The invention relates to the field of the protection of security documents such as for example banknotes and identity documents against counterfeit and illegal reproduction. In particular, the present invention provides magnetic assemblies and methods for producing optical effect layers (OELs) on a substrate, said method comprising a step of exposing a coating composition comprising platelet-shaped magnetic or magnetisable pigment particles to the magnetic field of the magnetic assembly so as to bi-axially orient at least a part of the platelet-shaped magnetic or magnetisable pigment particles.

Magnetic assemblies and methods for producing optical effect layers comprising oriented platelet-shaped magnetic or magnetizable pigment particles

The invention relates to a security marking (), a method and a device for reading and decoding the security marking (), a security document () marked with the security marking (), and a method and a system for verifying and authenticating said security document (). The security marking () comprises a machine readable marking () overlapping with a magnetically induced layer () of a material including magnetically oriented reflective platelet-shaped magnetic or magnetizable pigment particles with two zones () and () of distinct orientations of the particles. The encoded data on the machine readable marking () being decodable only after the data separately read from the two zones () and () are gathered.

Processes for producing optical effect layers comprising oriented non-spherical magnetic or magnetizable pigment particles

The present invention relates to the field of protecting value documents and value commercial goods against counterfeit and illegal reproduction. In particular, the present invention provides processes for producing optical effect layers (OELs) comprising non-spherical magnetic or magnetizable particles and comprising a motif made of at least two areas made of a single applied and cured layer, said motif being obtained by using a selective curing performed by irradiation with an actinic radiation LED source (x) comprising an array of individually addressable actinic radiation emitters.

Device for producing optical effect layers

The present invention relates to the field of magnetic assemblies and processes for producing optical effect layers (OELs) comprising magnetically oriented non-spherical oblate magnetic or magnetizable pigment particles on a substrate. In particular, the present invention relates to magnetic assemblies processes for producing said OELs as anti-counterfeit means on security documents or security articles or for decorative purposes.

The invention relates to the field of the protection of security documents such as for example banknotes and identity documents against counterfeit and illegal reproduction. In particular, the present invention provides security documents and decorative articles comprising one or more optical effect layers (OELs) and methods for producing said OELs, said OELs comprising magnetically oriented platelet-shaped magnetic or magnetizable pigment particles in an at least partially cured coating layer (×10) and exhibiting an eye-catching optical effect thus allowing an observer to easily authenticate said OELs upon titling at viewing/observation angles between about −45° and about +45°.

Security documents or articles comprising optical effect layers comprising magnetic or magnetizable pigment particles and methods for producing said optical effect layers

The invention allows using a commodity hardware (e.g. a smartphone, a tablet, a computer . . . ) to automatically establish a high level of assurance authentication and identification of any government-issued identity document of a user (e.g. identity card, driving license, passport . . . ) and link that to digital identity counterpart. Moreover, the invention allows personalizing a material-based security feature provided of said government-issued identity document to create a link between the identity document and its data content that can be read by such a commodity hardware and serves as reliable credential for accessing a service once the material-based security feature has been authenticated via the commodity hardware and a signature of the identity data of the user has been authenticated by a server of an authority.

Verifiable access credential

The invention relates to a method of authenticating a magnetically induced mark applied on a substrate including magnetically oriented partially reflective platelet-shaped magnetic or magnetizable pigment particles, with a portable device equipped with a light source operable to deliver visible light, an imager, a processor and a memory, the method comprising calculating, with the processor, a corresponding average intensity I of the light reflected by the partially reflective platelet-shaped magnetic or magnetizable pigment particles and collected by the imager at corresponding viewing angle &#x3b8;, storing the calculated average intensities of the reflected light and corresponding viewing angles to obtain a reflected light intensity curve I(&#x3b8;), comparing the stored reflected light intensity curve I(&#x3b8;) with a stored reference reflected light intensity curve I(&#x3b8;) for said magnetically induced mark, and determining whether the magnetically induced mark is genuine based on a result of the comparison.
