Abstract: Methods and devices are provided to thwart analysis of a watermarking system by preventing analysis of watermarks in a host content. Upon receiving a content at a watermark embedding device, the content is analyzed to ascertain whether one or more test features are present in at least a first portion of the received content. When the analysis reveals that one or more test features are present, embedding of watermarks in at least the first portion of the received content is disabled. The test features of interest include a temporal, a spatial and/or a frequency characteristic such that, if a region of the content that includes test feature is embedded with a watermark, at least one characteristic of the embedded watermark is detectable upon analysis of that region. The test feature can, for example, approximate an impulse signal, a step function signal or a pure sinusoidal signal.

Abstract: Methods and devices are provided to embed imperceptible watermarks into a host content and to subsequently extract embedded watermarks in a manner so as to achieve desired levels of robustness, transparency and security. For a particular host content, a first number of embedding opportunities are used to insert watermarks, which is less than a number of all embedding opportunities within the host content. Watermarks are extracted from a first number of watermark extraction opportunities, which is less than a number of all watermark extraction opportunities associated with the host content. The relationship between the first number of embedding opportunities, the first number of watermark extraction opportunities and the number of all watermark extraction opportunities is such that a circumvention attempt that overwrites watermarks at all extraction opportunities degrades perceptual quality of the host content below a desired perceptual quality level.

Abstract: A watermark is embedded in a document having a plurality of pages. The pages of the document are analyzed to produce watermark information, which indicates whether the page is suitable for use with one or more of a plurality of watermarking schemes. The plurality of watermarking schemes may include page element shifting, flyspecking and text warping. An identifier (ID) is established, the ID associating the document with a user receiving the document. The ID is embedded in the pages of the document using the plurality of watermark schemes according to the watermark information. To recover an ID from a document, the pages of the document are analyzed to identify watermark information associated with the document. Embedded watermarks are recovered from the pages using the watermark information.

Abstract: At the time of marker attachment (at the time of encryption), for example, image conversion in which pixels to be overwritten by a marker are selected and pruned in a distributed manner and the pruning positions are moved to a marker attachment position is performed, and the marker is attached to the marker attachment position obtained as a result. At the time of marker elimination (at the time of decryption), for example, image reverse conversion in which each pixel of the marker is moved to the original position before the marker attachment is performed, each moved pixel of the marker is recovered, and the marker is eliminated.

Abstract: Methods and apparatus for enhancing the robustness of watermark extraction from digital host content are provided. Embedded watermarks may be extracted from received digital host content in accordance with a stego key. A first watermark is extracted and a number of errors in the first extracted watermark is assessed. If the number of errors is above a first pre-determined value, at least a second watermark is extracted from the host content. A number of errors in at least the second extracted watermark is assessed. If the number of errors in at least the second extracted watermark is above a second pre-determined value, the extraction results for the extracted watermarks are combined in order to cumulatively assess the validity of the first extracted watermark and at least the second extracted watermark.
