An economical and accurate method of classifying a consumer good as authentic is provided. The method leverages machine learning and the use of steganographic features on the authentic consumer good.

Aspects of the present disclosure involve systems, methods, devices, and the like for generating an unobtrusive and discrete barcode used for debugging. In one embodiment, a system is introduced that enables the tracking of application interactions on a user device. The tracking can include the generation of a debug id which can include a discrete string used to describe locations, preferences, and interactions with a user device application. The string may then be converted into a corresponding barcode which can be discretely displayed on the user interface of the application. In another embodiment, the barcode may be captured and/or retrieved for use in debugging the application, in an instance where an application malfunction is encountered.

A method and system providing an anti-counterfeiting label or mark, using ordinary inkjet printers, take advantage of a phenomenon called a coffee ring pattern, something that inkjet printers. Even the same inkjet printer can output different patterns under different conditions. As a result, the likelihood of reproduction of a particular printer's coffee ring pattern using another printer is so low as to be negligible. It is possible to capture images of the coffee rings using a smartphone camera. The coffee ring approach may be used on any labels or packages on which inkjet printing can be used.

Disclosed is an apparatus for generating a composite two-dimensional code, comprising: a two-dimensional code encoding module 1, a two-dimensional code pattern generating module 2, a hidden information encoding module 3, a hidden information pattern generating module 4, a recoding region setting module 5, an pattern compositing module 6, and an output module 7. The two-dimensional code encoding module 1 converts the inputted two-dimensional code information into a binary codeword sequence to generate two-dimensional code coding information; the two-dimensional code pattern generating module 2 generates a two-dimensional code pattern based on the two-dimensional code coding information; the hidden information encoding module 3 converts the hidden information into a binary codeword sequence to generate recoding information; the recoding region setting module 5 sets, in the two-dimensional code pattern, a recoding region for encoding the hidden information; the hidden information pattern generating module 4 generates a hidden information coding pattern formed by dark-colored blocks and light-colored blocks based on the recoding information; and the pattern composing module 6 adjusts a block distribution in the recoding region of the two-dimensional code pattern based on the hidden information coding pattern so as to encode the hidden information.

An integrated certification system is a system for performing integrated certification on products to which genuine-product certification labels are attached. The integrated certification system includes an integrated certification management server. The integrated certification management server includes a distribution management module configured to acquire distributor identification information and a distribution number of each of the products from each distributor and match the distribution number to an identification number assigned to a corresponding distributor and a genuine-product certification module configured to receive a genuine-product certification request including user-related information and an identification number extracted from each of the genuine-product certification labels from a user terminal and perform genuine-product certification according to the received genuine-product certification request.

A unique secured product identification method, system, and apparatus for product such as precious gemstones prevent counterfeiting by incorporating a marked product with fake identification (ID) mark or fake barcode. Authentication process requires at least two identifying data sets, an overt mark or overt data and covert data. The overt data may be a unique product identifier like a barcode. Covert data may be any additional data derived from the specific product. Additional data points come from a created data point not originally part of the product, or a unique data point already existing in the product but not existing in any other similar product. Product is authenticated when the combination of data sets compared to original data sets creates positive product identification. Authentication may be done with centralized, or de-centralized databases. A partially or non-automated method may be implemented, for example, where a barcode links to a database.

Information is stored in an optical element in the form of a glass or plastic body embodied as spectacles lens, spectacles lens blank or spectacles lens semi-finished product. The information in the form of data is stored on or in the glass or plastic body by creating at least one marking with a marking system. The marking can be read by a reading apparatus. The marking system has an interface for reading information individualizing the optical element. The marking is created permanently by the marking system on or in the optical element at a definition point of a local body-specific coordinate system set by two points on or in the optical element. In this body coordinate system, the manufacturer specifies the position of the lens horizontal and/or the far and/or the near and/or the prism reference point.

An electronic device comprising a semiconductor chip which comprises a plurality of structures formed in the semiconductor chip, wherein the semiconductor chip is a member of a set of semiconductor chips, the set of semiconductor chips comprises a plurality of subsets of semiconductor chips, and the semiconductor chip is a member of only one of the subsets. The plurality of structures of the semiconductor chip includes a set of common structures which is the same for all of the semiconductor chips of the set, and a set of non-common structures, wherein the non-common structures of the semiconductor chip of the subset is different from a non-common circuit of the semiconductor chips in every other subset. At least a first portion of the non-common structures and a first portion of the common structures form a first non-common circuit, wherein the first non-common circuit of the semiconductor chips of each subset is different from a non-common circuit of the semiconductor chips in every other subset. At least a second portion of the non-common structures is adapted to store or generate a first predetermined value which uniquely identifies the first non-common circuit, wherein the first predetermined value is readable from outside the semiconductor chip by automated reading means.

Systems and methods are provided for decoding secure tags using an authentication server and secure tag reader. The system can include at least one processor and at least one non-transitory memory. The memory can contain instructions that, when executed by the at least one processor, cause the secure tag reader to perform operations. The operations can include detecting a potential secure tag in an image and generating a normalized secure tag image using the image and a stylesheet. The operations can further include providing an identification request to an authentication server, the identification request including the normalized secure tag image. The operations can additionally include receiving rules for decoding tag data encoded into the secure tag as tag feature options and decoding the tag data using the received rules.

The present disclosure is drawn to print media. In one example, a print medium can include a print surface and a microembossed identification code applied to the print surface. The microembossed identification code can include multiple microembossed features grouped together at a location on the print surface. The microembossed features can have a feature height from 5 m to 200 m and can be spaced relative to adjacent microembossed features at from 20 m to 1,000 m.
