    • A method and system for authenticating an item by using a security marking. The security marking is provided on the item with an OVD ink capable of absorbing light in a visible wavelength range to appear visibly black and producing a red fluorescent emission under ultraviolet excitation. Under visible light illumination and ultraviolet excitation, a visible image and a fluorescent image are obtained from the security marking using image scanners. The images are compared to find a substantial match with each other. The security marking can be a postage indicium, a barcode, a symbol, a message or an image. The item to be authenticated can be a mailpiece, a banknote, a tag, a ticket, a document, an identification card, or the like.

    • Improvements are provided in processing of documents to increase their security and/or decrease the complexity of testing for authenticity. Methods for printing documents with security markings and methods and apparatus for authenticating documents are described. In one aspect a document is printed with a security marking comprised of an image printed in at least two image segments. The image can be printed with an ink capable of forming images which are visible both to viewing under white light and as fluorescent images when irradiated with ultraviolet light, the segments having features of different sizes. The relative sizes of the two image segments will provide a detectable difference in fluorescent image sharpness. The apparatus provides means, all of which are simple and easily available for carrying out the methods.

    • Disclosed are optical codes, e.g., DataMatrix bar codes, of enhanced security and readability and a process for printing one. These codes are comprised of a perimeter finder pattern providing a target area and a pattern of symbology defining a data field in fixed position relative to the target area. Preferably, at least a portion of the optical code so defined is printed in a black fluorescent ink in order to enhance the signal to noise ratio in the environment of other visible, monochrome printing. The invention simplifies the detection of the machine-readable symbology for reading by optical code reader and provides enhanced security features. The image is a covert composite of a visible light readable and a fluorescent image. If fluorescent image is not detected or does not match a reference image, then it can be rejected as an unauthentic, e.g., simple copy image.
    • 公开了具有增强的安全性和可读性的光学代码,例如DataMatrix条形码以及用于打印它们的过程。 这些代码包括提供目标区域的周界寻找器图案和定义相对于目标区域处于固定位置的数据字段的符号体系图案。 优选地,如此定义的光学代码的至少一部分被印刷在黑色荧光墨水中,以便在其它可见的单色打印的环境中增强信噪比。 本发明简化了用于由光学代码读取器读取的机器可读符号系统的检测,并提供增强的安全特征。 图像是可见光可读和荧光图像的隐蔽复合物。 如果未检测到荧光图像或与参考图像不匹配,则可以将其拒绝为不真实的,例如简单的复印图像。
