  • Optical security system using fourier plane encoding
    Patent number: 8150033
    Abstract: A method of encrypting a set of data is disclosed. The method may include encoding a set of data with a first encryption key, and transforming the set of data encoded with the first encryption key. The method may also include using a second encryption key to encode the transformation of the set of data encoded with the first encryption key. The method may also include transforming the encoded transformation of the set of data encoded with the first encryption key generating thereby and encrypted set of data.
    Type: Grant
    Filed: October 4, 2007
    Date of Patent: April 3, 2012
    Assignee: University of Connecticut
    Inventors: Bahram Javidi, Ahouzi Esmail, Guanshen (Eric) Zhang
  • Optical security system using fourier plane encoding
    Patent number: 7684098
    Abstract: A system for encrypting a set of data may include a signal source, and a first, second, third, and fourth subsystem. The first subsystem may receive a first signal from the signal source and provide as output therefrom a first output signal. The second subsystem may receive a second signal from the signal source and provide as output therefrom a second output signal. The third subsystem may combine the first and second output signals. The fourth subsystem may acquire a set of encrypted data.

  • Optical security system using fourier plane encoding
    Patent number: 7428099
    Abstract: A method of verifying the authenticity of an object is disclosed. The method may include encoding a primary image, convolving the encoded primary image with a random code, generating thereby a first reference image, transforming the first reference image, and correlating the first reference image with a second reference image.

  • Optical security system using fourier plane encoding
    Patent number: 7095540
    Abstract: A method of verifying the authenticity of an object is presented. The method comprises providing a primary image; providing a secondary image; encoding the primary image; providing a random code; convolving the encoded primary image with the random code, providing thereby a reference image; affixing the reference image to the object to be authenticated; transforming the reference image; and comparing the transformed reference image with the secondary image. A system for verifying the authenticity of an object is presented. The system comprises a signal source; a first subsystem receiving a first signal from the signal source and providing as output therefrom a first output signal; a second subsystem receiving a second signal from the signal source and providing as output therefrom a second output signal; a third subsystem receiving the first and second output signals for comparing the first output signal with the second output signal.
