Description

  The present invention relates to a biometric authentication apparatus that is connected to various information processing apparatuses and authenticates the right to use the information processing apparatus, and an information processing apparatus including the biometric authentication apparatus.

  In recent years, importance has been placed on problems related to information leakage, and authentication apparatuses for authority to use information processing apparatuses storing important data have been in the spotlight. Conventionally, when an information processing apparatus is used, a password is generally set and the information processing apparatus can be used by authenticating the password. However, in recent years, fingerprint authentication, finger vein authentication, etc. Authentication devices using biometric information have become mainstream. Furthermore, these biometric authentication devices have been reduced in size, and portable biometric authentication devices that are externally connected by USB connection to an information processing device have also been proposed.

  For example, in a conventional finger vein authentication device connected to an information processing device through a USB connection, a protruding guide for placing a finger is provided on the upper surface of a flat main body, and by placing the finger on this guide, The reflected light is photographed with an internal camera, the signal is transmitted to the information processing device, and authentication is performed based on whether the analysis information of the photographed image matches the analysis information registered in advance. Is going.

  On the other hand, in the information processing apparatus, there is a screen saver technique for displaying other information on a display screen when a predetermined time elapses during driving. This screen saver was originally developed to prevent burn-in of display devices. However, in recent years, when releasing this screen saver, a password is set to prevent information leakage while the user is leaving the office. ing.

  In order to cancel the screen saver, a biometric authentication device can be used in place of the password, or the password and the biometric authentication can be used together to make it impossible for another person who is away from the desk to use the screen saver.

  However, the screen saver counts the time when it is not operated, and starts when this time elapses. For this reason, there is a problem that another person can use this information processing apparatus until a predetermined time has elapsed after the user leaves the office.

  On the other hand, in the conventional biometric authentication device, since the photographing surface on which the finger is placed is exposed, there is a problem that dust or the like adheres to the photographing surface or is easily damaged when being carried. In particular, in a biometric authentication apparatus that inserts a finger or hand between a light source and a light receiving unit and acquires biometric information such as the finger or hand, the apparatus becomes large and there is a problem in portability.

  Accordingly, an object of the present invention is to provide a biometric authentication apparatus that changes the form between use and storage and controls the operation of the screen saver in accordance with the change in form.

  In order to achieve the above object, the present invention provides a first main body having a light source part, a second main body having a photographing part, and the light source part and the photographing part in a first state at a predetermined interval. The first body is movably connected to the second body so as to be concealed between the first body and the second body in the second state. And a drive signal generator for outputting a screen saver drive signal in the second state.

It is a prepared point. The information processing apparatus 1 </ b> A can set a screen saver that displays preset screen information on a display screen when a predetermined time has elapsed. Further, by providing the drive signal generation unit, the screen saver can be driven as the form changes from the use state to the storage state, so that the screen saver is driven when leaving the seat or at any time. Can be made.

  Another major feature of this authentication system is that the addresses of the company server 51 and the home server 52 set in advance during biometric authentication are selected, and the selected server is selected based on this selection. Easy access to.

  Hereinafter, the information processing apparatus to which the biometric authentication apparatus according to this embodiment is connected will be described in more detail with reference to FIGS.

  In FIG. 2, in this embodiment, the information processing apparatus 1A and the biometric authentication apparatus 100 can be connected to each other through a USB terminal so that the power and information of both apparatuses can be shared. The information processing apparatus 1A includes a storage unit 6 that stores various types of information, a display unit 3 that displays various types of information, a communication unit 7 for connecting to a network 50, and a keyboard 4 and a mouse 5. And an input unit 8 and a control unit 9 that comprehensively controls the information processing apparatus 1A.

  The biometric authentication device 100 includes a light source unit 111, a photographing unit 121 (camera), a switch 160 (driving signal generating unit), an interference filter 122, an image processing unit 123, and the like. The finger vein information image signal can be acquired via the interference filter 122 by inserting a finger between the two. This finger vein information acquires a finger blood vessel pattern as graphic information. If palm vein information or other biological information can be used instead of finger vein information, they may be used.

  The image signal of the photographing unit 121 is converted into digital information by the image processing unit 123 and stored in the storage unit 6 via the input / output interface 124 of the information processing apparatus 1A. Further, the switch 160 is similarly connected via the input / output interface 124, and the on / off state is stored in the storage unit 6, or an interrupt signal is sent to the control unit 9 at the same time when the switch 160 is turned off. appear.

  In the present embodiment, the biometric information reading unit constituting the biometric authentication apparatus 100 reads the finger vein and uses it for authentication. Therefore, the authentication information is compared with the case where the palm vein is read and used for authentication. The capacity of the authentication device is small, the authentication speed is fast, and the authentication device is small and easy to use.

