Abstract: Provided is a method for securing a security document comprising at least personal data pages and a cover sheet placed outside the personal data pages, the method comprising, during security document manufacturing, a step of stitching the personal data pages and the cover sheet together by means of an upper thread and a lower thread interlaced together and a step of treating at least a part of the stitching with ultrasonic welding so as to structurally modify the thread.

Abstract: An information page (1) of a security document, includes: an information part (3), on the upper or lower surface of which part of the information recorded on the information page (1) can be seen; and a flexible connecting part (2) with good bending strength for attaching the information page (1) to a security document. To ensure that detaching the information part and the connecting part from each other leaves visible marks, the connecting part (2) has a netlike structure, and the connecting part (2) is arranged to penetrate into the information part (3) in the immediate vicinity of the upper or lower surface of the information part.

Abstract: An information page (1) and method are provided for a security document. The information page includes: an information part (3), and an attachment part (2) for attaching the information part to the security document. In order to make forgery visually detectable, the information part (3) is provided with a unique identifier (5), and the attachment part (2, 2?) is provided with the same unique identifier (5) as the information part (3).

Abstract: The invention relates to a smartcard (1) comprising: a first section (4) enclosing a contactless microcircuit (2). In order to improve the security of the smart card against forgery said smartcard comprises: a compensation section (7) of a transparent material, said compensation section having substantially the same thickness as the first section (4) and surrounding said first section, a top section (5) of a transparent material, said top section being arranged on top of said first section (4) and said compensation section (7) as a surface layer of said smartcard (1), and a bottom section (6) of a transparent material, said bottom section being arranged under said first section (4) and said compensation section (7) as a surface layer of said smartcard (1).
