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.
摘要翻译：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。

摘要： 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 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.

摘要： A method for removing postal funds from a postage meter provides an accounting unit of a postage meter with indicium-related information which is invalid for mailing such as invalid origin zip or date. The accounting unit generates a digital signature, which is an encrypted value of the postal funds removed from the postage meter and other postal data including the indicium-related information. The accounting unit through a Host PC sends to a data center the amount of the postal funds removed from the postage meter and the digital signature. The data center verifies that the digital signature has been generated using the indicium-related information. The meter is disabled when the digital signature cannot be verified. When the digital signature is verified a request for a refund is sent by the data center to a postal authority. An example of the indicium-related information is an invalid destination postal code or an invalid origination postal code.

摘要： This invention includes a voice response unit that communicates rapidly and directly with a system with minimum human intervention and minimizes the number of retransmissions of information due to errors. The rapid communication is achieved by knowing the question or prompt posed by the voice response unit and preparing a response which is speed dialed to the voice response unit. The voice response unit also examines an error correction code, i.e., Reed-Solomon, to determine if there is an error in the information transmitted to the voice response unit. The timing information enabled the voice response unit to determine whether or not one or more tones are missing from the transmitted information or one tone became two tones. The voice response unit determines if the information it received is correct based upon the error correction code. If, the information is incorrect the voice response unit uses the error correction code to determine and correct certain errors.

摘要： Methods and systems for providing confidentiality of communications sent via a network that is efficient, easy to implement, and does not require significant key management. The identity of each node of the routing path of a communication is encrypted utilizing an identity-based encryption scheme. This allows each node of the routing path to decrypt only those portions of the routing path necessary to send the communication to the next node. Thus, each node will only know the immediate previous node from which the communication came, and the next node to which the communication is to be sent. The remainder of the routing path of the communication, along with the original sender and intended recipient, remain confidential from any intermediate nodes in the routing path. Use of the identity-based encryption scheme removes the need for significant key management to maintain the encryption/decryption keys.
