Abstract:
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.
Abstract:
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.
Abstract:
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.
Abstract:
The invention relates to a self-adhesive or heat-sealable security information medium designed to be applied to a page of a security document and to receive printing and/or writing, comprising an adhesive layer and at least one covering layer that covers the adhesive layer, characterized in that the cohesive strength of the covering layer is less than the adhesive strength of the adhesive layer.The invention also relates to a method for the security protection of a page of a security document and to a security protection feature used in the security protection method.The invention also relates to a page of a security document possessing said security protection feature and to a passport possessing said page.
Abstract:
The present invention relates to a self-adhesive or thermally bondable security document that can be affixed to an article, characterized in that it comprises at least one medium capable of receiving print on the front side, said medium having, on its reverse side, at least one self-adhesive or thermally adhesive layer and at least one marker that emits a characteristic signal by itself, such that, after the document has been bonded by means of said adhesive layer to the article, in the event of disbandment of the document at least part of said marker detaches from the medium. The invention also relates to a method of authenticating the article.
Abstract:
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 fibers 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 fibers, with preferably a lower proportion of long natural fibers relative to short ones when the fibrous mass includes synthetic fibers, in particular between 5 and 25% of synthetic fibers.
Abstract:
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.
Abstract:
A secure article, notably a security and/or valuable document, comprising at least one substrate, at least one visible authenticating structure, at least one inspection zone defined at least partly by the authenticating structure, the authenticating structure delimiting at least partly the outline of the inspection zone and/or serving to locate the inspection zone, in the inspection zone at least one identifying element different from the authenticating structure, the inspection zone enabling an identification information to be supplied with at least one feature, notably spatial or physical, of the identifying element.
Abstract:
The invention relates to an assembly including an article to be authenticated, an authentication composition and a member for applying the composition, capable of retaining said composition by capillarity, wherein the article to be identified contains a first reagent selected from nickel, copper, cobalt or iron derivatives, or from dithiooxamide or oxime derivatives capable of reacting with a second reagent of the authentication composition selected respectively from among dithioxmide or oxmime derivatives or from nickel, copper, cobalt or iron derivatives, so as to form a visible and permanent coloured mark.
Abstract:
The invention concerns a secure article, notably a security and/or valuable document (1), comprising: at least one substrate, at least one visible authenticating structure (4; 11; 22; 32; 42; 51), at least one inspection zone (5) defined at least partly by the authenticating structure, the authenticating structure delimiting at least partly the outline of the inspection zone and/or serving to locate the inspection zone, in the inspection zone (5), at least one identifying element (3, 50, 61) different from the authenticating structure, the inspection zone enabling an identification information to be supplied with at least one feature, notably spatial or physical, of said at least identifying element.
