Definitions
- the invention relates to a method for producing a data carrier according to the preamble of claim 1 and to a data carrier produced in particular according to the method according to the preamble of claim 11.
- the above data carriers are value or security documents, in particular identity cards or credit cards, which, in addition to general information, contain individual information such as user name, user portrait, serial number or the like person-specific, card-specific or document-specific
- This individual or specific information is preferably the subject of counterfeiting and manipulation and must be secured accordingly.
- a data carrier with at least one individual piece of information comprising a serial number consisting of a first part and a second part.
- the first part and the second part of the serial number can have a different color and are thus on the
- the invention is therefore based on the object of providing a method for producing a data carrier and a data carrier which has improved protection against forgery or manipulation.
- a central idea of the method according to the invention is that a first piece of information that is individual
- Information represents how the name of the authorized user of the data carrier is encrypted using an algorithm and the result of the encryption is stored on the data carrier.
- the result of the encryption represents additional information that cannot be decrypted by the general public. Only authorized persons who have the algorithm are able to decrypt the additional information and determine from the additional information whether forgeries or tampering have occurred.
- at least one character of the first piece of information is marked depending on the result of the encryption. Particularly preferred markings are colored or other visually visible markings of the characters of the first information in order to make it easier to check.
- the marking of the first information can be effected by other suitable markings, whereby suitable markings are understood to mean those markings which, if they are not visually recognizable, can be detected with corresponding aids, such as detectors or similar devices.
- suitable markings are understood to mean those markings which, if they are not visually recognizable, can be detected with corresponding aids, such as detectors or similar devices.
- aids such as detectors or similar devices.
- fluorescent or magnetic identifications of the characters of the first information can be provided.
- the algorithm on which the encryption is based can be designed such that only a single piece of information, for example the first information, is included in the algorithm and the result is a marked first piece of information.
- one or more second pieces of information such as serial numbers or the like, are provided in addition to the first piece of information and can be included in the algorithm in addition to the first piece of information.
- the second information need not be provided on the data carrier in a visually visible or legible manner. They can be hidden and / or encrypted in the area or outside the area of the data carrier, which increases the counterfeit or tamper protection.
- the second ones stored in this way are used Information converted into machine-readable or computer-processable characters.
- the algorithm is essentially carried out using operators, with a large number of operators being available for this.
- Operators for bit manipulations such as exclusive OR operators, or binary arithmetic operators, such as addition operators or modulo operators, are preferably used. These operators usually require two operands or information to make one
- encryption can be carried out in a simple manner, without starting from the result, i.e. based on the marked first information, conclusions can be drawn about the implementation of the marking or the specific implementation of the algorithm or the information included in the algorithm.
- An advantageous step of the algorithm is that a sequence of digits is obtained by applying one or more suitable operators to the first and / or second information (s).
- Digits have a limited number of different digit values. This can preferably be done with the help of binary modulo operator, which can be used in addition or as an alternative to the above-mentioned operators.
- the sequence of digits expediently has at least two different digit values, such as “0” or “1”, the digits or the digit values each being assigned a specific identifier, such as a color.
- the digits marked in this way are assigned to the characters of the first information, so that the characters of the first information receive an identification corresponding to the assigned digit. The generated in this way
- Marking the first piece of information is easy to carry out and represents an effective measure to protect against counterfeiting or manipulation.
- a counterfeit or manipulated data carrier can be easily identified by a check.
- the information (s) relevant for the implementation of the encryption is / are initially recorded.
- the algorithm is then applied to the information (s).
- the invention also relates to a data carrier, such as an identity card, credit card or similar value or security document.
- the data carrier according to the invention is produced in particular by the method described above.
- a core idea of the data carrier according to the invention is that the first information is encrypted in such a way that it is stored at least partially marked on the data carrier.
- the marking of the first Information represents an authenticity feature. It is therefore not possible to change the marked first piece of information or parts thereof without this being recognized during a check.
- the visually recognizable markings such as an alternating colored or differently written design of the characters of the first piece of information, are particularly preferred. These visually recognizable markings can be very advantageously integrated into the labeling process, for example if the data carrier is labeled with a laser (in color).
- Embodiments of the invention provide that one or more second information (s) that are used to encrypt the first information are stored inaccessible to unauthorized persons.
- the second information (s) is or are contained in a storage or additional element provided on the data carrier, such as an integrated circuit, magnetic strip or the like. Additionally or alternatively, the second information (s) can be provided outside the area of the data carrier, the second (s) information (s) preferably being stored in an external memory, for example in a central database or similar storage device is or are.
- This constructive measure makes it easier for authorized persons to check, since the second information (s) is open are easily detectable by reading them out of the above-mentioned memories.
- the second information (s) is stored in this way, second information that is uniform for all data carriers can be provided.
- a further simplified possibility of checking the data carrier according to the invention results according to a further preferred embodiment in that the information (s) provided for encryption and the algorithm itself are stored in the integrated circuit of the data carrier.
- the integrated circuit preferably comprises a microprocessor chip. Microprocessor chips are extremely difficult to manipulate and therefore allow the above data to be stored inaccessible to unauthorized persons.
- the second information (s) is or are contained in a pictorial representation provided on the data carrier, the second (n) information preferably being encoded and / or hidden in the pictorial representation ,
- This constructive measure is particularly suitable for ID cards or documents on which a pictorial representation in the form of a user portrait is applied.
