    • A system and method of printing value such as postage using a value meter (10) connectable to communicate with a host terminal (12) which includes a printer (24). The postage meter (10), sometimes referred to as a vault, includes a processor (14) and storage (16) and the host terminal includes a processor (22) and storage (30). The printer (24) is provided with a secure non-volatile random access storage (30) and a processor (28) and a key is stored in the non-volatile random access storage (30). The key is changed for every print cycle so that it is impossible to print unauthorized postage on the basis of possession of the key used to print the last postage. A change of key is effected by reading the key from the non-volatile random access storage (30) in the printer (24) and changing the key, such as by a pseudo-random number generator, to provide a second key. The second key is stored in the non-volatile random access storage (30) and then encrypted by an encryption scheme known to an authorized postage meter. The encrypted second key is transmitted to an authorized postage meter wherein it is decrypted pursuant to the decryption scheme known to the authorized postage meter. Print data may be securely transmitted to the host (12) and printer (24) by using the decrypted second key to convert the data to be printed. This is then sent to the printer where it is deconverted using the second key to recover the data to be printed.
    • 印刷值的系统和方法:例如,使用值计邮资(10),可连接到与主机终端(12),其包括一打印机(24)通信。 邮资计费器(10),有时被称为拱顶,包括处理器(14)和存储器(16)和主机终端包括处理器(22)和存储(30)。 打印机(24)设置有一个安全的非易失性随机存取存储器(30)和处理器(28)和一个密钥存储在非易失性随机存取存储器(30)。 关键是改变每个打印周期,因此这样做是不可能拥有用于打印负荷邮资关键的基础上擅自打印邮资。 如通过伪随机数生成器,以提供第二键:密钥的改变是通过读取来自所述非易失性随机存取存储器(30),所述键在打印机(24)和改变密钥,颜色实现。 第二密钥被存储在非易失性随机存取存储器(30),然后通过加密方案加密,以公知的给授权邮资计费器。 加密的第二个关键是在授权的邮资反式mitted到worin它是根据解密的已知授权邮资解密方案。 PrintData可以是牢固地反mitted到主机(12)和打印机(24)通过使用经解密的第二密钥对将要打印的数据转换。 这然后被发送到其被使用的第二密钥,以恢复将被打印的数据逆转换后的打印机。

    • The method for verifying mailpieces includes the steps of creating a mailpiece image having a set of data included in a postal revenue block and storing the images in a verification image file. The data from the postal revenue blocks in the verification image file are converted into corresponding data representative of the characters in the postal revenue block of the image of the mailpiece, preferably as ASCII data. The ASCII data is stored in a verification file which may be transmitted as desired. Verification of the mailpiece data can be performed at any time off-line using the corresponding data in the verification file. The conversion may be made by keying in the data or using bar code or OCR where the data is machine readable.
    • 用于验证邮件的方法包括以下步骤:创建具有包含在邮政收入块中的一组数据的邮件图像,并将该图像存储在验证图像文件中。 来自验证图像文件中的邮政收入块的数据被转换成代表邮件图像的邮政收入块中的字符的对应数据,优选地作为ASCII数据。 ASCII数据存储在可根据需要传输的验证文件中。 邮件数据的验证可以使用验证文件中的相应数据离线进行。 可以通过键入数据或使用条形码或OCR来进行转换,其中数据是机器可读的。
