The apparatus can comprise a generator operable to generate and sequentially direct a focussed noncoherent beam onto each of a plurality of different regions of the reading volume; a detector arrangement operable to collect a set comprising groups of data points from signals obtained when the beam scatters from the different regions of the reading volume, wherein different ones of the groups of data points relate to scatter from the respective different regions of the reading volume; and a data acquisition and processing module operable to determine a signature of the article from the set of groups of data points. | 06-24-2010 |
20100128510 | Magnetic Data Storage - The present invention can provide a magnetic memory structure comprising a column comprising a plurality of layers of magnetic material, each sized to adopt a single magnetic domain state, and a plurality of layers of non-magnetic material arranged as spacer layers between adjacent ones of the layers of magnetic material, such that successive magnetic layers in the column are magnetically antiparallel coupled. The column is arranged to maintain therein a plurality of stable transitions of an order parameter of the magnetisations between the magnetic layers, the transitions having a chirality. This enables a single magnetic column structure to store multiple data bits in such a way as to enable the bits to be propagated through the column to enable sequential reading and/or writing of data in the column. | 05-27-2010 |
20100124091 | Magnetic Data Storage Device and Method - A data storage device comprises an array of parallel magnetic nanowires each having a uniaxial anisotropy with an easy axis substantially perpendicular to the longitudinal axis of the nanowire and which is rotated about the longitudinal axis along the length of the nanowire, and a magnetisation state that follows the easy axis, where each nanowire has a data input element for nucleating magnetic domains separated by domain walls in an end of the nanowire, the sequence of domains and walls representing binary data, and a data read-out element operable to detect the magnetisation at an end of the nanowire, the device also comprising a magnetic field source operable to generate a magnetic field rotating in a plane substantially perpendicular to the longitudinal axes of the nanowires so as to propagate domain walls along the at least one nanowire. Reversal of the direction of rotation of the magnetic field reverses the propagation direction of the domain walls, so that data can be moved in either direction along the nanowires. | 05-20-2010 |
20100008590 | Signature of Moulded Article - A method of authenticating an article comprises generating a signature from intrinsic surface structure of an article, comparing the signature for the article to a stored signature for a mould used to produce articles, and determining an authentication result based upon a comparison result between the article signature and stored mould signature. | 01-14-2010 |
20100007930 | Authentication Scanner - A system for obtaining a signature from a scan area on the surface of an article comprises: a signature generator that generates the signature from scattered coherent radiation detected from a plurality of points on the surface and includes a scan head comprising a coherent radiation source and photodetectors; a camera for capturing an image of the surface; a comparator that compares the captured image with a reference image to determine the location and orientation of the scan area; and a drive assembly that positions the scan head appropriately for generating a signature from the scan area in response to the determination of the location and orientation of the scan area. | 01-14-2010 |
20090307112 | Two Tier Authentication - There can be provided a complete and flexible multi-tier article authentication system. A number of different authentication systems are applied to a given article in order to allow multiple levels of authentication to be performed by different persons throughout the supply chain, and using different levels of equipment to perform the authentication. By using such a flexible approach, authenticity can be verified to one or more different levels, depending upon the interest, capability and equipment of an individual. A corresponding method and apparatus can be provided. A tracking system based upon similar principles can additionally or alternatively be provided. | 12-10-2009 |
20090303000 | Linearisation of Scanned Data - A system for obtaining a signature a scan area on the surface of an article comprises: a signature generator that generates the signature from scattered coherent radiation detected from a plurality of regions on the surface by using relative motion between the article and a scan head comprising a coherent radiation source and photodetectors to obtain a set of data points comprising a group of data points from each region; an imaging detector that captures a sequence of images of the surface during the relative motion; and a processor that calculates the instantaneous velocity of the relative motion; whereby the signature generator uses the instantaneous velocity to linearise the groups of data point within the set of data points before generating the signature of the article from the set of data points. | 12-10-2009 |
20090290906 | Cartridges for Reprographics Devices - A removable cartridge for a reprographics device, such as a printer, is described. The removable cartridge comprises a signature scanning unit for use in generating a signature based upon an intrinsic characteristic of an article. By providing a signature scanning unit in a replaceable cartridge, few or no modifications to the existing designs of various reprographics devices are needed. Additionally, the installation of the signature scanning unit in a reprographics device is made as easy as replacing a standard removable cartridge, such as, for example, an inkjet or toner cartridge. The addition of authorisation/identification functionality to various conventional reprographics devices can also be made by a non-technical user using various embodiments of the invention. | 11-26-2009 |
20090283583 | Two Tier Authentication - There can be provided a complete and flexible multi-tier article authentication system. A number of implementation options are possible, and in one of which an article can include an applied code thereon, which applied code includes an identifier code for the article and a biometric type signature for the article, the biometric type signature having been generated from analysis of intrinsic surface or internal structure of a part of an article to which the applied code is applied. | 11-19-2009 |
20090016535 | Fuzzy Keys - A method can be provided for performing encryption using a fuzzy key. The method can comprise generating a message, dividing a fuzzy key into a plurality of blocks; and generating an encrypted message by selecting a block from the fuzzy key corresponding to a bit position or bit pattern in the message. | 01-15-2009 |
20080278998 | Data Storage Device and Method - A serial magnetic mass storage device and associated data storage method is provided based on magnetic nanowires that support single magnetic domains separated by domain walls. Each data-storing nanowire has a plurality of crossing nanowires along its length, forming cross junctions that constitute domain wall pinning sites. Data is fed through each data-storing nanowire by moving the magnetic domains under the action of a field that alternates between alignment and anti-alignment with the crossing nanowires. The data is encoded in the chirality of the domain walls, with up and down chirality transverse domain walls being used to encode 0's and 1's. Data is clocked into each nanowire with suitable nucleation generators capable of nucleating domains with domain walls of pre-defined chirality. Data is clocked out of each nanowire with suitable magnetic field sensors that sense the chirality. | 11-13-2008 |
