Abstract
An article (12), especially when in sheet form such as a document and which carries insignia like letters and numerals on a first side, is rendered tamperproof by adhering a transmissive (16), e.g. transparent layer to the first side of the article over the insignia (14), and severing the article from a second side opposed to the first side, e.g. by means of cuts, which do not penetrate through the transmissive layer (16). A second layer (18) can be adhered to the second side and the layered article can be severed also from the first side, e.g. by means of cuts which do not coincide with the cuts from the second side and which do not penetrate through the transmissive layer (16). The portions of the article carrying the insignia (14) are held in their original orientations and positions by the intact portions of respectively the transmissive layer (16) and the second layer (18). If the insignia are accessed, e.g. to alter the insignia, the portions carrying the insignia (14) are no longer held in place, which is readily detectable.
Description
CA 0223206~ 1998-03-13 W O 97/10107 PCT~US96/14700 PROTECTING AN ARTIC~E
THIS INVENTIGN relates to protecting an article.
It relates more speci~ically to a method o~ rendering a predetermined sur~ace portion of the article tamperproo~.
It relates also to a composite, layered article including an article which is tamperproo~.
The Applicant believes that this invention can aavantageously be applied to articles in layer or sheet ~orm, most advantageously to such articles carr~ing insignia ~e.g. in the ~orm of letters ~orming words, figures or numbers, diagrams, znd the like) in visible ~o~.
(e.g. in written, typewritten, printed or like ~orm), such as cheques, bonds, share certi~icates, other negotiable documents, non-negotiable documents or cards such as identity cards, drivers licences, passports, and the like.
In accor~ce with a ~irst aspect o~ this invention, there i5 provided a method o~ rendering a CA 0223206~ 1998-03-13 W O 97/10107 PCTnUS96/14700 predetermined sur~ace portion o~ an article tamperproo~, including adhering a transmissive layer over said predetermined sur~ace portion;
severing said sur~ace portion into ~ragments; and retaining said ~ragments in their original positions and orientations by means o~ said transmissive layer.
By "transmissive layer~ is meant a layer having properties appropriate to allow access to the sur~ace portion to allow the sur~ace portion to be used ~or its intended purpose. For example, i the sur~ace portion carries insignia intended to be observed by the eye, the transmissive layer will be transparent, e.g. in the ~orm o~
a transp~rent ~ilm.
Adhering the transmissive layer over said predetermined surface portion may be ~rom a ~irst side corresponding with said predetermined sur~ace portion, the method including adhering a second layer over said article ~rom a second side opposite to said ~irst side. Severing said sur~ace portion into ~ragments may then be e~ected ~rom said second side, severing being in respect o~ the second layer and the article in unison.
The method may include also severing the transmissive layer and said predetermined sur~ace portion into ~ragments, and retaining said ~ragments in their W O 97/10107 PCTrUS96/14700 original positions and oriencations by means of said second layer. Said severing, or said severing ~rom the second side, may be e~ected by cutting into and through the predetermined sur~ace portion, said cutting not penetrating through the transmissive l~yer.
However, severing the transmissive layer and said predetermined surlace portion may be e~~ected Irom the ~irst side by cutting into and through the transmissive layer and the predetermined sur~ace portion, said cutting not penetrating through the second layer.
Cutting ~rom the second side may be by ~orming cuts in parallel. Similarly, cutting ~om the ~irst side may be by ~orming cuts in parallel. Pre~erably, cutting ~rom the ~lrst side may be transverse to cutting ~rom the second side, such that cuts, even though thev may intersect, will not coincide ~or any appreciable distance.
By way o~ development, cutting ~rom the second side may be by ~orming cuts in criss-cross or chequered ~ashion, e.g. by means o~ two sets o, parallel lines which ~0 are mutually transverse, conveniently about perpendicular.
Similarly, cutting ~rom the ~irst side may be by ~orming cuts in criss-cross or chequered ~ashion such that cu~s ~rom the ~irst side do not coincide ~or any CA 0223206~ 1998-03-13 WO 97/10107 PCT~US96/14700 appreclable distance with cuts ~rom the second side. Thus, advantageously, respective cuts ~rom the ~irst side may be generally parallel to and o~set ~rom respective cuts ~rom the second side.
5It is important to appreciate that the cuts need not be straight; they may, ~or example, be wavy.
In accordance with a second aspect o~ this invention, there is provided a composite layered article including 10an article having a pr_determined sur~ace portion which is to be rendered tamperproo~;
a transmissive layer adhering to a ~irst side o~ the article over said predetermined sur~ace portion, the Fredetermined sur~ace portion being severed into ~ragments, lSthe ~ragments being retained in their original positions and orientations by means o~ the transmissive layer.
