Abrégé

The invention relates to a method for producing a sheet of tracing paper having a darkness index of less than 40 % measured in accordance with ISO 2469, in which a paper pulp based on virgin cellulose fibres in aqueous suspension is subjected to the action of a cellulase-based enzyme product for a pre-determined period of time prior to the mechanical refining thereof.

Abrégé

The present invention relates to a flat security member having a relatively small format, such as a thin board, characterised in that it comprises at least one through-hole. The invention also relates to a method for producing the same. The invention further relates to a sheet material comprising said member, and to a security document or an item to be authenticated comprising said sheet material.

Abrégé

The present invention relates to a method of reading at least one bar code (20) carried by a substrate (21), the method comprising the following steps: 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 (20), 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.

Abrégé

The invention concerns a secure article, in particular 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, in particular spatial or physical, of said at least identifying element.
