  • Patent number: 10147156
    Abstract: There are many advantages to implementing a watermark-based system using dedicated hardware, rather than using software executing on a general purpose processor. These include higher speed and lower power consumption. However, hardware implementations incur substantial design and development costs. Moreover, because each watermarking application has its own design constraints and parameters, it has not been cost-effective to develop a hardware chip design for each, since such chips would typically not be manufactured in volumes sufficient to bring per-unit costs down to an acceptable level. The present technology provides various techniques for making watermarking hardware adaptable, so that a single chip can serve multiple diverse watermark applications. By so-doing, the advantages of hardware implementation are made available where it was formerly cost-prohibitive, thereby enhancing operation of a great variety of watermark-based systems.

  • Patent number: 8360321
    Abstract: A method deconvolves a multiplexed fluorescence spectral signal into its component single-color fluorescence spectra emitted by contributing fluorophore types. A spectral database contains a parameter set for each of the component spectra. Optical codes are received as the multiplexed signals. A sliding window technique estimates a number and location of local peaks for the component spectra. Allowable variation ranges are assigned for the corresponding parameter sets. Each multiplexed signal is deconvolved into a sum of parametric values to generate a list of its component spectra. Encoded and received optical codes, in the form of multiplexed signals, are decoded and identified by their component spectra and contributing fluorophore types. A system for deconvolving the multiplexed signals includes a spectral database containing the parameter sets, a detection element receiving the optical codes, and a signal processor encoded to analyze and deconvolve the multiplexed signals.

  • Patent number: 8328102
    Abstract: Taggants can be incorporated into or onto value documents. The taggants comprise a crystalline taggant doped with two rare earth ions. The substrate or printed matter into which the taggant can be incorporated has a minimal absorption infrared wavelength window and the taggant is excited by incident infrared radiation in this wavelength range. Suitable first rare earth ions function as efficient broad band absorbers of incident infrared radiation and passes energy non-radiatively to a second rare earth ion, which emits infrared radiation at a wavelength greater than the incident infrared radiation. The emitted infrared radiation is also in the minimal absorption transmission window of the printed matter or the substrate into which the taggant is incorporated. Methods of authenticating the value document include detection of the emitted radiation at pre-determined values.