- the user portrait represents personal information that is often subjected to forgery or manipulation, for example by the original user portrait being replaced by a new user portrait is replaced.
- Such manipulations are also removed or at least changed in such manipulations so that such an intervention can be determined.

- Fig. 4 is a schematically illustrated arrangement for
- a data carrier 1 which represents an identification card.
- Individual information in particular person- or card-specific information, such as user name 3, serial number 5, user portrait 10, birth dates of the user and the like, information is applied in a legible or visually visible manner on the data carrier 1.
- This individual information can be supplemented by a number of machine-readable characters or lines, which are provided in the specific embodiment in the lower area of the data carrier 1.
- the data carrier 1 can have an integrated circuit 2, which is expedient comprises a microprocessor chip. Alternatively or additionally, a magnetic strip (not shown) can be provided.
- the user name 3 represents a first piece of information and comprises a defined number of characters 4 which are marked on the data carrier 1 such that each character 4 has a specific color.
- characters 4 can differ in terms of their typeface in that the characters 4 are alternately applied to the data carrier 1 in normal, italic or bold type. Such markings can advantageously be integrated into the labeling process, the marked one
- Username 3 or other marked first information is preferably applied to the data carrier 1 by means of laser printing, laser radiation, dye sublimation printing, thermal transfer printing or inkjet printing.

- the user name 3 to be marked is encrypted on the basis of an algorithm.
- the encryption of the user name 3 is described below with reference to FIGS. 2 and 3 in the
- 2 shows a table to illustrate the encryption.
- User name 3 consisting of last name and first name, is arranged character by character in line 11 of the table.
- the user name 3 is encrypted with the serial number 5, which represents a second piece of information intended for encryption.
- the serial number 5 has a defined number of characters 6 and is arranged character by character in line 13 of the table.
- a first step of encryption the characters 4 of the user name and the characters 6 of the serial number 5 are converted into numerical or integer numerical values 7 and 8 using the ASCII character set, as shown in lines 12 and 14 of the table.
- the numerical values 7 of the user name 3 and the numerical values 8 of the serial number 5 are linked to one another numerically or bitwise using an exclusive OR operator XOR. The result of this link is listed in line 15 of the table.
- an exclusive OR operator XOR other suitable operators for bit manipulations or binary arithmetic operators, such as addition operators +, can be applied to the numerical values 7 and 8.
- a modulo operator% which is one of the binary arithmetic operators, is applied to the result of the above link.
- a sequence of digits 9 is obtained, which is listed in line 16 of the table.
- the digits 9 comprise a defined number of different digit values, the number of different digit values being determined by the choice of a divisor T of the modulo operator%. Is the divisor T of
- modulo operator% is assigned the value "2"
- two different numerical values "0 and" 1 "are obtained, as in line 16 of the Table is shown.
- the numbers 9 or the different number values in line 16 of the table are each assigned a specific color or other identification so that each number 9 represents a specific color.
- the digits 9 with the digit value "0" are assigned the color blue, the color blue being illustrated by the symbol o.
- the digits 9 with the digit value "1" are assigned the color red, the color red being indicated by the symbol * is marked.
- the numbers 9 marked in color in this way are added to another
- the choice of the divider T of the modulo operator% essentially depends on how many colors or other markings are to be used. If you want to mark the user name 3 with 3 different colors, for example, the divider T is set to the value "3", as shown in line 18 of the table. This means that a total of three different numerical values "0", "1" and “2 "to which a specific color is assigned. A further color, for example the color green, is assigned to the newly added digit value "2", the color green being identified by the symbol ⁇ . In a further step, the color-coded digits 9 are assigned to the characters 4 of the user name 3, so that from this a tricolor user name 3 results, as shown in line 19 of the table.
- FIG. 3 Another exemplary embodiment for encrypting the user name 3 is shown in FIG. 3 on the basis of a second table clarified.
- the second user information 3 intended for encryption is provided in a modified form.
- the modified user name 3a comprises characters 4a and is arranged in line 13a of the table.
- the modified user name 3a is obtained by shifting the user name 3 arranged in line 11a to the right by one character position and placing the character “k” at the right end of the line at the beginning of the line.
- the user name 3 can be moved by several character positions or are changed in another way, so that a modified form of the user name 3 is obtained. Analogous to the previous example according to FIG.
- the characters 4 of the user name 3 and the characters 4a of the modified user name 3a are converted into numerical or converted integer values 7 and 7a, which are shown in lines 12a and 14a, the exclusive OR operator XOR is applied to the number values 7 and 7a and the result of the combination shown in line 15a is obtained the divider T is equal to "2" (see line 16a) or alternatively the modulo -Operator% with the divisor T equal to "3" (see line 18a) is applied to the result shown in line 15a in order to obtain a sequence of digits 9.
- the numbers 9 have a defined number of different number values depending on the choice or value of the divider T.
- the assignment of defined or different colors is carried out analogously to the example described above in accordance with FIG. 2. It can be clearly seen that by using only different second information, namely by the
- the addition operator + or similar operators can be applied to the numerical values 7 of the user name 3 and to the numerical values 8 or 7a of the serial number 5 or the modified user name 3a.
- the addition operator + or similar operators can be applied to the numerical values 7, 8 and 7a above.
- any visually visible, individual or first information provided on the data carrier 1 can be marked on the basis of the algorithm described above. It is not necessary that the user name 3 or other first information to be marked is always linked with the serial number 5, the modified user name 3a or some other second information.
