Abstract: The present disclosure is directed towards a security sheet (10) for displaying personal data (11) comprising a plastic substrate (12) comprising first and second outer surfaces (13, 14). A first opaque region (21) extends partially across the plastic substrate (12) between the first and second outer surfaces (13, 14). A first window (50) is at least partially surrounded by the first opaque region (21). A security device (51) comprises a transparent first device region (52) and a second device region (53) formed from a second device insert (55). The first and second device regions (52, 53) have different optical detection characteristics. The security device (51) is arranged in the plastic substrate (12) such that, when viewed in reflected light incident upon the first outer surface (13), at least part of the first device region (52) is visible at least partially around the second device region (53) in the first window (50).

Abstract: The present invention relates to a method of manufacturing a security sheet comprising a security element (11), a core structure (10) for forming the security sheet, a stack (29) including such a core structure (10), a security sheet comprising the core structure (10) or stack (29) and a security document comprising the security sheet. At least one perforation (20) is formed through, from a first core surface (13) to a second core surface (14) of, at least one core layer (12) comprising plastic. A security element (11) is fed through the at least one perforation (20) such that the security element (11) extends through, from the first core surface (13) to the second core surface (14) of, the at least one core layer (12). At least one first region (17) of the security element (11) is located over part of the first core surface (13) and at least one second region (18) of the security element (11) is located over part of the second core surface (14).

Abstract: Provided is an apparatus that includes a processing unit configured to monitor a quality of user performance in selecting one or more selectable items that are presented on a display. The processing unit is further configured to cause the one or more selectable items to be presented on the display in a modified arrangement based at least in part on the quality of user performance in respectively selecting the one or more selectable items. For example, the processing unit can be configured to cause the selectable items to be presented in a modified arrangement based at least in part on noted frequency of user error in respectively selecting the selectable items and/or on noted rate of user selection in respectively selecting the selectable items. Also provided are corresponding methods and computer program products.
