Definitions

  • the present invention relates to the investigation of the authenticity of objects.
  • the invention more particularly relates to a method, device and computer program for enabling the investigation of the authenticity of an object as well as a method, authentication data handling device and computer program product for investigating the authenticity of an object.
  • Illegal copying of objects is a big problem for companies, organisations and individuals. Illegal copying involves such things as copying products to be sold, counterfeiting, as well as copying of security items, such as identity cards, credit cards, bank cards and certificates. Counterfeiting is an increasing problem for manufacturers and users. Through counterfeiting copies of goods appear that resemble the goods of the rightful owners. This can lead to considerable economical losses for the companies that provide products.
  • an object may be a product or the package provided for a product.
  • the objects are here identified by their unique code.
  • a system for identifying a code then normally involves the reading of the code, which code is attached to or integrated into the object. Reading of the code is then performed using a reading device.
  • the code is originally in a non-numerous mode like an image, a barcode, or a combination of properties or numeric values, that information is used for calculation of an identification number, an ID.
  • the object is uniquely identified by its code, and it's ID.
  • the code and the ID can be identical or unambiguously correlated to each other.
  • the ID is entered into a system which enables information exchange.
  • the system provides information related to the specific ID, which information has been stored to the system at an earlier stage.
  • systems for providing information about the whereabouts of an item by reading the item's unique ID are known. This is commonly used in track & trace systems. It is also known in the art that the unique ID of an item or product can be used for authenticity requests.
  • For authentication of a product it is checked whether the product's ID has been issued by the manufacturer and whether it is currently in circulation. Further rules may be applied to include analysis of geographical information, time stamps, or supply chain information prior to authentication.
  • the authentication database of issued IDs is maintained by the manufacturer or by a third party on behalf of the manufacturer. It can also contain further data related to the product or production.
  • Systems providing track & trace or authentication information are either based on a centralized database or the database is distributed among several information providers. In the latter case software is used for compiling the information from several information providers.
  • the information can be exchanged remotely as long as a connection is established between a requesting party and the database.
  • connection to the centralized or distributed database can be made via a network connection.
  • the network can be a private network or it can be internet-based. It can also include additional telecommunication means like mobile phones or Bluetooth etc.
  • the information which is stored in connection to track & trace information related to a product is usually product name, tracking history (where and when the ID of an item has been read), expiry date of product, and further product description (for example dosage and package size).
  • Connected to the network are at least one or several databases for maintaining the database information.
  • Connected to the network are also one or more reader or interface devices which enable input of ID for requests or for registration of a reading event.
  • Systems are also known in the art for integration of security features in a product.
  • devices are used for detecting and controlling security features on products.
  • security features which have been applied to products are: fluorescent markers in packaging materials, metal threads in banknotes, micro-text o printing, code printing, taggants, and many, many others.
  • signature is used here.
  • the signatures are either detected on-site by appropriate equipment (for example an UV- lamp is used to look at UV-fluorescent features), or specialized readers that signal 5 authenticity in case they detect a certain fluorescence pattern.
  • appropriate equipment for example an UV- lamp is used to look at UV-fluorescent features

  • the authentication data handling device 22 compares the received material properties P1 with the measured material properties P1 ' and bases the indication of authenticity also on this comparison.
  • the measurements can be multi-tasks like for example frequency scanning in certain sequences and frequency bands whereas the response is delivered to the authentication system and a comparison with identity related data is performed to check the identity of the object having a certain identity.
  • the fluorescence in a certain area may be measured while scanning the irradiating frequency. This can be done by tuning a laser or by irradiation with multifrequency light which passes a prism.
  • the fluorescence profile would depend on the materials used in manufacturing of the object. In many cases, materials have very specific fluorescence 5 profiles and can as such reveal copied materials with different origin. This is the case, for example, for some paperboard substrates.
  • fluorescent taggants or markers can be used to define a selective fluorescence pattern. This would provide the object with an additional security feature since it is not sufficient to provide a feature giving a certain response at a o certain frequency but the response would have to be correlated for several frequencies.

Abstract

Dispositif (10) d'étude de l'authenticité d'un objet (18), comprenant un module (16) de modification d'objet servant à doter l'objet (18) d'une identité et une région de l'objet d'une structure graphique, et un module de commande (14) servant à sélectionner une variation élémentaire détectable, à donner au module (16) de modification d'objet l'instruction de doter l'objet (18) d'une structure graphique incorporant la variation élémentaire sélectionnée, et à stocker l'identité ainsi que des données de variation élémentaire de référence identifiant la variation élémentaire sélectionnée dans une base de données de produits (20). Un dispositif (22) de traitement de données d'authentification reçoit une identité d'un objet (18) et localise des données de variation élémentaire de référence dans une base de données de produits (20) de manière à comparer les données à une variation élémentaire de l'objet et à établir l'authenticité de l'objet.
