摘要： An image watermarking method includes a color transform on RGB image data to derive CMYK image data that define a constant K image. Variable infrared (IR) mark data defining an IR mark are received and a sparse two-dimensional pattern of black pixels is defined that corresponds to the variable IR data, e.g., using Gold codes or pseudorandom binary sequences. A watermarked black separation K″ is defined by embedding the sparse two-dimensional pattern into the constant K black separation K′ while maintaining local average levels. A watermarked image includes the watermarked black separation K″ in combination with the CMY separations of the constant K image. A decoding process includes using an IR microscope fitted with IR LEDs and an IR pass filter to capture an IR image, which is subjected to exposure correction, thresholding, and dilation operations to extract the two-dimensional pattern for subsequent correlation processing.

摘要： Methods for adapting the operation of a system in response to the detection of embedded watermarks from a digital host content are provided. A digital host content is received and examined for the presence of watermarks. In response to the detection of embedded watermarks and in accordance with the value, type, density or spacing of the detected watermarks, one or more system reactions may take place. These reactions include conditionally allowing the system to resume its normal operation, prohibiting the system from resuming its normal operation, degrading the quality of the digital host content or changing the security status of the digital host content. In response to the extraction of weak watermarks that do not meet the desired system requirements, the extraction operation may be modified or extended to enable the detection of strong watermarks.

摘要： The ability to remove a watermark from encoded content (e.g., an image) opens the possibility of various novel applications. Several such applications are detailed. One employs a reversible watermark in conjunction with a second (robust) watermark. In this arrangement, the payload of the reversible watermark conveys information about the robust watermark (e.g., encoding parameters, or an error signal), permitting removal of the robust watermark from an uncorrupted encoded image. By such arrangements, the encoded image can be fully restored to its pristine, unencoded state even if several different watermarks have been applied.

摘要： Systems and methods for detecting copies of documents are described. In one example, a system and method for detecting copies of documents utilizes multiple authentication tests performed using original and scanned copy detection patterns. The system captures a CDP that may be skewed or improperly sized. The system also retrieves or reconstitutes the expected CDP. Then the system performs a first correlation to determine if the captured CDP indicates the correct document identification and then if necessary, one or more authentication tests are applied wherein the authentication test may be grouped into distinct orthogonal test groups. The authentication tests applied may be selected according to usefulness, system throughput or target document valuation parameters.

摘要： The disclosure describes methods for adaptive prediction filtering for digital watermarking applications. The predictive filter is designed to predict the digital watermark signal. In one implementation, there are two stages of prediction filtering. A first stage operates on a suspect signal before detecting any watermark in that signal. This stage adapts the predictive filter to local signal characteristics. A second stage uses known watermark signal elements to adapt a non-linear filter used in extracting message symbols from the suspect signal. This stage produces detection statistics based on a comparison of expected and measured message symbol values, and uses these statistics to adapt the parameters of a predictive filter. This adapted prediction filter is then applied to extract message symbol estimates.

摘要： A system for determining the amount of processing that has been applied to watermarked signal. A steganographic signal is provided that includes an original signal and an embedded fragile watermark. The fragile watermark is characterized by a low energy and a high redundancy in comparison to a robust watermark. The steganographic signal is communicated over a distribution channel to a decoder. At the decoder, a measure of a presence of the fragile watermark in the acquired steganographic signal is provided, along with an estimate of the fragility profile of the fragile watermark for this particular original signal. Based on these factors, a estimate is made of the amount of processing that the steganographic signal has undergone. This processing can include, for example, A/D and D/A conversions, resampling, band-limiting, perceptual compression/decompression, etc. Optionally, the fragility profile is derived prior to the distribution of the content and communicated by the steganographic signal for recovery by the decoder. Furthermore, a robust watermark may be provided in the steganographic signal that, e.g., designates the presence of the fragile watermark to a decoder.

摘要： A watermark embedder transforms a media signal from its perceptual domain to frequency domain regions and embeds a hash of data from one frequency domain region into a watermark in another frequency domain region. Alternatively, it encodes instances of the same message into the frequency domain regions. To detect alteration of the media signal, a watermark decoder transforms a suspect signal into the frequency domain regions, extracts the watermark message from a first frequency domain region and compares it with a reference derived from another frequency domain region. The reference signal is either a hash computed from the other frequency domain region of the watermarked signal, or another instance of the same message embedded into the other frequency domain region. The decoder can be used to detect alteration of the signal, such as alteration that occurs with reproduction (printing, scanning, copying, D/A-A/D conversion, etc.), compression, cropping or swapping of media signal content, etc.
