摘要： A security document comprises a substrate (1) and an optical waveguide (7). Couplers (10a, 10b) are provided in the waveguide (7) for coupling light into and out of the waveguide. The couplers (10a, 10b) can e.g. by gratings, scattering objects, holograms, luminescent dyes or perforations. The authenticity of the document can be verified using methods based on the properties of the waveguide.

摘要： A method for verifying the authenticity of a security document by means of a camera-equipped cellphone comprises steps of acquiring a transmission mode image and a reflection mode image of the security document. Transmitted light through a plurality of perforations in a substrate of the security document is evaluated by means of the cellphone. Then, a relative positioning of the perforations with respect to a printed security features is determined, and the security document is considered “authentic” if the determined positions and the acquired images substantially correspond to pre-stored “templates” for the security document. The perforations are structured such that they are not visible to the naked eye of a human observer which makes it harder to counterfeit the security document.

摘要翻译：用于通过配备有相机的手机验证安全文件的真实性的方法包括以下步骤：获取安全文档的传输模式图像和反射模式图像。通过手机评估通过安全文件的基板中的多个穿孔的透射光。然后，如果确定的位置和所获取的图像基本上对应于安全文档的预先存储的“模板”，则确定穿孔相对于打印的安全特征的相对定位，并且安全文档被认为是“可信赖的”。穿孔结构使得它们对于人类观察者的肉眼看不到，这使得难以伪造安全证件。
