The storage medium 205 determines whether authentication is successful or not by Save the template of biological information of a user who previously harvested registered, the authentication processing unit 204 compares the user template and the detection pattern matching. It is possible to enhance the security of the wearable device 100 by performing user authentication using biometric authentication. Biometric information used for biometric authentication, a palm print, a fingerprint, vein, iris, retina, face, hand geometry, voice print, EEG, may be detected biometric features, such as the pulse wave. These biometric information is performed is acquired by the biological information detection section 291.

The biological information detecting unit 291 may be, for example, an imaging unit 109 shown in dedicated imaging portion or Figure 1C for detecting separately the iris or retina provided an imaging unit 202, use a sensor of capacitive type may be a fingerprint detector which had, it may be a detector for detecting the brain wave and pulse wave optically or electrically. However, not limited to only the biological information detecting unit 291 is provided, living body information detection unit 291 may be shared with all other components or parts, imaging as shown in FIG. 1B part 106 may be switchable.

For example the imaging unit 202 for capturing a portion of a user's field of view, a biological information palm print, a fingerprint, a vein, by performing the detection of such a palm shape, the biological information detecting unit 291 and the imaging unit 202 is shared, palm print, fingerprint, vein, it is possible to reduce the size and weight of the wearable device 100 there is no need to provide a detection only of the biological information detecting unit 291 such as a palm shape. Further, by performing the detection of the voice print by voice input and output unit 210, the biological information detecting unit 291 and the audio output unit 210 is shared, there is no need to provide a detection only of the biological information detecting unit 291 of the voiceprint.

To suppress the authentication accuracy by the position displacement of the detection object during authentication from deteriorating, wearable device 100 in the video display unit 203 generates a guide for position guiding the sight of the user as auxiliary information in the auxiliary information generation unit 290 it may be displayed. As auxiliary information in the detection of the iris and the retina, by the position guide to specify the direction of the line of sight is displayed, it may be suppressed movement of the eyeball, and in the dark display of the image display unit 203 to open the pupil it may be. Furthermore, as auxiliary information in the detection of a fingerprint, the start timing of the scan may be displayed. Furthermore, as auxiliary information in the detection of voiceprint, display and which instructs the start of sounding, to be sounded phrase is displayed, the timing of the phrase reading may be displayed by changing the color of the text in turn. Wearable device 100 by providing supplementary information in accordance with the authentication method to the user, it is possible to improve the authentication accuracy.

The imaging unit 202 for capturing a field of view of the user in the following, palm prints, fingerprints, performs detection of the biological information of the vein, and bio-information detecting unit 291 and the imaging unit 202 is shared, a dedicated bio-information detection unit 291 need not, be described in further detail configuration example of a wearable device 100 reducing the size and weight.

Figure 3 is a diagram showing an example of the configuration of a wearable device 100c when the biological information detecting unit 291 and the imaging unit 202 has shared. Wearable device 100c shown in FIG. 3 has no auxiliary information generation unit 290 and the biological information detector 291 shown in FIG. 2, it has a position guide image generating unit 213 and the position guide 212, and the other 2 having the configuration described with reference.

User by holding the palm, for example, in the imaging range 105 of the imaging unit 202, the wearable device 100c detects the palm print of a pattern as biometric information. The authentication processing unit 204 determines whether authentication is successful or not by matching by comparing the detected pattern with the user templates stored in the storage medium 205. For detected amount of ambient light is insufficient shooting is difficult, especially equipped with a lighting mechanism not shown in the wearable device 100c, may be increased amount with respect to the inspection object by the illumination mechanism.

Although the imaging unit 202 in place of the biological information detecting unit 291 is possible to photograph, there is the following problem when determining the authentication. That is, in order to change the pattern taken by positional deviation or inclination of the palm when the pattern detection by capturing the palm print, hard to match the pattern of the registered template, there is a problem that the authentication accuracy is degraded significantly. For the more common biometric authentication device products to suppress the displacement of the detection target of the biological information, to be placed at the same position repeatedly detected, with a table for positioning the test object. Then, the pattern detection The table that is positioned by placing the test object on the positioning base.

