  FIG. 2 is a functional block diagram showing an outline of the terminal device 1 according to the present embodiment.

  The terminal device 1 is, for example, a portable terminal device such as a mobile phone or a smartphone.

  The terminal device 1 includes a control unit 10, an environment detection unit 20, a communication unit 30, a storage unit 40, a display unit 50 which is a notification unit, a user detection unit 60, and a key 70.

  The environment detection unit 20 includes a temperature sensor, a humidity sensor, and a position information acquisition mechanism.

  The communication unit 30 performs communication such as reception of weather information, map information, and the like from the server 2 via the wireless network 3 under the control of the control unit 10.

  The control unit 10 functions as a use environment determination unit 11, an influence degree determination unit 12, a priority determination unit 13, a display control unit 14 which is a notification control unit, and an authentication unit 15.

  The use environment determination unit 11 determines the use environment of the terminal device 1. The use environment determination unit 11 can determine the use environment of the terminal device 1 with reference to weather information indicating the weather of the use environment of the terminal device 1.

  The influence degree determination unit 12 determines the influence degree on the priority of each of the plurality of authentication units included in the authentication unit 15 according to the use environment.

  The priority determination unit 13 determines the priority of each of the plurality of authentication means included in the authentication unit 15 with reference to the use environment. The priority determination unit 13 determines the priority of the fingerprint authentication unit to be low among the plurality of authentication units when the usage environment is easily wetted.

  The priority determination unit 13 can determine the priority of each of the plurality of authentication means with reference to the degree of influence. Specifically, the priority determination unit 13 can adjust the reference value of the priority of each of the plurality of authentication means with the corresponding degree of influence, and can determine the priority of each of the plurality of authentication means. That is, the priority determination unit 13 determines the order to be presented to the user of each of the plurality of authentication means.

  When the weather of the use environment of the terminal device 1 determined by the use environment determination unit 11 is rainy weather, the priority determination unit 13 determines that the priority of the fingerprint authentication unit is lower among the plurality of authentication units, or the plurality of authentications Among the means, the prohibition of use of the fingerprint authentication means can be determined.

  The display control unit 14 causes the display unit 50 serving as a notification unit to notify the authentication unit in accordance with the determination result of the priority determination unit 13.

  The authentication unit 15 has a plurality of authentication means. The authentication unit 15 performs biometric authentication using the user's biometric authentication information detected by the user detection unit 60 in the locked state.

  The storage unit 40 includes a reference value table 41, a position information table 42, a temperature table 43, a humidity table 44, a precipitation amount table 45, and a determination table 46.

  The reference value table 41, as shown in FIG. 3, is a table that stores the authentication means and the reference value in association with each other. The reference value is set for the authentication means that the accuracy of authentication may decrease due to the influence of weather conditions. The reference value is a standard of the certainty of the authentication, and is a value serving as a reference of the value to be judged when the appropriate degree as the authentication means is judged. The standard value is determined for each certification method. In the example shown in FIG. 3, the reference value of fingerprint authentication is 100. Although only the reference value of fingerprint authentication is shown in FIG. 3, reference values of other authentication means may be set. Moreover, the reference value of each authentication means may be set to the same value uniformly.

  The position information table 42, as shown in FIG. 4B, indicates information indicating the combined position of longitude, latitude, and altitude, information indicating whether the position is indoor or outdoor, and the degree of influence at the position. It is a table which matches and stores a value. For example, as shown in (a) of FIG. 4, when the current position is a position indicated by P, the position information acquisition mechanism included in the environment detection unit 20 acquires the longitude, latitude, and altitude of the position P. , Position information table 42 stores. Further, it refers to the map information including the position P, determines that the current position is outside, and stores the position information table 42. Further, the position information table 42 stores the degree of influence at the position P. The degree of influence will be described later.

