    Abstract: 本发明涉及一种文档的防拷贝方法,属于完全文档的保护技术领域。现有技术中,对于一些重要文档,特别是机密文档,由于资料完全保密,文件所有者常禁止拷贝该类文档,但是现有的技术还不能从根本上解决禁止拷贝的机密文档的非法拷贝问题。本发明所述的方法是在防拷贝文档中的原始图像下面嵌入防伪底纹,通过运行固化在拷贝设备中的应用程序检测防拷贝文档中隐藏的标记信息来判断是否可以合法拷贝该文档。采用本发明所述的方法,可以快速、准确地检测出防拷贝文档中的水印信息,从根本上切断了防拷贝文档被非法拷贝的途径,大大增强了防拷贝机密文档的安全系数,方法简单,不需要额外的硬件存储空间。

    Abstract: A latent image (16) is incorporated into an apparent solid-color background (28) for representing a desired solid-color background having a target color. An underlying solid-color background (20) is printed on a print medium (18) using a first color composition that differs from the target color. Line-screen patterns (24) embedding a latent image (16) in a visually- integrated setting (26) are printed over the solid-color background (20) using a second color composition that differs from both the first color composition and the target color. The visual characteristics of the line-screen patterns (24) forming the latent image (16) and the visually integrated setting (26) are matched for rendering the latent image (16) practically indistinguishable from the visually integrated setting (26) without a visual aid (30). The print densities of the line-screen patterns and the first and second color compositions are interrelated so that the line-screen patterns (24) in combination with the underlying solid-color background (20) produce the apparent solid-color background (28) in the target color.

    Abstract: This invention relates generally to document protection methods and product. More specifically, the present invention relates to a method for hiding information in a document by means of a latent image or message, which is practically invisible to the naked eye and may only be revealed through use of a matching viewing device. The present invention further relates to a method for creating original documents containing latent messages, which are revealed when the document is read by a viewing device. In one embodiment, print elements such as lines, dots, spots, swirls, or images are used to form covert information. The covert information print elements are disposed at an angle to print elements of a background, thus creating a covert document. In another embodiment, print elements of the covert information are used with a solid background.

    Abstract: A light source is configured to emit narrow peaks at discrete spectral bands, especially primary color wavelengths, added to simulate the effect of a broadband light source. A subject is provided with a pigment, examples being certain rare earth lanthanides, with a strong absorption peak at a corresponding narrow spectral band. The pigment has a nominal hue under true broadband light. When illuminated by the narrow band source, the absorption peak eliminates the contribution of one of the primary colors, producing a distinct shift in hue of the pigmented subject. The change in hue cannot be anticipated from the appearance of illuminated subjects that lack the pigment, which remain normal. The narrow absorption peak is not noticeable under unmatched light sources or true broadband light sources, e.g., sunlight. The hue shift effect is useful for security authentication, informational and decorative applications.
