Description

  The present invention relates to an information processing apparatus such as a personal computer (hereinafter referred to as a personal computer) and a mobile communication terminal, and more particularly to an information processing apparatus for improving the security of information displayed on a monitor and a control method thereof.

  In general, measures are taken to increase security in personal computers and mobile phones by performing authentication at the time of startup to eliminate operations by persons other than legitimate users. However, once activated, information is displayed on the monitor screen, so that an unrelated third party or suspicious person can peep at it and can operate the personal computer. Also, when operating a mobile terminal on a train, it is easy to look into the mobile screen from behind. Therefore, various techniques for preventing such peeping on the monitor screen have been proposed.

  For example, Patent Document 1 discloses a security system in which a personal sensor is provided on a personal computer, and when the user removes his / her seat, the display on the display automatically disappears and the screen does not return unless authenticated by biometric information or the like.

  The portable terminal disclosed in Patent Document 2 registers a user's iris pattern in advance, and captures a predetermined range on the display unit side with a camera to extract the iris pattern of a person in that range. Then, it is determined whether or not the extracted iris pattern matches the registered one, and if it does not match, it is determined that a person other than the user may be looking into the display unit and a warning screen is displayed on the display unit To do.

  The peep prevention device disclosed in Patent Document 3 has a human sensor, and when an unspecified person other than an operator is detected, a peep is displayed by displaying a cue on a personal computer screen or changing the screen to be unreadable. Prevent viewing.

Japanese Patent No. 3031637 JP 2003-264877 A JP 2010-122754 A

  However, in the method of Patent Document 1 described above, the screen is erased when the user leaves the seat, so the screen when the user is seated and operating remains unprotected.

  Further, in the method of Patent Document 2, since the iris pattern determination is uniformly performed and a warning is displayed for a person within the range captured by the camera, the same warning is frequently generated and the operation is stopped. Besides being bothersome, it is not possible to display warnings according to the situation. In particular, since it is not possible to determine the level of possibility that the display information is peeped, the frequency of issuing unnecessary warnings increases. On the other hand, although the possibility that the suspicious person is peeping is very high, the same warning as when the possibility is low is displayed.

In the method of Patent Document 3,
SUMMARY OF THE INVENTION An object of the present invention is to provide an information processing apparatus and a control method thereof that can give a peep prevention warning according to the situation and can obtain high security.

FIG. 7 is a sequence diagram for explaining the operation of the security system according to the second embodiment.

  According to the present invention, when a suspicious person looks into the personal computer, a warning function for preventing peeping is activated according to the presence rate of the regular user. Specifically, when a computer user is using a computer without noticing that a suspicious person is peeping, a warning screen is automatically displayed and a warning sound is sounded by the peep prevention function. The user's attention is urged. When a user is actually using a personal computer, if the personal computer suddenly stops working, business operations will be hindered, so the warning function that stops the personal computer operation is not activated. On the other hand, if a suspicious person looks in when there is a possibility that the user is in front of the personal computer but is not using it, the display is automatically turned off and the personal computer is put into a hibernation state. If the user inadvertently leaves the screen with confidential information displayed on the computer screen, the peep prevention function automatically turns off the display and automatically turns on the computer when the suspicious person looks into it. It is possible to prevent information leakage by turning it off.

  Hereinafter, a desktop personal computer will be described as an example of an information processing apparatus according to an embodiment of the present invention. However, this is an example, and the present invention has a display unit such as a mobile personal computer, a personal digital assistant, or a mobile phone. It can be applied to information equipment having a processing function.

1. 1. First Embodiment 1.1) Configuration As shown in FIG. 1, a personal computer main body 13 that is an information processing apparatus according to a first embodiment of the present invention has a built-in speaker 14 and a display 10 and a camera 12 embedded in a display frame 11. It is assumed that the keyboard 15 is connected to a fingerprint sensor 17 incorporated in a pointing device 16 such as a mouse.

  The display 10 has a function of displaying a screen of a document file created by a personal computer, a screen of a WEB browser, and various other screens. In addition to the display screen, the display frame 11 has a camera 12 on the front surface. The camera 12 has a function of photographing the iris of a person whose face is close to the display and transmitting image data (iris data) to the personal computer main body 13. The keyboard 15 has a function of transmitting character input information corresponding to the key pressed by the user to the personal computer body 13. The pointing device 16 and the fingerprint sensor 17 have a function of reading a fingerprint shape of a person who operates the pointing device and transmitting fingerprint data to the personal computer main body 13. As will be described later, the personal computer body 13 receives image data from the camera 12 and writes iris information to the memory, receives image data from the pointing device 16 and writes fingerprint information to the memory, and turns off the display 10 when a peep is detected. And a function for forcibly turning off the personal computer, a function for instructing the display 10 to display a peep warning screen, and the like.

