摘要： The present invention provides methods and apparatus for embedding an identifying pattern of visible speckles into the digitized image of each page of a document. A speckle is a cluster of black or white pixels. Speckles are printed as black speckles on the white paper, or conversely, as areas of missing black removed from the black text characters, called white speckles. The collective pattern of all embedded black and white speckles on a single document page is called a specklemark. A specklemark can survive contrast manipulations on photocopiers and binary rasterization done by fax scanning prior to data transmission. The random pattern of the black and white speckles visible in the digitized image of a document page can be detected automatically, and by systematically matching the detected pattern with those known to have been embedded into marked copies of a document page, a specific document copy can be identified. Methods for composing, embedding and detecting specklemarks are the subject of this patent.

摘要： The present invention provides methods and apparatus for imparting a multiplicity of watermarks onto a digitized image. The image includes a plurality of pixels, wherein each of the pixels includes brightness data that represents one brightness value if the image is monochrome, or a plurality of brightness data values if the image has multiple colors. In one aspect it provides for imparting more than one watermark into the digitized image comprising the steps of providing the digitized image, and multiplying the brightness data associated with at least one of the image pixels by a plurality of predetermined brightness multiplying value. Another aspect of the present invention is to provide a method for generating a composite watermark and imparting on a plurality of copies of a digitized image a different composite watermark into each copy. Also provided is a method for detecting one or more of the watermarks in the composite.

摘要： Digital data defining images are stored in a multiplane buffer. The buffer may store plural images by restricting data corresponding to an image or image portion to storage in less than half the bit planes of the buffer. An image is displayed by reading data from the buffer and selectively passing only a portion of the data read to a display. The data defining the images may be converted from facsimile (single bit per pixel) to gray scale format (multiple bits per pel) before being written to the buffer. The conversion relies on a table storing data definitive of the effect, on the image, of a facsimile transition (1/0 ot 0/1) as a function of the location of the transition. Conversion from facsimile to gray scale is effected by examining the facsimile data for data transmission and summing the effect of each of the transitions to convert a segment of facsimile data to gray scale data.A system is also disclosed for rapidly converting an image in run-end form to a reduced-resolution gray-tone image.
摘要翻译：定义图像的数字数据存储在多平面缓冲器中。缓冲器可以通过将对应于图像或图像部分的数据限制在不到缓冲器的一半比特平面中来存储多个图像。通过从缓冲器读取数据并且仅选择性地将读取的数据的一部分传送到显示器来显示图像。在写入缓冲器之前，定义图像的数据可以从传真（每像素单位）转换为灰度级格式（每像素多位）。该转换依赖于存储作为转换位置的函数的传真转换（1/0 ot 0/1）的图像效果的数据的表。通过检查用于数据传输的传真数据并将每个转换的效果相加并将一组传真数据转换为灰度数据来实现从传真到灰度级的转换。还公开了一种用于将跑步形式的图像快速转换为降低分辨率灰度色调图像的系统。

摘要： A digital watermarking method encodes different pairs of watermarks into each of a plurality of images offered for use by a vendor. The watermarks in each pair are derived from two separate collections of watermarks and sufficiently different so as to prevent false positives. Because each pair of watermarks is assigned to a different customer relative to a particular image, unauthorized use of a digital image sold to a customer may be determined by locating the associated pair of watermarks assigned to the customer in the image. Collusion detection is also realized by forming each pair of masks from sub-collections of masks which are detectable in an image formed by combining the same images sold to one or more customers.

摘要： A system and method for fourier transform coding of data on peak limited channels using a redundancy scheme. The system and method section the data to be transmitted into contiguous blocks having sequence lengths of 2N. Each block is coded in the frequency domain and its Inverse Discrete Fourier Transform (IDFT) for each coded block is computed. The IDFT blocks are then clipped at predetermined peak values .+-. P to thereby derive clipping error values. The magnitude of the clipping error values is then determined. The magnitude squared values of the clipping error is summed for each block. If the sum exceeds a threshold .phi. for a given block, then, the block is transmitted X number of times, where X is a fixed number, each time using less than the prescribed power for the transmission, otherwise, a continuous signal is transmitted whose sampled values at the Nyquist rate are the clipped values of the IDFT for that particular block.
