    • 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.
    • 提供一种签名方案,其中消息被分成隐藏的第一部分,并且在验证期间被恢复,并且第二部分是可见的并且被要求作为验证算法的输入。 通过单独加密第一部分来产生第一签名组件。 通过组合第一组件和可见部分并对其进行密码散列来形成中间组件。 然后使用中间部件形成第二签名部件,并且签名包括具有可见部分的第一和第二部件。 签名的验证将仅从消息的隐藏部分导出的第一组件与可见部分组合,并产生组合的散列。 所计算的散列与公开可用的信息一起使用以产生对应于隐藏部分的位串。 如果存在所需的冗余,则签名被接受,并且从恢复的位串和可见部分重建消息。

    • 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.
    • 一种用于安全文件热敏打印的方法和系统。 接触式热敏打印系统包括:a)具有至少一个加热元件的热​​打印头; 和b)热敏打印机控制器。 打印机控制器被编程为:1)当打印头与热敏打印介质的顶部涂层接触时,以预定图案移动打印头; 2)在图案的预定部分期间将加热器元件过度驱动到足以软化或熔化顶部涂层的温​​度,从而在顶部涂层中形成条纹图案; 以及3)控制加热器元件以在介质上打印图像的至少一部分。 打印头的接触表面可以具有用于形成条纹的特定特征图案,由此形成的条纹图案可以在打印头的运动方向上和横向于运动方向上编码信息。 条纹图案可以形成条形码。 该图像可以是打印在作为邮件的文档上的邮政标记,或者可以打印其他具有价值的文件,例如税票和票据。

    • 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.

    • A method and system for printing an image such as a postal indicium. In accordance with the present invention a sequence of graphic data blocks is formed, the sequence forming a bitmap representative of the image. The blocks are randomly reordered to form a new sequence; and the blocks are printed in the new sequence; a printer printhead being positioned and the blocks being printed so as to print the image without substantial distortion. In one embodiment the blocks are printed in varying directions. In another embodiment the printhead moves are at varying rates of travel and prints at inversely proportional rates as the blocks are printed so as to print the image without substantial distortion. In another embodiment the printhead returns to a home position after printing the image. In another embodiment the system includes a motor responsive to a programmable controller and mechanically coupled to the printhead for positioning the printhead and the programmable controller and the motor are enclosed in a secure housing so that no signals for controlling the motor are available outside of the housing.
