    • The present invention uses an element of digital data that is created during digital postage mark (DPM) generation process from the digital image of the destination address block. The digital data is included into recoverable portion of the digital signature and imprinted on a mailpiece. During DPM verification, a representative portion of a destination address block image is retrieved in its original form from the digital signature itself. The retrieved portion of the image then can be compared with the similar digital data obtained from the scanned destination address block obtained during normal mail scanning and processing activities. If the comparison is under a predetermined threshold, then the DPM is declared authentic and the mailpiece can be processed and delivered with confidence. If, on the other hand, the threshold is not met, the DPM is declared a copy or a counterfeit of another DPM and the mailpiece can be subjected to further investigation.
    • 本发明使用从目的地址块的数字图像在数字邮戳(DPM)生成处理过程中创建的数字数据的元素。 数字数据被包括在数字签名的可恢复部分中并印在邮件上。 在DPM验证期间,从数字签名本身以原始形式检索目的地址块图像的代表部分。 然后可以将检索到的图像的部分与在正常邮件扫描和处理活动期间获得的扫描的目的地址块获得的类似数字数据进行比较。 如果比较低于预定阈值,那么DPM被声明为可信的,并且可以自信地处理和传送邮件。 另一方面,如果不符合门槛,则DPM被宣布为另一个DPM的副本或伪造,邮件可以进行进一步的调查。
