Description

[0001] MULTI BIOMETRIC TERMINAL AND ACCESS CONTROL SYSTEM HAVING THE SAME [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multi-biometric device and an access system including the same, and more particularly, to a multi-biometric device capable of increasing the recognition rate and speed of biometric data using a plurality of biometric techniques, .

In general, biometrics technology is a technology that utilizes an automated device to measure a person's physical or behavioral characteristics as a person's identification.

Such biometrics can be divided into physical and behavioral feature recognition. Physical feature recognition includes fingerprint recognition, face recognition, iris recognition, vein recognition, retina recognition, hand geometry recognition, and behavioral feature recognition. Speech recognition, gait recognition, and signature recognition.

Recently, in order to increase the accuracy of biometrics, there is a case where a combination of physical feature recognition and behavioral feature recognition is used.

The recognition of physical features during biometrics has been developed for a long time and it has been used as a commercial security technology in various fields such as finance, access control, medical welfare, public, quarantine, and entertainment.

However, when fingerprint recognition, facial recognition, iris recognition, palm vein recognition, etc. belonging to the physical feature recognition are individually applied to the authentication system, the following merits and demerits exist.

First, fingerprint recognition has advantages such as high recognition rate and fast verification speed within 1 second. However, there is a disadvantage in that fingerprint recognition is difficult when the fingerprint is damaged, the finger is injured, or the bandage is wound.

The face recognition has a merit that the user is less sensitive to using the camera and can follow-up by the user's photograph naturally submitted for reading. However, face recognition is disadvantageous in that it is sensitive to angle of illumination or image. In addition, there is a disadvantage that face recognition is difficult when disguising, changing face according to the passage of time, or performing plastic surgery.

Iris recognition is statistically more accurate than DNA analysis, is almost impossible to duplicate, and has the advantage of being able to recognize even wearing glasses. It also has the advantage that it rarely changes throughout its lifetime, except in cases of trauma or very rare disease. However, iris recognition has a disadvantage in that it may have a sense of rejection according to the recognition method, and it is difficult to recognize when the circle lens is worn, and the system construction cost is high.

Intestinal vein recognition can be used for people without fingerprints or fingers, and has the advantage that intravenous veins are less likely to be deformed due to trauma or aging, and replication is almost impossible. However, it is not easy to extract the vein distribution area from the skin background of the back of the hand, and it is disadvantageous in that the hardware configuration is complicated, the miniaturization is difficult, and the construction cost is high.

Due to such advantages and disadvantages, it is not perfect to apply each biometric method to the authentication system. In other words, it is difficult to realize a system with high performance and reliability with only one biometric characteristic.

Therefore, there is a demand for a system that can recognize a plurality of biometric characteristics collectively and authenticate whether or not the user is a pre-registered user. In addition, there is a need to solve a problem that may occur due to the use of such a system, for example, a complicated system and inconvenience to the user.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described with reference to the accompanying drawings. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. In order to clearly illustrate the present invention, parts not related to the description are omitted, and similar parts are denoted by like reference characters throughout the specification.

Throughout the specification, when a part is referred to as being "connected" (connected, connected, coupled) with another part, it is not only the case where it is "directly connected" "Is included. Also, when an element is referred to as "comprising ", it means that it can include other elements, not excluding other elements unless specifically stated otherwise.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The singular expressions include plural expressions unless the context clearly dictates otherwise. In this specification, the terms "comprises" or "having" and the like refer to the presence of stated features, integers, steps, operations, elements, components, or combinations thereof, But do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, or combinations thereof.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be appreciated that the present embodiment describes this multibody biometric device for purposes of passing through a gate (entrance security gate) for ease of illustration, but is not limited thereto and can be applied to any system related to security.

1 is a view showing a state where a user accesses and verifies multiple biometric devices to pass through a gate. Here, the multiple biometric device 100 is a device including a host system capable of recognizing two or more physical features, and details thereof will be described later.