  In the present embodiment, two types of biometric authentication, i.e., iris authentication by a camera and fingerprint authentication by a fingerprint sensor, are used in combination. The iris authentication is non-contact, but the fingerprint authentication makes the user's finger belly contact the fingerprint sensor. Thus, by using non-contact authentication and contact authentication together, it is possible to improve the accuracy of determination of the attendance rate described later.

  If the information processing apparatus is a portable information terminal, the same functional units as those of the camera 12, the display 10, and the fingerprint sensor 17 may be provided on the operation surface side of the portable terminal.

  2, the personal computer main body 13 (information processing apparatus) according to the present embodiment includes an iris information generation unit 101 that generates iris information from image data of the camera 12 and a fingerprint that generates fingerprint information from image data of the fingerprint sensor 17. An information generation unit 102 is provided, and the iris information and fingerprint information are output to the authentication unit 103. The authentication unit 103 collates the registration function for registering the input iris information and fingerprint information in the authentication information registration unit 104 with the input iris information and / or fingerprint information and the registered iris information and / or registered fingerprint information. And an authentication function for performing authentication, and outputs the authentication result to the determination processing unit 105. As will be described later, the determination processing unit 105 has an update function of the presence rate determination flag 106 and a determination function that determines the type of warning according to the presence rate, and outputs the determination result to the warning control unit 107. To do. The warning control unit 107 outputs drive control of the display 10 and / or the speaker 14 and a pause request / power-off request to the CPU according to a warning display according to the determination result.

  The authentication information registration unit 104 is a memory in the PC main body 13, and includes an iris information generation unit 101, a fingerprint information generation unit 102, an authentication unit 103, a determination processing unit 105, an attendance rate determination flag 106, and a warning control unit 107. Each function and other control functions are realized by executing a program stored in a memory (not shown) in the personal computer main body 13 on a program control processor such as a CPU (Central Processing Unit). As is well known, the display 10, the camera 12, the keyboard 15, the pointing device 16 and the fingerprint sensor 17 are controlled by a CPU in the personal computer main body 13. The operation of the present embodiment will be described with reference to the above-described camera 12, with reference to FIGS.

1.2) Overall Operation As shown in FIG. 3, when the personal computer is first turned on (step 201), the authentication unit 103 checks whether or not authentication information has been registered (step 202). If not registered (NO in step 202), authentication information registration processing 203 is executed.

  A specific example of the authentication information registration process 203 is as follows. First, the user's eyes are photographed by the camera 12, the iris information generating unit 101 generates iris information from the eye image, and the fingerprint sensor 17 reads the fingerprint image of the user's finger in the same manner. Fingerprint information is generated from the fingerprint image, and the generated iris information and fingerprint information are registered in the authentication information registration unit 104. This completes the preparations.

  If the authentication information has been registered, the determination processing unit 105 repeats the attendance rate determination process 204 and the suspicious person determination process 205 described below at a predetermined cycle or upon request until the power is turned off (step 206). ).

1.3) Determination of attendance rate In FIG. 4, the determination processing unit 105 prepares an attendance rate determination flag F as an index for obtaining the attendance rate, and sets a predetermined value n (an integer of 2 or more). (Step 301). Here, since two authentications of iris authentication and fingerprint authentication are performed, n = 2.

  Subsequently, the determination processing unit 105 instructs the authentication unit 103 to execute iris authentication, and requests the result (step 302). As described above, the iris authentication is executed by comparing the input iris information generated from the imaging data of the camera 12 and the registered iris information registered in the authentication information registration unit 104. If they match, the display 10 Since the face that is close to is a regular user's face, it is regarded as authentication success, and when the face does not match, the face that is close to the display 10 is not a regular user's face and is regarded as authentication failure. The determination processing unit 105 determines the authentication result from the authentication unit 103 (step 303). If the authentication fails, the value of the presence rate determination flag F is subtracted by 1 (step 304). The value of the rate determination flag F is maintained.

  Similarly, the determination processing unit 105 instructs the authentication unit 103 to execute fingerprint authentication and requests the result (step 305). As described above, the fingerprint authentication is performed by collating the input fingerprint information generated from the image data of the fingerprint sensor 17 with the registered fingerprint information registered in the authentication information registration unit 104. Since the hand touching the device 17 is a legitimate user's hand, it is regarded as an authentication success, and if they do not match, the hand touching the pointing device 17 is regarded as an authentication failure because the hand is not a legitimate user's hand. The determination processing unit 105 determines the authentication result from the authentication unit 103 (step 306). If the authentication is unsuccessful, the determination unit 105 subtracts 1 from the presence rate determination flag F (step 307). The value of the rate determination flag F is maintained.

