摘要:
A method for authenticating and/or identifying a security and/or valuable document comprising a sheet material, wherein the sheet material can be physically altered and comprises a substrate, at least one interlaced thread structure at least partially embedded in the substrates, the method comprising the following steps: mechanically altering the sheet material so as to expose a portion at least of the interlaced thread structure, and deducing the authenticity and/or identity of the document at least by observing the exposed portion of the interlaced thread structure.

A laminated structure for an E-document, comprising a first support layer defining at least two flat flaps connected by at least one fold line, the first flap supporting an antenna and a microcircuit device enabling contactless data exchange, the second flap supporting an electromagnetic interference element arranged in relation to the microcircuit device so as to be able to oppose contactless reading and/or writing of the microcircuit device in at least one folded configuration of the structure, the structure having at least one heat-activated or pressure-sensitive adhesive layer making it possible to receive the microcircuit device and/or the antenna and/or the electromagnetic interference element at least in part in its thickness, and/or the flaps having at least one layer of an adhesive and/or a fibrous layer and/or a polymer layer having a different thickness for each of the flaps.

An assembly includes a wire antenna including at least on conductive turn, a first fibrous substrate on which the antenna extend. The first substrate comprises at least one coated paper including a fibrous base containing at least 30 mass % of natural fibres in the fibrous mass. The antenna is connected to a face of the flexible substrate. The paper includes on that face at least one surface layer containing at least one mineral load and a coating binder. The fibrous base may contain at least 40 mass %, preferably 50 mass %, more preferably 60 mass % and ideally at least 70 mass % of natural fibres, with preferably a lower proportion of long natural fibres relative to short ones when the fibrous mass includes synthetic fibres, in particular between 5 and 25% of synthetic fibres.
摘要:
A method of reading at least one bar code carried by a substrate, the method including: a) generating, especially in an automatic manner, when presenting the bar code to a system for reading the bar code, at least one authentication cue related to an intrinsic physical characteristic of the substrate and independent of the data contained in the bar code, and b) allowing the reading of the bar code, only in the event of a positive authentication of the substrate or reading the bar code regardless of the result of the authentication of the substrate and in the event of negative authentication of the substrate, preventing access to just one part of the data contained in the bar code and/or to any data that may be associated with the bar code, and which is stored on a separate data medium from the substrate.
摘要:
The present invention relates to a security document, useful in particular for preventing falsification and counterfeiting of payment vouchers or official documents by reproduction, characterized in that it includes, as security means, a security protection feature (M) consisting of a first feature (M1) formed from substances exhibiting an interferential effect and of a second feature (M2) formed from substances that react to certain stimulations, such as light radiation or thermal, magnetic, electromagnetic, electrical or microwave-type stimulation, giving a light response visible to the human eye or a specific signal detectable by means of a suitable apparatus.The invention also relates to the method of producing said document.
摘要:
The present invention relates to a structure (1) for use in fabricating a security document or a document of value, the structure comprising: an electronic device (8); an inset layer (2) made at least in part out of fiber, and including a window (4) within which the electronic device (8) extends, at least in part; and an adhesive layer (6) in contact with the inset layer.

摘要:
The present invention relates to a laser-markable substrate, comprising at least one material capable of forming a colored mark under laser irradiation and at least one tamper-proof agent producing an irreversible visible coloration when an attempt is made to chemically erase the mark.
摘要:
A structure including at least two separate integrated microcircuit devices with contactless communication, each including at least one chip and at least one antenna, said at least two integrated microcircuit devices being placed in or on the structure such that any simultaneous reading of more than one of the integrated microcircuit devices by an external reader is impossible in at least one position of the structure relative to the external reader.
摘要:
A document including an integrated microcircuit device, in particular an RFID device, the document including at least one detector configured to detect a change in at least one physicochemical magnitude, which detection is capable of being performed away from the read field of an external reader capable of obtaining at least some information relating to said change from the integrated microcircuit device, the integrated microcircuit device being configured, during communication with the external reader to inform it that there has been an attempt at attacking the physical integrity of the document as a result of detecting a corresponding change of said at least one physicochemical magnitude.
