A system, method, and computer-readable medium for decoding an encoded geometry, comprising: scanning an encoded geometry, the scanning comprising scanning a plurality of multi-dimensional symbols of the encoded geometry; identifying each of the plurality of multi-dimensional symbols; decoding each identifier multi-dimensional symbol to provide encoded geometry information; accessing an encoded geometry repository; and, retrieving data associated with the encoded geometry information.

A code includes a first part printed by using a first pigment, and a second part printed by using a second pigment which is easier to discolor than the first pigment, wherein the code is decodable by using information about discoloration of the second pigment.

A system, method, and computer-readable medium for decoding an encoded geometry, comprising: scanning an encoded geometry, the scanning comprising scanning a plurality of multi-dimensional symbols of the encoded geometry; identifying each of the plurality of multi-dimensional symbols; decoding each identifier multi-dimensional symbol to provide encoded geometry information; accessing an encoded geometry repository; and, retrieving data associated with the encoded geometry information.

A system, method, and computer-readable medium for performing a physical part identification generation operation, comprising: defining design parameters for an encoded geometry; identifying data to be encoded within the encoded geometry; converting the data to be encoded to the encoded geometry; and, producing a part with the encoded geometry, the encoded geometry passively representing information.

There is provided an information processing device to realize more efficient reading of a target code. The information processing device includes an acquisition unit that acquires a target code from a captured image to acquire information from the target code. The acquisition unit acquires a target code from a captured image of a tile code in which a plurality of identical target codes are arranged at predetermined intervals.

Methods are disclosed for hiding a two-dimensional code such as a QR code within a visible layer of randomly scattered line segments. The scattering parameters comprise the length of successive line segments as well as their relative offsets. These parameters are stored in a key. The hidden 2d code is recovered with a computing device such as a smartphone carrying out the acquisition, perspective correction, and rectification of the visible layer of scattered line segments. This computing device synthesizes in its memory according to that same key a hidden layer of scattered line segments. The superposition of the acquired, perspectively corrected and rectified visible layer and of the hidden layer yields an image from which the hidden 2D code is revealed. The presented methods enable the secret transmission of information from the real world of documents and objects to databases located on computer networks.

Exemplary embodiments use a single, physical embodiment that compiles independent machine-readable codes together with little to no space in between codes. This physical embodiment is in two primary formsadhesive tape or fabric strips with hook and loop backing. A code reader device, with software compatible with the machine-readable codes, can rapidly or simultaneously aggregate independent codes together on the physical embodiment in order to assign them to one or more digital addresses.

A system, method, and computer-readable medium for decoding an encoded geometry, comprising: scanning an encoded geometry, the scanning comprising scanning a plurality of multi-dimensional symbols of the encoded geometry; identifying each of the plurality of multi-dimensional symbols; decoding each identifier multi-dimensional symbol to provide encoded geometry information; accessing an encoded geometry repository; and, retrieving data associated with the encoded geometry information.

A single dual-sided product placement and information strip includes a first side with product information for consumers and a second side with product placement information for placing products on a display shelf. The dual-sided product placement and information strip enables information necessary for consumers to be printed on the first (consumer-facing) side and information that assists stockers to place products on shelves to be printed on the second (opposing) side. Also disclosed are systems and methods for formatting and printing the dual-sided product placement and information strips. The single dual-sided product placement and information strip may be printed alone or in a single sheet along with one or more other dual-sided product placement and information strips.

An information bearing device comprising a data bearing pattern, wherein the data bearing pattern comprises a plurality of data defining elements, the data defining elements being spatially distributed to define a set of spatial frequency data, and the set of spatial frequency data comprising a plurality of frequency data elements (F.sub.1, F.sub.2, . . . , F.sub.n); and wherein each frequency data (F.sub.i) has a data frequency magnitude (f.sub.i) and a data frequency angle (.sub.i), the data frequency magnitude being above a first characteristic spatial frequency (f.sub.A) which corresponds to a characteristic frequency of a staple or commonplace image reproduction apparatus, the characteristic frequency representing an image data frequency above which reproduction quality by the staple or commonplace image reproduction apparatus begins to drop substantially.
