摘要： A method and system for authenticating an item by using a security marking. The security marking is provided on the item with an OVD ink capable of absorbing light in a visible wavelength range to appear visibly black and producing a red fluorescent emission under ultraviolet excitation. Under visible light illumination and ultraviolet excitation, a visible image and a fluorescent image are obtained from the security marking using image scanners. The images are compared to find a substantial match with each other. The security marking can be a postage indicium, a barcode, a symbol, a message or an image. The item to be authenticated can be a mailpiece, a banknote, a tag, a ticket, a document, an identification card, or the like.

摘要： Improvements are provided in processing of documents to increase their security and/or decrease the complexity of testing for authenticity. Methods for printing documents with security markings and methods and apparatus for authenticating documents are described. In one aspect a document is printed with a security marking comprised of an image printed in at least two image segments. The image can be printed with an ink capable of forming images which are visible both to viewing under white light and as fluorescent images when irradiated with ultraviolet light, the segments having features of different sizes. The relative sizes of the two image segments will provide a detectable difference in fluorescent image sharpness. The apparatus provides means, all of which are simple and easily available for carrying out the methods.

摘要： A method for producing a background image representing data. The background image is created by; producing a first encoding of data into a first binary array; producing a second encoding of the data into a second binary array; representing the first binary array as a first set of modules of a first size of n×n pixels wherein each pixel is either white or black and every pixel in the module is identical to every other picture in the module on nodes of a first lattice, representing the second binary array as a first set of modules of a second size, of m×m wherein each pixel is either white or black and every pixel in the module is identical to every other pixel in the module, which is smaller than the first size on nodes of a second lattice, combining the first and second sets of modules; and printing the first and second sets of modules.

摘要： A method for detecting a copy of a composite image that includes a first image and a second image that has information embedded in the second image that will change in appearance when the first and second images are scanned or photocopied. The foregoing is accomplished by scanning the first and second images, and detecting a change in appearance of the second image that indicates the first and second images were scanned or photocopied.

摘要： A method of printing modules for a two dimensional barcode that includes printing a pixel at a plurality of the pixel locations included in the inner portion of the darkened module, and printing a pixel at less than all of the pixel locations of the outer boundary of the darkened module. Various embodiments are contemplated, such as, without limitation, methods that print darkened modules having four light corners, three light corners, two light corners, one light corner, and/or one light edge. Also, a method of printing a two dimensional barcode having a finder pattern wherein the inner edge of the finder pattern is light, meaning that is does not include any printed pixels at the pixel locations along the inner edge.

摘要： The disclosure describes an authentication system and related methods for authenticating printed objects. The system uses an information-based metric along with one or more print quality metrics to provide accurate detection or classification of a counterfeit printed object. The print quality metric evaluates attributes of a subject image associated with the original printer, ink or paper to detect degradation of those operations due to copying operations like an image scanning and halftone printing subsequent to the original printing of the object. The information-based metric measures message symbol errors in an optically readable code, such as a digital watermark.

摘要： A method for producing a metered tape and an indicium on a meter tape comprising determining a location on the meter tape where the indicium is to be printed, generating the indicium with information related to the location incorporated therein, and printing the indicium on the meter tape at the location. A method of authenticating an indicium printed on a meter tape comprising retrieving information stored within the indicium, the information identifying a first location where the indicium is supposed to be positioned relative to the meter tape, detecting a spatial indicator identifying a second location where the indicium is actually positioned relative to the meter tape, and comparing the first location to the second location. Mail metering and authenticating systems for implementing the methods are also disclosed.
