Definitions

  • This invention relates to the manufacture of security documents such as passports, licences, currency and the like, and methods of authenticating such documents.
  • Security documents such as passports, identification documents, certificates and licences are frequently the target of counterfeiters and persons wishing to make fraudulent changes to the data contained therein.
  • documents are provided with a number of security elements for checking the authenticity of the document.
  • security elements may include both security element articles which are affixed to or incorporated into the document, such as RFID chips, holographic films, magnetic threads etc, as well as features which are created on the document itself, such as colour-changing inks, security inks (e.g. IR and UV visible inks) and other printed data.
  • Some such security elements may themselves contain personalisation information identifying the owner of the document (e.g. data giving the owner's name, a photograph or biometric data), whereas other security elements may be provided to prevent other data being manipulated (for example a holographic film overlaying printed data).
  • one or more of the security elements are inspected to ascertain whether they provide the expected response or whether the data contained therein corresponds to the person presenting the document, for example.
  • WO-A-00/38932 describes reading the printed serial number from a document such as a bank cheque and performing a cryptographic operation to arrive at a check number which is then printed or otherwise applied to the document. To confirm the document's authenticity, the serial number is read again and compared with the check number.
  • WO-A-00/39953 discloses a watermarking technique whereby information regions on a document (such as printed data, photographs etc) are captured and used to generate a digital watermark which is embedded elsewhere on the document.
  • WO-A-2006/053685 discloses providing a document with one or more barcodes in which data relating to a measurable property of the document is encoded.
  • the measurable properties made use of are: the location of elements of a printed image, or paper fibres and the relative positions of RFID chips or security threads.
  • EP-A-1139302 and EP-A-1501054 describe recording information visible from the document in a RFID chip provided on the document, such as the denomination of a banknote.
  • the present invention provides a method of manufacturing a security document, comprising: providing a first security element article having a corresponding predetermined first unique identification code which is detectable from the first security element article; incorporating the first security element article into a document; generating a machine-readable security feature containing document data representative of the first unique identification code corresponding to the first security element article and of at least a second unique identification code corresponding to a second security element applied to the document; and applying the machine-readable security feature to the document.
  • the present technique provides significant advantages over known methods by including in the machine-readable security feature at least one unique identification code which is integral to a security element article applied to the document. That is, the first identification code is inherent to the security element article (and detectable from the security element article alone, rather than the security document as a whole).
  • the measured characteristics utilised in previous methods are either taken from the relationship between such articles and the remainder of the document, or from the document substrate (or printing thereon), and do not uniquely identify security element articles.
  • the present approach recognises that it is the substitution of security element articles (such as RFID chips, laminate patches and security threads) which is of primary concern in combating counterfeiting, yet such substitution will not be reliably detected by the known methods.
  • the measured characteristics involve the position of a security element article such as a RFID tag relative to the document, it would not be difficult for a counterfeiter to replace the security element article with another of identical appearance in the appropriate position, which would remain undetected.
  • a security element article such as a RFID tag
  • visible information taken from the document is stored within an article such as an RFID tag, this could be replicated by copying the stored data.
  • the security element article By providing the security element article with a unique identifier, such as a number or other code, and recording the identifier in the machine-readable security feature, substitution of the security element article can be readily detected, since the identifier (if any) of the substituted security element article will no longer match the document data embodied in the machine-readable security feature.
  • a second unique identification code detectable from a second security element on the document (which may be another "article" or an element which is intrinsic to the substrate, such as a printed serial number)
  • the security is significantly enhanced since both the unique ID codes must match those stored in the MR feature for a finding of authenticity to be returned. The more security elements and corresponding ID codes that are included in the MR feature, the greater the security.
  • the unique identification codes can take any convenient form, such as alphanumeric, symbolic or even binary, provided they serve the purpose of distinguishing one security element from many others of a similar type. For example, a serial number or barcode could be used.
  • the identifiers may or may not be recognisable to an observer, but preferably, at least some of the identifiers are not recognisable, in order to increase the difficulty of producing a copy.