Referring to FIG. 1, a multi-biometric identification apparatus 100 according to the present invention is an apparatus in which a user 1 can be identified when a user of the user 1 approaches in a non-contact state. In addition, even when the user 1 looks at the multiple biometric device 100 while approaching from the outside in a non-contact state, the user 1 can be identified.

After passing through the user recognition and identification process by the multiple biometric device 100, the user 1 is allowed to pass through the gate 700. The gate 700 may be implemented in various forms such as a swinging door and a sliding door, and the structure and the shape thereof are not particularly limited. The guide guide 180 shown in FIG. 1 will be described later.

In the present invention, the " approaching non-contact state " of the user's body means that the user's body, e.g., a finger, palm, or face, is positioned at a distance from the multiple biometric device 100 to the multiple biometric device 100 Approaching position, meaning that the user's body does not contact the multiple biometric device 100. That is, the user experience provided by the multiple biometrics device 100 according to the present invention is such that recognition or identification is performed only when the user's body contacts the multiple biometrics device 100, Or swinging the palm of the hand in the slot is excluded.

In order for the user 1 to pass through the gate 700, the user 1 must authenticate himself / herself through the multiple biometric device 100. To this end, the user 1 provides his or her biometric information to the multiple biometric identification device 100, and the multiple biometric identification device 100 transmits the biometric data acquired from the user 1 to the user 1, The identification data can be compared with the biometric data of the user.

In order for the user 1 to provide his / her biometric information to the multiple biometric device 100, the user 1 may access the multiple biometric device 100, for example his or her finger or palm, ). That is, the biometric data input unit 1100 of the host system 1000 mounted in the multiple biometric device 100 acquires the biometric data of the user 1 while the user 1 performs the above-described actions do. The host system 1000 will be described in more detail with reference to FIG. 2, and only the function thereof will be schematically described here.

The biometric data input unit 1100 of the host system 1000 can acquire biometric data (fingerprint data or palm vein data) through the finger or the palm of the user 1 that is approaching from the outside. In addition, the biometric data input unit 1100 can acquire biometric data (iris data or facial image data) through the iris or face of the user 1 looking at while approaching from the outside.

That is, the biometric data input unit 1100 can acquire two or more of the biometric data of the user (1). For example, the biometric data input unit 1100 can acquire two or more of fingerprint data, vein data (e.g., intestinal vein data), iris data, and face image data.

The time required to acquire the biometric data of the user 1 is usually the fastest face recognition, and the time required to acquire the next iris recognition or fingerprint recognition is intermediate, and vein recognition is the slowest. However, since the time interval for acquiring each biometric data is very short as described above, the user 1 can recognize that each biometric data is recognized almost simultaneously.

Meanwhile, the biometric data identification unit 1300 of the host system 1000 compares the biometric data of the user 1 acquired as described above with the biometric data of the user 1 registered in advance and performs identification. Here, the biometric data identification unit 1300 can identify two or more biometric data obtained at the same time. Of course, there may occur a time difference in identification depending on the type and amount of each biometric data of the user 1 registered in advance. In addition, the biometric data identification unit 1300 may display the biometric data, which is first identified among the biometric data, through the display or the like so that the security manager can confirm the biometric data.

Since the multiple biometric device 100 receives a plurality of biometric data, various access permission conditions can be set. For example, it is possible to permit access based on any one of two or more biometric data for which recognition and identification are performed first. In this case, fast access is allowed.

Alternatively, it is also possible to permit access only when at least two biometric data are recognized and identified. In this case, the security conditions are strengthened, and the probability of access permission or security incidents due to misidentification is lowered.

It is also possible to set access permission conditions by properly combining the above two cases. For example, if the accuracy and stability of data, recognition and identification by a highly secure vein (intestinal vein) or an iris is performed, access based on only one biometric data can be allowed, and data accuracy and stability When recognition and identification by a relatively low facial image are performed, a method of increasing security by requesting recognition / identification by other biometric data, for example, fingerprint or iris, is also possible. In addition, various access permission conditions can be set in consideration of the level of security requirements and the speed of identification.

