Problems solved by technology

Replicating the exact thickness and sequence of layers in a multilayer film substrate can be difficult for counterfeiters
Also, however, for determined counterfeiters, this may not be an insurmountable problem

Embodiment Construction

[0153] figure 1 Illustrated is an apparatus 100 for indicating whether an item 102, such as a security document, has one or more prescribed characteristics, according to one or more embodiments of the invention. If item 102 possesses these characteristics, it may be considered authentic. Otherwise, the item may be considered counterfeit or not authentic.

[0154] The device 100 comprises a processor 104 arranged to generate a signal indicative of detection of either a genuine or a counterfeit security document. This signal is communicated to an authenticity indicating unit 106 which, in response to receipt of the signal, is arranged to provide an indication of whether the security document is authentic or non-authentic.

[0155] In response to detection of a security document having a number of specified identifying characteristics, a positive signal (eg a signal indicating detection of an authentic security document) is generated. Designated identifying characteristics inc...

Abstract

The present invention provides apparatus for indicating if a security document comprises one or more specified characteristics, said apparatus comprising: an effect sensing device operative to sense at least one of: a stimulated effect arising due to: an interaction of a plurality of energy carrying particles and/or waves with a passive taggant material in said at least one reference layer; and an interaction of a plurality of energy carrying particles and/or waves with an interface between said at least one reference layer and at least one adjacent layer; and a spontaneous effect arising due to spontaneous emission of a plurality of energy carrying particles and/or waves from an active taggant material in said at least one reference layer; and output, to a processor of said apparatus, a sensed effect profile representative of said spontaneous and/or stimulated effect as sensed; wherein said processor is arranged to: derive a first data profile from said sensed effect profile; compare said first data profile with a second data profile representative of a specified effect profile; and produce an authentication signal representative of a match or otherwise between said first data profile and said second data profile. The invention also provides a method of indicating if a security document comprises one or more specified characteristics, and a banknote counting apparatus comprising the apparatus.

Description

technical field [0001] The present invention relates to an apparatus and method for indicating whether a security document includes one or more specified features, and in particular but not exclusively to a multilayer polymeric film substrate forming part of a security document indicating the presence or absence of those specified features Is real or counterfeit equipment and method. Background technique [0002] The use of polymer films as substrates is becoming more and more common in areas where security, authentication, identification and anti-counterfeiting are important. Polymer-based security documents in this field include eg banknotes, important documents (eg ID materials such as eg passports and title deeds, share certificates and education certificates), films for packaging high value goods for anti-counterfeiting purposes and security cards. [0003] Polymer-based safety materials offer advantages in terms of safety, functionality, durability, cost-effectiveness...
