Embodiments of the present application provide a method and an apparatus for displaying an identification code of an application. The method includes: acquiring an identification code in a target application in a system user interface (UI), where the identification code is generated by the target application according to user information in the target application; and displaying the identification code in an icon-display region of the target application in the system UI.

A data carrier having one optically variable element, at least one background element, which is arranged after the at least one optically variable element when seen along an extension direction, and at least one security element, which is constituted by at least a part of the at least one optically variable element and at least a part of the at least one background element. At least one tamper-indicating element is provided, which is arranged at least in a region between the at least one optically variable element and the at least one background element with respect to the extension direction. The tamper-indicating element is configured such, that the at least one optically variable element and the at least one background element at least in a region of the at least one security element are at least partially separable from one another upon an application of force onto the at least one optically variable element along a first pulling direction running opposite to the extension direction and/or upon an application of force onto the at least one background element along a second pulling direction running along the extension direction, whereby the at least one security element is at least partially separated into two or more parts.

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.

A method for generating word code, a method and device for recognizing codes are provided, and they are falling within the field of machine visual recognition. The method for recognizing word code includes: acquiring an image containing word codes, and recognizing target words therein; splitting the target words according to the same rule, and then recognizing all visual anomaly split sequences, and performing determination on the word codes, if the word codes are generated on the basis of an encoding mechanism designed by a system, directly reading same and performing invoking; otherwise, invoking a pre-inputted target file of the word codes according to target word meaning sequence numbers and visual anomaly sequences numbers corresponding to the word codes.

The technology described herein generates a unique identifier for a visual media that comprises pre-printed visual indications on the visual media and a user's handwritten signature. The location of the signature on the visual media can be determined by including preprinted fiducial marks on the visual media. The fiducial markers act as landmarks that allow the size and location of the signature to be determined in absolute terms. The unique identifier is then stored in computer memory on a user-experience server. The user-experience server can associate the unique identifier with a digital asset, such as an image or video, designated by the user. When the unique identifier is provided to the user-experience server a second time, the digital asset can be retrieved and output to the computing device that provided the unique identifier.

To easily determine whether an information code has been replaced, an information processing device obtains, based on original information obtained by photographing an optically readable information code and decoding the same, first class information indicating a class into which an object visually represented by first visual information which should be displayed together with an information code is classified. The information processing device obtains second class information indicating a class into which an object visually represented by second visual information photographed together with the information code because of display together with the information code is classified. The information processing device compares the first class information with the second class information. The information processing device controls, based on a result of the comparison, execution of predetermined processing using the original information.

Systems and methods for using facial patterns for information access via optical barcodes are provided. In example embodiments, a computer accesses an image. The computer determines, using facial recognition, that the accessed image includes a face. The computer determines, using the face, an orientation of the image. The computer decodes, based on the determined orientation of the image, data encoded within the geometric shape. The computer may then access a resource based on the decoded data. In some aspects, a graphical output may be presented on a display device indicating the accessed resource.

The present invention relates generally a method to authenticate a data carrier, such as passports, licenses, identification card . . . by hiding at least two optically encoded image within a data carrier so that the data carrier is authenticated through at least two factor authentication process. In the methods of the present invention, at least two reliable, readable optically encoded image are hidden within the data carrier wherein each of the encoded image is visible through a same decoder device but under different specific lighting conditions without the former having influence on the quality of the latter. The authentication methodology of the present invention provides an improved security, being even more difficult to reproduce by infringers, even more difficult to remove, replace or exchange and easy to check.

Systems and methods for custom functional patterns for optical barcodes are provided. In example embodiments, image data of an image is received from a user device. A candidate shape feature of the image is extracted from the image data. A determination is made that the shape feature satisfies a shape feature rule. In response to the candidate shape feature satisfying the shape feature rule, a custom graphic in the image is identified by comparing the candidate shape feature with a reference shape feature of the custom graphic. In response to identifying the custom graphic, data encoded in a portion of the image is decoded.

An image reading apparatus includes a first light source, a second light source, a visible imaging sensor, an invisible imaging sensor, and a reduction unit. The first light source irradiates an object with visible light. The second light source irradiates the object with invisible light. The visible imaging sensor reads a visible image of the object. The invisible imaging sensor reads an invisible image of the object. The reduction unit reduces a visible wavelength component of light received by the invisible imaging sensor.