In a pre~erred embodiment, the article may be in the ~orm o~ a sheet carrying insignia on the sur~ace portion. The insignia may be intended to be observed by 20the eye, the transmissive layer then being in the ~orm o~
a transparent ~ilm.
The composite layered article may include also a second layer adhering to a second side o~ the article opposite to said ~irst side, said second layer and the CA 0223206~ l998-03-l3 article in the regicn o~ the predetermined surrace portion ~ heing severed in unison by means o~ cuts penetrating the composite article ~rom the second side and extending through the article, but not penetrating through the transmissive layer.
Similarly, the composite layered article may be severed also by means o~ cuts ~rom the ~irst side penetrating the transmissive layer and the predetermined sur~ace portion and nct penetrating thrcugh the second layer, to ~orm ~ragments which are retained in their original positions and orientations by means o~ the second layer.
Said cut~ ~rom the second side may be parallel.
Said cuts From the ~irst side may be parallel.
Advantageously, said cuts ~rom the second side and said cuts ~rom the ~irst side may be mutually transverse, such that the respective cuts, even though they may intersect, will not coincide for any appreciable distance.
By way o~ development, said cuts ~rom the second side may be in criss-cross or chequered ~ashion, e.g. in the ~orm o~ two sets o~ parallel llnes which are mutually transverse, conveniently about perpendicular.
Similarl~r, said cuts from the ~irst side may be in criss-cross or chequered ~ashion and such that they do CA 0223206~ 1998-03-13 W O 97/10107 PCT~US96/14700 not coincide ~or any appreciable distance with cuts ~rom the second side. Thus, advantageously, respective cuts ~rom the ~irst side may be parallel to and o~se~ ~rom respective cuts rrom the second side.
5Advantageously, said article may be in the ~orm o~ a document carrying insignia in the ~orm o~ at least one o~ letters ~orming words, ~igures and diagrams.
Said document may be in the form o~ a negctiable document. Instead, it may be in the ~orm o~ another kind 10o~ document o~ which the integrity is important, such as an identity card, a driver's licence, a passport, or the like.
The invention is now described by wav o~ example with re~erence to the accompanying diagrammatic drawings.
In the drawings 15Figure 1 shows, in ~rontal view, a partially cut-away view o~ a composite layered article in accordance with the invention in the ~orm o~ a negotiable document;
Figure 2 corresponds to Figure 1 but shows the negotiable document in side view;
20Figure 3 shows, to a much enlarged scale, ~ragmentarily, an edge view o~ the negotiable document o~
Figure 1; and Figure 4 corresponds to Figure 1, but shows a developed and more elaborate cutting pattern applied to the 25composite layered article.
CA 0223206~ 1998-03-13 With rererence to Figures l to 3 o~ the drawings, a composite layered article in accordance with the invention, and more speci~ically including an article 12 in the ~orm o~ a negotiable document, is generally indicated by re~erence numeral lO. The negotiable document 12 is in the ~orm o~ a sheet 12 carrying insignia in the ~orm o~ =
letters ~orming words, ~igures or the like and can be in written, type-written, printed, or like ~orm. The negotiable document in the ~orm o~ the sheet 12 is rendered tamperproof in accordance with this invention.
A covering layer o~ a transmissive material 16 adheres to an upperside or ~irst side o the sheet 12, directly over the insignia 14.
A second layer 18 covers the rea~ or the reverse side o~ the sheet 12.
Thus, the sheet 12, sandwiched between, and together with, the ~irst or transmissive layer 16 and the second or rear layer 18, ~orm a composite article in accordance with the invention, and more speci~ically such that the insignia 14 on the sheet 12 are rendered ~ tamperproo~ in accordance with the invention. For clarity o~ drawing, the transmissive layer 16 is shown as i~ torn o~ at 16.1 to show the sheet 12 underneath. Similarly, the sheet 12 is shown as i~ torn o~ as indicated by CA 0223206~ 1998-03-13 W O 97/10107 PCT~US96/14700 re~erence numeral 12.1 to shGw the second layer 18 underneath.
The insignia 14 are intended to be observed by the eye. Thus, the transmissive layer 16 is in the ~orm o~
a transparent ~ilm, e.g. o~ a synthetic polymeric material, another kind o~ synthetic material, or the like.
The sheet 12 may be o~ paper or other material suitable to carry the insignia 14.
The transmissive layer 15 may adhesively be attached to the sheet 12, instead it may be heat sealed to the sheet 12, instead it may be bonded in any other convenient and e~Eective way to the sheet 12.
The bottom layer 18, in this embodiment, is merely a covering layer and can be o~ any convenient material. It may conveniently be o~ the same material as the transmissive layer 16. In other embodiments, ~or example where the sheet 12 carries insignia also on a rear thereo~, also the second or bottom layer 18 will be a suitably transmissive layer. Adhering the bottom layer 18 to the sheet 12 may be done similarly to adhering the transmissive layer 16 to the sheet 12.
