Abstract: A system for facilitating a transaction between a first party and a second party is controlled by a trusted third party system and is programmed to carry out the method by receiving the first party's instructions for fulfilling at least a part of the first party's obligations in said transaction. The system communicates with the second party and provides the second party with perceptible assurance that the second party is in communication with a trusted third party system through the system. The system transmits information to the second party to provide assurance that the first party's instructions have been or will be fulfilled. Thus trust in the third party is transferred to the first party and the second party can trust that the first party's obligations have been or will be fulfilled.

Abstract: A method of printing a two-dimensional barcode by tilting the print head, which results in tilted barcode, and methods of detecting various types of attempts to forge the tilted barcode including: (i) a low level forgery that consists of a simple scan and reprint of the barcode, (ii) a low level forgery that consists of a reproduction (i.e., a read and regeneration) and subsequent printing of the barcode using a printer with a non-tilted print head by a fraudster that is not aware of the tilt in the original barcode, and (iii) a higher level forgery by a fraudster that is aware of the tilt in the original barcode and that digitally tilts/shears an image of the barcode and prints the digitally tilted/sheared image using a printer with a non-tilted print head in an effort to mimic the tilt present in the legitimate barcode.

Abstract: A method and system that protects against a replay attack in a closed system postage meter is provided. “Freshness” data is included along with each indicium message sent from the meter to the printer, thereby enabling the printer to detect “stale” indicium data, i.e., indicium data that was previously generated and is being replayed, and prohibit the printing of duplicate indicia. The freshness data includes a random nonce generated by the printer during initialization along with sequence data that the printer can verify against sequence data from the previous printed indicium. If in the current indicium message the nonce is different or the current sequence data is not greater than or equal to the sequence data from the previous printed indicium, indicating the current indicium data may have been previously generated and is a replay, the printer will not print the current indicium data.

Abstract: 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.

Abstract: A mailing list is created including destination addresses for mailpieces to be submitted to a carrier service for delivery. A unique mailpiece identifier associated with mailpieces on the mailing list is generated by the carrier or other trusted third party. The unique mailpiece identifier is printed on the mailpiece with which it is associated. The mailpieces with the printed unique identifier are submitted to the carrier service. The carrier service obtains the printed unique identifier from the mailpiece. The obtained unique identifier from each said mailpiece is utilized to verify that data associated with the mailpiece has been processed by the carrier or trusted third party. When the unique number has been obtained from the mailpieces, the carrier service, if desired, may note this fact in the carrier records to prevent reuse of the unique identifier.

Abstract: A mailing machine that optimizes throughput by reducing the amount of time necessary for the PSD to generate the digital signature and indicium for each mail piece is provided. The debit operation performed by the PSD, i.e., adjusting the PSD registers, is separated into three different sections, a pre-debit operation, a perform debit operation, and a complete debit operation. In addition, the calculation of the digital signature can optionally be pre-computed, or, alternatively, computed in stages, i.e., partial signature calculation. Utilizing this granularity, the cryptographic operations associated with generating the digital signature can be shifted between the three debit operations such that the execution time of the time critical portion of the debit operation (perform debit) can be optimized to meet the performance requirements of the mailing machine in which the PSD is deployed.

Abstract: 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.

Abstract: Methods and systems that prevent completion of postdated financial transactions until the specified future date is provided. A portion of the information necessary to complete a financial transaction is encrypted utilizing an identity-based encryption (IBE) scheme. The encryption key used to encrypt the information is associated with the date on which the transaction is authorized to be completed. The encrypted information is provided to the payee. The issuing bank provides a daily decryption key that allows decryption of information encrypted using the key associated with the corresponding date. Thus, only when the maturity date of the transaction has arrived will the payee or depositing bank be able to obtain the decryption key that will decrypt the encrypted information necessary to complete the transaction. Since the encrypted information can not be decrypted until the date associated with the encryption key, the financial transaction can not be completed until such date.

Abstract: A method and system for creating and maintaining databases of user profiles and value ratings for information sources, and for generating lists of information sources having high estimated values. User controlled systems for accessing information sources through the internet or other networks are monitored by a server. The server updates the user profiles and computes value ratings associated with the user profiles for various information sources in accordance with monitored information. Estimated values for information sources to a particular user are obtained as a function of the value ratings associated with profiles of other users and the degree of similarity between the particular user's current profile and other user profiles. Previous profiles are not deleted when updated but are retained and treated substantially as other profiles in computing value estimates. Information sources can be other users.
