Definitions

• the present invention relates to an identification card according to the preamble of Claim 1.
• An identification card of this type is known from US 4892336, which describes an identification document provided with a cylinder lens structure, in the focal point of which there is provided a pattern of lines* wherein tilting allows ever-different lines to be perceived.
• the prior art discloses a large number of security means against the alteration of photos, imprints and the like. There are various levels of security. After all, some data is more important than other data and therefore has to be protected more effectively.
• the term “front” refers to the side including, in particular, data allowing identification of the person in question, such as a photo of the holder of the identification card and biometric characteristics such as height and the like.
• the card may, of course, contain chips in order locally to check various factors.
• top refers, in the present description, to the portion located closest to the observer.
• US 4765656 discloses a bank card having a cylinder lens structure, wherein the above-described projecting effect of an image is obtained by tilting.
• the object of the present invention is to provide a further security means for an identification card. More particularly, this security means is to be such that, on the one hand, variable data, i.e. data which is dependent on the legitimate holder of the card, may easily be attached at the location of the security means and, on the other hand, it is immediately clear if the individually input data has been tampered with.
• the position of the relevant data is not altered.
• the intensity may change as a function of the angle at which the relevant information is observed.
• a moir ⁇ pattern is used in combination with the writable information. Because this individual input information does not meet the requirements met by a pattern providing a moire pattern, the user will immediately notice, on tilting the relevant portion of an identification card, the occurrence of the moire effect of the pattern present at all times during the substantial non-alteration of the position of the individually attached information.
• the above-described moire effect may be obtained in any manner known per se from the prior art.
• the moir ⁇ effect is produced in a particularly simple manner in that a line pattern is attached below the lenses.
• Lines of this type are preferably parallel and extend, in particular, at a low angle with respect to the longitudinal axis of the lenses, which are preferably configured as cylinder lenses.
• This angle is, more particularly, an angle which is between 2 and 6° with respect to the longitudinal centre line of the cylinder lenses and is, more particularly, approximately 3°.
• the frequency of the lines i.e. the distance between the lines, is preferably at most the diameter of the relevant cylinder lenses. If this distance is smaller, the pattern of the lines is preferably such that a fixed number of lines fits within the diameter of the lens. Instead of lines, parts of lines (strips), points or a "grid" pattern may also be used in combination with the lenses. It will be understood that the lenses may also be configured as lenses other than cylinder lenses.
• the line pattern or other pattern is preferably located above or next to the written information.
• This written information may be provided with a laser light-sensitive layer.
• a laser-light sensitive layer include a polycarbonate layer having a very low carbon content. Laser light striking the carbon results in the formation of heat, which leads to carbonisation of polycarbonate and resultant blackening.
• the staggered pattern is located in the focal point/focal line of the relevant cylinder lens.
• the relevant information is preferably not located on the focal point or the focal line but may be attached, viewed from the outside, both before and after the projecting pattern.
• the staggered pattern is, in particular, attached in the form of any printed pattern known in the prior art.
• the non-staggering information which is preferably not in focus with the lens, is preferably attached at a later stage and, more particularly, in the above-described mariner using a laser beam.
• a reddish/red colour will preferably be used in combination with lenses for the lines, points and the like used to obtain a moire pattern.
• Figure 1 shows the front of a driving licence
• Figure 2 shows the back of a driving licence according to Figure 2;
• Figure 3 is a cross section along the line EQ-III in Figure 2; and Figure 4 is a plan view of the lines of the moir ⁇ pattern;
• Figure 5 shows the moire pattern produced on tilting of the portion of the driving licence which is configured in accordance with the invention.
• Figures 1 and 2 show a driving licence 1.
• JhejEront is denoted by 2 and the back, illustrated in Figure 2, by 3.
• the front includes data relating to the holder such as a photo 7 and also a description of personal characteristics of the holder.
• the back indicates the categories for which the user is qualified. Additional data may be provided.
• the security means shown in Figures 2 to 4 is, according to the present invention, proposed.
• These means consists of a lens structure 9.
• the lenses 9 are elongate cylinder lenses having a diameter a. These lenses may be made from any known transparent material such as, for example, a polycarbonate material.
• This layer 10 consists of a laser- writable layer. On its top, the layer 10 is provided with an imprinted pattern. In the present. example, this pattern consists of a large number of parallel lines 11 extending at a small angle to the longitudinal axis 16 of the cylinder lenses ( Figure 4). In the illustrative embodiment shown, this small angle is approximately 3°.
• the lines 11, which are provided by the printer (before the attachment of the lenses 9), are red/reddish in colour and transparent to (black) information located therebelow. The distance between the lines is denoted by b.
• a nxb, wherein n is an integer.
• Information may be written in the layer 10 with the schematically illustrated laser beam 5. This information is attached in the layer 10 itself and is located below the imprinted lines 11. Because these lines are (partially) transparent, this does not impede the legibility of the information 12.
