Abstract: 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°.

Abstract: 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 θ, storing the calculated average intensities of the reflected light and corresponding viewing angles to obtain a reflected light intensity curve I(θ), comparing the stored reflected light intensity curve I(θ) with a stored reference reflected light intensity curve Iref(θ) for said magnetically induced mark, and determining whether the magnetically induced mark is genuine based on a result of the comparison.

Abstract: A method of authenticating a product by taking an image of the product and comparing the image with a reference image of a genuine product taken previously to determine if the products in the two images are the same. The two images are captured under substantially similar conditions so that the two images are as similar as possible prior to the comparison. The two images are processed in order to calculate for each of them a list of significant points. The significant points are compared to determine a degree of correspondence between the significant points. An answer is output indicating the authenticity of the product based on the degree of correspondence. Some of the matching significant points may be used to define a common coordinate system for the two images. The two lists of significant points may be compared in this common coordinate system.

Abstract: An optical security element made of a refractive transparent or partially transparent optical material and comprising an optical assembly of a caustic layer having a light-redirecting surface with a relief pattern of given depth and a focal length fC and an adjacent lens element of focal length fL configured to redirect incident light received from a point-like light source through it and to form a projected image containing a caustic pattern directly on a retina of an observer. A marked object, as well as a method of visually authenticating an object, and use of optical security elements for authenticating or securing against counterfeiting are also disclosed.

Abstract: Method for authenticating a timepiece comprising measuring acoustic vibrations emitted by said timepiece to obtain an electrical signal indicating magnitude information comprising a variation of a magnitude of the measured acoustic vibrations as a function of time. The electrical signal comprises at least one specific tone associated with the presence of a quartz resonator in the timepiece. Method further comprises performing transform of electrical signal into frequency domain to obtain frequency-domain power spectrum indicating variation of power of electrical signal as function of frequency, processing the frequency-domain power spectrum so as to reveal at least one narrow peak in frequency-domain power spectrum corresponding to the at least one specific tone, and extracting at least one resonance frequency corresponding to said at least one narrow peak. Method further comprises comparing extracted at least one resonance frequency with at least one reference resonance frequency; and determining an authenticity of said timepiece.
