Abstract
A personalizable security document including a combination of two secure features, namely, a laser-engravable material embedded in a substrate of the security document and an embossed pattern formed in an outer surface of the substrate and overlapping the laser-engravable material. The combination of the laser-engravable material and the embossed pattern may result in a change in appearance of the embossed pattern when the security document is viewed at different observation angles. Security can be further enhanced by providing a watermark below the laser-engravable material. Further, by providing appropriate structures in the embossed pattern and the laser-engravable material, a personalized security document exhibiting a moiré effect can be obtained.
