Authentication system using biometric information and screen golf system using it {AUTHENTICATION SYSTEM USING BIO-INFORMATION AND SCREEN GOLF SYSTEM USING THE SAME}

The present invention relates to an authentication system using biometric information and a screen golf system using the same. More specifically, it does not need to remember an ID or password, and thus, uses biometric information that can conveniently and reliably block leakage of user's personal information. It relates to an authentication system and a screen golf system using the same.

In today's information society, certification of individuals is required in various fields. In particular, the need for authentication of a user is increasing in a system providing a predetermined service to the user. For example, a user who uses portal services such as Naver, Gmail, Daum, etc., visits the Internet site of the service and enters their ID and password to complete the authentication of the user. Various services such as e-mail can be used.

The most common method of authenticating a user as above is to enter the user's ID and password. However, the authentication method using the ID and password has a problem that personal information can be abused by leaking the ID and password to others through hacking. In addition, in recent years, a single user uses a plurality of sites, but once an ID and password are leaked, a large amount of damage may occur at a number of sites to which the user is subscribed. Of course, a user may set different IDs and passwords in different sites, but it is virtually impossible to remember all the IDs and passwords of each of the multiple sites.

Therefore, there is a need for the development of an authentication system that does not need to be memorized directly by a user, and at the same time, there is no fear of leaking to others. In particular, simulating devices that can enjoy sports games without going out to the field by using three-dimensional stereoscopic image and computer simulation technology have recently been developed, the need for user authentication in such sports sports simulation devices It is strongly demanded. For example, in the case of screen golf targeting golf, since golf is not a group game but an individual record game, it is necessary to store a record played by the user and view it whenever the user wants. To this end, it is necessary to verify the identity of each user playing screen golf, so user authentication is required.

The present invention has been invented in view of the above circumstances, and provides an authentication system using biometric information that can conveniently and reliably block leakage of user's personal information without having to remember an ID or password, and provides a screen golf system using the same. It aims to do it.

An authentication system using biometric information according to an embodiment of the present invention for achieving the above object includes an authentication unit, an authentication device, and a service providing unit. The authentication unit authenticates the user by using the iris as the authentication information. The authentication device obtains the authentication information from the user. When the authentication is completed based on the authentication information in the authentication unit, the service providing unit provides a predetermined service to the user. The authentication device is provided in a mobile device or a head-mounted type device.

In addition, the screen golf system according to an embodiment of the present invention includes an authentication unit, authentication device and service provider. The authentication unit authenticates the user by using the iris as the authentication information. The authentication device obtains the authentication information from the user. The service provider provides a screen golf service to the user when authentication is completed based on the authentication information in the authentication unit. The authentication device is provided in a mobile device or a head mounted device.

In the screen golf system, the head-mounted device may be an augmented reality display device that shows information about the screen golf to a user.

In the screen golf system, the information about the screen golf shown to the user in the head-mounted device may include a mini-map for the golf course.

In the screen golf system, when there are a plurality of users, the authentication unit performs authentication for each of a plurality of users, and when the authentication is completed, a window for each of the plurality of users is displayed on the screen of the screen golf. I can display it.

In the screen golf system, the authentication device may comprise an infrared light source and an infrared camera.

1 is a schematic configuration diagram of an authentication system using biometric information according to an embodiment of the present invention.

Referring to FIG. 1, the authentication system 1 includes an authentication unit 10, a service providing unit 20, and an authentication device 30, which may be connected to each other in a wired or wireless manner by a communication network. For example, the authentication unit 10 and the service provider 20 may each include an Internet server, and the authentication device 30 may be configured as a device that can be connected to the Internet server or the authentication unit 10. B may be configured as a device that can directly transmit and receive data with the service provider 20. As described above, the authenticator 10, the service provider 20, and the authentication device 30 may be connected to each other to exchange information necessary for authentication.