  The control unit 9 activates and executes a software program for performing authentication when the information processing apparatus 1A is activated, when the screen saver is released, and when authentication is required in various programs. Then, based on the processing result of the program, the result is displayed on the display unit, or predetermined processing based on the authentication result is executed.

  In this embodiment, when the control unit 9 receives an interrupt signal from the biometric authentication device 100, the screen saver program is executed. As a result, the user can activate the screen saver at any desired time by simply pushing the first main body 110.

Next, with reference to FIG. 3 and FIG. 4, the external structure of the biometric authentication apparatus 100 according to this embodiment will be described.
In this embodiment, the entire biometric authentication device 100 is rounded in the front and rear directions, and has an external shape based on a tapering roundness directed upward. In order to realize this appearance, the planar shape of the second main body 120 is an elliptical shape having a depth in the front-rear direction in which the front and rear surfaces are formed by arcs, and the peripheral side surface is formed by an inclined surface opened downward. Yes. On the other hand, the first main body 110 is formed in a thin plate shape having a planar shape that is slightly smaller than the second main body 120, and includes a pair of support columns 151 extending downward on both sides of the lower surface of the first main body 110. In the center of the bottom surface of the first main body 110, a light source unit 111 arranged linearly in the front-rear direction is disposed. The light source unit 111 is composed of a plurality of LED light sources. Meanwhile, a guide 125 for setting a finger at a predetermined position protrudes from the upper surface of the second main body 120. As shown in FIGS. 3A and 3B, the center of the guide 125 is open, and the interference filter 122 is disposed in the opening, and the reflection is disposed obliquely below the interference filter 122. A plate 126 is provided, and the photographing unit 121 is disposed at a position facing the reflection plate 126. Therefore, after the light emitted from the light source unit 111 passes through the finger and the interference filter 122, it is refracted by the reflection plate 126 and taken into the imaging unit 121.

  (B) As shown in the figure, in this embodiment, a finger is inserted into a tunnel-like opening formed by a first main body 110, a second main body 120, and a pair of support columns 151. This method of inserting a finger into the tunnel-shaped opening has the precision merit of shielding outside light from the surroundings, but it inserts the finger into the opening, so that the user has psychological anxiety. There are challenges. Therefore, in this embodiment, the pair of support columns 151 are provided in the middle and slightly rearward positions, the front part is enlarged, and the rear part is opened slightly smaller so that the shooting accuracy is maintained and used. The anxiety of the person is reduced. That is, according to this structure, since the front surface into which the finger is inserted is greatly opened and the tip of the inserted finger can be desired through the rear opening, the user's anxiety is reduced. On the other hand, since the middle part of the finger, which is a measurement part to be authenticated, is covered by the support parts 151 on both sides, the photographing accuracy can be improved.

  In addition, the guide 125 for guiding the finger setting position is attached so that the front guide 125A and the rear guide 125B are separable, and can be exchanged with other similar members having different concave shapes for finger guidance on the upper surface. . As a result, it is possible to deal with children and adult users with different finger sizes.

  In addition, a recess (not shown) for housing the support column 151 is formed at a position corresponding to the pair of support columns 151 of the second main body 120. This concave portion has a function of a guide rail for moving the column portion 151 in the vertical direction, and a spring (not shown) acting so that the column portion 151 is always maintained at the uppermost portion of the concave portion and a column portion 151. A non-illustrated disengagement prevention means that acts so as not to move beyond the uppermost position, and a locking means (not shown) that maintains the lowermost position when the support column 151 is located at the lowermost position. The locking means employs a known locking means that locks the support column 151 at a position slightly above the bottom when pushed once into the lowermost part and releases the locked state when pushed again within a certain range. ing.

  In FIG. 3, an operation confirmation lamp 112 that is turned on during operation is disposed on the upper surface of the first main body 110. The operation confirmation lamp 112 can notify the user by changing the color, blinking, and the like during standby, reading, and re-reading.

  In FIG. 5, the control unit 9 activates the OS when the information processing apparatus 1A is turned on (step 300), and activates an authentication program previously installed in the information processing apparatus 1A (step 302). When the program is activated, the control unit 9 transmits an activation command signal to the biometric authentication device 100, the switch 160 of the biometric authentication device 100 is in an on state, and the first main body is pulled up and used. Detect whether it is in a state. The switch 160 transmits an on signal in the use state and transmits an off signal in the stored state. When the control unit 9 receives the off signal, the control unit 9 displays a guidance “Please turn finger authentication ON” on the display screen of the display unit as shown in FIG. 7A (step 318).

