  • Publication number: 20090243279
    Abstract: The invention relates to a security device for security substrates, such as paper, used for making security documents, such as bank notes, having anti-counterfeitable features. The security device comprising a carrier (11) of an at least partially light transmitting polymeric material, said carrier bearing a plurality of fine opaque lines (13) separated by gaps (14). The appearance of the lines is varied at regions, said regions in neighbouring lines combining to provide identifying indicia which are visible to the human eye.

  • Patent number: 6155605
    Abstract: A document of value such as a banknote comprises a substrate having a security feature in or on one region of the substrate. The security feature has at least one machine authenticatable high security entity (HSE) and at least one further machine authenticatable entity comprising a low security entity (LSE) or a high security entity, the at least two entites providing different detectable characteristics. The or each HSE is an homogeneous mixture of at least two components exhibiting different detectable characteristics, and the LSE is a single component exhibiting a detectable characteristic different from those exhibited by the HSE.

  • Patent number: 5678863
    Abstract: A means of identification or document of value which includes a paper or polymer region, in particular, bank notes, passports, identification cards or any other document of sufficient value to make it liable to be copied or counterfeited, includes a watermark in the region and a liquid crystal material applied to the region and to at least a part of the watermark to produce optical effects which differ when viewed in transmitted and reflected light.