Next, the configuration of the host system 1000 according to the embodiment of the present invention will be described in detail. 2 is a block diagram of a host system in a multiple biometric device according to an embodiment of the present invention.

2, the host system 1000 of the multiple biometric identification device 100 according to the present invention may include a biometric data input unit 1100, a biometric data registration unit 1200, and a biometric data identification unit 1300 have. In addition, the host system 1000 may further include an ID display unit 1400 and a control unit 1500.

The biometric data input unit 1100 can acquire the biometric data of the user 1. [ The biometric data may be, for example, fingerprint data, iris data, vein data, retina data, face image data, or hand shape data, and the biometric data input unit 1100 may receive two or more of the biometric data.

The biometric data input unit 1100 may have a face recognizing unit 1110, an iris recognizing unit 1120, a fingerprint recognizing unit 1130, and an intestinal vein recognizing unit 1140.

The fingerprint recognition means 1130 may physically be located above the upper surface of the multiple biometric identification device 100. The intestinal vein recognition means 1140 may be spaced apart from the fingerprint recognition means 1130 at predetermined intervals. The iris recognition means 1120 and the face recognition means 1110 may be located in a region between the thumb and the index of the user on one side of the intestinal vein recognition means 1140.

Further, the fingerprint recognition means 1130 may have a plurality of fingerprint recognition cameras capable of acquiring fingerprint data, respectively, and these plurality of fingerprint recognition cameras may be disposed adjacent to each other. The intestinal vein recognition means 1140 may be disposed below the plurality of fingerprint recognition cameras and the iris recognition means 1120 and the face recognition means 1110 may be disposed adjacent to one side of the intestinal vein recognition means 1140 . The details of this can be understood through the matters shown in FIG. 3, and the details will be described later.

The face recognition means 1110 recognizes the face image data, and may be means for recognizing the image data photographed by the face recognition camera 400 shown in FIG. That is, the face recognition unit 1110 may be the face recognition camera 400 itself, or may be a module including the face recognition camera 400. FIG. For example, the face recognition means 1110 may be a module including a face recognition camera 400 and a processor (not shown) for processing the image data photographed by the face recognition camera 400. [

The iris recognition means 1120 recognizes iris data, and may be means for recognizing iris data photographed by the iris recognition camera 500 shown in FIG. That is, the iris recognition unit 1120 may be the iris recognition camera 500 itself, or may be a module including the iris recognition camera 500. For example, the iris recognition means 1120 may be a module including an iris recognition camera 500 and a processor (not shown) for processing the image data photographed by the iris recognition camera 500.

The fingerprint recognition means 1130 recognizes the fingerprint data. For example, the fingerprint recognition means 1130 may be means for recognizing the fingerprint data photographed by the plurality of fingerprint recognition cameras 200 shown in FIG. That is, the fingerprint recognition means 1130 may be a plurality of fingerprint recognition cameras 200 capable of acquiring fingerprint data, respectively. Alternatively, the fingerprint recognition means 1130 may be a module including a plurality of fingerprint recognition cameras 200. For example, the fingerprint recognition means 1130 may be a module including a fingerprint recognition camera 200 and a processor (not shown) for processing the image data photographed by the fingerprint recognition camera 200.

The intestinal vein recognizing means 1140 recognizes the intestine vein data and may be means for recognizing the intestinal vein data photographed by the intestinal vein recognition camera 300 shown in Fig. That is, the intestinal vein recognition means 1140 may be the intestinal vein recognition camera 300 itself, or may be a module including the intestinal vein recognition camera 300. For example, the intestinal vein recognition means 1140 may be a module including a intestinal vein recognition camera 300 and a processor (not shown) for processing the image data photographed by the intestinal vein recognition camera 300.

The biometric data input unit 1100 includes the face recognition unit 1110, the iris recognition unit 1120, the fingerprint recognition unit 1130, and the intestinal vein recognition unit 1140 However, the present invention is not limited thereto, and the biometric data input unit 1100 may have another biometric unit. For example, the biometric data input unit 1100 may have finger vein recognition means, retinal recognition means, or hand shape recognition means.