The authentication unit 10 may perform authentication for a user before providing a predetermined service desired by the user, and may include a database 11 that stores information necessary for authentication during authentication. The service provider 20 is to provide a predetermined service desired by the user after authentication is completed. For example, a service for playing a virtual indoor sport such as screen golf or screen baseball, which is widely used as an indoor sport, is widely used. Can be provided. The authentication device 30 is responsible for obtaining information necessary for authentication from the user and transferring the information to the authenticator 10 or the service provider 20. As the authentication device 30, a mobile device can be used, for example, a mobile device such as a mobile phone owned by the user can be used. Alternatively, in consideration of the case where the user does not have a mobile device, a separate device provided in the service providing unit 20 may be used as the authentication device 30.

The authentication system 1 of the present invention performs authentication using user biometric information, for example, information on an iris. The principle and process of iris authentication are as follows.

FIG. 2 is a diagram schematically illustrating the structure of a human eye, and FIG. 3 is a flowchart schematically illustrating a process of performing iris authentication in the authentication system of FIG. 1.

Referring to FIG. 2, the human eye is located on the outermost surface of the cornea that protects the eye from the outside and passes and refracts light. In the inner center of the cornea is the pupil, which determines the amount of light that enters the eye, depending on its size. The iris is a donut-shaped membrane around the pupil that adjusts the pupil's size through contraction and relaxation. Adjust

The human iris is completed after about 18 months of age, and after completion, it has a characteristic of not changing for life. That is, the iris pattern raised near the inner edge of the iris hardly changes once determined, and since the shapes are different for each person, it can be usefully used as information for recognizing a person. In particular, compared to the fingerprint used in the past as a biometric means of humans, the iris has more unique patterns than the fingerprint, and can be accurately recognized even if wearing glasses or lenses, there is a non-contact method has no advantage of rejection .

Looking at the process of recognizing and authenticating a user using the iris, as shown in FIG. 3, first, an image of an eye is captured and acquired (S10). In this embodiment, the authentication device 30 is used to acquire an image of the eye, for which the authentication device 30 is provided with a light and a camera. Since the iris is well identified by near infrared, the illumination is preferably an infrared light source and the camera is an infrared camera.

Next, an iris image is extracted from the captured eye image (S20). Since the iris is formed in a ring shape around the pupil, in this step, a ring-shaped portion around the pupil is extracted from the captured eye image.

Next, the portion irrelevant to the iris (named 'noise' for convenience) is removed from the extracted iris image (S30). Eyelids and eyelashes are located in the vicinity of the iris, and in particular, such as eyelashes may overlap with the iris in the obtained iris image. Therefore, it is necessary to remove such noise so that only the iris image remains.

Next, the iris image from which the noise is removed is detected and dataized (S40). For example, an iris image is normalized, the image pattern is detected, and encoded to be stored in a database for data. In order to increase the accuracy of iris authentication, the iris image is preferably at least 200 pixels or more.

Finally, if the iris image data obtained in the data encoding step is obtained for the first time for the user, it is stored in the database DB as it is. In addition, when the iris image data obtained in the data encoding step is authentication iris image data for authenticating the user, the user authentication is performed by comparing the iris image data with data stored in the database DB (S50).

Since the processing speed for the above iris authentication takes only a few seconds (up to about 2 seconds), iris authentication can be used more easily than fingerprint recognition, which has been widely used in the past. It can be applied in various ways such as e-commerce authentication. In addition, the iris authentication is convenient because it does not need to remember the ID when compared to the conventional ID or password method, but at the same time it is impossible to authenticate itself without the user himself, there is an advantage that it can reliably block the theft or forgery of others. .

4A and 4B schematically illustrate a mobile device as an example of the authentication device of FIG. 1 and a method of acquiring an iris image using the same.

1 and 4A, a mobile device 30a such as a user's mobile phone may be used as the authentication device 30. The mobile device 30a is provided with a light source 31 and a camera 32 to acquire an iris image. Since the iris is well identified in the near infrared, the light source 31 is preferably a light source capable of irradiating infrared rays of approximately 720-900 nm wavelength, and the camera 32 can capture an object in the infrared ray of the wavelength range. It is preferable that it is an infrared camera.

