Definitions

  • the present invention relates to: a method for ensuring the traceability of copy acts on information carriers in which useful information is subordinated to an identification which is essentially inseparable from it, - Method for providing identification over an area of an information carrier for useful information, such as for a securing method of the type mentioned above, a set of information carriers or subsets of information carriers, each carrier having an area for receiving useful information and, over a substantial part of the area, identification identification being provided on the carrier, Information carriers with an identification distributed over at least one writable surface area, as part of the sentence just mentioned, - a copy-protected paper sheet.
  • the present invention now has the following problem:
  • the present invention is based on a securing method of the type mentioned at the outset and solves it in accordance with the wording of the characterizing part of claim 1.
  • the identification for each recipient is chosen differently when distributing carriers with identical useful information to the recipient, it is easily possible to determine from a copy with the useful information and the identification, thanks to the identification, who the copying and in particular the illegally copying body was.
  • the wording of claim 2 is followed. If the identification is provided in such a way that it is more difficult to interpret when the carrier is copied than the useful information, i.e. in contrast to the proposal according to claim 2, then by copying and copying the copy, etc., hereinafter referred to as copying, it can finally be achieved that the useful information can still be interpreted, but no longer the identification, which makes it impossible to find the illegally copying entity.
  • the carrier is designed, for example, to record visual information contrasts, for example a paper sheet to be described, then it is further proposed to proceed according to the wording of claim 3.
  • the word "subordinate" is to be understood in the sense that the distributed identification appears on the carrier in such a way that the useful information provided on the carrier remains interpretable, for example remains legible without too much effort.
  • the same procedure is also used in general a carrier for other types of information, such as a magnetic tape, proposed.
  • information carriers in particular paper sheets, are known, for example according to CH-PS 645 308 or also DE-OS 33 25 116, in which useful information is subordinated to an identification which is essentially inseparable from it.
  • DE-OS With such carriers, in particular those according to the aforementioned DE-OS, it is possible at any time and precisely to make this identification recognizable at any time and by anyone.
  • a method for providing is provided in close reference to the above-mentioned method for providing identification by means of symbols which are provided randomly distributed in the area and from which the symbols defining the identification are practically "filtered" by means of a masking technique an identification is proposed, in which features of the identification in the entire area Art can be provided, but a sub-area not known to the user is defined, in which the predetermined features that define the identification are provided.
  • this procedure is also ideal for use on carriers for the first-mentioned procedure to ensure the traceability of copy acts.
  • the invention further proposes to proceed according to the wording of claim 8.
  • the identification marking is applied across the useful information font, by local thickening or thinning of the font lines, the above-mentioned requirement is ensured: Either only the thickening of the typeface that defines the identification features occurs during continued copying come to light, or white spots appear at the dilution points, which in turn define the identification until the useful information has also disappeared.
  • the procedure according to claim 8 for font information can also be implemented by deliberately changing letter shapes, spacings, etc. Such changes, barely recognizable to the reader of the information, can make identification clearly recognizable.
  • These methods on an information carrier are particularly suitable for carriers for visual contrast information, such as for paper sheets, on which information is drawn or written.
  • the above-mentioned method can also be used for other carriers: for example, magnetic tapes for analog or digital information recordings can easily be provided with "noise" identifying the specimen on the same carrier area to which the said analog or digital information is applied In such a way that reading the applied information is not disturbed or is only slightly disturbed. It should be emphasized that in the case of carriers to be protected in this way, le only the interpretation of the information must be ensured. In view of the classified speech information and the importance of this classification, it is immaterial whether a speech-frequency noise is additionally audible or temporarily audible in the case of a speech signal on tape.
  • Preferred embodiment variants of such a set are specified in claims 12 to 18, wherein according to claims 13 to 16 and 18 the configuration of the information carriers specified there for the set is also suitable per se for other uses for the information carriers.
  • an information carrier such as a sheet of paper, a magnetic tape, a computer diskette, on which information, such as writing, analog or digital signals, is recorded in an area 3, corresponding to the carrier type.
  • a carrier 1 with the area 3 for information recording usually has a predetermined identification area 5, in which a copy identification is entered for important information before the carrier 1 is distributed as carrier copies 1a and 1b to users A, B etc. 1, copy 1a is provided with the identification note A1001, for example, copy 1b with the identification note A1020 at the issuing point, prior to distribution.
  • an identification mark 5a or 5b is distributed over at least a substantial part of the respective area 3 such that removal, such as separation, or covering of this identification mark 5a or 5b is not possible when the information contained in the area 3 is copied.
  • the identification features A1001 are provided in the area 3 on the copy delivered to the receiver A, and the identification features A1020 are provided in the area 3 sent to the item B in the corresponding area 3.
  • the mentioned identification marks are distributed over the corresponding areas 3. The publisher of these distributed copies 1a, 1b knows the respective identification.
  • This procedure according to the invention can in principle be used for all data carriers to be protected against copying in the abovementioned sense.