However, the wearable device 100c having a positioning base is difficult to reduce the size, attachment of the wearable device is lowered. In addition, the design constraints of the appearance of the wearable device 100c. Accordingly, for positioning, the position guiding unit 212, to be placed in the correct position at the time of authentication detected without using the positioning base.

Figure 4 is a diagram showing an example of a position guide. Position guiding unit 212 in this example displays the position guide 110 in a partial area 103 in the user's field of view by using the video display unit 203. Image information of the position guide 110 has been generated by the position guide image generating unit 213, a palm contour during palm print pattern registration. Video display unit 203 displays a virtual image of the palm of the contour position with respect to the imaging unit 202 at the time of registration in the user's field of view, i.e., the position guide 110 augmented reality the detection object 111 of the real image (Augmented Reality: AR) appear as and, the auxiliary information indicating where to place the palm. User when the saw position guide 110 displayed as AR, by moving (palm in the example of FIG. 4) detected 111 to overlap it, the detection object 111 registering the time substantially equal to the position and inclination it can be arranged.

Although palm FIG 4 has been described as an example of a detection target of the living body information detection target is not intended to feel more alert limited to palm, position guide is also not limited to the palm of the contour. FIGS. 5A ~ 5C are diagrams showing an example of another location assistance. Example of FIG. 5A is a detection target or the like or fingerprints palm prints, the position guide 110a is a mark of the cross indicates the center portion and the position reference of the predetermined finger of the palm by crisscross marks. Example of FIG. 5B is a detected fingerprint, the position guide 110b is a contour of a finger, showing the position overlaying the detected finger. Further, as a detection target palm print, etc., the position guide 110b is a contour of a plurality of fingers, it indicates the position overlaying the plurality of fingers to be detected, may identify the palm position. Example of FIG. 5C is a detection target vein or the like of a palm print or a palm, the position guide 110c is a pattern such as a typical palm print and vein that can be easily visually not outline shows the position overlaying the palm detected. It is other than described above, in accordance with the detection target of a variety of biological information, as long as it is informed position to be arranged to be detected to the user, the display format of the position guide is not limited. The following describes the position guide 110a, 110b, 110c, etc. may be included typically position guide 110.

Further, when the user of the detection target is in place at the time of position guiding, by displaying the wearable device 100 is located judgment result in real time, it may inform the user that the detected target is put in the correct position . The position determination result may be displayed in characters, by such changing the display color of the position guide 110, that is placed in the correct position of the detection object may be recognized to intuitively user. The video display unit 203 by displaying the authentication result to the AR, the user can confirm in real time without eye movement the authentication result, the display of the wearable device 100c can be effectively utilized.

Further, only when the position of the position guide 110 and the detection object 111 is matched by the pattern matching between the template using the captured image obtained from the imaging unit 202, necessary to the determination processing for unnecessary authentication is eliminated, it is possible to suppress the power consumption in limited wearable device 100 of power supply capacity to operate by a battery. In addition to such suppression of power consumption, acceleration sensors, proximity sensors, with a configuration for starting the authentication process a predetermined input signal from the sensor input and output unit 206, such as a touch sensor as a trigger, only when necessary to You can initiate the authentication process, the other may be the power consumption was suppressed in the limited wearable device 100c of the power supply capacity to operate by a battery by a standby state, to realize the long drive.

6 is a diagram showing an example of a flowchart of a biometric authentication in the wearable device 100. Wearable device 100 starts the process at step 301. Wearable device 100 determines whether a trigger signal for authentication processing start from the sensor input unit 206 at step 302. Wearable device 100 if it detects a trigger signal in step 302, starts the authentication process at step 380. Wearable device 100 displays the auxiliary information in step 381.

Wearable device 100 determines whether the authentication by comparing and collating the biometric information pattern detected with the template data registered in the storage medium 205 in step 307. If authentication succeeds as a result of the matching, the wearable device 100 performs authentication result display informing that it has succeeded in step 308, the display of detailed information. If the authentication fails in step 307, the wearable device 100 to display results of notifying failed in step 309 to the user, and ends the display of the related information.