When the user wants to acquire the iris image of the user using the mobile device 30a, the user himself properly positions the position of his eye on the path through which the light from the light source 31 passes and the photographing position of the camera 32. In, by pressing the shooting button of the mobile device (30a) with a finger to take a picture of the eye through the camera 32. Recently, a smartphone is mainly used as a mobile phone. In the case of a smart phone, a button-shaped picture may be displayed on a display screen instead of a separate physical button. In particular, the smart phone may be installed with software to utilize various functions of the smart phone. In this embodiment, the software that can be interlocked with the authentication unit 10 or the service provider 20 is installed in the smart phone, and the user When the iris image is photographed, the software may be configured to transmit the photographed image to the authenticator 10 or the like.

As described above, in the case of using the mobile device 30a, in addition to the effect of iris authentication to reliably block the leakage of the user's personal information, it is easy to use a mobile phone held by the user even without a separate authentication device. The advantage is that authentication can be performed.

5 is a diagram illustrating a schematic structure of a screen golf system according to an embodiment of the present invention to which an authentication system using biometric information is applied.

The authentication system using the iris described above may be applied to a screen golf system that provides screen golf in a service provider. That is, in the present embodiment, the user's login and the like required before the screen golf is performed using the authentication system using the iris described above, and when the authentication is completed, the related service is provided so that the user can play the screen golf.

Referring to FIG. 5, in the booth providing the screen golf service in the screen golf system 100, the hit plate 110, the detector 120, the input unit 130, the controller 140, the display unit 150, and the like are provided. It is provided.

The striking plate 110 corresponds to a striking zone where a real golf ball (RB) is placed and the striking is made. A striking mat 111 is installed on the striking plate 110, and an auto tee 112 is provided on the striking mat 111 to move up and down, so that a golf ball for striking the user through the auto tee 112 is formed. RB) is provided.

The detection unit 120 detects the movement of the golf ball hit by the user, and to grasp the overall state information about the hit golf ball, as well as a camera that can capture the movement of the golf ball (RB) as well as the golf ball Any sensing means such as a sensing sensor can be used as long as the movement of the RB can be detected. The camera or the sensor may be used alone or used together, and only one may be used or several may be used if necessary.

The input unit 130 is for receiving various information from a user, and a keyboard or a mouse may be used. In screen golf, when the user inputs his or her ID or password, the user may input information from the user, such as when the user selects a golf course or difficulty to play. It is provided. However, in the present embodiment, since the user authentication is performed using the iris, the input unit 130 may not be necessary for the purpose of inputting an ID or a password. In addition, when a mobile device such as a user's mobile phone 30a (see FIG. 4A) is used as an authentication device during iris authentication, by installing an appropriate application program on the mobile phone, the mobile phone can select a golf course or difficulty level. The need for the input unit 130 is not high. However, since a user without a mobile phone or a mobile phone cannot be used (eg, a battery is discharged or a mobile phone is broken) may occur, the input unit 130 is still required for such a case.

When the user hits the golf ball RB, the controller 140 receives the overall state information on the hit golf ball RB, and then simulates the trajectory of the golf ball RB based on the simulation. Operate to be provided.

The display unit 150 includes an image processing unit 151 and a screen 152. The image processing unit 151 processes and provides a related image such that the virtual golf course and the virtual golf ball are displayed on the screen 152, and may include a device such as a beam projector. The screen 152 displays a golf-related image and shows it to the user. There are various areas in the virtual golf course displayed on the screen 152 as in the actual golf course. For example, a virtual golf course may include fairways, roughs, bunkers, water hazards, and the like. Although not shown in FIG. 5, a voice processing unit and a voice output unit may be provided to guide the user of the progress of the game and provide various sound effects according to the progress of the game.

6 is a diagram illustrating a screen displayed on the screen of FIG. 5.