  On the other hand, when the control unit 9 receives the ON signal, as shown in FIG. 9B, the control unit 9 displays a guidance prompting authentication “please perform authentication”, and turns on the light source unit 111. A standby state is entered (step 306). Then, it is monitored whether or not there is an authentication object (finger) (step 308), and when the finger is inserted, the authentication operation is started and, as shown in FIG. 9 (c), The guidance “authenticating” is displayed (step 310). The control unit 9 determines whether or not the photographed image matches the authentication information stored in advance in the storage device 6 (step 312). If the two pieces of information do not match, the control unit 9 of FIG. ) Guidance for re-authentication shown in the figure is displayed (step 320). If the two pieces of information match, the activation mode is selected. Access shown in FIG. 9 (e) A guidance for prompting selection of a mode is displayed (step 316).

  In this step 316, when “activate this PC” is selected, the control unit 9 displays the desktop screen of this information processing apparatus 1A (step 316). Operate to access the server (step 322).

  In this embodiment, an address of a company server or a home server is stored in the storage unit 6, and when one of the two servers is selected, the control unit 9 selects the server selected from the storage unit 6. To access the selected server together with the authenticated biometric information and activate the information processing apparatus 1A. According to this authentication flow, when accessing another server, this information processing apparatus 1A is activated once and steps such as selecting the address of the server to be accessed can be omitted.

  In addition, the information processing apparatus 1A always monitors a signal from the input unit 8 and a closing signal (off) signal from the biometric authentication apparatus 100 when a desktop screen is displayed and another program is activated. (Step 350). In this monitoring state, when the operation signal from the input unit 8 does not elapse for a certain period of time, or the first main body 120 of the biometric authentication device 100 is pushed and the switch 160 transmits an off signal (close signal). It is monitored whether or not.

  The control unit 9 activates the screen saver when the operation signal from the input unit 8 does not elapse for a certain period of time or when an off signal (close signal) is received (step 352). Then, the control unit 9 sends an ON signal (open signal) from the switch 160 whether or not an operation signal is made via the input unit 8 or the first main body 110 of the biometric authentication device 100 is pulled up. It is monitored whether or not (step 354). Then, when an operation signal is made via the input unit 8 or when an ON signal is received from the switch 160, the control unit 9 activates an authentication program (step 302), which is the same as FIG. Execute the operation flow.

Thus, according to this embodiment, the screen saver can also be activated by changing the form of the biometric authentication device. Therefore, when the user leaves the seat or the interviewer creates the secret information. This is very convenient when you want to hide the currently displayed information in a hurry. And when resuming, since the work can be performed in the same procedure as the cancellation of the normal screen saver, the handling is easy.

  The authentication control unit 162 monitors whether or not an authentication object (finger) has been inserted (step 284), and when detection of the authentication object (finger) is started, reads out the guidance information being authenticated from the memory 161, and This is provided to the control unit 9 (286). Based on this information, the control unit 9 performs a guidance display during authentication on the display unit 3.

  The authentication control unit 162 determines whether the photographed authentication data matches the data stored in the memory 161 in advance (step 288). If the authentication is impossible, the authentication control unit 162 receives the re-authentication guidance display information from the memory 161. It is called and provided to the control unit 9 (step 291). Based on this information, the control unit 9 displays a re-authentication guidance on the display unit 3.

  If authentication is possible, the authentication control unit 162 calls the screen data of the mode selection information from the memory 161 and provides it to the control unit 9. Based on this information, the control unit 9 displays a mode selection screen and monitors whether or not a desktop is selected (step 276). When the desktop is selected, the control unit 9 displays a desktop screen on the display unit 3 (step 278). When a desktop other than the desktop is selected, the control unit 9 requests the authentication control unit 162 to provide address information of the selected server. To do. Upon receiving this request, the authentication control unit 162 provides the address of the corresponding server and authentication related data from the memory 161 to the control unit 9 (step 292). The control unit 9 accesses the corresponding server based on this information (step 280).

  As described above, in this embodiment, authentication and processing related to authentication are performed by the authentication control unit 162, and other processing is performed by the control unit 9, so that the two control units execute authentication processing in cooperation with each other. . In this embodiment, the process of FIG. 6 can also be performed in the same manner as in the first embodiment. According to this embodiment, since the biometric authentication device 110D connected via USB can independently perform processing related to authentication, the information processing device can be authenticated without selecting the information processing device 1A. Therefore, the information processing apparatus is not provided with a storage device, and is effective for an authentication apparatus for an information processing apparatus that accesses a server via a communication line and executes various processes.

  In the first to fourth embodiments, two main bodies are movably connected, and a screen saver drive signal is output in accordance with a change in the form of the two main bodies. The biometric authentication device may be provided with a switch for driving the screen saver without linking the two main bodies movably.

Further, although the steps 314 and 322 are performed in the operation flow described with reference to FIG. 5, the desktop screen may be displayed when the authentication is approved without performing this.
