Security and/or value document, with security features and with a verification element for verifying the security feature is disclosed. Integrated into the security and/or value document at different positions is at least one verification element and at least one security feature to be verified by the verification element. When the verification element and the security feature are only superimposed, verification takes place.

Security and/or value document

A security document with optically excitable dyes for authenticity checking. Dyes are applied to or embedded in the security documents. The dyes are advantageously embedded in a carrier material which in conjunction with the dyes forms a laser-active element. Certain optically excitable dyes are incorporated in a security document in such a way that when the security and/or sensitive document is optically excited, the dyes embedded in the security and/or sensitive document resonate with the material of the securities and secure documents, so that a well-defined narrow spectrum of all excited materials is emitted.

Security document with optically excitable dyes for authenticity check

A process is provided for securing products against forgery with machine-readable security features, which guarantees inexpensive security features with a high degree of security against forgery. The product to be secured includes at least one superconductive material possessing defined and reproducible, specific properties in at least one area.
