  • Patent number: 8391566
    Abstract: A method of identifying a person by his iris through determining an interior limit and using a predefined exterior limit to form an analysis zone. A code associated with the analysis zone is generated and compared with a previously generated reference code. If there is no match another predefined exterior limit is used. The process repeats as long as predefined exterior limits exist or until a positive match is made.

  • Patent number: 8345933
    Abstract: A procedure for identifying a person with a data acquisition device (202) that is configured for capturing the image of their eyelashes (102, 104). The captured image is compared with eyelash images in a database.

  • Patent number: 8314682
    Abstract: The invention concerns a biometric system provided with a set of reference biometric data (B?i) resulting from the application of a disjunction between a first set of biometric data (Bi) and a first encoded key (Ki), and from an information concerning the first key. A second set of biometric data (B2) is obtained. A second encoded key is determined by using a disjunction between the set of reference biometric data and the second set of biometric data. The second key is decoded by iterative decoding. Then, it is determined whether the first and second sets of biometric data mutually correspond by comparing the information concerning the first key with the second key.

  • Patent number: 8311290
    Abstract: A method for identifying a person (200) by capturing an image of the iris producing an anamorphic transformation of the image along a horizontal axis and then a vertical axis to code it in the form of one or two models. The model is compared with reference models stored in a database to determine the identity of the person. The acquisition device captures the image of the iris through means of optical deformation to produce the anamorphic transformation of the image and then codes the image into the models.

  • Patent number: 7978883
    Abstract: The present invention relates to a device (4) for positioning the face of a user relative to an image-capture apparatus (1), the positioning device comprising a picture-taking device (7) arranged to supply horizontally-reversed images, a display screen (5) for displaying the reversed images and connected to the picture-taking device, and means for superposing on the images displayed on the screen at least one positioning reference mark (6) for the user, the positioning reference mark and the displayed images lying substantially in the same plane. The invention also provides a corresponding method and image-capture apparatus.

  • Patent number: 7693307
    Abstract: The invention relates to an iris recognition method, comprising the steps of acquiring an image of at least one eye of a user in an infrared spectrum, and of processing said image to extract therefrom identification characteristics from the iris as defined by an outer boundary in the eye, the method comprising the steps of: acquiring an image of the eye in a visible spectrum substantially simultaneously with acquiring the image of the eye in the infrared spectrum; and prior to processing the infrared image, determining the outer boundary of the iris from the image in the visible spectrum. The invention also provides iris recognition apparatus.

  • Publication number: 20090161925
    Abstract: The invention concerns a method of acquiring the shape of the iris of an eye, comprising: a step of capture (112), by at least one image sensor, of at least one image of the iris, each image corresponding to the illumination of the iris by a light beam; a step of constructing (114) the three-dimensional shape of the iris from the image or images thus captured; and a step of verifying the non-flatness of the three-dimensional shape of the iris thus constructed.

  • Patent number: 7414737
    Abstract: A user positioning device comprising a stand (1) carrying two positioning markers (5) that are disposed so that each can be seen by a respective one of the eyes of a user, when the user is positioned correctly, and means (7) for forming a light path between each of the eyes of the user and the corresponding positioning marker, the light paths being optically separate from each other relative to the eyes of the user.
