Disclosed are a QR (Quick Response) code having hidden codes and methods for forming and identifying the hidden codes. The QR code comprises a plurality of square colored message unit blocks for computer systems identification and arranged without gaps according to a predetermined rule. The hidden codes are located in the colored message unit blocks, wherein the chrominance of the hidden codes is different from the chrominance of the colored message unit blocks to achieve the objective of anti-counterfeiting and hidden, thereby ensuring the colored message unit blocks that are not easy to be discovered and achieves a higher anti-counterfeiting and hidden function.
摘要:
A printed media product, such as a trading card, that has a substrate and an encoded data element applied to a surface of the substrate containing information. The encoded data element includes first, second, and third data layers with first, second, and third patterns of encoded, colored dots defined by a binary encoding scheme. The dots of the first, second, and third layers are different colors separately resolvable by a scanner with decoding software. The colors of the dots are cyan, yellow, and magenta, and the layers are printed so that the dots overlap. The binary encoding scheme includes a two dimensional run length limited code. The printed media product includes a graphics element that can be interpreted by a human user, and typically, the information encoded in the encoded data element layers is related to the information in the graphics element.

A technology to measure the position of a distant mark object and denote an automatic recognition data by the object. A light-emitting device includes an R (red) light, a G (green) light, and a B (blue) light emitters, and a control device for controlling their light-up states. The light-emitting device is affixed to the mark object and made to emit the lights by a predetermined light-emitting pattern. The light-emitting pattern forms a time-change optical recognition code denoting a desired data by change of the colors along the time axis. This optical recognition code is accomplished with a small area of space. Further, by photographing the light-emitting device with a CCD camera and the like, it is possible to recognize the position of the light-emitting device, that is, the position of the mark object. By carrying out this behavior continuously, it is possible to trace the movement of the mark object.

In some aspects, a colored coded analyte sensor is provided. The analyte sensor has a body and a plurality of machine-readable colored codes associated with the body. The colored codes may contain red, green, and blue hues, which are discernable into coded information. The coded information may include the analyte sensor model, analyte sensor calibration constant, expiration or manufacture date of the analyte sensor, analyte sensor counterfeiting codes, warnings, messages to the user, etc. Colored code reading systems, apparatus and methods for reading such color-coded information associated with the analyte sensor are provided, as are numerous other aspects.
摘要:
A method for identifying counterfeit cards and supports that can be used in such method. Such supports may be made of materials such as paper, cardboard, plastics and others. The creation of interference wave patterns generated starting from the interaction between an electromagnetic emitting source and particles installed in the cards or support, for example: by a printing processes. The so produced particle interactions (involving photons and electrons) provides complex interference maps in which constituent variables define wave junction conditions characteristic of the interaction between each INFORMATION BLOCK of particles The BLOCKS are created/built in accordance to those variables' statements, and located at different points in the support. To be approved as a valid Data point, the wave function present at each of these Points should match those stored in an extremely complex Data Matrix.

A viewing device is used with coded data on a surface. The device includes a sensor arrangement for sensing the coded data when the device is placed on the surface, and a processor in signal communication with the sensor arrangement. The processor is configured to decode the coded data. Also included is a transceiver for transmitting the decoded data to a computer system, and to subsequently receive a file pre-associated with the decoded data from the computer system. The device also includes a display configured to display the received file to a user.
