摘要： A computer-based method and a system for adding and printing variable security data. The system includes a memory, a processor, and a printer. The memory stores received print data. The processor modifies the print data for adding variable security print data and sends the modified print data for printing. The printer receives and prints the modified print data. The variable security data may vary between different printing operations. The processor captures a portion of the stored print data based on data-capturing criteria and modifies the stored print data based on the captured portion of the stored print data. The data-capturing criteria may be user-defined and may include leading tag data, trailing tag data, matching tag data, or combinations thereof for indicating a relative position of the captured data.

摘要： The present invention relates to an image forming device using a low visibility information embedding technique to manage a copy history of an original. The image forming device embeds history information with the use of small dots disappearing by copying, and coordinate information on a region embedded with the history information with the use of large dots not disappearing even by copying. Upon first copying, the image forming device newly creates both of the large dot coordinate information and the small dot history information, and embeds them. Upon second or later copying, the image forming device updates the history information having been read out of the original with that on the current copying, and embeds the updated history information in the history information region indicated by the coordinate information.

摘要： A method computes signal characteristics of a host signal in which a digital signal is encoded, and analyzes the characteristics to determine an extent to which the signal characteristics correspond to characteristics of the digital signal. The method adapts parameters of a predictive filter or prediction function applied to the host signal based on the extent to which the signal characteristics correspond to the characteristics of the digital signal. In one embodiment, different filters or filter parameters are selected to match different signal characteristics of the host signal with the characteristics of the digital signal. These predictive filtering techniques also enable optimized encoding of digital signals that adapt the encoding of digital signals to take advantage of predictive filtering in the decoding process.

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： Image, video, or audio data is encoded with both a frail and a robust watermark. The two watermarks respond differently to different forms of processing (e.g., copying the object may render the frail watermark unreadable), permitting an original object to be distinguished from a processed object. Appropriate action can then taken in response thereto.

摘要： A steganographic embedder embeds authentication data and value data into an object. This data is hidden yet machine readable from the object by, for example, scanning an image of the object and extracting a digital watermark from the object. A system for extracting this data includes an image capture device for capturing an image of the object and a steganographic decoder for extracting the steganographic data embedded in the image. The system uses the extracted data to authenticate the object and to associate an amount of value with the object. The value can be refreshed by using the steganographic data to reference a database where an updatable amount of value is stored.

摘要： The disclosure describes systems for creating and authenticating printed objects using authentication and copy detection watermarks. For example, one verification system includes a watermark decoder and a verification module. The watermark decoder detects a copy detection watermark in a printed object to determine whether the printed object has been reproduced. The verification module processes a message decoded from an authentication watermark on the printed object to authenticate the printed object or bearer of the printed object. The authentication and copy detection watermarks may be implemented as the same or different watermarks. For example, the copy detection watermark may be a fragile watermark that carries the message and that degrades in response to a reproduction operation, such as photocopying or scanning and then reprinting the object. Alternatively, the authentication and copy detection watermarks may be separate watermarks embedded in an image that is printed on the object. The authentication watermark, in some applications, includes an identifier that links the object to a database entry with related information about the object. This related information can be used to check the bearer of the object by comparing it with attributes of the bearer (such as a user ID or photo) or the validity of the object by comparing it with attributes that are visible or machine readable on the object.
摘要翻译：本公开描述了使用认证和复制检测水印来创建和认证打印对象的系统。例如，一个验证系统包括水印解码器和验证模块。水印解码器检测打印对象中的拷贝检测水印，以确定打印对象是否被再现。验证模块处理从打印对象上的认证水印解码的消息，以验证打印对象或打印对象的承载。认证和复制检测水印可以被实现为相同或不同的水印。例如，复制检测水印可以是携带消息的脆弱水印，并且响应于诸如复印或扫描的再现操作而降级，然后重新打印对象。或者，认证和复制检测水印可以是嵌入在打印在对象上的图像中的单独的水印。在一些应用中，认证水印包括将对象链接到具有关于对象的相关信息的数据库条目的标识符。该相关信息可以用于通过将对象与对象的属性（例如用户ID或照片）进行比较或对象的有效性与对象的可见或机器可读性的属性进行比较来检查对象的承载。
