A method for integrating a hologram into the body of a security document that has a laminated body. The method includes: providing a holographic film having a backing substrate layer and a photo layer; providing additional substrate layers; carrying out a laminating process in order to form the laminated body, the holographic film together with the additional substrate layers being collated to form a substrate layer stack and being combined, together with the additional substrate layers, in a high-pressure, high-temperature laminating method to form the laminated body. There is also described a corresponding security document body.

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for applying a ghost image to an identification document that include the actions of obtaining a first image of an object. Identifying a first portion of the first image that corresponds with the object and a second portion of the first image that does not correspond with the object. Generating a second image by converting the first image to a negative image, and removing the second portion of the first image that does not correspond to the object. Generating a halftone image from the second image. Causing optically variable media to be applied to the identification document based on the halftone image. The optically variable media has a first appearance when viewed from in reflected light at a first angle and a second, different appearance when viewed in reflected light at a second, different angle.

A laminate includes: a first laminate member; a second laminate member; and a hidden print formed by printing invisible ink between the first laminate member and the second laminate member. The hidden print is configured to absorb electromagnetic radiation outside the visible range. When irradiated with electromagnetic radiation outside a visible range that has passed through at least one of the first laminate member and the second laminate member, the hidden print absorbs the electromagnetic radiation to thereby show a sign, and, when irradiated with visible light, the hidden print does not show the sign.

Processor, apparatus, and method for reordering a stream of memory access requests to establish locality are described herein. One embodiment of a method includes: storing in a request queue memory access requests generated by a plurality of execution units, the memory access requests comprising a first request to access a first memory page in a memory and a second request to access a second memory page in the memory; maintaining a list of unique memory pages, each unique memory page associated with one or more memory access requests stored the request queue and is to be accessed by the one or more memory access requests; selecting a current memory page from the list of unique memory pages; and dispatching from the request queue to the memory, all memory access requests associated with the current memory page before any other memory access request in the request queue is dispatched.

A method of manufacturing a security document, including: providing a polymer substrate having first and second surfaces; and: applying an array of focussing elements to the first surface of the polymer substrate across a first region; forming an image array by: providing a die form having a surface including an arrangement of raised areas and recessed areas defining the pattern; applying a first curable material to the surface of the die form so it substantially fills the recessed areas; bringing a pattern support layer in contact with the surface of the die form so it covers the recessed areas; separating the pattern support layer from the surface of the die form so the first curable material in the recessed areas is removed from the recessed areas and retained on the pattern support layer; and at least partly curing the first curable material in one or more curing steps.

A display member includes: a surface which is an observation object; a first image pattern which is covered by the surface and displays, through the surface, a first image including one or more first information elements for identifying an owner of the display member; a second image pattern which is covered by the surface and in which one or more second information elements are embedded, a part of the second image pattern restricting identification of the one or more second information elements, the second image pattern including a second image that differs from the first image and is for identifying the owner of the display member; and a concealment pattern that is located between the second image pattern and the surface and removes the restriction on identification of the one or more second information elements by concealing the part of the second image pattern.

Into a plastic card (1) of polycarbonate layers (10; 11; 12) there is laminated a security thread (3) by applying pressure and temperature, the security thread itself having a carrier foil (5) of polycarbonate and a coating (6) that is borne by the carrier foil and conveys holographic information. The connection of the polycarbonate carrier foil (5) of the security thread with the polycarbonate layer (10; 11; 12) of the data carrier adjoining said carrier foil takes place without using an adhesive or primer.

A security device is disclosed, comprising an array of focussing elements with regular periodicity in at least a first direction, each focusing element having an optical footprint of which different portions will be directed to the viewer in dependence on the viewing angle; and an array of image elements with regular periodicity in at least the first direction overlapping the array of focusing structures, the image elements representing portions of at least two respective images, and at least one image element from each respective image being located in the optical footprint of each focusing structure. The security device includes a first region and a second region which is laterally offset from the first, the image elements in the first region being laterally shifted in at least the first direction relative to the image elements in the second region such that, at a first viewing angle, in the first region of the device the focussing structures direct image elements corresponding to a first image to the viewer such that the first image is displayed across the first region of the device, and simultaneously, in the second region of the device, the focussing structures direct image elements corresponding to a second image to the viewer such that the second image is displayed across the second region of the device, and at a second viewing angle the second image is displayed across the first region of the device and simultaneously the first image is displayed across the second region of the device. The security device further comprises a colour filter located in use between the image elements and the viewer, the colour filter overlapping at least part of the array of focussing elements and the array of image elements, and having a first colour in the first region of the device and a different colour in the second region of the device such that the colour appearance of the first and second images is different in the respective first and second regions of the device.
