Description

TECHNICAL FIELD [0001] The present invention relates to an apparatus and a method for providing service using high-performance iris recognition using a NAND memory,

More particularly, the present invention relates to an apparatus and a method for providing service using high-performance iris recognition using a NAND memory, and more particularly, The present invention relates to an apparatus and a method for providing a service using high-performance iris recognition using a NAND memory for performing various services.

Biometrics using biometrics is characterized by the fact that there is little risk of loss, theft, oblivion, and duplication due to external factors, and tracking of security breaches is possible. Such biometrics technologies are largely recognized as long-range, facial, vein, speech, retina, fingerprint, and iris recognition.

Among the biometric methods, long - term recognition, facial recognition, and vein recognition are not suitable for mounting in a wireless system because the recognition accuracy is high and the constant invariant principle can not be applied and the size of the apparatus can not be miniaturized.

Among the biometric methods, voice recognition uses voice or speaker verification (Speaker Verification System or Voice Print System) technique and can be easily recognized from a remote location. Therefore, it can be easily implemented in a wireless communication device equipped with voice communication . However, speech recognition is not recognizable when the user is relaxed, and the probability of error is high when recording or intentionally imitating the voice of the other person. Since the recognition rate is lowered due to the strong noise in the wireless environment, It is not suitable for practical use as a method of biometrics in a communication system.

In the biometric method, retina recognition uses the fact that the composition of the capillary vessels located on the back of the eye has the constant invariant characteristics. After reading the red light rays in the eye to read the pattern of the retinal capillaries, . Therefore, in order to recognize a successful retinal capillary pattern, eyeglasses must be removed and the eye focused to the point where the red light is reflected in the dark part of the circular cylinder of the eyepiece. Such retina recognition has the advantage of satisfying high security, but it has disadvantages such as not only inconvenience and uncomfortable use but also fear.

Among the biometric methods, fingerprint recognition utilizes a constant fingerprint that is formed by swelling of sweat glands and formed a constant flow, and there are optical and non-optical fingerprint recognition methods. The optical fingerprint recognition method includes a fingerprint recognition method using a prism and a fingerprint recognition method using a hologram. Non-optical fingerprint recognition methods include a fingerprint recognition method using a sensor array, a fingerprint recognition method using an electric field, (Ultrasonic Wave). Among them, the fingerprint recognition method applicable to a wireless communication system is a fingerprint recognition method using a non-optical sensor array and an electric field. However, the fingerprint recognition method is susceptible to static electricity and external shocks, is easily oxidized by chemical components in the body and air, And there is a drawback that the recognition rate increases when the sensor is buried.

Among the biometric methods, the iris recognition method uses a constant iris iris, which is formed before the age of 3 years after birth, and uses texture information such as iris pattern, shape, and color, Respectively. Since iris is located on the surface of the eye unlike the retina, it is not affected by diseases in the eye, it is not related to the redness of the eyes, and unlike the recognition of the retina in which the eye must be adhered to the eyedropper, Image information captured by a camera or a CCD camera can be easily processed through an image processing process.

In addition, the pattern used for iris recognition is more than 1078, which can be used as a complete biometric method than a fingerprint having about 1012 patterns. Various methods for fundamentally preventing iris scavenging through body damage and corresponding methods by detecting wavelengths generated in the eye using light emitting diodes and the like have been studied.
