Problems solved by technology

[0009] A disadvantage of the known methods of person identification is that, although the obtained codes contain information about more characteristic elements, they also contain redundant information since they are obtained from a single, practically independent space, This increases the overall code length and, as a result, increases the database retrieval time

Embodiment Construction

[0031] By means of exemplary embodiments, the essence of the claimed method is explained.

[0032] Example 1. In the most general case, the first identification method defined by claim 1 is implemented in the following way. Having the identified person within the field of view of the recording device allows obtaining a high quality color image of the iris of the eye. As such means, a color TV camera with digital output or a digital camera that allows pictures to be taken at small time intervals of the order of 0.001 seconds can be used. The images obtained were converted into digital form and transferred to a PC equipped with appropriate software (see WO / 03 / 053123). According to the image processing program, the PC based on the recorded color image forms a code, which is stored in the database as a reference code. Then, when there is a problem of identification of a person to allow access to or passage through protected areas such as some deposits, when crossing the state's ...

Abstract

The present inventions are aimed at improving accuracy and speed of identification. Said aim is achieved in that the method of person identification by an iris of the eye includes recording color image of an iris of the eye and its subsequent processing in several various spectral (color) ranges with forming an identification code by a wave length of an optical radiation reflected from each iris of the eye element; herewith, the fact of identification of a person is considered acknowledged in case of matching of the identification codes. Said aim is achieved in that the method of person identification by an iris of the eye includes recording color image of an iris of the eye in several spectral (color) ranges and its subsequent processing in the same various spectral ranges with forming an identification code by a calculated value of a wave length of an optical radiation reflected from each iris of the eye element; herewith, the fact of identification of a person is considered acknowledged in case of matching of the identification codes.

Description

technical field [0001] The present invention relates to a technique of preventing unauthorized individuals from accessing different objects by identifying the individual based on an image of the iris of the eye, and can be used for diagnosis of the state of an organ or a functional system in an organism based on the iris of the eye. Background technique [0002] There is known a method of identifying a person by an image of the iris of a person's eye, which method comprises recording images of the iris of the person's eye and forming a database based on them, which database is then used for person identification. The individual images before being loaded into the database undergo processing in a computer by means of specific software and are stored in the form of a data set. To achieve the process of identification of an individual, images of the iris of his eyes are recorded and stored, and fixed images are processed and compared with images stored in a database (WO03 / 04901...