Referring to FIG. 6, the screen 152 may display windows 153, 154, and 155 of a user currently receiving a service along with a golf course screen for each user. In general, screen golf is often played together by a party rather than alone, and when several users want to play screen golf, each user shoots his iris with his mobile phone to be authenticated. When the authentication is completed, the windows 153, 154, and 155 for each user are displayed on the screen 152. In the case of multiple users logging in using a conventional ID and password method, since one input device per booth of a screen golf is normally installed, the back person must wait until the front person inputs the ID and password to complete the authentication. In the case of iris authentication, it is convenient to be able to authenticate at the same time with their cell phone without having to wait for several people.

Although the above-mentioned embodiment uses a mobile device as an authentication device for iris authentication, the authentication device is not limited to the mobile device. For example, an iris scanner may be provided at a place providing screen golf to acquire an iris image without using a mobile device. Alternatively, a device such as described below may be used.

7 is a diagram schematically showing a head mounted device as another example of an authentication device.

Referring to FIG. 7, in this embodiment, a device capable of acquiring an iris image from a user in a state of being attached to a user's body is used as an authentication device. For example, a head-mounted type device 30b such as glasses may be used as the authentication device, and other types of wearable devices may additionally or alternatively be used.

The head mounted device 30b includes a lens 35 and frames 36 and 37 similar to glasses, but since the device 30b does not play a role in improving vision, it is essential that the lens 35 is essential. (However, in the embodiments of FIGS. 8 and 9 to be described later, the lens 35 is required). The frames 36 and 37 include a center frame 36 and a side frame 37 as in normal glasses. In the center frame 36, a light source 31 and a camera 32 are installed to acquire an iris image. Since the iris is well identified in the near infrared, the light source 31 is preferably a light source capable of irradiating infrared light of approximately 720-900 nm wavelength, and the camera 32 is an infrared camera capable of shooting an object in the infrared ray of the wavelength range. Is preferably. Although not shown in FIG. 7, the head mounted device 30b according to the present embodiment includes a switch for turning on and off an operation unit (for example, a light source 31 for operating the light source 31 and the camera 32). Or a photographing button of the camera 32), a power supply unit such as a battery for supplying electricity, and a transmission unit for transmitting the photographed iris image to a peripheral device using wired / wireless communication or the like.

The light source 31 and the camera 32 are configured to be disposed at an optimal position for capturing the iris in the center frame 36. In other words, even if the user does not perform any other operation (in the case of a mobile device, the user needs to properly position the camera component of the device in order to photograph the iris), but the user may not normally operate the head mounted device 30b. The light source 31 and the camera 32 may be disposed at an optimal position for capturing the iris without further adjusting the position just by wearing them in the position.

Even when using the head mounted device 30b as shown in FIG. 7 as the authentication device, the structure of the screen golf system using this authentication device is not significantly different from the structure shown in FIG. However, in the case of using a mobile device, the input unit 130 has not been described in the foregoing, but in the case of using the head mounted device 30b, the input unit 130 for inputting user information or a golf course desired by the user is described. It can be said that the need for. In addition, the mobile device may immediately transfer the photographed iris image information to the authenticator, but the head mounted device 30b may transmit the image to the authenticator through the service provider. For example, by connecting a wire such as a USB cable to the head-mounted device 30b or using wireless communication, iris image information captured by the service provider is transferred (for example, to the controller 140 shown in FIG. 5). And then finally reach the authenticator.

8 and 9 are diagrams illustrating examples of providing various additional information through the head mounted device of FIG. 7.

In addition to the first function of acquiring an iris image for user authentication, the head mounted device 30b according to the present exemplary embodiment may allow the user to perform a second function of providing various beneficial information in playing screen golf. . For example, the head mounted device 30b may be configured as an augmented reality display device to show a user a minimap of a golf course he is playing.

