Patent number: 6839524Abstract: An image forming apparatus can form an image of a high-precision security information for anti-reproduction. A photosensitive material-coated area in a recording paper is exposed with an exposure unit to form an image of a high-precision security information. Since the image of the security information is thus formed by exposing the photosensitive material, it can be formed as an image incapable of reproduction.Type: GrantFiled: September 17, 2002Date of Patent: January 4, 2005Assignee: Fuji Xerox Co., Ltd.Inventors: Shoji Yamaguchi, Mario Fuse, Hideki Fukunaga, Tetsuya Kimura

Publication number: 20040114190Abstract: A form of stochastic random distribution is used to print an invisible watermark using a typical, e.g. 600 dpi, printer. The watermark contains such information as “Do Not Copy,” or other such information. While the watermark is not visible on a first generation version of a document that is printed, various techniques are used to print the watermark in such a way that it becomes readily apparent when the first generation document is photocopied. The preferred embodiment of the invention is concerned with a technique for improving such techniques, for example so that gray levels are improved to address variations from printer to printer. Another preferred embodiment of the invention is also concerned with a technique for performing error diffusion watermarking without the need for performing a calibration step.Type: ApplicationFiled: December 12, 2002Publication date: June 17, 2004Inventor: Lai Chee Man

Publication number: 20040114160Abstract: The present invention relates to the manipulation of differential gloss as may be inherent in halftoned images by utilization of tags. By selectively applying halftones with anisotropic structure characteristics, which are significantly different in orientation while remaining identical in density, as directed by tag settings, a gloss image may be superimposed within an image without the need for special toners or paper. Conventional copier systems will not typically be able to copy such a superimposed gloss image.Type: ApplicationFiled: December 12, 2002Publication date: June 17, 2004Applicant: Xerox CorporationInventors: Shen-Ge Wang, Beilei Xu, Chu-Heng Liu

Patent number: 6738491Abstract: Additional data useful for the management of copies of a document for an image forming apparatus is embedded in a hard copy of the document. The additional data is embedded in an image of a document as discrete dots arranged in a prescribed format. Preferably, the size of each of said discrete dots is such as not to be recognized easily with the naked eye. The image data for embedding the additional data can be obtained by reading a document, or by receiving data sent from a computer. Additional data embedded in a hard copy can be extracted from the image data on the hard copy. Further, the production of a copy according to the image data, can be controlled according to the extracted additional data. Additional data is generated for each copy according to the extracted additional data for embedding it in a hard copy to identify each copy.Type: GrantFiled: August 14, 1997Date of Patent: May 18, 2004Assignee: Minolta Co., Ltd.Inventors: Yoshikazu Ikenoue, Hideo Kumashiro, Munehiro Nakatani