  • the present invention further provides a method of determining the authenticity of a security document made according to the above method, comprising: reading the machine-readable security feature to retrieve at least one unique identification code contained therein; detecting the first unique identification code from the first security element article; detecting the second unique identification code from the second security element; and comparing the at least one unique identification codes retrieved from the machine-readable security feature with the first unique identification code from the first security element article and/or the second unique identification code from the second security element, to determine whether a security element identified by the machine-readable security feature is present on the document, to thereby determine whether the document is authentic.
  • the authenticity of a document can be judged based on the identity of at least one security element article comprised in the document, which provides a level of security over and above that achieved by simply testing the responses of the security elements or identifying that the elements are provided at the correct positions.
  • the technique also lends itself particularly well to automation, since at least some of the identification codes as well as the security feature itself may be machine-readable. This reduces the possibility of user error.
  • the existence of the ID code of the security element article prior to assembly of the document also provides additional benefits in that, if desired, the relevant ID code for the article could be obtained in advance and later retrieved from a memory store when the MR feature is to be generated to thereby streamline the MR feature generation process and reduce the likelihood of error.
  • the MR feature generation process could involve reading the ID code from the article.
  • the document data representing the identifiers may be embodied in the machine-readable security feature in a number of ways.
  • the document data comprises each of the at least two identifiers. That is, the machine-readable security feature could comprise a machine-readable list of the identifiers.
  • the document data comprises a code in which each of the at least two identifiers are incorporated.
  • the various identifiers could be represented by different portions of a barcode or other graphic. These embodiments could also be used in combination, certain of the identifiers being represented individually, and others incorporated into a code.
  • each of the security elements may be independently allocated its own identifier which may or may not match any of the other identifiers. It is preferable that the first and second ID codes are different to one another, to increase security.
  • the document data embodied in the machine-readable security feature includes all of the identifiers corresponding to the at least some security elements to be identified.
  • each of the security elements is associated with the same identifier, common to all of the security elements. That is, each of the security elements is provided with the same detectable serial code or other identifier. In this case, the machine-readable security feature need only contain that same identifier, this identifier being compared against the identifiers detected from each of the security elements to be identified.
  • the machine-readable security feature may be provided on the document in a number of ways.
  • the machine-readable security feature is readable by optical recognition (within or outside the visible spectrum).
  • the machine-readable security feature could be printed onto the document, or otherwise applied by means of a label, a transfer or the like.
  • the feature could also comprise perforations or variations in the document thickness such as a watermark, which can be detected in transmitted light.
  • the document data is encrypted such that it is not directly intelligible to an observer. That is, even if the feature itself is visible to a user, it is not understandable without first decoding its meaning.
  • the machine-readable security feature comprises a 2D barcode, scrambled indicia or a digital watermark.
  • the machine- readable security feature is not apparent in the visible spectrum, preferably being formed of a UV, IR or fluorescent ink. As well as hiding the feature from potential counterfeiters, this makes it more difficult to copy since such techniques are not readily available.
  • the machine-readable security feature comprises a RFID chip or a magnetic strip having the document data stored therein. Whilst such features may themselves be visible to an observer, the data therein is not readily accessible without the appropriate reading apparatus. It is also more difficult to manufacture counterfeit features of this sort.
  • the first security element article can be of any type which is pre-manufactured and then affixed to or incorporated into the document substrate.
  • the first security element article comprises a contactless, readable data store, preferably a RFID chip, containing machine-readable data including the first unique identification code.
  • the first security element article comprises a film for application to the document, the film having the first unique identification code printed, engraved or perforated thereon.
  • the film is a polymeric film and may comprise optically variable regions.
  • the first security element article comprises a security thread, preferably a magnetic thread, containing machine-readable data including the first unique identification code.
  • the first security element article may comprise an optically active element, preferably a hologram, carrying the first unique identification code.
  • the optically active element is modified to carry the first unique identification by printing, laser engraving or perforation.
