In the description of the flowchart shown in FIG. 8, the number of holding methods detected from the information input unit 204 is “3” and the association information of the association pattern “1” is input. Based on the above, the number is “1” for the combination of holding sideways and swinging direction + X direction, the number “2” for the combination of holding sideways and swinging direction −X direction, and holding way sideways In addition, the combination of the swing direction + Y direction is the number “3”, the holding method is the horizontal holding and the swing direction is the number “4”, the combination is the horizontal holding and the swing direction is the + Z direction combination. No. “5”, number “6” for a combination of horizontal holding and swinging direction −Z direction, “7” for a combination of vertical holding and swinging direction + X direction, Vertical holding and swinging direction is -X direction Number “8” for matching, number “9” for the combination of holding vertically and swinging direction + Y direction, number “10” for combination of holding vertically and swinging direction −Y direction The number is “11” for the combination with the vertical holding direction and the swing direction is + Z direction, the number “12” is the combination with the vertical holding direction and the swing direction is −Z direction, the holding direction is the handshake and the swing direction is The number “13” for the combination in the + X direction, the number “14” for the combination in which the holding method is the handshake and the swing direction is −X direction, and the number “15” in the combination in which the holding method is the handshake and the swing direction is the + Y direction , The way to hold is handshake and the swing direction is the number “16” for the combination in the −Y direction, the way to hold is handshake and the swing direction is the number “17” for the combination in the + Z direction, the way to hold is the handshake Direction is -Z direction It is assumed that you set the number "18" on the combination.

  Subsequently, in step S <b> 102, the authentication processing unit 209 performs processing for reading the password of the authentication registrant stored in the password storage unit 202.

If 1G acceleration is measured in the −Z direction by the acceleration sensor 201 as a result of the determination in step S105 (S105 / YES), the process proceeds to step S106.
In step S106, the holding method detection unit 206 detects horizontal holding as a method of holding the casing 100-K of the mobile terminal device by the user.

  On the other hand, if 1G acceleration is not measured in the −Z direction by the acceleration sensor 201 as a result of the determination in step S105 (S105 / NO), the process proceeds to step S107.

  In step S107, the holding state detection unit 206 determines whether or not 1G acceleration is measured in the −Y direction by the acceleration sensor 201 as illustrated in FIG. 6B.

If 1G acceleration is measured in the −Y direction by the acceleration sensor 201 as a result of the determination in step S107 (S107 / YES), the process proceeds to step S108.
In step S108, the holding method detection unit 206 detects vertical holding as a method of holding the casing 100-K of the mobile terminal device by the user.

  On the other hand, if 1G acceleration is not measured in the −Y direction by the acceleration sensor 201 as a result of the determination in step S107 (S107 / NO), the process proceeds to step S109.

  In step S109, the holding method detection unit 206 determines whether or not 1G acceleration is measured in the + X direction by the acceleration sensor 201 as illustrated in FIG. 6C.

As a result of the determination in step S109, when 1G acceleration is measured in the + X direction by the acceleration sensor 201 (S109 / YES), the process proceeds to step S110.
In step S110, the holding method detection unit 206 detects holding a handshake as a method of holding the casing 100-K of the mobile terminal device by the user.

  On the other hand, if 1G acceleration is not measured in the + X direction by the acceleration sensor 201 as a result of the determination in step S109 (S109 / NO), the process returns to step S105, and the processes in and after step S105 are performed again.

If the process of step S106, the process of step S108, or the process of step S110 is completed, the process proceeds to step S111.
In step S111, the swing direction detection unit 207 detects the displacement of the acceleration measured by the acceleration sensor 201 after the holding method detection unit 206 detects how the user holds the housing 100-K of the mobile terminal device. It is determined whether or not the absolute value is within a range of 0.5 G to 1.0 G in any of the ± X direction, the ± Y direction, and the ± Z direction. Here, the range of 0.5G to 1.0G corresponds to the detection threshold described with reference to FIG.

  As a result of the determination in step S111, the absolute value of the acceleration displacement measured by the acceleration sensor 201 is outside the range of 0.5G to 1.0G in any of the ± X direction, ± Y direction, and ± Z direction. In some cases (S111 / NO), the absolute value of the displacement of the acceleration measured by the acceleration sensor 201 is 0.5G to 1.0G in any of the ± X, ± Y, and ± Z directions. It waits in step S111 until it becomes in the range.

On the other hand, as a result of the determination in step S111, the absolute value of the displacement of the acceleration measured by the acceleration sensor 201 is in the range of 0.5G to 1.0G in any of the ± X direction, ± Y direction, and ± Z direction. If it is within (S111 / YES), the process proceeds to step S112.
In step S112, the swing direction detection unit 207 determines the direction in which the absolute value of the acceleration displacement measured by the acceleration sensor 201 is in the range of 0.5G to 1.0G. It is detected as the swing direction that is the direction in which the body 100-K is swung.

