  • Patent number: 9990040
    Abstract: A system performs haptic challenge-response functionality. The system generates one or more haptic effects, provides the one or more haptic effects as a haptic challenge question to a user via a haptic output device, and receives an answer from the user corresponding to the haptic challenge question. The system then determines, based on a model of human perception, whether the answer corresponds to a correct answer to the haptic challenge question. One embodiment predicts the correct answer to the haptic challenge question, compares the correct answer with the answer received from the user, and determines that the user is a human when the answer matches the correct answer. One embodiment repeats the generating, the providing, the receiving, the predicting, and the comparing when the answer does not match the correct answer.

  • Patent number: 7983455
    Abstract: A person making a handwritten signature performs a series of three-dimensional movements with a plane graphical finality. The movements generate kinetic information perceived by a special pen that the signature is performed with (the writing and digital acquisition device for the primary bio-kinetic information). The information, concordant to the afferent bio-kinetic pattern, is collected by included MEMS type acceleration sensors in the pen. The system analyzes the generated information (the signals) and determines the dynamic-biometrical characteristics based upon the biometrical dimension of the information. The characteristics are transformed into data vectors and invariants that are stored in a database. Based on algorithms, the system performs the required comparisons between the spatial kinetics of the specimens and the kinetics of the entrances and obtains distance-type answers. In statistical terms, the results are related to the entire subject database, by interpreting and sampling methods.

  • Patent number: 7646893
    Abstract: Every time to-be-verified biometric is input, the apparatus reflects the degree of fluctuation in the to-be-verified biometric information on narrowing down of registered feature information. After to-be-verified biometric information is input through the a biometric information input unit, the to-be-verified sub-feature information obtaining unit extracts two or more items of sub-feature information from the to-be-verified biometric information. Based on the pieces of to-be-verified sub-feature information, the to-be-verified sub-feature information assessing unit assesses an acquisition stability of each item of to-be-verified sub-feature information. According to the acquisition stability assessment, the registered feature information narrowing unit selects one or more pieces of registered feature information to be subjected to comparison/verification, thereby narrowing down the registered feature information.

    Abstract: A first light source has a first wavelength corresponding to an excitation wavelength of a fluorophore. The excitation wavelength and an emission wavelength of the fluorophore delineate a predetermined interval. A second light source has a second wavelength offset with respect to the first wavelength so as to be outside said predetermined interval. The offset between the first and second wavelengths is comprised between 30 nm and 100 nm. A camera comprises a filter opaque to the first and second wavelengths and transparent to the emission wavelength and to wavelengths substantially higher than the higher of the first and second wavelengths. The light sources and camera are synchronized to alternately activate one of the light sources and make the camera alternately acquire a fluorescence image and a background noise image.

  • Publication number: 20080152202
    Abstract: The invention refers to a computer-based system for the acquisition, analysis, and authentication of the handwritten signature. The person that performs a handwritten signature performs a series of three-dimensional movements with a plane graphical finality. The movements generate kinetic information perceived by the special pen that the signature is performed with (the writing and digital acquisition device for the primary bio-kinetic information). The information, concordant to the afferent bio-kinetic pattern, is collected by the included MEMS type acceleration sensors in the pen. The system continues to analyze the generated information (the signals) and it determines the dynamic-biometrical characteristics, based upon the biometrical dimension of the information. The characteristics are transformed in data vectors and invariants that are stored in a database.

  • Publication number: 20080059076
    Abstract: A method for classifying a plant leaf by utilizing the feature points of venation has been developed. A sample image of the venation can be extracted by utilizing a Curvature Scale Space (CSS) Corner Detection Algorithm. The sample image is treated to thicken the venation and increase the contrast through the retrieval unit prior to applying the Canny Edge Detection technology. The feature point, Branching Point and End Point is detected at each point where the calculated curvature angle is a local maximum. The distribution of the feature points of the extracted venation is calculated by applying a Parzen Window non-parametric estimation method.
