摘要:
A printing system for printing both secure value documents and non-secure documents while ensuring that fraudulent copies of secure value documents printed by the printing system can be detected is provided. The printing system determines if the source is a secure or non-secure source. If the source of the image is a secure source, it will print the image, including any graphic security features. If the source is a non-secure source, before printing the image a filter is applied to the image data to remove any graphic security features included in the received image and/or the printing system will not add any graphic security features to the received image to ensure that the printed image will not contain any copy detection graphic security features.

摘要:
The present invention includes apparatus and methods for printing and verifying postage stamps on demand via a personal postage stamp printer. The indicium by which the stamp is printed includes a color stripe and a data field including authentication data that corresponds to the color stripe. To authenticate the stamp, the authentication data in the data field is read and compared with authentication data extracted from the color stripe.
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 that enables the recipient to receive notification of the letters, flats and/or packages (mail) that the recipient is going to receive prior to the delivery of the mail. The recipient is then able to inform a post or courier, e.g., Federal Express®, Airborne®, United Parcel Service®, DHL®, etc., of the manner in which the recipient would like the mail delivered if the sender elects to permit the recipient to divert the mail. The post and courier hereinafter will be referred to as “carrier”. For instance, the recipient may want the mail physically delivered to their house faster or slower, or the mail physically redirected to the recipient's temporary address, or physically delivered to the recipient's agent, or physically delivered to the recipient's attorney, or physically returned to the mailer, or have the carrier open the physical mail and have the post e-mail or fax the contents of the envelope to the recipient and/or parties designated by the recipient.
摘要:
A method for assigning unique printer resolutions or signatures, i.e., a unique number of dots per inch, to a class, or models of printers or lines of postage meters. The number of dots per inch or resolution may be specified within a image on a document or within a postal indicia and later checked to determine if the image on document or the postal indicia has the correct resolution. The foregoing would be able to detect an image or postal indicia that was scanned into a computer and printed with a printer that did not have the number of dots per inch specified in the image or postal indicia.
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.