2, biometric data of the user 1 may be registered in the biometric data registration unit 1200 in advance.

The biometric data identification unit 1300 can compare the biometric data acquired from the biometric data input unit 1100 with the biometric data of the user 1 registered in advance in the biometric data registration unit 1200 to perform identification.

The ID display unit 1400 can display the identification result of the biometric data of the user 1 identified by the biometric data identification unit 1300 by ID. The identification result of the ID display unit 1400 can be confirmed by the security administrator or the user 1. [

The control unit 1500 is connected to the biometric data input unit 1100, the biometric data registration unit 1200, the biometric data identification unit 1300, and the ID display unit 1400 and instructs them to perform the respective operations .

Hereinafter, the registration, recognition, and identification of biometric data using the multi-biometric device 100 according to the present invention will be described.

First, a user or an administrator must register the biometric data of the user 1 in the multiple biometric device 100. The biometric data registration of the user 1 is basically an act of extracting and storing the characteristic of the user 1. All the biometric data of the user 1 thus acquired can be stored in the biometric data registration unit 1200. [ All biometric data of the user 1 registered in the biometric data registration unit 1200 can be backed up in the biometric data storage database 2000 for the purpose of data storage. The host system 1000 of the multi-biometric device 100 and the biometric data storage database 2000 may be connected by wire or wirelessly. Details of the biometric data storage database 2000 will be described later.

Next, in order for the user 1 to pass through the gate, the user 1 must prove himself / herself. To this end, the user 1 inputs his / her own biometric data through the biometric data input unit 1100. [

When the biometric data input unit 1100 receives the biometric data of the user 1, the biometric data identification unit 1300 identifies the biometric data of the input user 1 and the user 1 registered in the biometric data registration unit 1200 ) To compare the biometric data of the user with the biometric data of the user. At this time, the biometric data identification unit 1300 may perform verification to confirm the identity of the user by one-to-one matching or perform identification to find the user 1 among many people by one-to-N matching It is possible. In other words, strictly speaking, authentication and identification are separate and selectively used depending on the application domain. However, in the present invention, the term " authentication " or " identification " refers to a process of verifying or finding the identity of a person using biometric data. However, in the present embodiment, the biometric data identification unit 1300 performs identification by one-to-N matching that matches one user and a plurality of users.

The data stored in the biometric data registration unit 1200 is data in which all of the plurality of biometric data of the user 1 is registered and the biometric data input unit 1100 inputs a predetermined number or more of the plurality of biometric data of the user 1 Input can be received.

More specifically, when the biometric data of the user 1 is input from the biometric data input unit 1100, the biometric data identification unit 1300 identifies the biometric data and the biometric data of the plurality of users registered in the biometric data registration unit 1200 Identify the data. At this time, the biometric data of the user 1 input to the biometric data input unit 1100 may be a plurality of biometric data. That is, the biometric data of the user 1 may be two or more of iris data, face image data, fingerprint data, or intestinal vein data. The biometric data identification unit 1300 identifies each of the plurality of biometric data registered in the biometric data registration unit 1200 according to the number of the biometric data of the user 1 input to the biometric data input unit 1100 .

For example, when the biometric data of the user 1 input to the biometric data input unit 1100 is iris data or fingerprint data, the biometric data identification unit 1300 identifies a plurality of users registered in the biometric data registration unit 1200 The iris data or the fingerprint data of the fingerprint data is used to perform the identification. Of course, when the biometric data input unit 1100 is set to one or more than one biometric data of the user 1 to be input, the biometric data identification unit 1300 may be configured to match the number of biometric data of the input user 1 It is possible to perform identification with respect to each of the plurality of biometric data registered in the biometric data register 1200.

The result of the identification can be displayed by the ID display unit 1400 of the host system 1000. The ID display unit 1400 may sequentially display the biometric data of the user 1 from the identification result of the completed biometric data among the plurality of biometric data.

For example, it is assumed that the biometric data identification unit 1300 performs identification of iris data, face image data, and fingerprint data. At this time, when the identification of the biometric data is performed in the order of the face image data, the fingerprint data, and the iris data, the ID display unit 1400 can display the identification result in the order of the face image data, the fingerprint data and the iris data.