  The determination processing unit 105 determines the final value of the attendance rate determination flag F obtained in this way (step 308), and determines a higher attendance rate P as the final value is larger (steps 309-311). ). For example, two different thresholds are prepared. If F is larger than the upper threshold, the high seating rate is set. If F is between the two thresholds, the middle seating rate is set. Set the seating rate for each.

  As another example, when F = 2 is initialized in step 301, if F = 2 in step 308, both iris authentication (step 302) and fingerprint authentication (step 305) are successful. Therefore, the attendance rate P is set to “high” (S309). If F = 1 in step 308, authentication has failed in either iris authentication or fingerprint authentication, so the attendance rate P is set to “medium” (S310). If F = 0 in step 308, the authentication has failed in both iris authentication and fingerprint authentication, so the attendance rate P is set to "low" (S311). By reflecting the success / failure of the non-contact authentication and the contact authentication in this way, it is possible to improve the presence rate determination accuracy.

  However, dividing the attendance rate P into high / medium / low is an example and can be divided into arbitrary stages. For example, the initial value of the attendance rate determination flag F is set to a value of 3 or more, and each authentication result by the 3 or more biometric authentication means is reflected by a decrease in F (steps 304 and 307). It is also possible to divide the rate P into four or more stages. As a method for reflecting the authentication result, the amount of decrease in F can be set with different weights for each authentication means. Further, as a method of decreasing the value of the attendance rate determination flag F, not only subtraction but also a value less than 1 may be multiplied.

  The attendance rate P dynamically changes depending on how the personal computer user uses the personal computer. For example, iris authentication may fail if the face is turned away from the screen, and fingerprint authentication may fail if the hand is released from the mouse or the grip is weak. Therefore, it is desirable that the personal computer updates the attendance rate P by automatically repeating iris authentication (step 302) and fingerprint authentication (step 305) after a certain period of time has elapsed. For example, by repeating the attendance rate determination process 204 in steps 301-311 at regular intervals, it is possible to improve the presence rate determination accuracy.

1.4) Suspicious Person Determination In FIG. 5, it is first determined whether or not the face is close to the display 10 and the camera 12 is close enough to allow iris photography (step 401). If the faces are close (YES in step 401), the eyes of the face are photographed by the camera 12 and iris authentication is performed (step 402). The iris authentication is as described above. If the result of the iris authentication is successful (“success” in step 403), the approaching face is determined to be a regular user's face, and the user's operation is permitted as it is.

  If the result of the iris authentication is failure (“failure” in step 403), the determination processing unit 105 checks the current value of the attendance rate determination flag 106 (step 404). If the attendance rate P is “high”, it is determined that the authorized user is currently using the computer in front of the personal computer, and the determination processing unit 105 instructs the warning control unit 107 to warn that “the suspicious person is peeped”. Is displayed on the display 10 and a warning sound is emitted from the speaker 14 (step 405). If the attendance rate P is “medium”, the determination processing unit 105 instructs the warning control unit 107 to turn off the display 10 and the personal computer main body 13 also automatically shifts to a sleep state (step 406). If the attendance rate is “low”, there is a high possibility that a legitimate user is not presently in front of the personal computer. Therefore, the determination processing unit 105 instructs the warning control unit 107 to turn off the display 10 and the personal computer main body 13 is also displayed. It automatically turns itself off (step 407). Alternatively, the volume of the warning sound from the speaker 14 may be changed according to the presence / absence rate P.

  Even when the attendance rate P is set to four or more levels, warning display and state transition corresponding to each level may be set. For example, the warning level of this function can be changed in a plurality of stages. This multi-stage switching can minimize the effect of the peeping prevention function on work.

1.5) Effect According to the first embodiment of the present invention, if a suspicious person peeks at the display of a personal computer, the camera captures the suspicious person's iris and the iris authentication fails. The warning level changes depending on the attendance rate, such as displaying a warning screen, sounding a warning sound, forcibly turning off the display, or turning off the computer automatically according to the attendance rate Information leakage due to peeping can be effectively prevented. Specifically, the following effects can be obtained.

  First, when a legitimate user looks into from behind while using a personal computer, a warning screen can be automatically displayed on the display and a warning sound can be generated to alert the personal computer user. As a result, the user can quickly take measures such as closing the screen containing the confidential information and turning off the display, and can prevent leakage of information displayed on the display.

  Second, even if a legitimate computer user inadvertently leaves the screen with confidential information on the display, even if the suspicious person looks into the computer, the display automatically turns off when the iris of the suspicious person is detected. Since the power is automatically cut off, it is possible to prevent leakage of information displayed on the display.

  Third, by dynamically changing the warning content of the warning function depending on the attendance rate of regular users, it is possible to minimize the influence on work actually performed using a personal computer.

