    Abstract: This disclosure relates to advanced signal processing technology including signal encoding. One combination includes an apparatus comprising: memory for storing image data, the image data comprising a plurality of color separations or channels, in which the image data comprises at least a first type of machine-readable symbology comprising a 1D barcode represented therein and a second type of machine-readable symbology comprising a first signal represented therein, in which the second type of machine-readable symbology comprises a different type of machine-readable symbology relative to the first type of machine-readable symbology, the 1D barcode comprising a first plural-bit code and the first signal comprising a second plural-bit code; a barcode reader configured to analyze the image data to decode the 1D barcode to obtain the first plural-bit code; a signal decoder configured to analyze one or more color separations or channels of the plurality of color separations or channels to decode the first signal to obtain the second plural-bit code; one or more processors configured to determine whether the second plural-bit code and the first plural-bit code conflict; and to identify a conflict based on a conflict determination. Of course, other features and combinations are described as well.

    Abstract: Disclosed is a security controller for a content distribution system that generates and encodes point clouds with invisible, visually undetectable, and/or tamperproof watermarks. The controller selects a set of data points from the point cloud, and changes at least one specific bit of a set of bits that define a value for a particular non-positional element of the set of data points. The controller encodes point cloud with a first watermark that is unique to a requesting client based on the changing of the at least one specific bit. The controller distributes the file encoded with the first watermark to the requesting client and tracks the set of data points that were encoded with the first watermark in order to subsequently verify that the requesting client was the original recipient of the point cloud encoded with the first watermark.

    Abstract: A method for watermarking a three-dimensional object is disclosed. The three-dimensional object is represented by a mesh. A mesh comprises a plurality of vertices. The method further comprises computing an original thickness signature for said mesh from a plurality of thickness values, wherein a thickness value is computed for a vertex of the mesh; determining a target thickness signature, wherein the target thickness signature is a function of a watermark payload and of the original thickness signature; and modifying a position of at least one vertex of the mesh wherein a thickness signature computed for the modified mesh reaches the target thickness signature and wherein a distortion constraint between the mesh and the modified mesh is satisfied.A method for detecting a watermark in a three-dimensional object, a three-dimensional object carrying a watermark and, devices for implementing the methods are further disclosed.

    Abstract: In one aspect, assembly of multi-part food packaging is checked by reference to payloads of steganographically-encoded digital watermarks printed across plural components of the packaging. Marking all surfaces of the packaging components allows arbitrary orientation of feed stock in assembly equipment, and wide latitude in placement of inspection cameras along the packaging line. In another aspect, a scanner at a retail checkout station is alert to any gap detected in steganographic encoding on retail product packaging and, if found, alerts an operator to possible presence of an adhesive label with a misleading barcode. A great variety of others features and arrangements are also detailed.

    Abstract: Example methods disclosed herein include associating a first data pattern obtained from a first sequence of watermarks detected by a first media monitor at a first time with a first transmission of first media when the first sequence of watermarks include a first identifier associated with the first media. Disclosed example methods also include associating a second data pattern obtained from a second sequence of watermarks detected by the first media monitor at a second time with a second transmission of the first media when the second sequence of watermarks include the first identifier associated with the first media. Disclosed example methods further include comparing a third data pattern obtained from a third sequence of watermarks detected by a second media monitor with the first and second data patterns to determine whether the second media monitor monitored the first transmission or the second transmission of the first media.