  Subsequently, in step S113, the number acquisition unit 208 sets the combination in step S101 based on the combination of the holding method detected by the holding method detection unit 206 and the swing direction detected by the swing direction detection unit 207. Get the number that was assigned. For example, the number of the association pattern 1 related to the first table 2031 shown in FIG. 4 is set in step S 101, the holding method detected by the holding method detection unit 206 is “sideways”, and the swing direction detection unit 207 detects it. When the assigned swing direction is “+ X direction”, the number acquisition unit 208 acquires the number “1”.

  Subsequently, in step S114, the authentication processing unit 209 determines whether or not the currently set time-series input number n is smaller than the total number N of the numbers constituting the password set in step S102.

  If the result of the determination in step S114 is that the currently set time-series input number n is smaller than the total number N of the numbers constituting the password set in step S102 (S114 / YES), the password number input process Is not completed yet, the process proceeds to step S115.

  In step S115, the authentication processing unit 209 changes the time-series input number n by adding 1 to the time-series input number n indicating the input order of the numbers input by the user in time-series. Then, it returns to step S105 and performs the process based on the changed time series input number n. That is, in the process of the flowchart shown in FIG. 8, the processes in steps S105 to S115 are repeated for the total number (N) of the numbers constituting the personal identification number set in step S102.

  Also, as a result of the determination in step S114, if the currently set time-series input number n is not smaller than the total number N of the numbers constituting the password set in step S102 (S114 / NO), the password number Is determined to have been completed, and the process proceeds to step S116.

  When the processing proceeds to step S116, the authentication processing unit 209 determines whether or not the time series number, which is the number acquired in time series in step S113, matches the password read in step S102.

As a result of the determination in step S116, when the time-series number that is the number acquired in time-series in step S113 matches the password read in step S102 (S116 / YES), the process proceeds to step S117.

At this time, the holding method detection unit 206 determines the holding method to be detected according to the association information input from the information input unit 204, and detects the determined holding method.

  Next, a processing procedure of the authentication processing method in the mobile terminal device 100 according to the second embodiment will be described.

  FIG. 11 is a flowchart illustrating an example of a processing procedure of an authentication processing method in the mobile terminal device 100 according to the second embodiment of the present invention. 11 is already stored in the personal identification number storage unit 202, and the combination / number correspondence information storage unit 203 stores the personal identification number shown in FIG. Assume that information on the association pattern related to the second table 2032 is stored.

  First, in step S <b> 201, the number setting unit 205 corresponds to the second table 2032 illustrated in FIG. 10 stored in the combination / number correspondence information storage unit 203 in accordance with the association information input from the information input unit 204.

  Subsequently, in step S <b> 202, the authentication processing unit 209 performs processing for reading the password of the authentication registrant stored in the password storage unit 202. In the description of the flowchart shown in FIG. 11, it is assumed that the personal identification number including the total number of “8”, “1”, “10”, and “5” shown in FIG. 3 is read. Further, the authentication processing unit 209 sets the total number N of the numbers constituting the read password. In this example, since the personal identification number shown in FIG. 3 is composed of “8”, “1”, “10”, and “5”, N = 4 is set.

  Subsequently, in step S203, the authentication processing unit 209 sets 1 to the time series input number n indicating the input order of the numbers input in time series by the user.

  Subsequently, in step S <b> 204, the holding method detection unit 206 determines the holding method to be detected according to the association information input from the information input unit 204. In the present embodiment, the number of holding methods to be detected is “two”, and in the example of this flowchart, the association information of the association pattern “1” illustrated in FIG. 10 is input in step S201. Therefore, in this example, the holding method detection unit 206 determines horizontal holding and vertical holding as the holding method to be detected.

  Subsequently, in step S205, the holding manner detection unit 206 determines whether or not 1G acceleration is measured in the −Z direction by the acceleration sensor 201 as illustrated in FIG.

If 1G acceleration is measured in the −Z direction by the acceleration sensor 201 as a result of the determination in step S205 (S205 / YES), the process proceeds to step S206.
In step S206, the holding method detection unit 206 detects horizontal holding as a method of holding the casing 100-K of the mobile terminal device by the user.

  On the other hand, if 1G acceleration is not measured in the −Z direction by the acceleration sensor 201 as a result of the determination in step S205 (S205 / NO), the process proceeds to step S207.

  In step S207, the holding method detection unit 206 determines whether or not 1G acceleration is measured in the −Y direction by the acceleration sensor 201 as illustrated in FIG. 6B.

If 1G acceleration is measured in the −Y direction by the acceleration sensor 201 as a result of the determination in step S207 (S207 / YES), the process proceeds to step S208.
In step S208, the holding method detection unit 206 detects vertical holding as a method of holding the casing 100-K of the mobile terminal device by the user.

  On the other hand, as a result of the determination in step S207, when 1G acceleration is not measured in the −Y direction by the acceleration sensor 201 (S207 / NO), the process returns to step S205, and the processes after step S205 are performed again.

If the process of step S206 or the process of step S208 is completed, the process proceeds to step S209.
In step S209, the swing direction detection unit 207 detects the displacement of the acceleration measured by the acceleration sensor 201 after the holding method detection unit 206 detects how the user holds the housing 100-K of the mobile terminal device. It is determined whether or not the absolute value is within a range of 0.5 G to 1.0 G in any of the ± X direction, the ± Y direction, and the ± Z direction. Here, the range of 0.5G to 1.0G corresponds to the detection threshold described with reference to FIG.