  • data carriers e.g. magnetic tapes, floppy disks, document sheets, etc.
  • the identification marking is inseparable from information applied to the carrier in the same carrier region and is also of the same type, i.e. for example, in the case of an analog stored signal, there is also an analog stored signal, so that when such a carrier is copied, the identification identifier cannot be separated from the information here, as could be done electronically by filtering, for example.
  • the identification marking of the information must be subordinate so that the clear interpretation of the information remains possible when it is read out.
  • 3a to d show four possible variants of how identification identification, shown here, for example, as an alphanumeric symbol A, is preferably provided on such a sheet.
  • the sheet shown here only in sections is covered with a full-coverage print pattern, as shown, preferably a line pattern 7.
  • a pattern of parallel, straight lines is primarily shown. This is for the sake of simplification.
  • the pattern is preferably a meander line pattern as shown in FIG. 3a above at 7a.
  • the identification marks or symbols 9 are applied to a sheet patterned in this way by locally changing the pattern.
  • the identification letter A shown for example, is applied by locally thickening the line pattern 7.
  • the identification symbol 9b again for example an A, is applied by local interruptions or reduction of the line pattern contrast.
  • the identification feature 9c is applied by locally changing the line course of the pattern 7, while according to FIG. 3d the identification feature 9d is applied by locally displacing the line pattern.
  • the letter sequence A - F is used to represent, for example, font information 10 applied to the paper sheet, and it is evident, even with this simplified interpretation for the sake of illustration, how the identification indicators 9 are visually subordinate to the information 10 applied.
  • the identification mark 9 In order to prevent that when copying such a carrier, as shown for example in Fig. 3, then when copying the copy etc., i.e. When the wearer replicates, with which the contrast of the line pattern and the contrast of the information 10 disappears more and more, the identification mark 9 cannot be interpreted earlier than the information, the identification mark 9 must be designed such that the latter remains interpretable at least as long as the information 10, which is easily possible by appropriate design, in particular in the manner shown in Fig. 3a, b, c and d.
  • FIG. 4 Another possibility of fulfilling this last-mentioned requirement is shown in FIG. 4.
  • An information lettering 12 is provided here in area 3.
  • the identification marking is superimposed on this lettering 12.
  • the parts 14 which are slightly contrast-enhanced when the above-mentioned copying is practically left alone on the copy, and, as shown in dashed lines, the identification of these remaining copied parts 14b can be reconstructed at any time, even if when copying said information lettering 12 or another recording has already disappeared.
  • a local contrast reduction can also be used.
  • CH-PS 645 308 for other purposes can also be used according to the invention which is intended to make information on a sheet of paper, in addition to the information contrast, only visible when electrographically copied.
  • the procedure is analogous to that of FIG. 3, however, for example, a guilloche pattern is additionally printed on the area, in a color which is outside the reproducibility of electrographic copying machines and which thus practically acts as a visual camouflage of the intended identification marks according to the present invention.
  • a guilloche pattern is additionally printed on the area, in a color which is outside the reproducibility of electrographic copying machines and which thus practically acts as a visual camouflage of the intended identification marks according to the present invention.
  • FIG. 5 shows an entire region 3 of a sheet which acts as an information carrier according to the invention.
  • the area 3 is divided into several sub-areas 15, which are covered, for example alternately, with different patterns 7 according to FIG. 3.
  • the procedure is preferably such that nowhere does a pattern of one sub-area adjoin an identical pattern of another sub-area. This is achieved in the sub-area pattern shown in FIG. 5, for example, in that the line pattern runs vertically in one sub-area 15, horizontally in the other, and a sub-area 15 is only immediately adjacent to two further sub-areas 15.
  • the identification label 9 for example in the form of symbols, such as alphanumeric, applied.
  • different orientations or techniques according to FIG. 3 can be used in a sub-area 15 considered, with respect to the pattern provided, for applying these identifiers 9.
  • the different orientation of the identification features 9 shown in FIG. 5 in a sub-area and with respect to the line pattern 15 provided there, for example, results in increased certainty that when copying, depending on the copying method selected, one or the other display technology of the identification features remains interpretable longer than the ( Information not shown here on the area 3.
  • identification marks 9 can even be used in each of the sub-areas 15, which further increases the security mentioned, namely at least in a substantial part during the aforementioned copying of area 3, if possible, the identification marks remain interpretable even longer than the information applied to area 3.
  • the procedure can be as shown schematically in FIG. 6.
  • a number of identifiers 17 are provided on the area 3 using the technique illustrated, for example, with reference to FIG. 3. Of this number of indicators 17, however, only certain form the ID.
  • the publisher of the copies to be protected knows which of the intended identifiers 17 and, if need be, in which order form the identification by, as shown schematically in FIG. 6, the x / y with respect to a reference point P of area 3 of the publisher -Coordinates each identification symbol with their order. He therefore knows the localization variables given in brackets in FIG. 6, so that, following this example, the identification AC5 can be clearly determined from the large number of symbols 17 provided.
