摘要： A method of printing a document includes generating commands in a computing device that include: (i) commands for printing based on document data, and (ii) an identification of a determined portion of the document data that is to be used in generating a printed copy detection pattern. The method further includes sending the printer control commands to an intermediate electronic device that stores a key, generating copy detection pattern data using the determined portion of the document data and the cryptographic key, and generating modified printer control commands that include commands for printing a first document portion based on the document data and a second document portion including the printed copy detection pattern based on the copy detection pattern data. Finally, the modified printer control commands are sent to a printing device. Also, a system is provided for implementing the method.

摘要： Methods and systems for verification of indicia that do not require key management systems, and in which revocation of key pairs is easily performed without adding costs to the verification process are provided. Indicia are generated and authenticated utilizing an identity-based encryption (IBE) scheme. A key generating authority generates a private key for a PSD, distributes the private key securely to the PSD, and provides public information for use by a verification service when verifying cryptographic digital signatures generated with the private key. The corresponding public key is a string consisting of PSD information that is provided as part of the indicium. The verification service can verify the signature of each indicium by obtaining the public key string from the indicium, and utilizing the key generating authority's public information.

摘要： A method for printing secure source images of the type that contain specific critical elements and non-secure images on a single printer includes determining the origin of an image (secure source or non-secure source). If the image to be printed is from the non-secure source, a determination is made if the image contains the specific critical elements of the type contained in secure source images. Printing of the image from the non-secure source is disabled if the image contains specific critical elements of the type contained in secure source images. Printing of the image from a non-secure source is enabled if the image does not contain specific critical elements of the type contained in the secure image. The determination if the non-secure source image contains the specific critical elements of the type contained in secure source images can be made after printing has commenced of the non-secure image.

摘要： Methods and systems that provide privacy of signatures on envelopes containing ballots are provided. The envelope for returning ballots includes a flap with a window that aligns with a signature area on the envelope. The window appears opaque under normal lighting conditions, but appears transparent when illuminated with light having a predetermined wavelength. A movable signature stub is positioned on top of the signature area. The voter signs the back of the envelope on the signature stub, thereby imprinting a signature on the signature area by transferring a material from the signature stub to the signature area, and moves the signature stub. The flap of the envelope is then sealed, thereby covering the voter's signature in the signature area with the window of the envelope flap. To read the signature, light having the predetermined wavelength can be directed onto the window, thereby rendering the window transparent and the signature visible.

摘要： A closed loop postage metering system includes networked meters that provide mailers and/or recipients the capability to request additional or modified services during processing of a mail piece by a carrier. The networked meter allows the Post to charge the mailer, or even the recipient for these services or to provide them with a refund or credit. The services can include changing the processing of the mail piece. Further, the closed loop postage metering system enables more precise methods of paying for services when multiple carriers handle a mail piece. A special case of such multiple carriers handling is the handling of international mail.

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。

摘要： A method for assigning keys to a plurality of devices in a public key cryptographic system includes generating a set of more than one master private keys; calculating for each master private key a corresponding master public key; installing in each of the plurality of devices a corresponding device private key derived as a linear combination of at least two of the master private keys from the set of master private keys whereby knowledge of the corresponding device private key installed in any one of the plurality of devices is not sufficient to determine the corresponding device private key of any other of the plurality of devices. A device public key can be calculated as a corresponding combination of the master public keys.

摘要： A secure and reliable method for verifying in the host system that the expected PSD is coupled to the host system includes generating a random number in the host system and encrypting the random number with a PSD state identification number. The encrypted random number is then sent to the PSD. The PSD decrypts the encrypted random number received using the PSD state identification number and sends the decrypted random number to the host system. The host system compares the decrypted random number received from the PSD to the random number generated in the host system. If they are the same, the host system has verified the expected PSD and has also verified that the PSD has not completed any transactions apart from the host system. A method for verifying that the expected host is coupled to the PSD mirrors the method for verifying the expected PSD.

摘要： A postage evidencing system including a plurality of domains for partitioning a population of postage meters according to an operating characteristic, a data center, a postage meter in operative communication with the data center and a printer in operative communication with the postage meter. The postage meter is initialized to operate in a particular domain while the printer is capable of operating in each of the plurality of domains. To update or enable a domain in the printer, the postage meter transmits an indication of the particular domain to the data center. Then, the data center encrypts the indication and transmits the indication to the postage meter which in turn forwards the encrypted indication to the printer. The printer decrypts the encrypted indication and using the indication enables a respective domain in the printer corresponding to the particular domain of the postage meter. A method for updating domains in a postage evidencing system is also provided.

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.