Particularly detecting biological information using the imaging unit 202, an example of a flowchart of a biometric authentication when displaying the position guide 110 as auxiliary information shown in FIG. Wearable device 100c starts processing at step 301. Wearable device 100c determines whether the trigger signal of the authentication processing start from the sensor input unit 206 at step 302. Wearable device 100c when detecting the trigger signal in step 302, the imaging unit 202 to initiate an authentication process in step 303 to start the photographing. Wearable device 100c displays the position guide 110 in a partial area 103 in the user's field of view by the image display unit 203 in step 304 as AR. Display with these imaging continues at least steps 304-307. Wearable device 100c is determined on the basis of whether the user so as to overlap the position guide 110 at step 305 could be arranged to detect object 111 in the captured image of the imaging unit 202. If the position could be correctly positioned, the wearable device 100c carries out a display for informing the position determination result to the user in step 306. Wearable device 100c determines whether the authentication by comparing and collating the biometric information pattern detected by the template data and the imaging unit 202 registered in the storage medium 205 in step 307. If authentication succeeds as a result of the matching, the wearable device 100c performs authentication result display informing that it has succeeded in step 308, the display of detailed information. If the authentication fails in step 307, the wearable device 100c performs display result notifying failed in step 309 to the user, and ends the display of the related information.

As described above, a wearable device 100 having an image display unit 203 for displaying predetermined information on the viewing direction of the user in the external world visible state, a storage medium 205 for storing user information, the user performs an imaging unit 202 for capturing the direction of view, the detection of biological information of a user from a test object placed in a region where the inside overlap the imaging range of the display range and the imaging unit 202 of the image display unit 203 of the detected biometric by comprising the authentication processing section 204 which collates the information stored in the storage medium 205 templates for user authentication, in wearable information display terminal or the like is small and light, with a simple configuration It can be accurately authenticate the user.

It will now be described in detail cooperation with external information processing apparatus using the communication unit 208. Figure 8 is a diagram showing an example of a communication connection cooperation with wearable device 100 and the external information processing apparatus (external apparatus). Wearable device 100 by the communication unit 208 via the Internet 150, PC 151, smartphones 152, the server 153 communicates with an external device such as another wearable device 154, video display unit 203 of the wearable device 100 the information in the external device it can be displayed within the user's view by. Here, instead of the internet 0.99, Bluetooth (registered trademark), Wifi (registered trademark), UHF, the near / far wireless communication VHF etc. may perform communication.

In order to enhance the confidentiality of the time of viewing / editing information in the external device from the wearable device 100 to establish a communication connection with the external device after user authentication. Therefore, rather than using only the availability of wearable device 100 to the user authentication in the authentication processing unit 204 is used in user authentication when establishing a communication connection with the external device. Thus, it is possible to improve the confidentiality of the convenience and information of the user when to link external device wearable device 100.

The authentication in the communication connection cooperation shown in FIG. 8 is classified to the host authentication and self authentication scheme according to whether the position is that which device on which to perform the determination of the authentication. The host authentication method is in position determination authentication on the server 153 via the Internet 150, the wearable device 100 connected by transmission to the server 153 side of the picture by the imaging unit 202, a method of performing authentication. On the other hand, there is in the housing of the self-authentication method same wearable device 100 and the imaging unit 202 the position of the determination of authentication is a method in which also the server 153 side authentication wearable device 100. The host authentication method may be a communication of the picture, but require a network system using a dedicated server, the system becomes complicated. On the other hand, the self-authentication method does not require a network system using a dedicated server can be a small-scale system.

It will be described in detail the self-certification system in the following. Figure 9 is a diagram showing an example of a configuration relating to the authentication of a wearable device 100d and the external device 250. Wearable device 100d has a configuration as the signature portion 214 of the wearable device 100c described with reference to FIG. Further, the external device 250 is PC151, smartphones 152 shown in FIG. 8, a server 153, other wearable device 154 and the like. Wearable device 100d performs against the registration data the biological information detected by the imaging section 202 by the authentication processing unit 204 the authentication in the self authentication scheme. At the same time the authentication is made possible detailed functions and information display of the wearable device 100d If successful, the wearable device 100d communicates with an external device 250 via the Internet 150, the authentication request from the authentication requesting unit 251 of the external device 250 upon receiving, and notifies the user authentication result to the external device 250. Thus, the external device 250 can check the execution result of biometric authentication in remote areas of the wearable device 100d.

