摘要:
This invention relates to a cellular telecommunications systems that utilizes the telephone number the cellular telephone is calling, with the number of telephone calls placed on that cellular telephone, i.e., call count and a seed number to create a digital certificate of the data. The digital certificate is used to make it more difficult to make unauthorized cellular telephone calls. The seed number may be changed after a predetermined number of calls has been made, i.e. one hundred, one thousand, etc. Thus, the transmission of seed numbers between data centers would be substantially reduced.

A cost-effective motion control system communication architecture is provided that supports a centralized control node, distributed control nodes, and smart I/O peripheral control nodes. Networks designed using this architecture, which employs a serial bus, may be readily modified or expanded. The architecture supports both real-time highly periodic communications and event-driven peer-to-peer communications.

A method of paying for postage stamps, that involves the generation of a plurality of postage stamps, wherein each of the stamps has a unique identification code; and the debiting of an account for the generation of the plurality of stamps when a carrier processes one of the plurality of stamps.

A system and method for processing refund requests in a postage system is described. In one configuration, each mail piece includes a tracking code. The refund system monitors the tracking codes as mail pieces are processed in the mail stream. A user enters a refund request for a particular mail piece that is identified by a unique tracking code. The refund system then interrogates a tracking code database to determine if the mail piece was observed in the mail stream. The system then continues to periodically interrogate the tracking code database over a test period of a week to determine if the mail piece was observed in the mail stream. If the mail piece is not observed within the test period, a refund is processed. The system continues to interrogate the tracking code database for a year after the refund is processed to ensure that fraud is not committed.

A method of operating a check processing system includes scanning a check on a first occasion to generate a first image of the check. The first image is transmitted to a financial institution. The check is scanned on a second occasion later than the first occasion to generate a second image of the check. The second image of the check is transmitted to the financial institution. The second image of the check is examined to determine whether the check was cancelled prior to the second occasion.
摘要:
A mail piece verification system for processing mail pieces having associated therewith respective mail piece data. The system includes a plurality of postage metering systems for preparing mail pieces, a plurality of mail processing centers for receiving mail pieces and obtaining the respective mail piece data and a data center means in operative communication with the plurality of postage metering systems and the plurality of mail processing centers, the data center means including a plurality of account files corresponding to the plurality of postage metering systems. The data center means stores reset data in each of the plurality of account files representative of reset activity associated with the plurality of postage metering systems, respectively, receives respective mail piece data corresponding to the mail pieces from the plurality of mail processing centers, uses the respective mail piece data, storing empirical data in each of the plurality of account files representative of mailing activity associated with the plurality of postage metering systems, respectively, and conducts a forensic accounting analysis of the empirical data and the reset data associated with a selected postage metering system.
摘要:
A method and system that increases the throughput of a mailing machine by continuously computing indicia prior to and during mail processing is provided. The indicia generation process is divided into two distinct parts, cryptographic calculation and funds committal/printing. Indicium data are continuously computed, asynchronously with the printing of the indicia, and stored in a buffer until needed. This enables several indicium data to be computed and stored prior to processing of a mail piece by the mailing machine. Prior to printing an indicium on a mail piece, the funds for the indicium are accounted for by updating the registers of the mailing machine. Since a number of indicium data may be pre-computed prior to the start of processing the mail through the mailing machine, the throughput of the mailing machine can be increased.
摘要:
A signature scheme is provided in which a message is divided in to a first portion which is hidden and is recovered during verification, and a second portion which is visible and is required as input to the verification algorithm. A first signature component is generated by encrypting the first portion alone. An intermediate component is formed by combining the first component and the visible portion and cryptographically hashing them. A second signature component is then formed using the intermediate component and the signature comprises the first and second components with the visible portion. A verification of the signature combines a first component derived only from the hidden portion of the message with the visible portion and produces a hash of the combination. The computed hash is used together with publicly available information to generate a bit string corresponding to the hidden portion. If the required redundancy is present the signature is accepted and the message reconstructed from the recovered bit string and the visible portion.

A method and system for thermal printing of secure documents. A contact thermal printing system includes: a) thermal print head having at least one heater element; and b) a thermal printer controller. The printer controller is programmed to: 1) move the print head in a predetermined pattern while the print head is in contact with a top coating of a thermal print medium; 2) overdrive the heater element during predetermined parts of the pattern to a temperature sufficient to soften or melt the top coating, thereby forming a pattern of striations in the top coating; and 3) control the heater element to print at least part of an image on the medium. The contact surface of the print head can have a specific pattern of features for forming the striations, whereby a pattern of striations formed can encode information both in the direction of the motion of the print head and transversely to the direction of motion. The pattern of striations can form a bar code. The image can be a postal indicium printed on a document which is a mail piece, or other documents having value, such as tax stamps and tickets, can be printed.
摘要:
A postage metering system includes a plurality of computers operatively connected as part of a computer network and operating as client computers on the computer network. At least one postal security device (PSD) is coupled to at least one of the client computers (local client computer). The PSD includes unique identification the ability to store postal value and generate digital signatures. The client computers function as a postage metering network wherein a client computer other than the local client computer (remote client computer) requests evidence of postage payment from the PSD for concluding a postage metering transaction. The local client computer functions as a meter server and the remote client computer functions as a meter client on the postage metering network. The remote client computer initiates a postage metering transaction in the PSD by sending a request for evidence of postage payment to the local client computer. The local client computer sends the request for the evidence of postage payment to the PSD, receives transaction information from the PSD and sends the evidence of payment to the remote client computer for subsequent printing.