  As shown in FIG. 5, the temperature table 43 is a table that stores the temperature range and the corresponding humidity table to be referenced in association with each other. That is, the humidity table to be referred to differs depending on the temperature. In the example shown in FIG. 5, when the temperature exceeds 35 ° C., the use environment determination unit 11 refers to the humidity table 1. When the temperature is 30 to 35 ° C., the use environment determination unit 11 refers to the humidity table 2. When the temperature is 25 to 30 ° C., the use environment determination unit 11 refers to the humidity table 3. When the temperature is 20 to 25 ° C., the use environment determination unit 11 refers to the humidity table 4. When the temperature is 15 to 20 ° C., the use environment determination unit 11 refers to the humidity table 5. When the temperature is 10 to 15 ° C., the use environment determination unit 11 refers to the humidity table 6. When the temperature is lower than 10 ° C., the use environment determination unit 11 refers to the humidity table 7.

  The humidity table 44, as shown in FIG. 6, is a table that stores humidity (%) and the degree of influence in association with each other. The humidity table 44 includes the humidity table 1 (441) shown in (a) of FIG. 6, the humidity table 2 (442) shown in (b) of FIG. 6, the humidity table 3 (443) shown in (c) of FIG. The humidity table 4 (444) shown in (d) of FIG. 6, the humidity table 5 (445) shown in (e) of FIG. 6, the humidity table 6 (446) shown in (f) of FIG. The humidity table 7 (447) shown in g) is included. The influence degree determination unit 12 can determine the influence degree from the humidity with reference to the humidity table 44. In the example shown in FIG. 6A, the degree of influence is 60 when the humidity exceeds 90%. Also, when the humidity is 80 to 90%, the degree of influence is 50. Moreover, the influence degree in the case of 40 to 80% of humidity is 25. In addition, when the humidity is less than 40%, the degree of influence is 10. In the example shown in (b) of FIG. 6, the degree of influence is 50 when the humidity exceeds 90%. In addition, when the humidity is 80 to 90%, the degree of influence is 40. Moreover, the influence degree in the case of 40 to 80% of humidity is 20. In addition, when the humidity is less than 40%, the degree of influence is 10. In the example shown in FIG. 6C, the degree of influence is 40 when the humidity exceeds 90%. Also, when the humidity is 80 to 90%, the degree of influence is 25. Moreover, the influence degree in the case of 70 to 80% of humidity is five. Also, when the humidity is less than 70%, the degree of influence is zero. In the example shown in (d) of FIG. 6, the degree of influence is 30 when the humidity exceeds 90%. Also, when the humidity is 80 to 90%, the degree of influence is 10. Moreover, the influence degree in the case of 30 to 80% of humidity is zero. Moreover, the influence degree in the case of 20 to 30% of humidity is five. In addition, when the humidity is 10 to 20%, the degree of influence is 10. Also, when the humidity is less than 10%, the degree of influence is 15. In the example shown in (e) of FIG. 6, the degree of influence is 20 when the humidity exceeds 90%. Also, when the humidity is 80 to 90%, the degree of influence is 10. Moreover, the influence degree in the case of 30 to 80% of humidity is zero. Moreover, the influence degree in the case of 20 to 30% of humidity is five. In addition, when the humidity is 10 to 20%, the degree of influence is 10. Also, when the humidity is less than 10%, the degree of influence is 20. In the example shown in (f) of FIG. 6, the degree of influence is 15 when the humidity exceeds 90%. In addition, when the humidity is 80 to 90%, the degree of influence is five. Moreover, the influence degree in the case of 30 to 80% of humidity is zero. Moreover, the influence degree in the case of 20 to 30% of humidity is five. In addition, when the humidity is 10 to 20%, the degree of influence is 15. Also, when the humidity is less than 10%, the degree of influence is 30. In the example shown in (g) of FIG. 6, the degree of influence is 15 when the humidity exceeds 90%. In addition, when the humidity is 80 to 90%, the degree of influence is five. Moreover, the influence degree in the case of 30 to 80% of humidity is zero. Moreover, the influence degree in the case of 20 to 30% of humidity is five. Also, when the humidity is 10 to 20%, the degree of influence is 20. Also, when the humidity is less than 10%, the degree of influence is 35.

