Definitions
- the invention relates to a method for verifying the authenticity of a security document as well as to a security document having perforations of elongate cross section.
- Fine perforations have been used successfully as a security feature for security documents, i.e. for documents the authenticity of which can be verified in a reasonably reliable manner, such as bank notes, passports or parts thereof, checks, etc.
- WO 97/18092 describes a security document having a pattern of fine perforations that are visible when viewed in transmission while they are invisible when viewed in reflection. Even though this feature has found to be a very reliable means for authenticating the document, it is desired to increase the uniqueness of these and similar perforations in order to provide an even higher degree of recognizability and reliability.
- WO 00/43216 teaches, inter alia, to add perforations that extend obliquely through the document and that must be viewed under a given angle.
- manufacturing such oblique perforations is difficult and their quality is likely to degrade over time, in particular when used for paper or thin plastic sheet documents that are subjected to frequent mechanical stress, such as bank notes .
- the invention uses an effect that is observed with perforations having an elongate cross section.
- the transmission characteristics depend on the orientation of the viewing direction in respect to the directions of smallest and largest diameter of the cross section of the perforations.
- viewing the document from an direction as described above allows to determine the authenticity of the documents from the observed optical trans- mission of the perforations, e.g. by comparing the observed optical transmission to an expected optical transmission and rejecting the document as invalid if there is no match.
- both these viewing directions are preferred viewing directions for a verification.
- both viewing directions are used.
- the document comprises several perfora- tions with different cross sections, a single view along the viewing direction allows to observe differently oriented perforations with different expected optical transmission values, which further increases the reliability of the verification.
- the minimum diameter of the elongate perforations should sub- stantially be equal to or smaller than the thickness of the document carrier .
- Fig. 1 shows a bank note having a security perforation pattern
- Fig. 2 shows the security perforation pattern in close view
- Fig. 3 shows a detail of the perforation pattern of Fig. 2
- Fig. 4 is a sectional view of the perforations of Fig. 3
- Fig. 5 is a detail of a second possible perforation pattern
- Fig. 6 is a detail of a third perforation pattern .
- Fig. 1 shows a bank note having a carrier 1 of paper or plastic with conventional graphical and textual elements 2, 3, 4 and a security perforation pattern 5.
- security perforation pattern 5 comprises a plurality of perforations (holes) 5a, 5b extending through carrier 1.
- the perforations are arranged in a two-dimensional array. Preferably, they extend through the whole of carrier 1, but they may also extend only partially therethrough as long as the optical transmission when viewed from a viewing direction perpendicular to the surface of carrier 1 is much larger at a perforation than at unperforated locations.
- Fig. 2 which is a close- up of perforation pattern 5 two different types of holes are used.
- each hole 5a, 5b has elongate cross section and extends through carrier 1 in a direction perpendicular to the surface la of the same.
- the cross section is preferably substantially uniform through the carrier.
- the cross sections of holes 5a and 5b in the embodiment of Figs. 3 and 4 are of equal elongate shape, but rotated in respect to each other by an angle of 90° .
- Each hole is of roughly ellipsoidal cross section having a minimum diameter dl and dl ' and a maximum diameter d2 and d2 ' , respectively.
- the minimum diameter dl of hole 5a is substantially parallel to the maximum diameter d2 ' of hole 5b and vice versa.
- the minimum diameter dl and dl ' is preferably smaller or approximately equal to the thickness D of carrier 1 and may be in the range of 50 ⁇ to 300 ⁇ m for a bank note, preferably not more than 150 ⁇ m.
- the maximum diameter may be substantially larger, e.g. at least 1.5 times larger than the minimum diameter.
- the areas of the cross sections of the holes 5a, 5b are preferably equal. In that case, when the docu- ment is viewed against a light source in optical transmission from a viewing direction 7 that is perpendicular to surface la of carrier 1, the transmission of both types of holes is the same and the holes appear equally bright. However, when viewing from a viewing direction 7' that is not perpendicular to surface la, the amount light transmitted through the different types of holes 5a, 5b will generally be different because part of the light will be blocked be the walls of the holes. For example, when viewing the document from direction 7' of Fig. 4, around 50% of the maximum amount of light will be transmitted through hole 5a while hole 5b will appear to be substantially blocked.
- a high transmission will be observed when viewing the perforation pattern along a viewing direction that is perpendicular to the direction ml of minimum diameter dl while a low transmission will be observed if the viewing direction is perpendicular to the direction m2 of maximum diameter d2.
- This effect can be used for verifying the authenticity of the document by viewing it from at least one viewing direction that is non-perpendicular to sur- face la.
- the observed optical transmission of the perforations can e.g. be compared to an expected optical transmission from this viewing direction.
- carrier 1 with two types of perfora- tions having differing cross sections, as shown in e.g. in Figs . 3 , 5 or 6.
- the perforations of the two groups will generally have differing optical transmission, which allows to check the feature by visually comparing the transmissions.
- the two types of holes 5a, 5b have cross sections that are mutually rotated by 90°.
- the holes have cross sections of different shape.
- the areas of the cross sections of the different types of points are substantially equal such that the perforations have substantially uniform optical transmis- sion when viewed along a viewing direction perpendicular to surface la. an example of two holes of such a perforation is shown in Fig. 5.
- the perforation pattern is to be inspected by a human, it is preferred to arrange the types of holes to form a human-recognizable pattern, such as the cross of Fig. 2.
- the perforations of perforation pattern 5 are preferably manufactured by laser pulses.
- the beam from the laser can either be moved while applying the pulse or several separate pulses may be applied side by side in spatially overlapping manner.
- the production of the perforation pattern is easiest when the dimension of all points is only varied in a single direction because this allows to use a single beam deflector to be operated during hole generation. This leads to a pattern where the minimum diameters of all holes are equal and parallel to each other.
- the first type of holes 5a has a minimum diameter dl that is equal to both diameters dl ' of the second type of holes 5b.
- mechanically manufactured perforations have rougher edges and therefore increased light scattering as compared to perforations generated by laser light.
- the minimum diameter dl, dl' of the holes should preferably be 150 ⁇ m or less.
- the perforation pattern 5 was used in a banknote, but it may be used in other similar applications, such as in cheques or in the pages of a passport or other document that should be hard to forge.
- Carrier 1 is preferably paper or a flexible plastic .
