Improved anti-counterfeiting techniques to confound modern scanners and photocopiers and safeguard medical prescriptions

有必要保护原始文件，以区别于伪造或欺诈性文件。 复制品例如，复印医生提供的处方并将其作为 原始文件给药剂师。目前有各种各样的技术被用来制作原始文件 未经修改不能复印或扫描的。Rx Security使用的空缩放仪仍然是一个 最有效的方法和最便宜的技术。复印和复印技术的最新发展 扫描技术已经使得空集电弓越来越不有效。这是因为成像系统 复印机的“低通滤波器”不再起作用了。因此，“无效”、“副本”或“无效” 不再出现在文件的影印或扫描版本中， 管理客户市场的防伪标准。RX安全公司已经接近大学 德蒙克顿提供了一个研究为基础的解决方案，日益复杂的复印机的问题， 扫描仪，因为它涉及到他们的产品线和防伪技术。 本课题的研究挑战如下：1）近年来，复印机和扫描仪的光学性能 变得几乎和眼睛系统的性能一样好，有时甚至更好。我们应该 研究一种挑战当今复印机和扫描仪高性能的解决方案， 核查应当是肉眼或常用技术（例如电话）可以进行的。2)的 解决方案应该是流畅的，无缝的实施，由公司使用它的当前生产 能力和设备。此外，转向新的和替代的反复制技术将 这意味着与成熟竞争对手进行更直接的竞争。3)因为复印机和扫描仪 变得光学性能高（过滤较少），解决方案可以集成高性能组件， 因此预计会增加费用。然而，解决方案不应该昂贵。4)的 必须遵守当前的生产标准（正面颜色、字体、图形内含物等）。

There is a need to protect original documents in order to distinguish them from forgeries or fraudulent duplications. For example, it is illegal to photocopy prescriptions provided by doctors and present them as original documents to pharmacists. A variety of techniques are currently employed to produce original papers that cannot be photocopied or scanned without alteration. Rx Security uses void pantographs which remain one of the most efficient methods and least expensive technologies. Recent developments in photocopying and scanning technologies have made void pantographs less and less effective. This is because the imaging system of the photocopier is not behaving as a "low-pass filter" anymore. Thus the word "void", "copy" or "invalid" does not appear anymore in the photocopy or scanned version of the document as required by the anti-counterfeiting standards which govern the clients' marketplace. RX Security has approached the Université de Moncton to provide a research based solution to the problem of increasingly sophisticated photocopiers and scanners as it relates to their product line and anti-forgery techniques. The research challenges are as follows: 1) Recently the optical performance of the photocopiers and scanners became almost as good as the performance of the system of the eye and sometimes even better. We should research a solution that challenge this high performance of today's photocopiers and scanners, however the verification should be doable by the eye or a commonly used technology (telephones for example). 2) The solution should be fluidly and seamlessly implementatble by the company using it's current production capacities and equipment. As well, departures into new and alternative anti-duplication technologies would imply more direct competition with well-established competitors. 3) Since the photocopiers and scanners became optically high performing (less filtering), the solution could integrate high performing components, and therefore it is expected to introduce more expenses. However, the solution should not be expensive. 4) The current production standards (color of the front side, font, graphical inclusions, etc) must be respected.
