摘要： A detachable keyboard for a telephone set is provided in the form of a keyboard card clipped to the headset, which is completely detached from the body when unclipped. Wireless communication between the handset body and keyboard is used when the card is unclipped, while contacts are activated in the clipped position so that the wireless handset then functions as in the case of a non detachable keyboard.

摘要： A visible seal or label containing a serial number is placed in plain view on the product packaging. The visible label contains the serial number as well as a first public key encrypted version of the serial number. A second or hidden label inside of the package has thereon a second a second encrypted version of the serial number made using a second public key. The hidden label may be secured inside of the package out of sight or may be placed on the back of the visible label and therefore viewable through a transparent case when opened or visible when peeled off. The private keys are known only to the manufacturer. Using a corresponding public key provided by the manufacturer, the consumer, law enforcement agent, or customs inspector can verify that the encrypted version matches the serial number. An advantage to this method is that only the manufacturer can produce matching pairs. Moreover, using a point of sale machine equipped with the public key the sales clerk can authenticate the product in front of the consumer at point of purchase. Additionally, in the case of a CD or other digital medium, the hidden label may comprise a digital watermark of the encrypted serial number such that a consumer, law enforcement agency, or customs inspector can readily detect a counterfeit product.
摘要翻译：包含序列号的可见密封或标签放在产品包装上的平面图中。可见标签包含序列号以及序列号的第一个公钥加密版本。包装内部的第二个或隐藏的标签上具有使用第二公钥制作的序列号的第二个第二加密版本。隐藏的标签可以固定在包装内部的视线之外，或者可以被放置在可见标签的背面上，并且因此当被剥离时打开或可见时通过透明外壳可以看到。私钥只有制造商才知道。使用制造商提供的相应公钥，消费者，执法人员或海关检查员可以验证加密版本是否符合序列号。该方法的优点在于只有制造商可以生成匹配对。此外，使用配有公钥的销售点销售员可以在购买点对消费者面前的产品进行认证。此外，在CD或其他数字媒体的情况下，隐藏的标签可以包括加密序列号的数字水印，使得消费者，执法机构或海关检查员可以容易地检测到假冒产品。

摘要： In order to verify the authenticity of manufactured goods, a smart tag is attached to the goods containing encrypted authentication information, such as a serial number, a description of the good's physical appearance or chemical decomposition, its color, or digital images of the good etc. The encryption procedure comprises public/private key encryption with zero-knowledge protocols. Zero knowledge protocols allow a smart tag to be authenticatable and yet be duplication resistant by allowing the verifying agent to convince him/herself that the smart tag is authentic without revealing its authentication information. The verification procedure can be done using a reader at a point of sale (POS) machine equipped with the appropriate public key and zero-knowledge protocols to decrypt the authentication information. A printed version of the serial number or other authentication information may be placed on the goods in human readable form to quickly verify the information electronically read from the smart tag. With the present invention, only the manufacturer can create such smart tags with the associated data thus making it virtually impossible to pass off a counterfeit good as authentic. In addition to authenticating counterfeit goods, the present invention can be used to detect authentic goods being sold in a parallel market.
摘要翻译：为了验证制成品的真实性，将智能标签附加到包含加密认证信息的商品，例如序列号，商品的物理外观或化学分解的描述，颜色或数字图像等。加密过程包括具有零知识协议的公钥/私钥加密。零知识协议允许智能标签是可认证的，并且通过允许验证代理说服他/她自己智能标签是真实的而不揭示其认证信息而被复制。验证过程可以使用配备有适当的公钥和零知识协议的销售点（POS）机器上的读取器来解密认证信息。序列号或其他认证信息的印刷版本可以以人类可读的形式放置在货物上，以快速验证从智能标签电子读取的信息。利用本发明，只有制造商可以使用相关联的数据来创建这样的智能标签，从而使得实际上不可能真实地将假冒商品传递出去。除了认证假货外，本发明还可用于检测在并行市场上销售的正品。

摘要： A method and apparatus for matching the print outputs of two printers having different characteristics. For the purpose of laser printing, or more generally for reproduction on any printing device with limited number of printing levels, a color or grayscale image has to be transformed into an array of printing decisions at each pixel of the output image. Sometimes this array is the only available representation of the original image. One may desire to print this array on a printer with different characteristics from the printer for which the array was originally prepared. The method and apparatus solve this problem by generating a printing decision matrix which takes into account the differences between the two printers.
摘要翻译：一种用于匹配具有不同特征的两台打印机的打印输出的方法和装置。为了激光打印的目的，或者更通常地，在具有有限数量的打印级别的任何打印设备上再现，颜色或灰度图像必须被变换成输出图像的每个像素处的打印决定的阵列。有时这个数组是原始图像的唯一可用表示。可能希望在具有与原始准备阵列的打印机不同的特征的打印机上打印该阵列。该方法和装置通过产生考虑到两个打印机之间的差异的打印决策矩阵来解决这个问题。

摘要： A printing method and apparatus takes into account the errors in the amount of black due to dot shape and size at the pixel where these errors occur, propagates corrections of these errors in order to preserve the logics of error diffusion, and permits a trade-off between completeness of the correction and computational time. The method and apparatus corrects for the actual shape of the printer dots in most error diffusion methods usable in digital halftoning.

摘要： Pages of books are copied without distortion due to curvature of the page near the book binding or the distortion in a copied page is corrected using the spacing of equidistant bars on tape strips applied to the top and bottom edges of a page before copying. The tape is preferably transparent and rather narrow and easily attached to a page to be copied. The first step in the distortion correction procedure is to locate the bars at the top and bottom of the page. The distortion of the spacing between the imaged bars is computed based on the known distance between the equidistant bars. The computed distortion of the spacing is then input to a distortion correction algorithm. The output of the distortion correction algorithm generates a corrected image. This image may also optionally delete the bars so that they are not printed in the copy. The corrected image is then copied.

摘要： A watermarking scheme is provided that allows the watermarked image to be authenticated by an authentication agent without revealing the human-readable content of the image. There is disclosed an approach that combines privacy control with watermarking and authentication mechanisms. The watermark can be made to be imperceptible to humans. Public key cryptography allows the authentication agent to authenticate without being able to watermark an image. Watermark information may also be encoded in a vector graphics image that includes at least one stroke defined by coordinate values of an ordered sequence of points. This may be obtained by providing watermark information as a bit sequence, identifying one or more redundant properties of the image, modifying the redundant properties based upon the bit sequence to generate a representation of the image and storing the representation of the image for subsequent use.
摘要翻译：提供了一种水印方案，其允许水印图像由认证代理认证，而不暴露图像的人可读内容。公开了一种将隐私控制与水印和认证机制相结合的方法。水印可以被人看不到。公共密钥加密允许认证代理进行身份验证，而无法对图像进行水印。水印信息也可以被编码在矢量图形图像中，该矢量图形图像包括由有序序列的坐标值定义的至少一个笔画。这可以通过提供水印信息作为比特序列，识别图像的一个或多个冗余属性，基于比特序列修改冗余属性来生成图像的表示并存储用于后续使用的图像的表示来获得。