  That is, when the temperature is less than 25 ° C., the value of the humidity table 44 is set so that the degree of influence is large when the use environment of the terminal device 1 is an environment that is easily dried. Then, when the use environment of the terminal device 1 is an environment that tends to dry, the priority determination unit 13 can determine that the priority of the fingerprint authentication unit is low among the plurality of authentication units.

  As shown in FIG. 7, the precipitation amount table 45 is a table that stores the amount of precipitation (mm / h) and the degree of influence in association with each other. The influence degree determination unit 12 can determine the influence degree from the amount of precipitation with reference to the precipitation table 45. In the example shown in FIG. 7, the degree of influence is 0 when the amount of precipitation is 0 to 1 mm / h. The degree of influence is 5 when the amount of precipitation is 1 to 2 mm / h. The degree of influence is 10 when the amount of precipitation is 2 to 5 mm / h. Also, the degree of influence is 50 when the amount of precipitation exceeds 5 mm / h.

  As shown in FIG. 8, the determination table 46 is a table that stores the adjusted reference value and the determination in association with each other. The priority determination unit 13 can refer to the determination table 46 and determine from the adjusted reference value. In the example illustrated in FIG. 8, when the adjusted reference value exceeds 90, the priority determination unit 13 determines as A. When the adjusted reference value is 70 to 90, the priority determination unit 13 determines that the value is B. When the adjusted reference value is 60 to 70, the priority determination unit 13 determines that the value is C. When the adjusted reference value is 50 to 60, the priority determination unit 13 determines that the value is D. When the adjusted reference value is less than 50, the priority determination unit 13 determines that the value is E. For example, A is fine, B may not succeed at one time, but can be used as an authentication means, C may need to be tried multiple times, D is preferably to select other authentication means, If the number of trials is repeated, authentication may be possible but it is not recommended as an authentication means. E indicates that it is not possible because it is desirable to avoid as an authentication means. The adjusted reference value is a reference value adjusted by subtracting a value indicating the degree of influence from the reference value.

  The temperature table 43, the humidity table 44, the precipitation amount table 45, and the determination table 46 are tables corresponding to fingerprint authentication. A table for referencing the degree of influence can also be prepared for each of the authentication means for which other reference values are set. Further, in the position information table 42, the influence degree is stored for each authentication means for which the reference value is set.

  Further, each of the temperature table 43, the humidity table 44, the precipitation amount table 45, and the determination table 46 may be stored in the server 2 and acquired via the communication unit 30 and the wireless network 3.

  The display unit 50 is provided on one side of the terminal device 1. The display unit 50 can be a touch panel, and obtains notification of information to the user and input information from the user.

  The user detection unit 60 is an organization for acquiring authentication information. For example, a fingerprint sensor, a camera, a microphone, etc. can be included.

  The key 70 receives an input operation from the user.

  Subsequently, control in the terminal device 1 according to the present embodiment will be described with reference to FIGS. 9 to 14. FIG. 9 is a flowchart illustrating an example of control in the terminal device 1 according to the present embodiment.

  When control unit 10 receives a predetermined input operation from the user (depression of key 70, touch on display unit 50, etc.), control in terminal device 1 is started.

  In step S2, the control unit 10 confirms the reference value of the reference value table 41. Details of the process in step S2 will be described later with reference to FIG.

  In step S4, the control unit 10 determines the current position of the terminal device 1. The details of the process in step S4 will be described later with reference to FIG.

  In step S6, the control unit 10 determines the degree of influence. The details of the process in step S6 will be described later with reference to FIG.

  In step S8, the control unit 10 determines the priority. Details of the process in step S8 will be described later with reference to FIG.

