Abstract: An optical security device suitable for securing or authenticating high security or high value articles of manufacture when affixed thereto, is provided. The inventive security device produces optically variable effects when viewed from varying points of view and is made up of a microstructured layer having image icon elements that have at least one pigmented material. The microstructured layer is arranged relative to an arrangement of focusing elements such that at least portions of the image icon elements are observable through at least portions of the arrangement of focusing elements, thereby providing at least one synthetic image that demonstrates a color-transition effect as points of view from which the optical security device is viewed are changed. In one particular embodiment, the optical security device comprises (i) an arrangement of image icon elements having a first contrasting material pattern and a second contrasting material pattern; (ii) a fixed arrangement of focusing elements disposed relative to the arrangement of image icon elements such that the image icon elements project a synthetic image when viewed through the focusing elements, and having a first fixed org-pattern (as defined herein) that is mismatched from the at least one of the patterns of the first and second contrasting materials; where the synthetic image is a projection of both the first and second contrasting material when viewed from at least one angle.

Abstract: A security device that increases the number of design options available for a machine testable security feature formed in part from a light absorbing (e.g., magnetic) material, while more effectively hiding or concealing this material, is provided. The inventive security device achieves these results by physically separating this security feature from a visually detectable or public security feature. Also provided by way of this invention is a process for preparing the inventive security device as well as a security document that employs one or more such devices.

Abstract: A security thread for use in a paper-based value document, such as currency or banknote paper, includes a plastic substrate coated with one or more regions of "soft" magnetic material. A device for verifying both the authenticity and the denomination of the document includes a coil that is driven by an alternating current to thereby provide a uniform magnetic field within a predetermined spatial region. As the document passes in proximity to the drive coil, the applied magnetic field saturates the regions of magnetic material on the security thread. The magnetic regions provide a response magnetic field that, because of the saturation of the magnetic regions, is a non-linear response containing a multiple of frequency components, including a component at the fundamental or drive frequency and various harmonic frequency components. A receive coil senses the response magnetic field. A signal processor connected to the receive coil utilizes the response signals at the fundamental frequency and the low-order harmonic frequencies to determine both the type of magnetic material on the security thread and the denomination of the document from the spatial distribution of the magnetic regions on the security thread.
