Definitions

  • the present disclosure generally relates to the field of anti- counterfeiting articles. Particularly, the present disclosure provides a security article for anti-counterfeiting and a process for production thereof. Aspects of the present disclosure also relates to a method of registering digitized information and reference image(s) for authentication of a security article, a method of authenticating a security article.
  • An aspect of the present disclosure provides a security article for anti-counterfeiting (100), said security article including: a physically unclonable function (PUF) comprising a plurality of particles (110) distributed across a film (120); and an indicia (130) demarking an area (140) of the film with registrable particles (110a) out of said plurality of particles (110).
  • the plurality of particles (110) are randomly distributed across the film (120), said film comprising 2 to 200 particles per square cm, and said plurality of particles (110) collectively covering 0.01% to 90% area of the film.
  • the plurality of particles (110) are 3D particles with size ranging from 100 microns to 5000 microns.
  • Another aspect of the present disclosure relates to a process for preparing a security article for anti- counterfeiting (100), the process comprising the steps of: preparing a film (120) having a plurality of particles (110) distributed across the film (120); and associating an indicia (130) with said film (120), said indicia (130) affording demarcation of an area (140) of the film with registrable particles (110a) out of said plurality of particles (110).
  • the step of associating the indicia with the film comprises affixing the film (120) to a substrate film (150) defining the indicia.
  • FIG. 2B-2E illustrate exemplary views of the security article showing different figures that serves as an indicia, in accordance with embodiments of the present disclosure.
  • FIG. 4 illustrates an exemplary flow diagram showing steps involved in a process for preparing a security article for anti-counterfeiting, in accordance with an embodiment of the present disclosure.
  • FIG. 5 illustrates an exemplary flow diagram showing steps involved in process of preparing a film having a plurality of particles distributed across the film, in accordance with an embodiment of the present disclosure.
  • FIG. 8 illustrates an exemplary flow diagram showing steps involved in for authentication of a security article, in accordance with an embodiment of the present disclosure.
  • Still further aspect of the present disclosure relates to a method of authenticating a security article (100), said security article including a physically unclonable function (PUF) comprising a plurality of particles (110) distributed across a film (120), an indicia (130) demarking an area (140) of the film with registrable particles (110a) out of said plurality of particles (110), and any or a combination of a hologram, a ID random code, a ID serial code, a 2D random code, a 2D serial code and an Optically Readable Alpha-numeric code, the method comprising the steps of: capturing, at one or more processors, one or a plurality of images of the security article; extracting, at one or more processors, an information embedded within said any or a combination of hologram, ID random code, ID serial code, 2D random code, 2D serial code and an Optically Readable Alpha-numeric code; identifying, at one or more processors, a registered reference image of said
  • the security article authentication system for authentication of the security article that comprises a physically unclonable function (PUF) comprising a plurality of particles (110) distributed across a film (120), and an indicia (130) demarking an area (140) of the film with registrable particles (110a) out of said plurality of particles (110), may not require the information extracting unit 914.
  • PAF physically unclonable function
  • the information embedded within any or a combination of hologram, ID random code, ID serial code, 2D random code, 2D serial code and an Optically Readable Alpha-numeric code aids in identifying one or a set of reference images against which the test image needs to be compared for verification and authentication, greatly enhancing the speed of analysis (i.e. the processing speed is increased by several fold).
  • the matching and authentication unit 920 further facilitates matching of the extracted pattern against the reference image(s) of registrable particles, and a determination is made if the registered reference image matches with the extracted pattern. Based on the determination the security article is authenticated.
  • the system 902 can include one or more processors (interchangeably can be referred to as processors, herein) of control unit which can be communicatively coupled to a memory which can store one or more instructions to be executed by processors.
  • the system 902 may not be connected to the network at all and may be a standalone device which has alphanumeric character stored on the system itself.
  • the system 902 may be implemented on a mobile communication device.
  • provision of any or a combination of hologram, ID random code, ID serial code, 2D random code, a 2D serial code and an Optically Readable Alpha-numeric code on the security article can afford embedding the information, such as code or number denoting a security article or a class of security articles, against which one registered reference image or a set of registered reference images of registrable particles may be stored in the database. Provision of storage of one registered reference image or a set of registered reference images against a code or number (or any such information) affords significant enhancement in speed of the matching and authentication step(s) by the processor(s)/engine(s) as compared to the conventional systems, wherein the pattern produced by the particles/PUF needs to be compared with numerous registered images.
  • Bus 1120 communicatively couples processor(s) 1170 with the other memory, storage and communication blocks.
  • Bus 1120 can be, e.g. a Peripheral Component Interconnect (PCI) / PCI Extended (PCI-X) bus, Small Computer System Interface (SCSI), USB or the like, for connecting expansion cards, drives and other subsystems as well as other buses, such a front side bus (FSB), which connects processor 1170 to software system.

  • PCI-X PCI Extended
  • SCSI Small Computer System Interface
  • FFB front side bus
  • the present disclosure provides a method of manufacturing a security article that is cost-effective.
