    • A method and apparatus for determining a digital signature from an article. A coherent light source directs a beam to illuminate the article and a detector arrangement collects data points from light scattered from many different parts of the article to collect a large number of independent data points, typically 500 or more. By collecting a large number of independent signal contributions specific to many different parts of the article, a digital signature can be computed that is unique to the area of the article that has been scanned. This measurement can be repeated whenever required to test authenticity of the article. Using this method, it has been discovered that it is essentially pointless to go to the effort and expense of making specially prepared tokens, since unique characteristics are measurable a in a straightforward manner from a wide variety of every day articles.

    • There is described a signing film wherein provided on a background of the signing film is a decorative printing which forms a security feature and which fluoresces when viewed under UV light. So that the decorative printing which fluoresces under UV light is not to be perceived when viewing the surface of the signing film at different viewing angles in ambient light, it is proposed that the background of the signing film has at least two background layers and between them the decorative printing comprising a lacquer which contains a high-viscosity binding agent and is mixed with pigments which fluoresce under UV light, so that after the printing operation and the drying operation it is of a small layer thickness as a consequence of the high viscosity.
    • 描述了一种签名膜,其中在签名膜的背景上提供了形成安全特征并在UV光下观察时发荧光的装饰性印刷。 因此,在环境光下以不同的视角观看签名膜的表面时,不会感觉到在UV光下发荧光的装饰性印刷物,所以建议签字膜的背景至少有两个背景层和它们之间 该装饰性印刷品包含含有高粘度粘合剂的漆,并与在紫外光下发荧光的颜料混合,使得在印刷操作和干燥操作之后,由于粘度高而具有小层厚度。
