Description
. CA 02668483 2009-05-01 Portable data carrier 100011 This invention relates to a portable data carrier. The invention relates further to a method for producing a portable data carrier.
[0002] Portable data carriers are used for example in cashless payments, in access controls, as identification documents, etc. Many applications use portable data carriers having graphical representations. Insofar as the graphical representations are security-relevant, they should be protected against tampering. The graphical representations may be for example a photograph of the owner of the portable data carrier.
[0003] From US 5,421,619 it is known to apply a strip of recording material for la-ser inscription to an identification card having a photograph of an authorized user. An image determined by processing of the photograph is inscribed by a laser beam in the recording material in proximity to the photograph.
[0004] In the known identification card the photograph and the image derived therefrom are perceived as separate graphical elements.
[0005] From DE 41 34 539 Al there is known a recording medium with colored image information. The image information is divided up into at least two information portions which are congruently superimposed and complement each other to form the total information. The information portions are applied in separate working steps. At least one of the information portions is present so as to be inaccessible from outside.
In particular, the image information is divided up into a black and white component and a color component. The black and white component is burnt into a transparent film layer of the recording medium as a grayscale image for example by a laser scriber.
In particular, the image information is divided up into a black and white component and a color component. The black and white component is burnt into a transparent film layer of the recording medium as a grayscale image for example by a laser scriber.
[0006] The congruent superimposition of the information portions is relatively elaborate and limits the design options in representing the image information.
[0007] The invention is based on the object of preventing any tampering with a graphical representation on a portable data carrier very reliably with reasonable effort.
100081 This object is achieved by the inventive portable data carrier and method of producing a portable data carrier described herein.
100091 The inventive portable data carrier has a carrier with a first graphical representation and a second graphical representation. The second graphical representation is better protected against tampering than the first graphical representation. Further, the second graphical representation is configured as a reference for detecting tampering with the first graphical representation. The inventive portable data carrier is characterized by the fact that only a partial area of the first graphical representation laterally overlaps with the second graphical representation and there is no lateral overlap between the first graphical representation and the second graphical representation outside the partial area.
100101 The invention has the advantage that the relatedness of the first and second graphical representations is well recognizable, there is good protection from tampering with the first graphical representation, and the first graphical representation can nevertheless be produced by conventional methods without any appreciable restriction in the freedom of design. Good recognizability of the first graphical representation can be guaranteed because it overlaps with the second graphical representation only in the partial area.
100111 The first graphical representation can be configured to be polychromatic.
Further, the portable data carrier can be configured in such a way that the first graphical representation is invisible in the partial area. This obtains a clear separation between the first and second graphical representations and guarantees good recognizability of the second graphical representation. Further, it is possible that the first graphical representation is configured to be transparent, partly transparent or homogeneous in the partial area. This means that account can be taken of the peculiarities of the intended application case.
10012] Preferably, the first graphical representation is produced by printing technology. This permits a high quality level with relatively low production costs.
[0013] In a preferred exemplary embodiment of the portable data carrier, the first graphical representation is configured as a photograph of the owner of the portable data carrier.
[0014] The second graphical representation can be configured as a grayscale image.
Grayscale images can be configured to be very tamper-resistant with reasonable ef-fort.
[0015] In a preferred exemplary embodiment, the second graphical representation has a smaller format than the first graphical representation. This has the advantage that only a small surface area is required for the second graphical representation, thus keeping the impairment of the first graphical representation within limits.
Another advantage consists in the fact that the effort for producing the second graphical repre-sentation is minimized. In particular, the first graphical representation can be at least twice, preferably at least three times, as big as the second graphical representation.
Furthermore, the second graphical representation can be formed partially outside the first graphical representation. This permits the impairment of the first graphical repre-sentation to be reduced further.
[0016] The second graphical representation is preferably configured as an irre-versible change in the carrier. This renders tampering with the second graphical repre-sentation nearly impossible. Further, the second graphical representation can be formed at least partially inside the carrier. This has the advantage that the access to the second graphical representation that is necessary for tampering is considerably im-peded, and it is hardly possible to tamper without visibly damaging the carrier. In par-ticular, the second graphical representation can be configured as a laser inscription.
Laser inscriptions have the advantage of being irreversible and thus very tamper-resistant and of involving a technology that is used on a large scale and is thus readily available and relatively inexpensive.
[0017] In a preferred exemplary embodiment, the second graphical representation is derived from the first graphical representation. In particular, the second graphical representation represents the same motif as the first graphical representation. This makes it possible to detect by a simple comparison of the first and second graphical representations whether the first graphical representation has been tampered with.
