摘要： Holographic and diffractive security devices and documents carrying security devices as well as system, apparatus, and method for making and using security devices. Security devices (104) provide at least one type of security feature in form of secret, hidden, or covert security feature (108), not visible to a normal unaided human eye. Covert security features may be any graphic or symbolic representation. One or multiple security features may be provided on any single security device in any combination. Covert feature is revealed either when a decoder device (103) is used with the security device, or when the security device is oriented and viewed in predetermined manner. Embodiments may provide a second overt or non-covert security device in the form of a diffractive or holographic image or graphic (109) that is visible to the unaided eye without use of any decoder or special viewing conditions.

摘要： A multi-spectral holographic security marker is made by a novel method according to the invention involving a replay frequency shift to one or more final replay frequencies of a part or parts only of a recorded image plane volume hologram. The marker comprises an optional surface hologram and an image plane volume hologram. The volume hologram is divided into discrete areas which have mutually different final replay frequencies. The security information carried by the marker is a combination of the size and shape of those different replay areas together with the hologram content itself which is spread across the different replay areas. If the marker also includes a surface hologram, then that is preferably aligned with the junctions between the replay areas. Preferably one volume hologram replay frequency is in the visible spectrum and the other is in the invisible part of the spectrum (IR or UV).

摘要： This invention generally relates to methods and apparatus for verifying data, and more particularly to holographic data carriers and apparatus for creating such data carriers, and to methods of verifying data stored on holographic data carriers. A data carrier comprising: a hologram storing data to reproduce an image of a portion of a human body characteristic of an individual; and a second data bearing device; and wherein data stored by said second data bearing device is verifiable using data stored in said hologram.

摘要： The invention relates to an encrypted synthetic hologram formed from the Fourier transformation of an image (40) and consisting of a matrix of elementary cells. Half of the elementary cells, with a 10% margin, selected according to a motif (52), are dephased in relation to the elementary cells of a hologram directly produced by the Fourier transformation of the image.