  In step S10, the control unit 10 notifies the recognition means. Details of the process in step S10 will be described later with reference to FIG.

  The process of confirming the reference value by the control unit 10 will be described with reference to FIG.

  In step S22, the control unit 10 reads the reference value associated with the authentication unit from the reference value table 41 of the storage unit 40.

  In step S24, the control unit 10 determines whether the reference value associated with the authentication unit has been acquired. When the reference value can be acquired, the control unit 10 ends the confirmation process of the reference value. If the reference value can not be acquired, the process proceeds to step S26. Here, the control unit 10 determines that the reference value could not be acquired even when the reference value associated with the part of the authentication means can be acquired.

  In step S <b> 26, the control unit 10 acquires, from the server 2, the reference value associated with the authentication unit that could not be acquired, via the communication unit 30.

  In step S <b> 28, the control unit 10 stores the reference value acquired in step S <b> 26 in the reference value table 41 of the storage unit 40.

  Next, determination processing of the current position by the control unit 10 will be described with reference to FIG.

  In step S42, the position information acquisition mechanism included in the environment detection unit 20 measures the position.

  In step S44, it is determined whether the position information acquisition mechanism included in the environment detection unit 20 has acquired position information. If the position information is acquired, the process proceeds to step S46. If the position information has not been acquired, the process proceeds to step S50.

  In step S46, the control unit 10 acquires map information including the acquired position information from the server 2 via the communication unit 30 and the wireless network 3.

  In step S48, the control unit 10 refers to the acquired map information, and determines whether the current position indicated by the position information is indoors.

  In step S50, since the position information acquisition mechanism included in the environment detection unit 20 did not acquire position information, the control unit 10 determines that the current position is a place where the position information can not be measured, that is, an indoor.

  In step S <b> 52, the control unit 10 stores the determination result as to whether or not the room is indoors in the position information table 42 of the storage unit 40.

  If the current position is outside the room (YES in step S54), control unit 10 acquires weather information indicating the weather of the area indicated by the position information from server 2 via communication unit 30 and wireless network 3 (Step S56).

  If the current position is indoors (NO in step S54), control unit 10 ends the process of determining the current position.

  The control unit 10 may periodically acquire weather information instead of acquiring the weather information when the priority determination unit 13 determines the priority of each of the plurality of authentication means.

  Next, the process of determining the degree of influence by the influence degree determination unit 12 will be described with reference to FIG.

  In step S 62, the influence degree determination unit 12 acquires the position information table 42 from the storage unit 40.

  In step S64, the influence degree determination unit 12 determines whether the information indicating the outdoor is stored in the position information table 42 or the information indicating the indoor is stored. If the information indicating the outdoor is stored, the process proceeds to step S66. If the information indicating the room is stored, the influence degree determination unit 12 ends the influence degree determination process.

  That is, the use environment determination unit 11 determines whether the use environment of the terminal device 1 is outdoor, and the priority determination unit 13 determines the priority of each of the plurality of authentication means with reference to the use environment. For example, when the use environment determination unit 11 determines that the use environment of the terminal device 1 is outdoor, the priority determination unit 13 determines the priority of each of the plurality of authentication means according to the use environment.

  In step S66, the influence degree determination unit 12 compares the information indicating the temperature included in the weather information acquired in step S56 with the temperature table 42 of the storage unit 40, and which humidity table 1 to 7 correspond to Determine Alternatively, the influence degree determination unit 12 compares the temperature detected by the temperature sensor included in the environment detection unit 20 with the temperature table 42 of the storage unit 40, and determines which one of the humidity tables 1 to 7 corresponds to. .

  In step S68, the influence degree determination unit 12 refers to any one of the determined humidity tables 1 to 7 to determine the influence degree. The influence degree determination unit 12 compares the information indicating the humidity included in the weather information acquired in step S56 with any of the determined humidity tables 1 to 7 to determine the influence degree. Alternatively, the influence degree determination unit 12 compares the humidity detected by the humidity sensor included in the environment detection unit 20 with any of the determined humidity tables 1 to 7 to determine the influence degree.

