摘要： Provision is made in electronic document processing systems for printing unfiltered or filtered machine-readable digital representations of electronic documents, and human-readable renderings of them on the same record medium using the same printing process. The integration of machine-readable digital representations of electronic documents with the human-readable hardcopy renderings of them may be employed, for example, not only to enhance the precision with which the structure and content of such electronic documents can be recovered by scanning such hardcopies into electronic document processing systems, but also as a mechanism for enabling recipients of scanned-in versions of such documents to identify and process annotations that were added to the hardcopies after they were printed and/or for alerting the recipients of the scanned-in documents to alterations that may have been made to the original human-readable content of the hardcopy renderings.
In addition to storage of the electronic representation of the document, provision is made for encoding information about the electronic representation of the document itself, such as file name, creation and modification dates, access and security information, printing histories. Provision is also made for encoding information which is computed from the content of the document and other information, for purposes of authentication and verification of document integrity. Provision is also made for the encoding of information which relates to operations which are to be performed depending on handwritten marks made upon a hardcopy rendering of the document; for example, encoding instructions of what action is to be taken when a box on a document is checked. Provision is also made for encoding in the hardcopy another class of information: information about the rendering of the document specific to that hard copy, which can include a numbered copy of that print, the identification of the machine which performed that print, the reproduction characteristics of the printer, the screen frequency and rotation used by the printer in rendering halftones. Provision is also made for encoding information about the digital encoding mechanism itself, such as information given in standard-encoded headers about subsequently compressed or encrypted digital information.
摘要翻译：在电子文件处理系统中提供了用于打印电子文档的未过滤或过滤的机器可读数字表示，以及使用相同的打印过程将它们在相同记录介质上的人类可读渲染。可以采用将电子文件的机器可读数字表示与其可阅读的硬拷贝效果集成在一起，例如，不仅可以提高通过扫描这些硬拷贝可以恢复这种电子文档的结构和内容的精度而且还可以作为使得这些文件的扫描版本的接收者能够识别和处理在打印出来之后添加到硬拷贝中的注释和/或用于提醒被扫描文档的接收者的机制可能对硬拷贝效果图的原始人类可读内容进行的更改。除了存储文档的电子表示之外，还提供编码关于文档本身的电子表示的信息，例如文件名，创建和修改日期，访问和安全信息，打印历史。还针对从文档的内容和其他信息计算的编码信息，为了认证和验证文档完整性而进行编制。还规定了与根据在文件的硬拷贝呈现时制作的手写标记执行的操作相关的信息的编码; 例如，编码说明当检查文档上的框时要采取什么动作。另外还提供了硬拷贝中另一类信息的编码：关于该硬拷贝特有的文档的呈现的信息，其中可以包括该打印的编号副本，执行该打印的机器的标识，再现特性的打印机，打印机在渲染半色调时使用的屏幕频率和旋转。还提供了关于数字编码机制本身的信息的编码，例如关于随后的压缩或加密的数字信息的标准编码报头中给出的信息。

摘要： Original source verifying data defining a first source verifying image are stored in memory (62). The first source verifying image can be produced by a human making marks by hand in a field of a form, which can then be provided by a scanner (74) or a facsimile transmission (72) through image input circuitry (70). If a second source verifying image is received that is the same as the first source verifying image, an operation is performed that would not be performed if the images were not the same, such as an operation accessing a related item of data. For example, the first source verifying image can be received with a document image, and data defining the document image and the original source verifying data can be stored so that a source verifying image that is the same as the first source verifying image must be received before an operation can access the document data and provide it to image output circuitry for printing or facsimile transmission. As a result, the marked form is analogous to a key: Only someone who possesses the marked form or a high quality copy can obtain access to the document data. If the marked form is lost or destroyed, the document data cannot be accessed.
摘要翻译：定义第一源验证图像的原始源验证数据被存储在存储器（62）中。第一源验证图像可以由人类在形式的字段中通过手工制作标记产生，然后可以通过扫描仪（74）或传真传输（72）通过图像输入电路（70）来提供。如果接收到与第一源验证图像相同的第二源验证图像，则执行如果图像不相同则不会执行的操作，诸如访问相关数据项的操作。例如，可以用文档图像接收第一源验证图像，并且可以存储定义文档图像和原始源验证数据的数据，从而必须接收与第一源验证图像相同的源验证图像在操作之前可以访问文档数据并将其提供给图像输出电路用于打印或传真传输。因此，标记形式类似于一个关键字：只有拥有标记形式或高质量副本的人才能获得对文档数据的访问权限。如果标记的表格丢失或损坏，则无法访问文档数据。