Mini-Map is often used for gamers' convenience in computer games, and it is a miniature map of the place where the game is going. helpful. In general, a golf game is played by hitting a golf ball from the tee box to the green and putting the golf ball into the green's hole cup. The distance from the tee box to the green's hole cup is quite far. It is separated (depending on the course, about 300-400m for par 4). In screen golf, only a limited area is displayed, focusing on the point where the golf ball is placed on the screen. From the user's point of view, how is the entire golf course, and the position of the golf ball that he hits corresponds to some extent in the whole golf course. You will be curious about the question. This curiosity can be easily solved by miniaturizing the entire golf course and displaying a minimap displaying the location of the golf ball. Therefore, the introduction of the minimap in screen golf is very beneficial.

In the head mounted device 30b according to the present embodiment, a display, which is an augmented reality for a golf field, may be implemented through a lens. Specifically, the entire minimap (FIG. 8) representing the entire virtual golf course may be shown to the user through the lens, or the partial minimap (FIG. 9) representing a part of the virtual golf course may be shown. In addition, when the user wants, the minimap can be switched from the full minimap to the partial minimap or from the partial minimap to the full minimap according to the user's choice.

The display appearing on the lens may be represented by light projected from a light projection projector, or other types of display elements may be used, for example the lens itself may comprise a transparent or translucent matrix display such as a liquid crystal display. Can be. In this case, an augmented reality in which the front object is projected through the lens and the image provided from the projector is projected to simultaneously project the virtual reality and the real world can be realized.

As shown in FIG. 8, the overall outline of the golf course of the hole can be easily grasped through the entire minimap, and the hole cup (HC), fairway (F; fairway), and rough (R) of the course can be easily understood. Rough), it is easy to see where Green (G) is placed. In addition, a virtual golf ball (VB) may be displayed on the entire minimap. The trajectory of the virtual golf ball is simulated on the virtual golf course based on the golf ball hit by the user currently playing, and the mini golf ball corresponds to the point where the virtual golf ball is located according to the simulated result on the virtual golf course. The virtual golf ball VB is located on the map. Therefore, the user can see the golf ball (VB) on the mini-map, and can determine how much the golf ball hit by him is located on the entire course.

The partial minimap highlights an area of interest to the user in the entire minimap. For example, when the virtual golf ball simulated by the user is located near the green G, as shown in FIG. 9, the partial minimap may show only an area near the green G. As shown in FIG. Therefore, through the partial minimap, it is possible to grasp detailed information of a specific area, which is difficult to grasp in the entire minimap, such as height and bend of the green, and the user may easily refer to the detail information to facilitate subsequent shots or putting. .

In particular, the partial mini-map according to the present embodiment may serve to provide not only a golf course but also additional information to help a user's golf shot. An example of the additional information may be a distance from a location at which the golf ball hits the target point. For example, as shown in FIG. 9, the distances L1 and L2 from the virtual golf ball VB to the hole cup HC may be displayed when an approach shot is made. In general, the approach shot refers to a case in which the golf ball is hit toward the green (G). In the approach shot, the golf ball (VB) is used in the mini map because the shot must be adjusted according to the distance from the golf ball to the hole cup. Distance from the hole cup (HC) is very important information to the user. Here, the distance L1 from the golf ball VB to the green G and the distance L2 from the green G to the hole cup HC may be displayed separately. You can hit the hole cup (HC) right away when you approach the shot, but in some cases, you can think about putting the golf ball on-green first and then putting it. It is more useful to the user to provide the distance from VB) to the hole cup HC by dividing the area by each area.

As described above, when using the head-mounted device 30b, there is a great advantage in that it simultaneously performs various functions such as obtaining information about the iris and providing information useful for screen golf to the user.

Although specific embodiments of the present invention have been described above, those skilled in the art can understand that the present invention can be implemented in a modified form without departing from the essential characteristics of the present invention. will be. Therefore, the disclosed embodiments should be considered in descriptive sense only and not for purposes of limitation. The scope of the present invention is shown in the claims rather than the foregoing description, and all differences within the scope will be construed as being included in the present invention.
