially in
printing industry for banknotes and security documents. This paper introduces an
anti-counterfeiting method with varied screening angle and gives the realization procedure of
this method. Firstly, the continuous-tone cover image is halftoned by ordered dithering
halftoning method with 0o and 45o screening angle, respectively. Then, a binary figurative image
which represents the hidden information is generated by using Photoshop software for serving as
a mask image. Finally, the latent image is generated by combining the two halftoning images with
different screening angle according to the figurative image. The diagonal edge detector is
designed for extracting the hidden information. The experimental result shows that the proposed
method can better generate the desired latent image and the hiding message can easily be
exposed by the simply image processing method. © 2012 IEEE.
