The modified digital halftoning technique is applied to covert the continue image into binary image with titled halftone dots. Both the figurative watermark pattern and the hidden data according to the pseudo-random number are encoded in the binary image printed. The hidden image and data can detected the by human eyes, optical decoder and digital image processing. The double encrypted binary image not only has the bar code capability but also displays meaningful image. 王希俊 2007 學位論文 ; thesis 62 zh-TW |