In addition to authentication, the communication between the wearable device 100d and the external device 250, for example, by use of the public key encryption can be a system that ensures confidentiality. Based on the verification result of the authentication processing unit 204, the authentication information of the identification information of the verification result and the authentication request from the user information and the server, the signature unit 214 performs signature by (secret) encryption keys, wearable device 100d transmits the authentication information has been performed signed to the external device 250. In contrast, the external device 250 is verified using the validity of the user (public) key by the authentication section 252. When you are a user authentication confirmation on the external device 250 side to allow the connection between the wearable device 100d, display of the internal information can be wearable device 100d side.

Figure 10 is a diagram showing an example of a flowchart of an authentication connection with the wearable device 100d and the external device 250. Biometric authentication processing in step 310 in FIG. 10 is a step 302-307 as described with reference to FIG. Wearable device 100d sends a connection request to the external device 250 in step 311. Wearable device 100d receives the authentication request from the external device 250 in step 312. Wearable device 100d is verification result based on the collation result in step 313, a signature by (secret) encryption key to the authentication information, such as identification information of the user information, the authentication request from the server. Wearable device 100d transmits the authentication information was signed in step 314 to an external device 250. External device 250 of whether those to the authentication request the authentication information received in step 315 was issued earlier, and verified using the validity of the user (public) key, and determines the validity of the target user. External device 250 allows display the internal details of the external device 250 as long obtained validity to the determination result in step 316. If legitimacy can not be obtained external device 250 terminates the display of the related information in step 317.

It will now be described registration procedure of the template used for matching of the biometric authentication. Figure 11 is a diagram showing an example of a flowchart of template registration procedure. Wearable device 100 registers the biometric information using the sensing unit 207 and the audio processor 211 in step 330 is indicated. Wearable device 100 by being a predetermined operation and pronunciation specifically by the touch sensor 107 or audio for example may be employed to instructions. Wearable device 100 when starting the registration process in step 331, displayed to the user's view of the position target to place the detection target as AR on the video display unit 203. Wearable device 100 detects the biological information by the imaging unit 202 at step 332.

Wearable device 100 registers the pattern of biometric information detected by the step 333 in the recording medium 205. Wearable device 100 can increase the authentication accuracy by registering the storage medium 205 and generates a position guide data by position guide image generating unit 213 in step 334, displayed when the user authentication as position guide 110 as described above. PC151 and smartphones 152, server 153, when used in connection cooperation with an external device such as another wearable device 154, the wearable device 100 to determine self-authentication or host authentication at step 335, at step 336, if the self-authentication to register in association with the template registered with the user account on the server side. Further, if the host authentication, wearable device 100 sends the pattern data in step 337 to an external device for determining the host authentication, it registers the biometric information as a user template.

It will be described in detail the generation of the position guide data at the position guidance image generation unit 213. For example in the case of using the palm of the contour extracting a contour from the palm of the captured image acquired by the imaging unit 202. If the installation position and the user's eye position of the imaging unit 202 is shifted, so that the difference is generated in the field and the user's field of view of the imaging unit 202. Therefore, when displayed on the user's field of view by the image display unit 203 as a contour image acquired by the imaging unit 202, and can not be guided to the deviation occur would correct position from the position of the correct contour. In addition, when displaying the contour image display unit 203, should be displayed in adjusting the magnitude of the detected scale.

And specifications such as the respective power imaging unit 202 and the video display unit 203, and the positional relationship between the imaging unit 202 and the video display unit 203, the approximate position of the eyes of the image display unit 203 and the user is determined during the design of the wearable device 100 Therefore, previously determined coefficients of correction based on them. Then, a geometrically image correction differences of differences and the display magnification of the view by the position guide image generating unit 213, by registering in the storage medium 205, it is accurately positioned guided by the time of authentication, improve authentication accuracy be able to.

When not using the position guide image generating unit 213 displays a position guide mark in the same fixed time of authentication and time of registration, the user relative position guide mark of the displayed fixed by positioning the detection target , it is possible to suppress positional deviation at the time of authentication during registration, and it is not necessary to provide a position guide image generating unit 213, it is possible to simplify the processing at the time of registration.

Next, a procedure of changing the template used for matching of the biometric authentication. Figure 12 is a diagram showing an example of a flowchart of template change procedure.
