Patent number: 11449590Abstract: Provided are a user authentication device and method based on iris recognition. The user authentication method includes: acquiring an image of a user's left and right eyes; extracting a pupil image and an iris image from the image; obtaining a first iris feature by analyzing the iris image; obtaining a second iris feature by analyzing the iris image and the pupil image; obtaining a similarity score based on the first iris feature, the second iris feature, and prestored reference iris data; and determining whether to approve user authentication based on the similarity score.Type: GrantFiled: November 23, 2018Date of Patent: September 20, 2022Assignee: Samsung Electronics Co., Ltd.Inventors: Gleb Andreevich Odinokikh, Aleksei Mikhailovich Fartukov, Vitaly Sergeevich Gnatyuk, Vladimir Alekseevich Eremeev, Juwoan Yoo, Kwanghyun Lee, Heejun Lee, Daekyu Shin

Patent number: 10445574Abstract: An apparatus for recognizing an iris is provided. The apparatus includes an image acquisition module configured to acquire a plurality of images, and a processor configured to select at least one image for iris recognition from among the plurality of images based on pupil information of each of the plurality of images, and recognize an iris in at least one image, wherein the pupil information includes at least one of information about a pupil radius and information about a pupil contrast.Type: GrantFiled: July 18, 2017Date of Patent: October 15, 2019Assignee: Samsung Electronics Co., Ltd.Inventors: Gleb Andreevich Odinokikh, Vitaly Sergeevich Gnatyuk, Aleksei Mikhailovich Fartukov, Vladimir Alekseevich Eremeev, Mikhail Vladimirovich Korobkin, Aleksei Bronislavovich Danilevich, Dae-kyu Shin, Ju-woan Yoo, Kwang-hyun Lee, Hee-jun Lee

Patent number: 10438061Abstract: A user recognition method that uses an iris is provided. The user recognition method includes generating a first mask for blocking a non-iris object area of an iris image, generating a converted iris image, in which the non-iris object area is blocked according to the first mask, generating a second mask for additionally blocking an inconsistent area, in which quantization results of the converted iris image are inconsistent, by adaptively transforming the first mask according to features of the converted iris image, obtaining an iris code by quantizing pixels included in the iris image, obtaining a converted iris code, in which portions corresponding to the non-iris object area and the inconsistent area are blocked, by applying the second mask to the iris code, and recognizing a user by matching a reference iris code, stored by the user in advance, to the converted iris code.Type: GrantFiled: July 5, 2017Date of Patent: October 8, 2019Assignee: Samsung Electronics Co., Ltd.Inventors: Mikhail Vladimirovich Korobkin, Vladimir Alekseevich Eremeev, Aleksei Mikhailovich Fartukov, Gleb Andreevich Odinokikh, Vitaly Sergeevich Gnatyuk, Aleksei Bronislavovich Danilevich, Dae-kyu Shin, Ju-woan Yoo, Kwang-hyun Lee, Hee-jun Lee
