    摘要: 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 or document or the postal indicia has the correct resolution. The foregoing is accomplished by specifying that the image on the substrate will be printed with n plus m dots per inch; rotating a ink jet head having n nozzles per inch about a axis parallel to a substrate by an angle &thgr; so that the ink jet head will produce an image on the substrate having (n/cos &thgr;) dots per inch; storing in a data center that the specified image will be printed with (n/cos &thgr;) dots per inch; analyzing the image to determine if the image has (n/cos &thgr;) dots per inch; and comparing the number of dots per inch in the analyzed image with the number of dots per inch stored for the specified image to determine if they have the same number of dots per inch.

    摘要: A method and system for processing mail pieces or substrates containing data printed thereon involves scanning a mail piece or substrate and obtaining information concerning the printed data. The information is processed to determine if the data is readable. Non readable data information is processed to determine if the non readable data is due to predetermined causes of a first type or predetermined causes of a second type. Substrates or mail pieces with non readable data due to predetermined causes of the first type may be processed in a first manner and processing substrates or mail pieces with non readable data due to predetermined causes of the second type may be processed in a second manner. The printing may be optical character recognizable, bar code of any type or any other form of printed data.

    摘要: A method and system for securing the communication link between the accounting device and printer of a metering system by authenticating the data being sent via the link utilizing a Nonlinear Feedback Shift Register (NLFSR) based system is provided. A NLFSR is provided in each of the accounting unit and printing unit of a metering system. The NLFSR in the accounting unit is utilized to generate a message authentication code (MAC) for the image data being sent from the accounting unit to the printing unit. The printing unit generates a corresponding MAC for the received image data using the NLFSR in the printing unit. The MAC generated by the printing unit is compared with the MAC generated by the accounting unit. If the MACs are similar, the image data is accepted as authentic and the printing unit will print the image corresponding to the image data.

    摘要: An opt-in email system in which a recipient that has opted in to an email list can recognize and trust that an email has actually come from a desired sender. When a recipient desires to opt-in to an e-mail list, the recipient is sent to a trusted third party certification service that generates a certificate associated with a key pair. A key is maintained at the sender's location by a secure cryptographic device that can verify the certificate and create a signature, using a key of the key pair, for messages intended for the recipient. When a message intended for the recipient is received from the sender, the signature will be verified based on the status of the certificate and the corresponding key of the key pair. If the signature does not verify, it indicates that the recipient has not opted-in to receive emails from this sender.

    摘要: A method of printing an image having a graphic security element included therein includes receiving main image data representing a main image, receiving graphic security element data representing a graphic security element to be included in the main image, receiving a request to print the main image, responsive to receiving the request to print the main image, determining particular pixels of the main image data that are to be shifted based on the graphic security element data, and causing a plurality of ink deposits to be deposited on the print medium based on the main image data including causing the position of each of the ink deposits on the print medium that is determined to correspond to shifted pixels to be shifted relative to a normal position that would normally result from the main image data. Also, system that implements the method is provided.

    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: A printing system is provided that dynamically adjusts the method of printing an image based on the lightness or darkness of the medium upon which the image will be printed. The reflectivity of the medium upon which an image is to be printed is determined, and the way in which the image will be printed is adjusted based on the determined reflectivity of the medium. For lighter colored mediums, on which sufficient contrast will be provided, the image can be printed directly onto the medium. For darker colored mediums, on which the ink used to print the image will not provide enough contrast with respect to the medium to produce a reliably readable image, the method of printing the image is modified to ensure that sufficient contrast is always provided to produce a reliably readable image.

    摘要翻译: 提供了一种打印系统,其基于打印图像的介质的亮度或暗度来动态地调整打印图像的方法。 确定要打印图像的介质的反射率,并且基于所确定的介质的反射率来调整图像将被打印的方式。 对于要提供足够对比度的较浅色的介质,可以将图像直接打印到介质上。 对于较深色的介质,用于打印图像的墨水将不能提供相对于介质的足够的对比度以产生可靠的可读图像,因此修改打印图像的方法以确保始终提供足够的对比度以产生 可靠可读的图像。