  • the second security element could comprise any of the above mentioned exemplary security element articles (containing the second unique ID code), or could comprise a feature inherent to the document substrate, printed, engraved, perforated or otherwise.
  • the method further comprises applying one or more additional security elements to the document, each additional security element having a respective unique identification code, and incorporating the respective unique identification codes into the document data before the machine-readable security feature is applied to the document.
  • the additional security element(s) could comprise elements of any of the types already discussed with respect to the second security element.
  • at least one of the additional security elements may comprise at least a portion of the document surface, and the method further comprises measuring a surface characteristic of the document surface portion and recording the measured characteristic to provide the corresponding unique identification code.
  • the MR feature and all of the other security elements it references are firmly linked to the document substrate itself.
  • any dimension, thickness, weight or other measurable characteristic of the document, or a feature thereof could be used.
  • the surface characteristic is obtained by laser surface analysis of the at least a portion of the document surface.

  • the code 16a' provided on the laminate film is also "GB1234996", as is the passport number both laser-perforated 17' and printed 19' onto the document.
  • the RFID chip 18' is programmed with the code "G1234996" in its Datagroup 13 or Datagroup 1 sector, for example.
  • the same code "GB1234996” is stored in the document data embodied by the machine- readable security feature 20', which in this case is a 2D barcode but could take any appropriate form as described in the previous example.
  • the document data could include the code repeated for each security element.
  • the code since the code is the same for all security elements 15' to 19', the code need only be stored once in the machine-readable security feature 20', and can be checked against each of the selected security features.
  • the first and second examples could also be used in combination with each other, for example, a code common to a subset of the security elements (e.g. passport numbers 17' and 19') could be stored alongside individual identifiers for other elements (e.g. the RFID chip 18' and the laminate code 16a').
  • the second embodiment also makes use of an optional security element 30 in the form of a measured characteristic of the document 10'.
  • the characteristic is the surface roughness of the document substrate, which can be detected by laser surface analysis. It has been found that many document substrates, such as paper, exhibit surface roughness at a microscopic level which varies from place to place on the substrate, and between substrates (even those of the same type). Hence measuring and recording the surface roughness of a defined area of a substrate is akin to recording a person's fingerprint.
  • Security element 30 therefore consists of a stored surface roughness profile which has been measured for at least a portion of the surface of the document 10', preferably from a page other than that on which the feature 20' is placed.
  • the measurement could be taken from an element (including a printed element) applied to the document 10' rather than the document itself.
  • the exact dimensions of a line printed in invisible ink could be recorded. Or, if there is a measurable variation in standard page dimensions, weight or thickness, any one or more of these could be measured and recorded.
  • security elements can be a large or small as is required, and could for instance include such features as a laser perforation check digit, laminate film number, taggant information (RFID chip number) etc., as described above.
  • the security elements selected will depend on the application for which the document is intended. Further, it should be noted that not all of the security elements provided on the document need be provided with an identifier and/or recorded in the machine-readable security feature. For example, the document may additionally be provided with holograms, embossings, watermarks or any other security elements which may or may not be associated with an identifier recorded in the security feature.
  • each identification code need not be 'programmed' as such, into the respective security element.
  • a first example is the use of a measured characteristic of the document surface, identified as security element 30 above.
  • one of the security element articles is an RFID chip
  • its identifier can be descriptive of its contents, for instance if the chip contains three Datagroup sectors 1, 2 and 7, then this information can be stored in the machine-readable security feature as the identifier. If the chip is substituted or the contents of the chip are modified (e.g. a Datagroup is removed), this will be identified by checking the machine-readable feature.
  • the identifier could include a signature of some of the data in the RFID chip.
  • the signature would be generated using the same key as that used to sign the chip data and could be verified using the "Document Signer" key stored in the chip.
  • This is a digital certificate containing a public key which can be used to decrypt a digital signature and verify that it was encrypted with a corresponding private key. The certificate will have been digitally signed by a trusted Certificate Authority and therefore can be validated for authenticity.
