摘要： An example method is described in which a processor receives a first plurality of symbols selected from a first set of symbols, translates the first plurality of symbols into a second plurality of symbols selected from an M-ary cyclic symbol set, and writes the second plurality of symbols to a surface. An additional example method is described in which a processor captures an image of at least a portion of a surface, detects a first plurality of symbols from the image, where the first plurality of symbols comprises symbols selected from an M-ary cyclic symbol set, translates the first plurality of symbols into a second plurality of symbols selected from a second set of symbols, and performs at least one task responsive to the second plurality of symbols.

摘要： First and second patterns are formed on a substrate. A spatial offset between the patterns is determined, and stored for later use in authenticating the substrate. (One or both of the patterns may convey steganographic information. One pattern may be printed, while the other may be embossed.) A smartphone can sense these patterns, determine the spatial offset, and check whether the determined offset matches the earlier- stored offset, to judge whether the substrate is authentic. Another arrangement effects serialization of product packaging by use of paired patterns (at least one of which is typically a steganographic watermark pattern) applied in a manner causing a spatial offset between the patterns to progressively vary along a length of a printed web. Still other arrangements involve substrates conveying patterns that degrade over time, e.g., indicating freshness or pressurization condition. A great variety of other features and arrangements are also detailed.
摘要翻译：在基板上形成第一和第二图案。确定图案之间的空间偏移，并存储以供以后用于鉴定基板。（一个或两个图案可以传达隐写信息，一个图案可以被打印，而另一个图案可以被压印。）智能手机可以感测这些图案，确定空间偏移，并检查所确定的偏移是否与早先存储的偏移匹配，以判断底物是否可靠。另一种布置通过使用以导致图案之间的空间偏移的方式沿着打印幅材的长度逐渐变化的配对图案（其中至少一个通常为隐写水印图案）来实现产品包装的串行化。另外的其它布置包括传送随时间降解的图案的基底，例如指示新鲜度或加压条件。还详细介绍了各种各样的其他功能和安排。

摘要： A method of watermarking an image (l o ). A visible watermark (T) is inserted (23) in the image (I0) to obtain a visibly watermarked image (l v ). Information (22) allowing removal of the visible watermark (T) is protected (24) to obtain protected information (26) that is inserted (27) as an invisible watermark in the visibly watermarked image (l v ) to obtain a visibly and invisibly watermarked image (l Vι ).

The visible watermark may be opaque. Also provided are an apparatus for inserting the watermarks, a method for removing the visible watermark, essentially by performing the method "in a mirror", and an apparatus for removing the visible watermark.

摘要： Methods, apparatus, and systems for signal continuity assessment using embedded watermarks are provided. The embedded watermarks are recovered from the content and one or more attributes associated with the recovered watermarks are identified. A continuity of th content can then be assessed in accordance with the one or more attributes. The continuity assessment may be based on a variety of factors, including but not limited to a determined heartbeat of the recovered watermarks, a density, separation, location, or extent, of the recovered watermarks, as well as information associated with the watermarks, such as a stego key, channel bits, packet numbers, a fingerprint, or the like.

摘要： A hybrid watermark insertion method includes the steps of dividing the digital image into a low frequency region and a high frequency region using an edge map of the digital image; inserting a watermark into the low frequency region of the image by employing a watermarking method using a human visual system (HVS); and inserting the watermark into the high frequency region of the image by employing a quantization index modulation (QIM) method. A hybrid watermark extraction method includes the steps of estimating a reference value used when inserting a watermark, and searching a maximum value of correlation coefficients in an image of the watermark image while changing the estimated reference value within a designated range, to thereby find out the watermark insertion method. Accordingly, the watermark insertion method can be easily identified, thereby enabling the watermark extraction in a more readily manner.

摘要： The invention relates to embedding in, as well as to extracting a payload from a motion image signal. Furthermore, the invention relates to a motion image signal. A payload is embedded in the motion image signal by the following steps. A first and an at least second watermark are represented by at least a first sequence of watermark samples, and a first and at least a second global property of an image of the signal are determined. Subsequently, the first and the at least second watermark are embedded in the signal, so that a shift of the at least second watermark with respect to the first watermark represents the payload. The first and the at least second watermarks are embedded by modifying the first and the at least second global property in the image in accordance with the corresponding watermark samples. The first and second global properties may be the mean luminance and the mean color saturation of the pixels constituting the image.

摘要： Methods are provided for embedding auxiliary information in a host content signal which reduce the memory, bandwidth and computational complexity of the embedding and transmission systems. In one embodiment, a first reduced-scale signal is produced which corresponds to the host content embedded with a first logical value and producing a second reduced-scale signal corresponding to the host content embedded with a second logical value. A first set of segments from the first reduced-scale signal may be combined with a second set of segments from the second reduced-scale signal in a pre-defined manner to produce a composite embedded host content. Thus the storage and transmission requirements of the watermarking system are reduced to having to deal with only the original content plus two reduced-scale signals.
