摘要：
The document identification method comprises: a step of generating an image, a step of marking a plurality of documents to form said image on each said document with unique variations on each document, the majority of the images formed on said documents presenting a physical anti-copy characteristic satisfying a pre-defined criterion such that said characteristic of the majority of the copies that can be produced based on these images do not satisfy said pre-defined criterion, a step of characterizing said variations to form a unique imprint of the mark formed, for each said document and a step of memorizing said unique imprint. In embodiments, said image only comprises two colors.In embodiments, during the step of characterizing variations, frequency analysis is utilized.In embodiments, during the step of memorizing, the imprint is stored in a database and/or the document is marked with a mark representing the imprint affixed individually on the document.
摘要（中）：
该文件识别方法包括：生成图像的步骤，标记多个文档以在每个所述文档上形成所述图像的步骤，在每个文档上具有唯一的变化，所述文档上形成的大多数图像呈现物理防反射， 复制特征满足预定义的标准，使得基于这些图像可以生成的大部分拷贝的所述特征不满足所述预定义标准;表征所述变体以形成形成的标记的唯一印记的步骤 ，对于每个所述文档和记录所述独特印记的步骤。 在实施例中，所述图像仅包括两种颜色。 在实施例中，在表征变化的步骤期间，利用频率分析。 在实施例中，在记忆步骤期间，印记存储在数据库中和/或文档中标记有表示单独贴在文档上的印记的标记。
