A visual localization support system is provided. The visual localization support system includes one or more guidance indicators place on a road surface of a roadway, wherein the one or more guidance indicators each include a matrix barcode that uniquely identifies a location by latitude, longitude, and altitude, and describes an affine shape of the guidance indicator.

In some instances, a method for verifying communication paths is provided. The method comprises: obtaining, from a first user device, a request to access content associated with a relying party system, wherein the request indicates user credentials and a first session identifier (ID); obtaining one or more quick response (QR) codes and a second session ID associated with a first QR code of the one or more QR codes, wherein the relying party system generates and provides the first QR code to the first user device; and verifying the first session ID and the second session ID, wherein the relying party system grants the first user device access to the requested content based on the verification.

AI based steganographic systems and methods are described for analyzing pixel data of a product to detect product counterfeiting. An AI based imaging model is trained with pixel data of a plurality of training images comprising (1) a first subset of images each depicting at least a portion of the product having one or more authentic steganographic features, and (2) a second subset of images each depicting at least a portion of the product devoid of the one or more authentic steganographic features. A new image comprising pixel data of the product may be received and analyzed by the AI based imaging model to detect the pixel-based feature presence or absence of authentic steganographic feature(s) to determine an image classification of the product. The AI based steganographic systems and methods may detect whether the product is authentic or counterfeit based on the image classification.

Provided is a Device, a System, applications and an associated Ecosystem for the consistent and reliable production, creation, generation, management and utilization of two-dimensional (‘2D’) barcodes (‘Codes’) featuring embedded Images, designating the alignment position and alignment size of the embedding Images in 2D Codes and enabling the corresponding outputted Code files by the Device System to be downloaded and or showcased digitally within all forms of digital advertising, media, television, mobile telephony and the world wide web as well as integrated with the production processes for consumer products and packaged goods, printed products, merchandise and other items featuring such 2D Codes creating a public telecommunications platform and or private intranet services featuring a searchable database, directory and or registry of the 2D Codes with embedded Images that have been created by, produced by and outputted by the Device or System.

Disclosed is a QR code extension method, comprising the following steps: SI. obtaining data encoding information, and determining the number of positioning points based on a data encoding length; S2. partitioning a data area according to different shapes, and adjusting a parameter of each data partition by adjusting the number of transverse and/or longitudinal unit QR codes; and S3, drawing a QR code, and outputting a result. The method is more flexible, and can make a QR code realize one-way or two-way extension, and the length and the width of a data area can be slightly adjusted to ensure that the capacity of the data area is close to the size of data information, so that capacity in per unit space is optimized.

A reading device, a reading method and a reading program that can easily and quickly read a composite symbol, and a settlement processing method are provided. A moving image of a composite symbol which includes a plurality of symbols emerging in the same location and whose appearance changes depending on a viewing angle, is captured. The symbols included in the composite symbol are detected from the moving image obtained by image-capturing. Authenticity of the composite symbol is determined based on the obtained moving image.

Aspects of the present invention disclose a method, computer program product, and system for determining information based on a received image. The method includes one or more processors receiving image data from a computing device. The method further includes one or more processors identifying an object included in the received image data. The method further includes one or more processors determining a value that corresponds to the identified object included in the received image data. The method further includes one or more processors determining whether the determined value corresponds to a defined action. Another aspect of the present invention discloses an apparatus that includes a foreground label overlaying a background label, and a measurement device coupled to the foreground label. The measurement device is capable of movement in response to observing measurement data.

A method (30) for securing a document, which comprises: a step (301) of statistically determining the average magnitude of an unpredictable print variation; a step (302) of generating a message representative of at least one predefined print variation rate; a step (307) of encoding the message in a 2D barcode comprising a plurality of cells, the cells comprising two areas: a first area representing a symbol and a second area, representing a matrix of dots of dimensions smaller than the dimensions of the second area and having at least one geometric characteristic similar to the amplitude of the statistically determined unpredictable print variation; and a step (310) of printing the document with the barcode, the print causing the unpredictable variation.

A controlling device scans a label of a network-connected device to obtain a first set of information from a primary layer of the label, where the first set of information is about the network-connected device. The controlling device scans the label to obtain a second set of information from a secondary layer of the label, whereby the secondary layer is distinct from the primary layer. The controlling device transmits a request to a device server associated with the network-connected device to obtain device records for the device, whereby the request includes the second set of information. In response to the request, the controlling device receives the one or more device records.

A distance measuring element including: at least one first subpattern having a nonrepeating structure of values in a defined first value range; and at least one second subpattern, which, in comparison with the first subpattern, has a non-repeating structure of values in a second value range, the second subpattern having no values in the defined first value range, the at least two subpatterns being superimposed by summing over a defined surface area to form a surface pattern; the minimum distance between the values of the second value range being greater than the maximum value of the first value range.
