    • PROBLEM TO BE SOLVED: To provide a system for distributing, utilizing, and controlling digital works. SOLUTION: Rights of rendering in which watermark information for indicating information for corroborating a rendering result is clearly written are assigned to the digital work to be stored in a distribution repository. An encrypted version of the digital work is stored in a user repository from the distribution repository. When rendering of the digital work is requested, the user repository determines whether the digital work has appropriate rights of the rendering or not. When the digital work does, the user repository communicates with the rendering repository to establish a fiducial session, forwarding the digital work to the session. The rendering repository collects the watermark information written clearly in the rights of the rendering to encode data for a watermark and decodes the encryption of the digital work to embed the watermark information in the data encoded, thus transmitting the data embedded with the watermark information to a rendering device to perform the rendering.

    • 要解决的问题:提供分发,利用和控制数字作品的系统。 解决方案:明确写入用于指示用于确认呈现结果的信息的水印信息的渲染的权利被分配给要存储在分发存储库中的数字作品。 数字作品的加密版本从分发存储库存储在用户存储库中。 当请求呈现数字作品时,用户存储库确定数字作品是否具有适当的渲染权限。 当数字化工作完成时,用户存储库与渲染存储库通信以建立基准会话,将数字作业转发到会话。 渲染库收集在渲染的权利中清楚地写入的水印信息以对水印进行编码,并对数字作品的加密进行解码,以将水印信息嵌入到编码的数据中,从而将嵌入了水印信息的数据传送到 渲染设备执行渲染。 版权所有(C)2007,JPO&INPIT