On the other hand, even if only one or two of the above three identification results (iris, face, and fingerprint) are unsuccessful and succeed, only the identification of the user 1 can be indicated depending on the setting. In addition, if all three identification results are not successful, or if some of the three identification results are not successfully identified, depending on the setting, it may indicate that the identification of the user 1 has failed. As described above, it is possible to set various entrance conditions as described above.

Referring again to FIG. 2, the host system 1000 according to the present embodiment may further include a biometric data storage database 2000 for backing up data registered in the biometric data registration unit 1200. When a problem such as an artificial mistake, a hardware problem, a software problem, a theft, a computer virus, a cyber terrorism, a disaster, or the like occurs, the biometric information of the user 1 registered in the biometric data registration unit 1200 may be lost . Therefore, the data of the biometric data registration unit 1200 can be set to be regularly backed up in the biometric data storage database 2000. [

As described above, the biometric data storage database 2000 that backs up the data of the biometric data registration unit 1200 can be used as a tamper protection function. That is, if the host system 1000 is separated from the multiple biometric device 100, all the data registered in the biometric data registration unit 1200 can be deleted. Conversely, when the host system 1000 is reconnected to the controller, the data backed up in the biometric data storage database 2000 can be restored to the biometric data registration unit 1200. [ This is equally applicable when the host system 1000 is detached from or reconnected to the controller of the gate 700. [

Accordingly, it is possible to prevent loss of biometric data, which is personal information, even if the multiple biometric device 100 including the host system 1000 according to the present invention is lost due to theft or the like. That is, when the host system 1000 existing in the multiple biometric device 100 according to the present invention is separated from the multiple biometric device 100 or separated from the controller of the gate 700, the biometric data registration unit 1200 Is deleted, it is possible to prevent the problem that the biometric data of the user is leaked in advance. When the host system 1000 of the separated multiple biometric device 100 is again connected to the controller of the gate 700, all of the data backed up in the biometric data storage database 2000 is transferred to the biometric data registration unit 1200 It is not necessary to re-input the biometric data even when the multiple biometric device 100 is detached from the gate 700 and reconnected again for the purpose of error correction, repair, management, or the like.

Next, a specific implementation example of the multiple biometric device according to the present invention will be described with reference to the drawings. FIG. 3 is an exploded perspective view of a multi-biometric device according to an embodiment of the present invention, and FIG. 4 is an assembled perspective view of a multi-biometric device according to an embodiment of the present invention.

The figure shows a multi-biometric device 100 having a hollow interior and a spherical housing. However, it is to be appreciated that the multi-biometric device 100 according to the present invention is not limited to a spherical housing but may have a housing of various shapes.

The multi-biometric device 100 or the host system 1000 according to the present invention may be provided to be housed in one module or a housing. Here, " housed in one module or housing " means that the means for recognizing a plurality of biometric data are housed in separate modules or housings, so that recognition of biometric data is performed in a separate device, It means that setting of the recognition means or position adjustment is not performed individually. That is, means for recognizing a plurality of biometric data is provided in one device and is modularized. Here, the module or housing may be integrally provided, or alternatively, a plurality of enclosures (or members) may be coupled.

When the expressions are different, the fingerprint recognition means, the intestinal vein recognition means, the iris recognition means, and the face recognition means can be accommodated in one housing and modularized, and the technical meaning thereof is the same as above.

Referring to FIG. 3, the multi-biometric device 100 according to the present invention may be constructed by combining six envelopes. That is, the envelope of the multiple biometric device 100 comprises a front member 110, a back member 120, two side members 130 located on both sides, an upper member 140, and a lower member 150 . The six members may be combined to form a spherical housing having a hollow interior.

The two side members 130 can be detachably attached to the rear member 120. The system administrator can mount the host system 1000 or the biometric module inside the multiple biometric device 100 by opening the side member 130 or facilitate maintenance and repair activities.

