Definitions

  • the present disclosure is directed towards a security sheet, a security document comprising such a security sheet and a method of manufacturing such a security sheet or document.
  • Security documents and booklets such as passports, passbooks, identification documents, certificates, licences, cheque books and the like, commonly include a security sheet comprising a data sheet.
  • a passport booklet typically comprises a cover, a plurality of internal visa pages and at least one data sheet displaying the personal data of the passport holder.
  • the visa pages are made from paper and are sewn together along a stitch line coincident with the fold of the document.
  • the data sheet may be formed from a plastic, typically polycarbonate, and during its manufacture a number of thin plastic layers are laid over one another and laminated together, thereby forming a thicker plastic body. As this plastic body is typically rigid it is not directly attached at the stitch line or otherwise the booklet may not be able to bend effectively about the fold.
  • the security sheet may comprise a flexible hinge or attachment layer embedded in and extending from the plastic body of the data sheet and the data sheet is attached about the fold using the flexible hinge.
  • a flexible hinge or attachment layer embedded in and extending from the plastic body of the data sheet and the data sheet is attached about the fold using the flexible hinge.
  • fraudsters may attempt to manipulate the security document by separating the data sheet and flexible hinge along the interface therebetween and replacing the data sheet with one containing fraudulent personal data.
  • An object of the present disclosure includes increasing the difficulty of fraudulently dismantling a security sheet by separating a data sheet from an attachment layer.
  • a further object of the present disclosure includes improving the identification by inspection officers of any such dismantling in a fraudulent security document. Further objects include providing an improved method of manufacture of such a security sheet and a security document comprising such a security sheet.
  • the present disclosure therefore provides a security sheet, security document and method in accordance the claims.
  • the term "nonlinear" means that an edge profile is not straight and comprises at least one curve and/or at least two straight lines at a non-straight angle to one another.
  • a fraudster is unable to effectively separate the data sheet from the attachment layer by cutting along a straight line and parallel to an outer edge and/or fold line of the security sheet.
  • cutting a straight line and parallel to the outer edge and/or fold line which is the most common and easiest method of separating the data sheet from the rest of the security sheet, they can only cut through both the attachment layer and data sheet, through only the data sheet or through only the attachment layer.
  • the removed data sheet will always be attached to part of the attachment layer and/or vice-versa. It is much harder for a fraudster to replace the data sheet with one containing fraudulent personal data because they will always have to replicate at least part of the data sheet and attachment layer. Due to the increased likelihood of poor replications, fraudulent alterations are therefore also easier to identify.
  • edge profile refers to the shape or outline of an edge when an outer surface extending from the edge is viewed in plan view.

  • at least one inner and/or proximal edge section comprises: at least one of a tooth, sinusoid, castellation (e.g. a rectangular or square tooth) and/or triangular tooth.
