    • PROBLEM TO BE SOLVED: To facilitate scale and rotation calibrations for steganographic decoding, improve techniques for decoding without access to unencoded originals, and also improve robustness of steganographic coding in motion pictures. SOLUTION: A system includes: a step of creating a set of standards by which URL addresses are steganographically embedded within images, video, audio, and other forms of data objects; and a step of designing web site development tools 1008 and web software such that they recognize the new type of data objects 1006 (the hot object). The tools are designed such that when the objects 1006 are presented to a user and that user points and clicks on the object 1006, a user's software 1010 reads or decodes the steganographic information and notifies the user to the decoded URL address.

    • 要解决的问题:为了便于隐写解码的缩放和旋转校准,改进解码技术,而无需访问未编码的原稿,并且还提高运动图像中隐写编码的鲁棒性。 解决方案:系统包括:创建一组标准的步骤,通过该标准将URL地址隐藏地嵌入在图像,视频,音频和其他形式的数据对象中; 以及设计网站开发工具1008和网络软件的步骤,使得他们识别新类型的数据对象1006(热对象)。 这些工具被设计成使得当对象1006被呈现给用户并且用户指向并点击对象1006时,用户的软件1010读取或解码隐写信息,并将用户通知解码的URL地址。 版权所有(C)2008,JPO&INPIT