The upper member 140 may be attached to an area inclined at a predetermined angle in the vertical direction in consideration of the convenience (accessibility) of the user. Thus, when the finger or palm of the user 1 approaches the multiple biometric device 100, the user 1 can maintain a more comfortable posture. Further, the upper member 140 may be formed of a half mirror. The structure of the upper member 140 will be described in detail later.

The lower member 150 may have a first through hole 151 at a central portion thereof. The first through hole 151 may be provided to connect the controller of the multi-biometric device 100 and the gate 700. [ The front member 110 and the rear member 120 may have a generally spherical housing shape. The front member 110, the rear member 120, the both side members 130 and the upper member 140 except the lower member 150 can be fixed by the ring-shaped fixing member 160.

In addition, a plurality of second through holes 141 and 142 may be formed on one side of the upper member 140 positioned in a region inclined at a predetermined angle in the vertical direction. The fingerprint recognition camera 200 may be inserted into the plurality of second through holes 141 and 142, respectively. The plurality of second through holes 141 and 142 may include a 2-1th through hole 141 and a 2-2th through hole 142. The first fingerprint recognition camera 210 inserted in the second-1 through-hole 141 photographs a predetermined number of fingerprints of the remaining fingers except for the thumb, The second fingerprint recognition camera 220 can photograph a fingerprint of the finger other than the thumb, which the first fingerprint recognition camera 210 has not captured.

For example, when the first fingerprint camera 210 photographs the second fingerprint, the third fingerprint, and the fourth fingerprint of the user 1, the second fingerprint recognition camera 220 detects the user 1, The fifth fingerprint of the fifth fingerprint can be photographed. Alternatively, the first fingerprint recognition camera 210 may capture only the second fingerprint of the user 1, and the second fingerprint recognition camera 220 may capture the fingerprint of the third, fourth, As shown in FIG. Alternatively, the first fingerprint recognition camera 210 and the second fingerprint recognition camera 220 may photograph two fingerprints of the user 1, respectively. That is, the fingerprint recognition camera 200 simultaneously captures the remaining four fingerprint fingerprints except the thumb of the user 1. Here, the photographing of the fingerprint of the user 1 by the fingerprint recognition camera 200 can be performed in a touchless manner in which the finger of the user 1 is not in contact with the multiple biometric identification device 100. Similarly, the imaging of the intestinal vein data of the user 1 by the intestinal vein recognition camera 300 can also be performed in a noncontact manner in which the palm of the user 1 is not in contact with the multiple biometric device 100.

The intestinal vein recognition camera 300 can be positioned at a predetermined interval below the fingerprint recognition camera 200 based on a direction in which the user views the upper member 140 from the outside. The user 1 approaches his or her multibody recognition device 100 in order to input his or her biometric data to the biometric data input part 1100 of the multiple biometric device 100, The palm of the user 1 can be automatically aligned at a position facing the intestinal vein recognition camera 300. The finger vein recognition camera 300 of FIG. The iris recognition camera 500 and the face recognition camera 400 may be positioned at the upper and lower sides of one side of the intestinal vein recognition camera 300, respectively. The iris recognition camera 500 or the face recognition camera 400 can photograph the iris and the face of the user 1 between the thumb and forefinger of the user 1, respectively. Although the iris recognition camera 500 is located above the face recognition camera 400 in the present specification, the positions of the face recognition camera 400 and the iris recognition camera 500 may be reversed. In place of the iris recognition camera 500 or the face recognition camera 400, another biometric camera (for example, a retina recognition camera) may be located.

The iris recognition camera 500 and the face recognition camera 400 may be driven by a pan-tilt driver 600. That is, the iris recognition camera 500 and the face recognition camera 400 can photograph the iris or the face of the user 1 while moving or rotating in the horizontal direction or the vertical direction by the pan tilt driver 600, respectively. By this physical movement, the pan tilt driver 600 can perform a mechanical (non-optical) zoom-in and zoom-out function whereby the iris recognition camera 500 or the face recognition camera 400 can perform You can shoot iris size or face size while adjusting or focusing. Of course, the iris recognition camera 500 or the face recognition camera 400 may have optical zoom-in and zoom-out functions, and thus may be implemented simultaneously or separately with the non-optical zoom in / zoom out function by the pan tilt driver Do.

