Artistic screening is a new halftone technology for producing an illusion of continuous tones by creating artistic screens that may take any desired shape and screening effects. This screening technology is tuned to convey additional information for artistic purposes, which is desirable for digital anti-counterfeiting in today’s printing industry. In order to achieve better anti-counterfeiting results, a novel data hiding algorithm is proposed by combining the artistic screening technology with digital watermarking. We present a digital watermarking algorithm in artistic screening images that divides the images into blocks and embeds a fixed number of bits in each block by changing some pixels in that block. Experiments show that watermarking-embedded artistic screening image is good at securing data hiding results and tampering of content can be detected successfully.
