Abstract:
A method for creating a secure document, registering the secure document and verifying the authenticity of the secure document includes receiving a print object that has content. A security feature, including an identifier, is created and is associated with the content. The identifier may be a barcode. The barcode may represent a character string. The security feature may include the identifier barcode and a decoy barcode that is not associated with the content. The identifier barcode (or the character string represented by the barcode) and the content are transmitted to a database for storage. Once stored, the identifier and the content are considered to be registered. A print object that includes the security feature and the content is then transmitted to a printer for printing.
Abstract:
Die Erfindung betrifft ein Verfahren zur Überprüfung der Echtheit eines Dokumentes unter Verwendung zumindest einer Zusatzinformation, wobei das Dokument ein Informationsmerkmal aufweist, welches auf die Zusatzinformation hinweist, mit: Erfassen (401) einer Abbildung des Dokumentes; Erfassen (403) des Informationsmerkmals in der erfassten Abbildung; Bestimmen (405) der Zusatzinformation auf der Basis des erfassten Informationsmerkmals; und Anzeigen (407) der erfassten Abbildung gemeinsam mit der Zusatzinformation, um die Echtheit des Dokumentes zu überprüfen.
Abstract:
First and second patterns are formed on a substrate. A spatial offset between the patterns is determined, and stored for later use in authenticating the substrate. (One or both of the patterns may convey steganographic information. One pattern may be printed, while the other may be embossed.) A smartphone can sense these patterns, determine the spatial offset, and check whether the determined offset matches the earlier- stored offset, to judge whether the substrate is authentic. Another arrangement effects serialization of product packaging by use of paired patterns (at least one of which is typically a steganographic watermark pattern) applied in a manner causing a spatial offset between the patterns to progressively vary along a length of a printed web. Still other arrangements involve substrates conveying patterns that degrade over time, e.g., indicating freshness or pressurization condition. A great variety of other features and arrangements are also detailed.
Abstract:
Disclosed is a device for the authentication of an optically variable entity exhibiting a color shift with changing viewing-angle, the device comprising a plate of light-refractive material, said plate having two surfaces and an array of light-refracting protrusions or recesses on at least one of said surfaces, and being disposed in said device such as to provide, aside each other, a direct view and a view through said plate onto at least parts of said optically variable entity, said view through said plate being an angularly deflected view, resulting from light refraction at said protrusions or recesses. Further disclosed is a method for authenticating an optically variable entity, as well as the use of a plate having two parallel surfaces and an array of positive or negative light- refracting protrusions or recesses on at least one of said surfaces for authenticating an optically variable entity.
Abstract:
Die Erfindung betrifft ein Wert- und/oder Sicherheitsdokument (1) mit mindestens einer Linie (3), beispielsweise in Form eines Guillochenmusters, wobei die Linie eine Linienbreite (b) aufweist, wobei die Linie (3) zumindest in einem Teilbereich (4) geteilt ist, so dass ein Zwischenraum (Z) mit einer Breite (b z ) entsteht, wobei in dem Zwischenraum (Z) eine erste Information codiert wird und wobei der Zwischenraum (Z) nicht mit bloßem Auge sichtbar ist
Abstract:
The present invention relates to the technical field of devices for reading/authenticating banknotes. The invention also concerns handheld devices, particularly those which may be used by visually impaired persons, to identify different banknote denominations. The present invention is aimed at providing a banknote validator that avoids the drawbacks of the prior art. The validator according to the invention may as well be used for validating a security document including a marking (like luminescent ink or pattern printed on said document, luminescent security thread or strip, for example) operable to glow with a specific color luminescence under appropriate UV light illumination. The invention further describes a method for identifying a denomination of a banknote having a test zone including a marking operable to glow with a specific color luminescence according to the denomination under appropriate UV light illumination.
Abstract:
An embodiment relates to a man-made object comprising a distinctive structure with a feature to identify the object, wherein the object has a size such that the object is observable under visible light, wherein the feature is embedded in or on the object and a size of the feature is such that the feature is not observable under visible light, wherein the feature comprises an attribute originating from the feature, and wherein the attribute defines the feature.

Abstract:
Microlens sheetings with different types of composite images are disclosed, in which the composite image floats above, in, or below the sheeting, or some combination. One type of composite image may be viewable to the unaided eye or an observer and another type of composite image is viewable only to the aided eye of an observer. Methods for providing such an imaged sheeting are also disclosed.