Further, the portable data carrier is preferably so configured that the second graphical representation is visible in the partial area. The partial area is preferably configured as a circular segment, in particular as a quadrant. This permits a placement of the second graphical representation such that the first graphical representation is only slightly influenced. It is further advantageous here when the partial area borders on the outside contour of the first graphical representation. An especially small im-pairment of the first graphical representation is normally achievable when the partial area is disposed in a corner of the first graphical representation.
100191 The portable data carrier can have a format according to the standard ISO
7810, in particular the format ID-1. Further, the portable data carrier can be config-ured in particular as an identification document, e.g., in the format ID-3.
[0020] The invention relates further to a method for producing a portable data car-rier. In the inventive method, a carrier is provided with a first graphical representation and a second graphical representation. The second graphical representation is better protected against tampering than the first graphical representation and is configured as a reference for detecting tampering with the first graphical representation.
The peculi-arity of the inventive method consists in the fact that only a partial area of the first graphical representation is configured to laterally overlap with the second graphical representation, and there is no lateral overlap between the first graphical representa-tion and the second graphical representation outside the partial area.
[00211 It is especially advantageous when the graphical information within the par-tial area of the first graphical representation is modified before the carrier is provided with the first graphical representation. In this way the partial area can be designed op-timally with respect to the second graphical representation. In particular, the first graphical representation can be configured to be transparent, partly transparent or ho-mogeneous in the partial area.
[0022] The invention will hereinafter be explained more closely by the exemplary embodiments shown in the drawing.
[0023] There are shown Fig. 1 an exemplary embodiment of a portable data carrier configured according to the invention in a schematic plan view, Fig. 2 the portable data carrier shown in Fig. 1, in a schematic sectional represen-tation, Fig. 3 a schematic representation of the image information underlying the graphic, Fig. 4 the graphic in the form in which it is applied to the carrier of the portable data carrier, and Fig. 5 a schematic representation of the image information of the control graphic.
[0024] Fig. 1 shows an exemplary embodiment of a portable data carrier 1 config-ured according to the invention in a schematic plan view. An associated schematic sectional representation is shown in Fig. 2. The portable data carrier 1 is configured for example as an identification card, a health card, a driver's license, etc., and has a card-shaped carrier 2 which is made for example of plastic material. The portable data carrier 1 can be configured according to the standard ISO 7810 and have in particular the format ID-1 or ID-3. Likewise, the portable data carrier I can be configured as a document having one sheet or a plurality of sheets and being preferably made of pa-per.
[0025] On the carrier 2 there are formed a graphic 3 and a control graphic 4, the control graphic 4 being shown by dotted lines for reasons of clarity. The graphic 3 has for example a rectangular format and can be configured in particular as a passport photo of the owner of the portable data carrier 1. Taken alone, the graphic 3 has insuf-ficient protection from tampering and is produced for example by a printing method, in particular retransfer, thermal sublimation, thermotransfer or ink jet printing. The graphic 3 can be configured to be mono- or polychromatic. As indicated by Fig.
2, the graphic 3 is disposed in particular on the surface of the carrier 2.
[0026] The control graphic 4 has a smaller format than the graphic 3 and is dis-posed partially within an overlap area 5 which is configured as a partial area of the graphic 3. Outside the overlap area 5 there is no overlap between the graphic 3 and the control graphic 4. The outside contour of the overlap area 5 is configured in particular as a quadrant. The control graphic 4 is configured so as to be largely tamper-resistant, i.e. an attempt at tampering with the control graphic 4 will lead to visible damage to the portable data carrier 1. For example, the control graphic 4 is inscribed in the car-rier 2 by a laser beam. As indicated by Fig. 2, the control graphic 4 is preferably dis-posed inside the carrier 2, so that the carrier 2 is damaged upon tampering with the control graphic 4.
[0027] The control graphic 4 serves to permit tampering with the graphic 3 to be determined. For this purpose, the control graphic 4 is so configured that there is a rela-tion between the optical information of the control graphic 4 and the optical informa-tion of the graphic 3, so that it is possible to recognize tampering with the graphic 3 by a comparison of the graphic 3 with the control graphic 4. In particular, the control graphic 4 is likewise configured as a passport photo of the owner of the portable data carrier 1. The control graphic 4 here preferably has a lower resolution than the graphic 3 and is not congruently superimposed on the graphic 3 in the overlap area 5, i.e. the image information of the graphic 3 and the image information of the control graphic 4 do not match in the overlap area 5.