The user 1 does not need to approach the iris recognition camera 500 or the face recognition camera 400 by approaching the iris or the face of the user 1 to each other. That is, the iris recognition camera 500 or the face recognition camera 400 can always photograph iris or face of the user 1 regardless of the distance by the pan tilt driver 600 at a constant size. The iris recognition camera 500 and the face recognition camera 400 may be driven by the same pan tilt driver 600 while being positioned adjacent to each other. Although not shown, it is also possible that the iris recognition camera 500 and the face recognition camera 400 are individually driven by separate pan tilt drivers.

A ring-shaped light source 170 may be mounted between the upper member 140 and the fixing member 160. This light source 170 may have a functional effect of guiding the user ' s finger or palm with decorative or aesthetic effects.

Fig.

In some embodiments of the present invention, all or a portion of the housing may be a multi-layered structure including a color optical resin layer, a half-mirror coating layer, and an anti- Sectional structure.

Referring to FIG. 3, the housing may have a structure in which, for example, six members are coupled to form a hollow interior, and a part of the housing, for example, the upper member 140 may have the multi-layer structure described above. 5, the upper member 140 includes a color optical resin layer 1401 partially blocking visible light, an anti-mirror coating layer 1402 provided on the upper surface of the color optical resin layer 1401, And an anti-reflection coating layer 1403 provided on the lower surface of the resin layer 1401. Here, the upper surface means the side in contact with the user.

The anti-mirror coating layer 1402 has a function of reflecting a part of incident visible light and can be formed by a dielectric multilayer thin film or a metal film coating.

In the case of the dielectric multilayer thin film, the dielectric constant and low dielectric constant layers may be laminated and formed, and may include dielectric oxides such as SiO ₂ , SiO ₂ , ZrO ₂ , and TiO ₂ . In the case of a metal film, for example, a Cr thin film may be deposited, and a dielectric thin film may be added to the upper and lower surfaces of the Cr thin film to serve as a protective layer of the Cr thin film.

The semi-mirror coating layer 1402 can be formed by vacuum deposition, sputtering, evaporation coating, spin coating or the like, but is not particularly limited to such a manufacturing method.

The amount of visible light incident on the inside of the upper member 140 from the outside of the upper member 140 through the upper member 140 to the inside of the upper member 140 and the amount of visible light incident from the inside of the upper member 140 by the upper member 140 The ratio b / a of the reflection amount b of the visible light incident on the inside of the upper member 140 may be 30% or less. When the ratio b / a between the incident amount and the reflection amount exceeds 30%, the internal member (camera and the like) is also picked up when the camera built in the housing picks up a user (such as a face or an iris) The biometric information is not recognized or the recognition rate is lowered.

6, assuming that the color optical resin layer 1401 of the upper member 140 has a visible light attenuation of 50% and the semi-mirror coating layer 1402 has a visible light reflectance of 20%, the upper member 140 The incident amount a of the visible light incident from the outside of the upper member 140 is 30% and the reflection amount b of the visible light reflected by the upper member 140 from the inside of the upper member 140 is 3.6% (30% * 50% * (20% + 4%)). In this case, the ratio of the incident amount to the reflection amount (b / a) is 12%.

Meanwhile, the upper member 140 may further include an additional coating layer in addition to the above-described coating layer. 7, when the anti-reflection coating layer located in the color optical resin layer 1401 is referred to as a first anti-reflective coating layer 1403, the anti-reflection coating layer 1403 is formed between the color optical resin layer 1401 and the anti- SECOND ARTICLE-A reflective coating layer 1404 may be further provided. The second reflection-reflective coating layer 1404 can further reduce the internal reflection amount b of the visible light.

In addition, a cured coating layer 1405 or a fingerprint-preventing coating layer 1406 may be further provided on the upper surface of the anti-mirror coating layer 1402.
