Abstract

The use of one or more optical fibres in or on an article enables identification or verification thereof. Thus, a method for the identification or verification of an article may be effected by detecting the presence or absence of one or more optical fibres in or on it, or the arrangement of the fibre(s), wherein light is shone on a first area of the article and the emission of light from a second area of the article is detected for, to determine the presence or absence of an optical fibre running between the two areas of the article. <IMAGE>

Description

SPECIFICATION Identification of articles The present invention relates to the secure identification or verification of articles.
There is an increasing demand for a means to verify or identify articles which is secure from unauthorised tampering. For instance, it is common to magnetically encode plastics cards for a variety of purposes, for instance for cash dispenser machines or automatic security gates, such as for car parks. The use of bar codes is now common, as in point-of-sale terminals in supermarkets.
It has also been known for many years to incorporate metal strips in bank notes and various proposals have been made for incorporating security devices in passports.
The present invention provides the use of one or more optical fibres in an article for the indentification of verification thereof.
Also provided is a method for the identification or verification of an article by detecting the presence of absence of one or more optical fibres in or on it, or the arrangement of the fibre(s), wherein light is shone on a first area of the article and the emission of light from a second area of rhe article is detected for, to determine the presence or absence of an optical fibre running between the two areas of the article.
The invention further includes and article having arranged therein or thereon one or more optical fibres extending from one area of the surface thereof to a second area for the verication or identification of the article.
It is envisaged that a particularly desirable application of optical fibres in this way is in connection with security documents. We use the term "security document" in its broadest term to cover not only items such as cheques, banknotes and passports but also credit and cheque cards, for example.
At its simplest the invention involves the use of a single optical fibre to verify that an item, such as a banknote, is genuine. The banknote would, for example, incorporate an optical fibre lying across it, each end of the fobre being exposed at the edge of the note.
To verify the authenticity of a note, a light is shone at one edge of the note and the other edge is observed for the presence of a fibre in the correct position. The note could be verified manually or using a machine incorporating a light detector. A plurality of fibres could, of course, be used. The accompanying Figure shows a banknote 1 having fibres 2 extending thereacross.
In a more sophisticated embodiment of the invention a plurality of optical fibres are incorporated in an article to provide an identifiable code, for instance by identifying the pattern in which the fibres are arranged.
Thus, a card for a cash dispenser or pointof-sale automatic debitting machine could have a plurality of optical fibres running across it. Upon insertion into a card reader, light is shone at one edge of the card and the arrangement of the optical fibres is determined using photosensitive devices facing the opposite edge of the card which detect light transmitted by the optical fibres.
It is convenient to detect the optical fibres with the fibres bent so that the fibre ends distal to the light source are out of the path of the light shone from the source. This is one way of preventing light shining directly from the source impinging upon the light detectors.
If the fibres are in or on a flexible article, e.g. a paper document, they can be arranged in a straight line in or on the article which is then bent in the detection apparatus. Alternatively, whether the article is flexible or rigid, the fibres may be arranged angularly so that the article does not need to be bent in the detection apparatus.
The pattern in which a plurality of fibres are arranged may be ascertained either by having the article stationary in the detection apparatus and detecting which of a plurality of photosensitive units are activated, or by moving the article past a single sensor and determining the interval between successive activations of the sensor.
The optical fibres are incorporated in the article in any convenient way. For instance, in the manufacture of banknotes or other paper documents, e.g. cheques or passports, one or more reels of optical fibre are placed above the paper making machine. Pulp stock on a wire is passed beneath the reel or reels and the fibre(s) are fed onto the pulp stock. A twin-wire machine may be used in which case the optical fibre(s) could be sandwiched between the two webs formed by each wire.
The finished paper is then cut into the desired size, having the optical fibres arranged in a selected pattern, if it is wished.
We have found it easier to space the fibres apart when making paper documents in this way, when more than one fibre is used, rather than to cluster them together.
CLAIMS:
1. The use of one of more optical fibres in or on an article for the identification or verification thereof.
2. A method for the identification or verification of an article by detecting the presence of absence of one or more optical fibres in or on it, or the arrangement of the fibre(s), wherein light is shone on a first area of the article and the emission of light from a second area of the article is detected for, to determine the presence or absence of an optical fibre running between the two areas of the article.
3. A method as claimed in claim 2 wherein the second area is positioned out of the line of travel of the light shone onto the