[0028] The production of the portable data carrier I will hereinafter be described by Figs. 3 to 5.
100291 The portable data carrier 1 is first produced without the graphic 3 and with-out the control graphic 4. Then the graphic 3 is applied to the carrier 2 of the portable data carrier 1 in particular by printing technology.
[0030] Fig. 3 shows a schematic representation of the image information underly-ing the graphic 3. Said image information may be for example a passport photograph of the owner of the portable data carrier 1, which is rendered in Fig. 3 by a stylized representation of a face. The image information can be present in color or as a gray-scale distribution, preferably in a resolution of at least 300 DPI (dots per inch). Any image formats are in principle possible, whereby a soft frame can be provided and image enhancement measures by means of software can be used. From the image in-formation shown in Fig. 3 the graphic 3 shown in Fig. 4 is determined.
[0031] Fig. 4 shows the graphic 3 in the form in which it is applied to the carrier 2 of the portable data carrier 1. The graphic 3 has in the area of its bottom right corner the overlap area 5 which is configured as a circular segment, in particular as a quad-rant. Other geometrical forms of the overlap area 5 are likewise possible. The overlap area 5 can be configured in such a way that the image information of the graphic 3 is invisible there and instead for example a white surface is formed. Likewise, the over-lap area 5 can also be configured to be transparent or semitransparent, so that any graphical elements located therebelow are completely visible or show through.
[0032] From the image information shown in Fig. 3 the image information of the control graphic 4 is determined. The control graphic 4 preferably has a smaller format than the graphic 3. For example, the size of the control graphic 4 can correspond to one third of the size of the graphic 3. Further, the control graphic 4 is preferably rep-resented as a grayscale image with for example 256 grayscale values. It is also possi-ble to use fewer grayscale values, whereby a strictly black and white representation (two grayscale values) is only suitable to a limited extent. The image information of the control graphic 4 is shown in Fig. 5.
100081 This object is achieved by the inventive portable data carrier and method of producing a portable data carrier described herein.
100091 The inventive portable data carrier has a carrier with a first graphical representation and a second graphical representation. The second graphical representation is better protected against tampering than the first graphical representation.

The graphic 3 has in the area of its bottom right corner the overlap area 5 which is configured as a circular segment, in particular as a quad-rant. Other geometrical forms of the overlap area 5 are likewise possible. The overlap area 5 can be configured in such a way that the image information of the graphic 3 is invisible there and instead for example a white surface is formed. Likewise, the over-lap area 5 can also be configured to be transparent or semitransparent, so that any graphical elements located therebelow are completely visible or show through.
[0032] From the image information shown in Fig. 3 the image information of the control graphic 4 is determined. The control graphic 4 preferably has a smaller format than the graphic 3. For example, the size of the control graphic 4 can correspond to one third of the size of the graphic 3. Further, the control graphic 4 is preferably rep-resented as a grayscale image with for example 256 grayscale values. It is also possi-ble to use fewer grayscale values, whereby a strictly black and white representation (two grayscale values) is only suitable to a limited extent. The image information of the control graphic 4 is shown in Fig. 5.
- 8 -[0033] The image information of the control graphic 4 as shown in Fig. 5, which is again shown by dotted lines as in Fig. 1, is inscribed irreversibly in the carrier 2 of the portable data carrier 1 at least partly within the overlap area 5 of the graphic 3 by means of a laser beam. The thus produced portable data carrier 1 is shown in Fig. 1. In the exemplary embodiment of the portable data carrier 1 shown in Fig. 1, the control graphic 4 is disposed partly within and partly outside the graphic 3. The overlap area 5 is so designed here that the image information relevant for use of the graphic 3 - i.e.
for example the parts of the passport photo required for identifying the owner of the portable data carrier 1, such as the facial contour - are disposed outside the overlap area 5 and thus readily visible. This means that the use of the graphic 3 is not impaired by the control graphic 4. At the same time, the overlap between the graphic 3 and the control graphic 4 makes it clear that there a relation between the graphic 3 and the control graphic 4. Further, the spatial proximity of the graphic 3 and the control graphic 4 facilitates comparison of the graphic 3 with the control graphic 4.
[0034] In addition to the graphic 3 and the control graphic 4, the portable data car-rier 1 can have further elements which are not shown in the drawing. For example, the portable data carrier 1 can have an integrated circuit for storing and/or processing in-formation. Likewise, the portable data carrier 1 can have a magnetic stripe.
There can also be disposed on the portable data carrier I one- or multidimensional security ele-ments, such as bar codes, which are applied by printing technology or inscribed by means of a laser.
