Use of communication equipment and method for authenticating an item, unit and system for authenticating items, and authenticating device
First Claim
1. A method for authenticating a security document with the help of a mobile communication equipment selected from the group consisting of a mobile phone, a handheld computer, an electronic organizer, an electronic terminal, and a camera, which is provided with access to a mobile wide area telephone network;
- said mobile communication equipment having an authenticity data captor which is either integrated into the mobile communication equipment or connected to the mobile communication equipment by a link selected from the group consisting of a wire link, a short-range radio link, and a short-range infrared link, said document having at least one marking selected from the group consisting of printed features and coatings, wherein said marking comprises a characteristic particle or flake pattern or at least one material selected from the group consisting of a magnetic material, a luminescent material and an infrared-absorbing material, said method comprising the steps ofdetecting a response signal, which is emitted by the said marking in response to an applied energy, and which is a physical characteristic of the group of characteristics consisting of spectrally selective absorption of electromagnetic radiation, spectrally selective emission of electromagnetic radiation, and measurable electric or magnetic characteristics with the help of the said authenticity data captor;
comparing the detected response signal to reference data; and
authenticating said detected response signal in the said mobile communication equipment, based on a result of the comparison between said detected response signal and said reference data;
wherein said method comprises preliminary steps ofdownloading a measuring and an authenticating algorithm from a remote server or a data base into the memory of said mobile communication equipment;
downloading said reference data from a remote server into the memory of said mobile communication equipment;
producing said response signal according to a measuring algorithm, using said authenticity captor;
authenticating said response signal by means of said mobile communication equipment, using said authenticating algorithm and said reference data, thereby producing an authentication result; and
generating an output signal representative of said authentication result.

Abstract
The present invention relates to a method and a system for the local or remote authentication of an item, in particular a security document, with the help of a authenticating device, comprised in, connected to, or linked to mobile communication equipment. Said item carries a marking exhibiting a characteristic physical behavior in response to interrogating energy, such as electromagnetic radiation and/or electric or magnetic fields. Said marking may comprise physical and logical security elements, e.g. a barcode, or a characteristic particle or flake pattern, exhibiting a characteristic physical response.