2. Second Embodiment In the first embodiment described above, the iris information and fingerprint information are stored in the authentication information registration unit 104, which is a memory built in the personal computer body. However, if the personal computer is stolen, Fingerprint information will be stolen together. Therefore, it is possible to adopt a method in which these pieces of information are stored in an external database without being stored in the personal computer body, and the database is inquired as necessary. Hereinafter, as the second embodiment, an information processing apparatus using an external authentication system will be described.

2.1) Configuration As shown in FIG. 6, the personal computer main body 13a according to the present embodiment includes a control unit 108 in place of the authentication unit 103 and the authentication information registration unit 104 in the functional blocks of the personal computer main body 13 shown in FIG. A communication unit 109 is provided. The other functional units are the same as those in FIG. The communication unit 109 can communicate with an external authentication server 501 through a cable or a network. A database 502 storing authentication information is connected to the authentication server 501. In the present embodiment, the same registration function and authentication function as the authentication unit 103 and the authentication information registration unit 104 shown in FIG. 2 are realized by the control unit 108, the communication unit 109, the authentication server 501, and the database 502.

2.2) Operation The basic operation of the system shown in FIG. 6 is as described with reference to the flowchart of FIG. 3, but the authentication information registration process 203, the attendance rate determination process 204, and the suspicious person determination process 205 iris authentication. And the operation of fingerprint authentication is different. Hereinafter, different operations will be described.

  7, in the authentication information registration processing 203, as described above, first, the camera 12 captures the eyes of the user, and the iris information generation unit 101 generates iris information from the eye image. Then, the fingerprint image of the user's finger is read, and the fingerprint information generator 102 generates fingerprint information from the fingerprint image. When acquiring the iris information and the fingerprint information (step 601), the control unit 108 accesses the authentication server 501 through the communication unit 109 and requests registration of the authentication information. The authentication information registration request signal includes the personal identification number of the authorized user as well as iris information and fingerprint information. Upon receiving the authentication information registration request signal, the authentication server 501 transmits the received personal identification number, iris information, and fingerprint information to the authentication database 502. The authentication database 502 registers iris information and fingerprint information in a table format using the personal identification number as a search key (step 602). When the registration is completed, a registration completion notification is transmitted from the authentication database 502 to the personal computer main body 13a via the authentication server 501, and the authentication information registration process 203 ends.

  The procedures of iris authentication (step 302 in FIG. 4 and step 402 in FIG. 5) and fingerprint authentication processing (step 305 in FIG. 4) in this embodiment are basically the same. explain.

  In FIG. 7, when iris / fingerprint authentication is started (step 603), the control unit 108 transmits an authentication request signal including the input iris / fingerprint information and the personal authentication number of the authorized user to the authentication server 501. . The authentication server 501 transmits a search request using the received personal authentication number as a search key to the authentication database 502. The authentication database 502 searches for the registered iris / fingerprint information using the received personal authentication number as a key, and returns this registered iris / fingerprint information to the authentication server 501. The authentication server 501 collates the input iris / fingerprint information received from the personal computer main body 13a with the registered iris / fingerprint information received from the authentication database 502, and determines whether or not the input iris / fingerprint information is legitimately for the user. (Step 603). The authentication server 501 returns an authentication response signal including the personal authentication number requested for authentication and the authentication result to the personal computer main body 13a. The control unit 108 of the personal computer main body 13a outputs the authentication result to the determination processing unit 105 and ends the authentication (step 604).

  The determination processing unit 105 executes the attendance rate determination process 204 and the suspicious person determination process 205 described above by using the above-described iris authentication and fingerprint authentication. These processes are described in FIGS. 4 and 5. Since it is as it is, description is abbreviate | omitted.

2.3) Effects According to the second embodiment of the present invention, personal iris information and fingerprint information are stored in the external authentication server 501 and the database 502 without being stored in the personal computer main body 13a, and are stored in the database as necessary. Since the method for requesting the search is adopted, in addition to the effect of the first embodiment described above, there is an advantage that it is possible to safely protect iris information and fingerprint information which are confidential information even if the personal computer is stolen. is there.

3. Other Embodiments As another embodiment, instead of embedding the installation location of the camera 12 in the outer frame 11 of the display 10, a more sensitive camera may be grounded as an external camera on the display frame 11.

  As an application example of the present invention, an iris authentication camera can be installed around the screen of a mobile phone, which can be used to prevent peeping of the mobile phone. Also, even if you are peeping from behind while reading a confidential paper document, the present invention can detect the suspicious person and sound a warning sound to notify the person who is reading the document the existence of the suspicious person. Is possible. Furthermore, even if the user is not peeping, it is possible to alert the user by sounding a warning sound when the PC user looks away or by sounding a warning sound when he falls asleep.

  As described above, according to the present invention, it is possible to change the warning content for peeping according to the presence rate of the regular user and the iris authentication failure for the suspicious person.