In this embodiment, substantially all o~ the sur~ace area o~ the sheet 12 carries insignia and the whole CA 0223206~ 1998-03-13 W O 97/10107 PCTrUS96/14700 area o~ the sheet is to be regarded as a predetermined sur~ace portion in accordance with this invention. Thus, the whole o~ the sur~ace has been treated to be tamperproo~
in accordance with the invention.
In accordance with the invention, the bottom layer 18 and the sheet 12 have been severed by cutting as indicated by re~erence numeral 20 in ~ragments, more speci~ically elongate ~ragments lying obliquely across the com~osite article lC. The Iragments are retzined in their original positions and orientations, to ensure that the insignia 1~ are undisturbed, by means o~ the transmissive l~yer 15. From Figure 3, it can be appreciated that the cuts 20 enter the composite article 10 ~rom the rear and penetrate into the composite article 10 such that at least the bottom layer 18 and the sheet 1 are penetrated. In practice, the Applicant expects that it may be necessary to extend the cuts 20 also partially into the transmissive layer 16, but such that the cuts ,0 do not extend through the transmissive layer 16. The cuts 20 are numerous and closely spaced - generally much more so than shown diagrammatically in Figure 1 o~ the drawings.
Should there be an attempt to al~er the insignia 14, access to the insignia has to be obtained. Thus, in the area where an alteration is to be made, the .5 transmissive layer 15 or the second layer 18 will have to be removed or the sheet 1~ has to be split, or the like to CA 0223206~ 1998-03-13 W O 97/10107 PCT~US96/14700 render the insignia 14 accessible. Thus, also the retaining ~unction oc the transmissive layer 15 or the second layer i5 nulli~ied and the ~ragments are no longer held together and the document is e~ectively destroyed in the region attempted to be altered.
Similarly, oblique cuts 2~ are applied ~rom the top o~ the composite article 10 through the transmissive layer 16, through the sheet 12 and only partially into the bottom layer 18. This enhances the bene~icial e~ect o~
the invention in that even smaller fragments, e.g. in the rorm o~ small blocks as can be perceived f rom the centre portion o~ Figure 1 showing the sheet 12, are ~ormed. As can also be perceived best ~rom Figure 1, the cuts 20 are in parallel to one another, the cuts 22 are in parallel to one another and the cuts 20 and 22 are respectively transverse, more particularly at about right angles in this embodiment.
It is to be appreciated that the cuts 20 and 22, although they intersect, will not coincide ~or any appreciable distance.
With re~erence to Figure ~, basically the same composite layered article 10 o~ Figure 1 is shown and the same or similar re~erence numerals denote the same or similar components or ~eatures.
CA 0223206~ 1998-03-13 W O 97/10107 PCT~US96/14700 However, the cuts ~rom the second side are executed in criss-cross or chequered ~ashion as indicated at 20.1 and 20.2 respectively, in contrast to the parallel lines 20 o~ the Figure 1 embodime~t.
Similarly, the cuts ~rom the ~irst side are executed in criss-cross or chequered ~ashion as indicated at 22 1 and 22.2 respectively, in contrast to the parallel 7ines 22 o~ the Figure 1 embodiment.
It is very important that those cuts ~rom the ~irst and second sides which are parallel, are o~set with respect to one another such that,in the document 12 where all o~ the cuts are applied, the cuts 22.1 extend in between the cuts 20.1 and do not coincide with the cuts 20.1. Similarly, the cuts 22.2 extend in between the cuts 20.2 and do not coincide with the cuts 20.2. Thus, ~or example, each cut 20.1 in the article 12 is covered from above by means o~ a strip (which is transversely severed) o~ the transmissive layer 16 in between cuts 22.1 in the transmissive layer. Similarly, each cut 20.2 in the article is covered ~rom above by means o~ a strip (which is transversely severed) o~ the transmissive layer 16 in between cuts 22.2. Thus, no cut extends through the depth or thickness of the composite article 10, i.e. each cut is covered along one extremity o~ the cut by a strip o~
material either o~ the transmissive layer 16, or o~ the second layer 18. (It is to be appreciated that each o~ the CA 0223206~ 1998-03-13 W O 97/10107 PCTrUS96/14700 strips rererred to above is transverselv severed, i.e.
transversely to the respective cut in question). In this ~ashion, the ccmposite layered article 10 is held intact.
However, in accordance with the invention, should the composite article 10 be tampered with by removing a portion o~ the transmissive layer 16 cr o~ the second layer 18, or ir the layer 12 is split to gain access to the insignia 14, e.g. to e~ect alterations, such covering strips or portions are removed, causing the composite document 10 to ~ragmentize in the a~ected region which will render the tampering evident.
