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.

Abstract: A contaminant detection system for mail is provided. A tray of mailpieces is transported along a transport path into a chamber that has a negative pressure maintained by a vacuum system. The tray of mail enters the chamber and is quickly decelerated, such as, for example, by hitting a stop. The quick deceleration compresses the mailpieces in the tray, thereby ejecting air, dust and other particles from the mailpieces into the surrounding environment inside of the chamber. The vacuum system draws the ejected air, dust and other particles into a sampling system that monitors for the presence of a possible biohazard. If any type of contaminant is found in the ejected air, dust and other particles, the tray can be held for further investigation of the mailpieces. If no contaminants are detected, the tray is accepted and the mailpieces are further processed.

Abstract: A method for certifying the public key of a digital postage meter using a public key encryption system by a certifying authority. A certifying station and a user station, or a digital postage meter, exchange information and the user station and downloads, or the meter derives, a public key from the exchanged information. The certifying station also publishes related information and its public key. A third party can derive the public key corresponding to the meter's private key by operating on the published information with the certifying station public key.

Abstract: A system and corresponding method for detecting duplicate indicia on mailpieces.

Abstract: A business reply mail piece and associated processing system that allows information contained within business reply mail to be scanned and interpreted before the business reply mail reaches its ultimate destination is provided. A machine-readable block of control information that instructs computer-driven actuators what to do with the business reply mail document itself, its digital image (or parts of thereof) and the data elements contained in the document, based on selections made by the recipient, is provided on the business reply mail piece. A scanner module scans the business reply mail piece to read the selection made by the recipient and the corresponding instructions from the block of control information. A control module interprets the data to provide instructions for the processing of the business reply mail piece based on the recipient's selection.

Abstract: A method and system for reading a two-dimensional barcode symbol on a mailpiece. The barcode symbol may be distorted during the printing process or the image acquiring process, rendering it difficult to recognize by a conventional template matching method. Typically, a two-dimensional barcode symbol is composed on a two-dimensional array of visually contrasting blocks. Any group of four adjacent blocks sharing a common corner may form an identifiable pattern. These patterns can be used as internal landmarks. When the barcode symbol is distorted, the distances between the internal landmarks change accordingly. Using an Lp-norm algorithm to measure the distances in the transform domain, distortion can thus be determined and the global geometry of the barcode symbol restored based on the distance measurements.

Abstract: A method for communicating a re-keying message from a postage meter to a registration authority includes the steps of determining at the postage meter that a current key needs to be replaced with a new key; generating in the postage meter the new key; creating in the postage meter the re-keying message, the re-keying message including at least a device identifier and the new key; using the postage meter for printing the re-keying message in a machine-readable form on a recording medium; and mailing the recording medium to the registration authority.

Abstract: A method and system that protects against a parallel printing attack is provided. During initialization of a printer and a meter, the printer provides the meter with an identification number. The identification number can be a serial number or the like, or a random number generated by the printer. The meter includes the identification number in each indicium message sent to the printer and optionally signs the message. When the printer receives an indicium message, it will compare the identification number in the indicium message to its own identification number. If the identification number is identical, the printer will print the indicium. If the identification number is not identical or the signature does not verify, the printer will not print the indicium. Thus, only the printer connected to the meter during initialization of the system will be able to print indicia generated during that session.

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 and system for validating the creation and submission of absentee ballots is provided. An authentication/validation mark is generated and printed on an absentee ballot and/or the envelope that contains the absentee ballot. The authentication/validation marks include information such as, for example, the date and time of printing, an identification and location of the vote validator that generated and printed the mark, a unique identifier of the mark, and a digital signature of the authentication/validation data. Upon receipt of the absentee ballot by election officials, the authentication/validation marks printed on the absentee ballot and/or envelope containing the ballot can be verified by authenticating the digital signature and verifying the validity of the data in the mark. If the mark is verified, the authenticity and creation/submission dates of the absentee ballot are guaranteed and the absentee ballot can be accepted as a valid absentee ballot for election purposes.

Abstract: A method for printing a large invisible luminescent bar code on a mail piece addresses the problem of obscuration of modules by printed text such as the address. The bar code is printed large enough so that the line width of the characters is substantially less than the module size of the bar code components. Overprinting does not then completely obscure any module and so the bar code is still readable. The readability is especially enhanced by the high contrast of the luminescent image. When a fluorescent bar code is viewed under UV illumination, the bar code emits fluorescence in the areas of printed modules without text overprinted. Because the modules are wider than the text line width, the text does not completely obscure any module. The contrast of the bar code is reversed in fluorescence—that is, printed areas emit light.

Abstract: A weight estimating system for estimating the weight of a mailpiece and a postage metering system including such a weight estimating system. The weight estimating system includes a measuring system, a diverter mechanism and a microprocessor system. The measuring system includes a transport, a first plurality of detectors for measuring the dimensions of the mailpiece and a second plurality of detectors for measuring values of other characteristics of the mailpiece which are indicative of the presence of non-paper materials in the mailpiece as the mailpiece is transported. The microprocessor is responsive to the second detectors to determine if non-paper materials are included in the mailpiece and, if not, determines the volume from the dimensional measurements and estimates the weight as the product of the volume and a density for paper output an appropriate postage amount to the meter and the mailpiece to the printer.

Abstract: A method that enables a receiver or receiver's agent (hereinafter “recipient”) to obtain 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. The post and courier, hereinafter, will be referred to as “carrier”. For instance, the recipient may want 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.

Abstract: A method for certifying the public key of a user wishing to communicate using a public key encryption system by a plurality of certifying authorities. A plurality of certifying stations and a user station exchange information and the user station derives a public key from the exchanged information. The certifying stations also publish related information and their public keys. A third party can derive the public key corresponding to the user's private key by operating on the published information with a summation of the certifying station keys.

Abstract: 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.

Abstract: A method and system for generating messages from which it can be verified that a variable does not exceed a predetermined limit. The message can be a postal indicium. A message originator, which can be a postage metering system, receives a message in the form R−k(T), where R is a trapdoor function, K is an integer equal to the limit, and T is a plain text, from a data processing center which maintains the inverse function R−1 in secrecy. The message originator computes Sm=Rm(R−k(T), where m is a current value of the variable, and incorporates Sm into the message. A verifier verifies that m<K by confirming that Rk−m(Sm)=T. The verifier cannot compute Rk−m(Sm) for m<K since it does not have R−1. For the same reason the originator cannot compute R−k′(T), k′>K, from R−k(T).

Abstract: Radio frequency identification tags are placed on mail contained in trays or tubs to locate and reroute mail that is misdirected, i.e., being routed to the incorrect destination. The method involves the carrier reading the identifying information contained in the radio frequency identification tags on each mail piece while each mail piece is in the trays or tubs and removing one or more mail pieces in the tray or tub that are to be routed differently than that routing information contained on the outside of the trays or tubs.
