The invention relates to a method for authenticating an illustration, comprisingencoding a message in the form of a two-dimensional barcode comprising blocks, each block coding a fragment of said message and comprising a set of coding sub-blocks, each sub-block comprising a set of binary elements. It is essentially characterised in that the encoding comprises prior steps consisting in:defining or identifying a set of noteworthy points in the illustration,calculating a set of attributes depending on certain at least of the noteworthy points,selecting, among the calculated attributes, at least one attribute allowing a digital fingerprint to be definedoptionally compressing said digital fingerprint,optionally signing said digital fingerprint by means of a cryptographic signature, andrecording in the message one among:a set of at least one attribute,the digital fingerprint,the compressed digital fingerprint, andthe signed and optionally compressed digital fingerprint.

A laminate includes: a first laminate member; a second laminate member; and a hidden print formed by printing invisible ink between the first laminate member and the second laminate member. The hidden print is configured to absorb electromagnetic radiation outside the visible range. When irradiated with electromagnetic radiation outside a visible range that has passed through at least one of the first laminate member and the second laminate member, the hidden print absorbs the electromagnetic radiation to thereby show a sign, and, when irradiated with visible light, the hidden print does not show the sign.

An article and method of manufacturing an authenticatable finished fabric and article comprising the steps of: obtaining an original fabric article comprising authentic fiber, the original fabric article being possessed at some time by at least one person; breaking the original fabric article into authentic fiber components; blending the authentic fiber components with virgin fiber to make a authentic fiber blend; generating a authentic fiber blend yarn; weaving or knitting a finished fabric that is configured to form a binary code from a mixture of the authentic fiber blend yarn and a filling yarn; and creating a first level authentication and an second level authentication of the finished fabric with the first and second level authentication being non-interacting or independent.

Disclosed herein is a novel invention of Digitalized High Value Paper Currency (DHVPC) and its overall processes for the printing, registration, distribution, recording and monitoring of transactions through a specially designed Online Portal. During the DHVPC registration, opening of additional ledger window with simultaneous automatic generation of a window in the Online Portal of Reserve Bank/Central bank of each nation takes place with automatic updating of transactions of DHVPC. This Invention provides 100% protection from counterfeiting of Paper Currency, monitoring, tracking of currency, blocking of illegal transactions, value protection in unforeseen situations, easiness to carry and handle, faster scanning of currency and improved security. The DHVPC transactions can be done through Commercial and Scheduled Banks or ATM/CDM or Net Banking. Counterfeiting is 100% impossible because, the registration of DHVPC is possible only through Reserve bank/Central bank of each nation, parallel entry of currency into the circulation is not possible.

A method for authenticating an object, comprising determining a physical dispersion pattern of a set of elements, determining a physical characteristic of the set of elements which is distinct from a physical characteristic producible by a transfer printing technology, determining a digital code associated with the object defining the physical dispersion pattern, and authenticating the object by verifying a correspondence of the digital code with the physical dispersion pattern, and verifying the physical characteristic.

An anti-counterfeiting method involves dividing a barcode image into a plurality of modules; extracting a respective inertia of a gray level co-occurrence matrix for each of the plurality of modules; acquiring an image of a printed candidate bar code; generating a sorted list (using extracted intertias) for the plurality of modules of the image of the printed candidate barcode; in a first range of magnitudes, comparing the sorted list for the image of the printed genuine barcode with an equivalent sorted list for the image of the printed candidate barcode; and in a second range of magnitudes, comparing the sorted list for the image of the printed genuine barcode with the sorted list for the image of the printed candidate barcode, wherein the second range is different from the first range.