It is an advantage o~ the embodiment o~ Figure ~
that the integrity o~ the composite article 10 ayainst tampering is enhanced because the respective layers 6 and 18 are severed into blocks as opposed to merely strips, and the article 12 being protected is severed into blocks generally about one quarter o~ 'che size o~ the corresponding blocks o~ the Figure 1 embodiment.
I~ desired, a portion or portions o~ the document 12 may be lei~t uncovered, or may be le~t uncut 60 as not to inter~ere with operations e~ected by banks and the like, e.g. by means o~ magnetic or optical readers, or the like, used in the processing o~ cheques and other documents.
The Applicant is aware that there has been a steady increase in the number o~ incidences relating to CA 0223206~ 1998-03-13 ~raudulent alteration o~ negotiable documents or instruments such as cheques, bonds, share certilicates and the like by altering, ~or example, the name o~ the payee or the amount payable, or both. It is thus an advantage o~
the current invention that, inter alia, such negotiable documents can be rendered tamperproof to the extent that any attempt to tamper with the document is irreversibly exposed.

the invention in that even smaller fragments, e.g. in the rorm o~ small blocks as can be perceived f rom the centre portion o~ Figure 1 showing the sheet 12, are ~ormed. As can also be perceived best ~rom Figure 1, the cuts 20 are in parallel to one another, the cuts 22 are in parallel to one another and the cuts 20 and 22 are respectively transverse, more particularly at about right angles in this embodiment.
It is to be appreciated that the cuts 20 and 22, although they intersect, will not coincide ~or any appreciable distance.
With re~erence to Figure ~, basically the same composite layered article 10 o~ Figure 1 is shown and the same or similar re~erence numerals denote the same or similar components or ~eatures.
CA 0223206~ 1998-03-13 W O 97/10107 PCT~US96/14700 However, the cuts ~rom the second side are executed in criss-cross or chequered ~ashion as indicated at 20.1 and 20.2 respectively, in contrast to the parallel lines 20 o~ the Figure 1 embodime~t.
Similarly, the cuts ~rom the ~irst side are executed in criss-cross or chequered ~ashion as indicated at 22 1 and 22.2 respectively, in contrast to the parallel 7ines 22 o~ the Figure 1 embodiment.
It is very important that those cuts ~rom the ~irst and second sides which are parallel, are o~set with respect to one another such that,in the document 12 where all o~ the cuts are applied, the cuts 22.1 extend in between the cuts 20.1 and do not coincide with the cuts 20.1. Similarly, the cuts 22.2 extend in between the cuts 20.2 and do not coincide with the cuts 20.2. Thus, ~or example, each cut 20.1 in the article 12 is covered from above by means o~ a strip (which is transversely severed) o~ the transmissive layer 16 in between cuts 22.1 in the transmissive layer. Similarly, each cut 20.2 in the article is covered ~rom above by means o~ a strip (which is transversely severed) o~ the transmissive layer 16 in between cuts 22.2. Thus, no cut extends through the depth or thickness of the composite article 10, i.e. each cut is covered along one extremity o~ the cut by a strip o~
material either o~ the transmissive layer 16, or o~ the second layer 18. (It is to be appreciated that each o~ the CA 0223206~ 1998-03-13 W O 97/10107 PCTrUS96/14700 strips rererred to above is transverselv severed, i.e.
transversely to the respective cut in question). In this ~ashion, the ccmposite layered article 10 is held intact.
However, in accordance with the invention, should the composite article 10 be tampered with by removing a portion o~ the transmissive layer 16 cr o~ the second layer 18, or ir the layer 12 is split to gain access to the insignia 14, e.g. to e~ect alterations, such covering strips or portions are removed, causing the composite document 10 to ~ragmentize in the a~ected region which will render the tampering evident.
It is an advantage o~ the embodiment o~ Figure ~
that the integrity o~ the composite article 10 ayainst tampering is enhanced because the respective layers 6 and 18 are severed into blocks as opposed to merely strips, and the article 12 being protected is severed into blocks generally about one quarter o~ 'che size o~ the corresponding blocks o~ the Figure 1 embodiment.
I~ desired, a portion or portions o~ the document 12 may be lei~t uncovered, or may be le~t uncut 60 as not to inter~ere with operations e~ected by banks and the like, e.g. by means o~ magnetic or optical readers, or the like, used in the processing o~ cheques and other documents.
The Applicant is aware that there has been a steady increase in the number o~ incidences relating to CA 0223206~ 1998-03-13 ~raudulent alteration o~ negotiable documents or instruments such as cheques, bonds, share certilicates and the like by altering, ~or example, the name o~ the payee or the amount payable, or both. It is thus an advantage o~
the current invention that, inter alia, such negotiable documents can be rendered tamperproof to the extent that any attempt to tamper with the document is irreversibly exposed.