  In step S70, the influence degree determination unit 12 compares the information indicating the amount of precipitation included in the weather information acquired in step S56 with the precipitation amount table 45 of the storage unit 40, and determines the degree of influence.

  In step S 72, the influence degree determination unit 12 stores the sum of the influence degrees determined in step S 68 and step S 70 in the position information table 42 of the storage unit 40. For example, if the temperature of the use environment of the terminal device 1 is 31 ° C., the humidity is 85%, and the amount of precipitation is 4 mm / h, the humidity table 2 is selected and the degree of influence determined by the temperature and humidity Is 40. In addition, the degree of influence determined by the amount of precipitation is 10. The degree of influence stored in the position information table 42 of the storage unit 40 is 50.

  Next, the process of determining the priority of the authentication unit by the priority determination unit 13 will be described with reference to FIG.

  In step S 82, the priority determination unit 13 acquires the reference value table 41, the position information table 42, and the determination table 46 from the storage unit 40.

  In step S84, the priority determination unit 13 refers to the position information table 42 and determines whether the current position is outside the room. If outside the room, the process proceeds to step S86. If it is indoors, the process proceeds to step S88.

  In step S86, the priority determination unit 13 adjusts the reference value by subtracting the degree of influence stored in the position information table 42 from the reference value stored in the reference value table 41. Then, the priority determination unit 13 refers to the determination table 46, and determines the determination corresponding to the adjusted reference value, that is, one of A to E shown in the determination table of FIG. 8 as the determination result. This process is performed for each authentication means.

  For example, when the influence degree is 50, since the fingerprint authentication reference value is 100, the adjusted reference value is 50. Therefore, it is desirable to select D, ie, another authentication means, and fingerprint authentication may be possible to be authenticated after repeated attempts, but it is determined not to be recommended as an authentication means.

  In step S88, the priority determination unit 13 fixes A shown in the determination table of FIG. 8 as the determination result.

  Next, with reference to FIG. 14, notification processing of the authentication unit by the display control unit 14 will be described.

  In step S102, the display control unit 14 acquires the determination result of the priority determination unit 13.

  In step S104, the display control unit 14 causes the display unit 50 to notify the authentication unit according to the determination result. The display control unit 14 can notify the authentication means in the descending order of the reference value. Further, the display control unit 14 can notify only the authentication means of which the reference value is higher. In addition, the display control unit 14 can notify an authentication unit having a predetermined reference value or more.

  In addition, when the control unit 10 determines that the authentication by the biometric authentication means is not possible, the display control unit 14 may cause the display unit 50 to display an alternative authentication object for causing the user to input the authentication information. it can. For example, nine dots equally spaced in two dimensions may be displayed as an alternative authentication object. In this case, at the start of use of the terminal device 1, the user may cause the user to sequentially touch a plurality of dots as initial processing, and the control unit 10 may store the pattern of the touch order of the user in the storage unit 40 as verification information for comparison. . At the time of authentication, the user's touch of each dot may be matched with the stored pattern to authenticate the user.

  In the above embodiment, the influence degree of both the temperature and the humidity of the use environment of the terminal device 1 and the precipitation amount of the use environment of the terminal device 1 is determined. However, the influence degree determination unit 12 only needs to determine the influence degree according to at least one of the temperature and the humidity of the use environment of the terminal device 1 and the precipitation amount of the use environment of the terminal device 1.

The control block of the terminal device 1 (especially the use environment determination unit 11 and the priority determination unit 13) may be realized by a logic circuit (hardware) formed in an integrated circuit (IC chip) or the like, or realized by software. You may

The computer includes, for example, at least one processor (control device) and at least one computer readable storage medium storing the program. Then, in the computer, the processor reads the program from the recording medium and executes the program to achieve the object of the present invention.
