| dc.description.abstract | The objective of this research is to embed information in personalized stamps by modified digital halftoning techniques. The displaced and deformed halftone dots are used to encode data in the personalized stamps. Hidden information can be retrieved by either an optical decoder or digital image processing techniques.The results show that personalized stamps with value-added features like data hiding or digital watermarking can be successfully implemented. | en_US |
