Abstract: The disclosure describes methods and apparatus of providing steganographic indicia or digital watermarking in image or video data. One implementation provides a method of embedding a digital watermark in image data captured by an imager, with watermark embedding occurring on-chip with the imager. Another implementation provides a method of managing images. Each of the images comprises plural-bit data steganographically embedded therein in the form of a digital watermark, with the plural-bit data corresponding to a geo-location. Yet another implementation provides a method of identifying locations on a map, with the map being for display via a computer display. Still another implementation provides a method of introducing a watermark message to a watermark embedder located on-chip with an image array. Other implementations and embodiments are provided as well.

Abstract translation: 本公开描述了在图像或视频数据中提供隐写标记或数字水印的方法和装置。 一种实施方案提供了一种将数字水印嵌入到由成像器捕获的图像数据中的方法，其中水印嵌入与成像器在芯片上发生。 另一个实现提供了一种管理图像的方法。 每个图像包括以数字水印的形式隐藏地嵌入其中的多位数据，其中多位数据对应于地理位置。 另一个实施方案提供了一种识别地图上的位置的方法，其中该地图用于经由计算机显示器进行显示。 另一个实施方式提供了一种将水印消息引入位于片上与图像阵列的水印嵌入器的方法。 还提供了其他实现和实施例。
