  • Patent number: 10313338
    Abstract: The present invention relates to an authentication method and device using a single-use password generated from iris image information. The device comprises: a terminal and a server storing, in respective memories thereof, the iris image information for authentication; a camera attached to and installed on the device to capture the iris image information for authentication; the terminal, which generates the single-use password from the iris image information acquired through the camera, and transmits the single-use password to the server; and the server, which has a built-in algorithm for comparing and determining whether or not the single-use password transmitted from the terminal matches single-use password stored in the server.

  • Patent number: 10152792
    Abstract: The present invention relates to a method and apparatus for identifying a living eye, in which IR LED lighting and lighting for varying the ambient illumination are installed on the front surface or one side of an iris recognition camera so as to determine whether an iris of an eye is an iris of a living eye when capturing an iris image by the iris recognition camera, using one or more criteria of whether the ratio of the sizes of the iris and pupil changes by the variation of the ambient illumination, whether the number or location of the IR LEDs focused on the iris and/or the pupil changes, whether the region of the iris image changes by eye blinking, and whether the direction of the gaze changes.

  • Patent number: 9087238
    Abstract: The present invention relates to an iris recognition device and method capable of improving iris recognition accuracy. To enhance iris recognition accuracy in consideration of variation in pupil size and iris region due to changes in intensity of lighting, the iris recognition device and method are configured to obtain multiple iris images having different iris sizes by capturing iris images of a person to be enrolled with a camera while adjusting brightness of lighting so that the iris size of the person to be enrolled varies from a maximum size to a minimum size, store the obtained iris images and associated iris size information for enrollment in a database interworking with the iris recognition device, and select enrolled iris images having an iris size most similar to that of an iris image captured by the camera for identification among many enrolled iris images for similarity measurement.

  • Patent number: 8433105
    Abstract: The present invention provides a method for acquiring region-of-interest and/or cognitive information from an eye image, comprising the steps of: preprocessing, standardizing, and coding the group of eye images for region-of-interest information or cognitive information to create eye image codes and to build a characteristic eye library in a memory in order to improve an iris recognition rate; grouping and partitioning or covering eye codes for eye images stored in the characteristic eye library into a plurality of groups, and obtaining a representative eye code of each of the eye code groups, preprocessing, standardizing, and coding a new eye image not assigned region-of-interest information or cognitive information in the same way as the above-described step to create a test eye code, matching the test eye image to the most similar eye image in the characteristic eye library, and transferring the region-of-interest information or cognitive information assigned to the matched eye image to the test eye image.

  • Patent number: 6247813
    Abstract: An iris identification system and method of identifying the identity of an animate being through iris scanning are disclosed. The system features an iris system pick-up unit including a camera for capturing iris images to create input image signals. The iris image pick-up unit is operated with a control unit that is interfaced with a data processing unit for preprocessing the input image signals into processed data. The processed data is representative of one of a plurality of parameters for iris identification selected from the group consisting of (1) the density and texture form of the iris fiber structure using a frequency transformation method, (2) pupilliary reaction, (3) the shape of the pupil, (4) autonomous nervous wreath reaction, (5) shape of the autonomous nervous wreath, (6) the existence of lacuna, (7) the location of the lacuna, and (8) the shape of the lacuna.
