Abstract
A security device includes an array of image icon elements and an array of image icon focusing elements, wherein the array of image icon elements and the array of image icon focusing elements are disposed relative to each other such that the security device projects a synthetic image along a viewing angle and wherein the security device is configured to physically degrade when exposed to temperatures above an anti-harvesting temperature, the anti-harvesting temperature being lower than a harvesting temperature of a coupling between the security device and a substrate.
Claims32
A security device comprising:
- an array of image icon elements;
- and
- an array of image icon focusing elements,
- wherein the array of image icon elements and the array of image icon focusing elements are disposed relative to each other such that the security device projects a synthetic image when the array of image icon elements is viewed directly or through the array of image icon elements, and
- wherein the security device thermally decays when exposed to temperatures at or above an anti-harvesting temperature, the anti-harvesting temperature being lower than a harvesting temperature of a coupling between the security device and a substrate.
A security label comprising:
- a label substrate;
- and
- a security device affixed to a product substrate by a first coupling, the product substrate affixed to the label substrate by a second coupling, and
- wherein the security label thermally decays when exposed to temperatures at or above an anti-harvesting temperature, and
- wherein the anti-harvesting temperature is lower than a harvesting temperature of the first coupling.
A secure document, comprising:
- a product substrate;
- and
- a security device affixed to the product substrate by a first coupling, and
- wherein the security device thermally decays when exposed to temperatures at or above an anti-harvesting temperature,
- wherein the anti-harvesting temperature is lower than a harvesting temperature of the first coupling.
A method of producing a security device, comprising:
- providing an array of image icon elements;
- providing an array of image icon focusing elements;
- providing at least one anti-harvesting component which thermally decays at temperatures at or above an anti-harvesting temperature;
- and
- wherein the array of image icon elements and the array of image icon focusing elements are coupled to produce at least one synthetic image.
A method of producing a security label, comprising:
- providing a security device, the security device comprising an array of image icon elements, and an array of image icon focusing elements, wherein the array of image icon elements and the array of image icon focusing elements are disposed relative to each other such that the security device projects a synthetic image along a viewing angle, and wherein the security device thermally decays when exposed to temperatures at or above an anti-harvesting temperature;
- and
- affixing the security device to a label substrate to a label substrate by a first coupling, and
- wherein the anti-harvesting temperature is lower than a harvesting temperature of the first coupling.
