KR20120070457A - The user recognition using iris recognition - Google Patents

Abstract

PURPOSE: A user recognition system is provided to increase recovery factors for loss materials by preventing other people from using a terminal by storing the iris information of a user. CONSTITUTION: A control apparatus(105) divides confirmation request copies captured by a camera(103) into original bands. The control apparatus compares the divided information with the stored original iris information. The control apparatus compares comparison concurrence rates with a standard rate. The control apparatus stores the original iris information again. A message output apparatus outputs an original iris storage message according to the control apparatus.

Description

The user recognition using iris recognition

Iris recognition technology

The present invention uses the iris recognition system and the iris recognition method to recognize the user using the iris recognition to identify the subject.

The iris recognition method uses a constant immortal iris that is formed before the age of three after a human is born, and uses texture information such as iris pattern, shape, and color, and has almost no false recognition rate and false rejection rate. Unlike the retina, the iris is located on the surface of the eye, so it is not affected by intraocular diseases, irrelevant to the redness of the eye, and unlike the retina recognition, which requires close contact with the eye, Image information captured by cameras or CCD cameras can be easily processed through image processing. In addition, the type of pattern used for iris recognition is 1078 or more, which may be used as a more complete biometric method than a fingerprint having a pattern type of about 1012.

Many technologies have already been developed and disclosed in connection with the iris recognition technology. By using this technology, a recognition terminal is attached to an electronic device to recognize a user.

Many electronic products of various functions and high performance are released. There are many expensive electronic devices. In particular, for example, the iPad and smartphone, because there are so many different functions, there are many cases of theft accidents, and many people use the functions without returning them even if they get lost products. These problems can be solved by attaching the above terminal.

In order to solve the above problems, the iris recognition terminal is attached to the electronic device. At this time, the iris recognition terminal recognizes the iris of the user of the electronic device in advance. Thus, the iris of another person other than the user is not recognized and cannot be used.

As described above, the present invention can obtain the effect of preventing theft of others through iris recognition.

Recognition is not possible even if someone learns electronic devices can be used, so even if you lose the electronic device is more likely to recover.

Attach the terminal to all electronic devices. The terminal includes a system for recognizing irises. After saving the user's iris capture in advance, the recognition system is set to operate whenever the user turns on the electronic device. Thus, the electronic device operates only when the user's iris and pauses. This system is a predesigned system.
