    • Various embodiments include an apparatus and a method to secure protected digital document content from tampering by their user, such as unauthenticated use or use violating a policy of the digital document. The digital document file can be transferred from a network node such as a web site server to a digital appliance, such as a computer, in encrypted form. The digital document file can be resident already on a device, and/or be transferred into a device that is connected to the digital appliance. The device (hereafter a DRM device) can internally store the digital document or part of the document. The DRM device may decrypt the digital document when requested to do so. The device may further format the content for usage, for example, convert text into its graphic bitmap representation. Device formatting can include sending plain text data to the digital appliance. The device may further process degradation to the resulted file, for example, reduce the resolution of the graphic representation. The digital appliance uploads the result of the processing or sections of the result of the processing for user access via the digital appliance.
    • 各种实施例包括一种用于保护受保护的数字文档内容免受其用户篡改的装置和方法,例如违反数字文档的策略的未认证的使用或使用。 数字文档文件可以从诸如网站服务器的网络节点传送到加密形式的诸如计算机的数字设备。 数字文档文件可以驻留在设备上,和/或被转移到连接到数字设备的设备中。 该设备(以下称为DRM设备)可以在内部存储数字文档或文档的一部分。 当请求时,DRM设备可以解密数字文档。 该装置可以进一步格式化用于使用的内容,例如将文本转换成其图形位图表示。 设备格式化可以包括将纯文本数据发送到数字设备。 该设备可以进一步处理所得文件的劣化,例如降低图形表示的分辨率。 数字设备通过数字设备上传处理结果或用于用户访问的处理结果的部分。
