    • A method and system for generating and printing an indicium (I), such as a postal indicium, on an object (E) such as a mail piece. Other printed material, such as an address block (A), on the object (E) is scanned, and the scanned image is processed to abstract characterizing information descriptive of the other printed material. The characterizing information can be text-based or image-based. The characterizing information is combined with other information, such as postal information, and the combined information is then cryptographically authenticated with a digital signature or the like. An indicium (I) representative of the authenticated information is then printed on the object. The object's relationship to the indicium (I) can be verified by regenerating the characterizing information from the other printed material and comparing the regenerated characterizing information with characterizing information recovered from the indicium (I).
    • 用于在诸如邮件的对象(E)上生成和打印诸如邮戳的标记(I)的方法和系统。 扫描对象(E)上的其他打印材料(例如地址块(A)),并处理扫描图像以抽象描述其他打印材料的特征信息。 特征信息可以是基于文本或基于图像的。 特征信息与诸如邮政信息的其他信息组合,然后利用数字签名等对组合的信息进行密码认证。 然后将表示认证信息的标记(I)印在对象上。 可以通过从其他印刷材料再生表征信息并将再生的特征信息与从标记(I)中回收的特征信息进行比较来验证对象与标记(I)的关系。

    • A method and system for characterizing blocks of printed material. A digital image of printed material, such as an address block, on an object is obtained, and the image is processed to abstract characterizing information descriptive aspects of the other printed material. The characterizing information is combined with other information, such as postal information and the combined information is then cryptographically authenticated with a digital signature or the like. An indicium representative of the authenticated information is then printed on the object. The object's relationship to the indicium can be verified by regenerating the characterizing information from the other printed material and comparing the regenerated characterizing information with characterizing information recovered from the indicium. Thus, copies of the indicium cannot easily be used, without detection, on other objects which do not include the other printed material. A combination of algorithms is selected from a predetermined group of characterizing algorithms by determining an estimate for the robustness of each algorithm and selecting a combination having high overall robustness.
    • 用于表征印刷材料块的方法和系统。 获得对象上的诸如地址块的打印材料的数字图像,并且处理该图像以抽象其他印刷材料的特征信息描述方面。 特征信息与诸如邮政信息的其他信息组合,然后使用数字签名等对组合的信息进行密码认证。 然后将经验证的信息的标记代表印在对象上。 可以通过从其他印刷材料再生表征信息并将再生的特征信息与从标记中回收的特征信息进行比较来验证对象与标记的关系。 因此,在不包括其他印刷材料的其他物体上,标签的副本不能容易地被使用,无需检测。 通过确定每个算法的鲁棒性的估计并选择具有高整体鲁棒性的组合,从预定的一组特征算法中选择算法的组合。

    • A method and system for selecting a characterising algorithm to be used to characterize blocks of printed material.

Thus copies of the indicium cannot easily be used, without detection, on other objects which do not include the other printed material, A particular algorithm is selected from a predetermined group of characterizing algorithms by determining an estimate for the robustness of each algorithm with respect to small changes in the image caused by the printing and scanning process or by defacing of the printed address by blots or the like.
