    • The present invention provides a method for verifying an unreadable information-based indium that has been generated by a postal security device (PSD) for information-based indium comprising a 2-D bar code, certain human-readable information, a digital signature and a certificate. The method comprises the steps of attempting to read the 2-D bar code using sophisticated digital image processing when the 2-D bar code is not readable; and continuing normal processing when the 2-D bar code is readable with the sophisticated digital image processing. When the 2-D bar code is not readable two independent processes are used to determine the indicium certificate. A first process includes reading human readable information by optical character recognition using context, syntax, and redundancy in the human readable information to obtain a PSD-ID; and using the PSD-ID to look up in a certificate database a certificate corresponding to the information-based indicium. A second process includes interpreting partial bar code data and extracting a “best guess” of the certificate and searching the certificate database for the closest matching certificate. The method further comprises merging data obtained from the two processes and attempting to reconstruct bar code data from the merged data. If the merged data is sufficient, an attempt is made to verify the digital signature obtained from the merged data. If the signature is verified, normal processing is resumed. If the merged data is insufficient or if the signature is not verified, a suspect mailpiece record is created.
    • 本发明提供了一种用于验证由用于基于信息的铟的邮政安全设备(PSD)生成的不可读信息的铟的方法,其包括二维条形码,某些人类可读信息,数字签名和 证书。 该方法包括以下步骤:当2-D条形码不可读时,尝试使用复杂的数字图像处理来读取2-D条形码; 并且当复杂的数字图像处理可读取2-D条形码时,继续正常处理。 当二维条形码不可读时,两个独立进程用于确定标记证书。 第一过程包括通过使用人类可读信息中的上下文,语法和冗余的光学字符识别来读取人类可读信息以获得PSD-ID; 并使用PSD-ID在证书数据库中查找与基于信息的标记相对应的证书。 第二个过程包括解释部分条形码数据并提取证书的“最佳猜测”,并在证书数据库中搜索最接近的匹配证书。 该方法还包括合并从两个处理获得的数据,并尝试从合并的数据重建条形码数据。 如果合并的数据足够,则尝试验证从合并的数据中获得的数字签名。 如果签名被验证,则恢复正常处理。 如果合并的数据不足或签名未被验证,则创建可疑的邮件记录。

    • An electronic voting system includes a vote security device (VSD), a user interface for presenting a ballot to a voter, and an audit trail printer operatively coupled to the VSD. The printer prints an audit trail ballot only in response to verifying encrypted and/or digitally signed messages received from the VSD that indicates the voter's ballot selections. The printer is structured to allow the voter to view but not access the audit trail ballot. The voter is able to accept or reject the audit trail ballot using the user interface. If the ballot is rejected, the VSD causes the printer to print a rejection indicator on the ballot, and if the voter accepts the ballot, the VSD causes the printer to print an acceptance indicator on the ballot. A digitally signed record of the voter's ballot selections is generated and stored.
    • 电子投票系统包括投票安全装置(VSD),用于向投票者呈现投票的用户界面以及可操作地耦合到VSD的审计跟踪打印机。 打印机仅打印审核跟踪投票,以响应验证从VSD收到的加密和/或数字签名消息,指示投票人的投票选择。 打印机的结构允许投票者查看但不能访问审核跟踪投票。 选民能够使用用户界面接受或拒绝审计跟踪投票。 如果投票被拒绝,则VSD会使打印机在投票上打印拒收指示符,如果投票人接受投票,则VSD会使打印机在投票上打印验收指示符。 生成并存储选民投票选择的数字签名记录。
