Abstract: A transaction evidencing system includes a personal computer (PC) comprising a processor, memory and hard drive, with a plurality of non-metering application programs that selectively run on the PC. An unsecured printer is operatively coupled to the PC for printing in accordance with the non-metering application programs. A portable vault card that is removably coupled to the PC is programmed to generate tokens generation and perform transaction accounting. An application interface module in the PC, which interfaces with the non-metering application programs, issues a request for digital tokens in response to requests for indicia from a non-metering application program. A secure communications module in the PC, which securely communicates with the vault card when the vault card is coupled to the PC, sends the request for digital token to the vault card and receives a digital token generated by the vault card.

Abstract: A closed system meter that secures the link between the accounting device and printer utilizing a Linear Feedback Shift Register (LFSR) based stream encryption is provided. The accounting device includes an LFSR that comprises a plurality of stages, with one or more taps that are passed through a logic gate to provide a “feedback” signal to the input of the LFSR, to generate a pseudo-random pattern output. Preferably, a Shrinking Key Generator (SKG) is utilized to further ensure privacy of the data. The output data from the accounting unit is encrypted utilizing the output from the LFSR and sent to the printing device. The printing device includes a similar LFSR, which is utilized to decrypt the output data from the accounting unit and enable printing.

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 system and method of evidencing postage payment includes a local postage printing system requesting to a remote data metering center for the generation of postage evidencing information. The request includes a postage amount to be printed on a mailpiece. The remote data metering center determines a postal origin corresponding to the request for postage evidencing information, then accounts for the postage amount in a general account corresponding to the local postage printing system and in a payment account corresponding to the determined postal origin. The remote data metering center generates postage evidencing information in response to the request. The postage evidencing information includes a digital token and the determined postal origin. The remote data metering center sends the postage evidencing information to the local postage printing system which prints the postage evidencing information and the determined postal origin on the mailpiece.

Abstract: System and method for providing confirmation relating to the distribution of a mailpiece within a mailing system includes a determination of postal data required for postage evidencing of a mailpiece originated by a mailer. The postal data is combined with other data related to value-added services desired for the mailpiece. The value-added services data includes addressing information for a return receipt to the mailer. A digital postmark which includes the postal data and the value-added services data is created. At delivery of the mailpiece, the digital postmark is read and the value-added services data is captured from the read digital postmark. A confirmation message is sent to the mailer and/or other interested third parties, in accordance with information contained in the value-added services data.