  As a result of the determination in step S209, the absolute value of the displacement of the acceleration measured by the acceleration sensor 201 is outside the range of 0.5G to 1.0G in any of the ± X direction, ± Y direction, and ± Z direction. In some cases (S209 / NO), the absolute value of the acceleration displacement measured by the acceleration sensor 201 is 0.5G to 1.0G in any of the ± X, ± Y, and ± Z directions. It waits in step S209 until it becomes in the range.

On the other hand, as a result of the determination in step S209, the absolute value of the displacement of the acceleration measured by the acceleration sensor 201 is in the range of 0.5G to 1.0G in any of the ± X direction, ± Y direction, and ± Z direction. If it is within (S209 / YES), the process proceeds to step S210.
In step S210, the swing direction detection unit 207 determines the direction in which the absolute value of the acceleration displacement measured by the acceleration sensor 201 is in the range of 0.5G to 1.0G. It is detected as the swing direction that is the direction in which the body 100-K is swung.

  Subsequently, in step S211, the number acquisition unit 208 sets the combination in step S201 based on the combination of the holding method detected by the holding method detection unit 206 and the swing direction detected by the swing direction detection unit 207. Get the number that was assigned. For example, the number of the association pattern 1 related to the second table 2032 shown in FIG. 10 is set in step S 201, the holding method detected by the holding method detection unit 206 is “sideways”, and the swing direction detection unit 207 detects it. When the assigned swing direction is “+ X direction”, the number acquisition unit 208 acquires the number “1”.

  Subsequently, in step S212, the authentication processing unit 209 determines whether or not the currently set time-series input number n is smaller than the total number N of the numbers constituting the password set in step S202.

  As a result of the determination in step S212, if the currently set time-series input number n is smaller than the total number N of the numbers constituting the password set in step S202 (S212 / YES), the password number input process Is not completed yet, the process proceeds to step S213.

  In step S213, the authentication processing unit 209 changes the time-series input number n by adding 1 to the time-series input number n indicating the input order of the numbers input by the user in time-series. Then, it returns to step S205 and performs the process based on the changed time series input number n. That is, in the process of the flowchart shown in FIG. 11, the processes in steps S205 to S213 are repeated for the total number (N) of the numbers constituting the personal identification number set in step S202.

  Also, as a result of the determination in step S212, if the currently set time-series input number n is not smaller than the total number N of the numbers constituting the password set in step S202 (S212 / NO), the password number Is determined to have been completed, and the process proceeds to step S214.

  In step S214, the authentication processing unit 209 determines whether or not the time series number that is the number acquired in time series in step S211 matches the password read in step S202.

As a result of the determination in step S214, if the time-series number that is the number acquired in time-series in step S211 matches the password read in step S202 (S214 / YES), the process proceeds to step S215.
In step S215, the authentication processing unit 209 performs an authentication OK process for permitting the operation of the information processing unit 211 in the mobile terminal device 100. Thereby, the user can use the mobile terminal device 100.

On the other hand, as a result of the determination in step S214, if the time series number, which is the number acquired in time series in step S211, does not match the password read in step S202 (S214 / NO), the process proceeds to step S216.
In step S216, the authentication processing unit 209 performs an authentication NG process that disallows the operation of the information processing unit 211 in the mobile terminal device 100. Thereby, the user cannot use the mobile terminal device 100.

When the process of step S215 or the process of step S216 is completed, the process proceeds to step S217.
In step S217, the authentication processing unit 209 performs processing for displaying the result of the authentication processing by the user on the display unit 210. As a result, if the authentication is not successful in step S216, the display unit 210 displays that the authentication is NG, and if the authentication is successful in step S215, the display unit 210 indicates that the authentication is OK. Is displayed.

  Through the processes in steps S201 to S217, the authentication processing method in the mobile terminal device 100 according to the second embodiment is completed.

  Further, in the second embodiment, the example of the authentication process using the personal identification number having the total number N of 4 has been described following the example shown in FIG. 3, but in the present invention, the total number N of the numbers is not necessarily limited. For example, even if the total number N of the numbers is an authentication process using a PIN number of 2 or 3, or a PIN number having a total number N of 5 or more is used. Even if the authentication process is performed, the present invention is applicable.

  According to the second embodiment described above, it is possible to easily introduce an authentication processing system and to ensure security.

  In the second embodiment, the user can freely assign a unique number to each combination by inputting association information for associating a unique number with each combination of holding method and swing direction.

Here, it returns to description of FIG. 2 again.
For example, the information input unit 204 inputs association information for associating a unique number with each combination of how to hold the third table 2033 illustrated in FIG. 13 and the swing direction. Specifically, in the present embodiment, the user or the like selects “one” in the number-of-holds selection column 111 shown in FIG. 1 and the third pattern 2033 shown in FIG. When the association pattern number is input and the confirmation button 113 is pressed, the information input unit 204 displays the number of holding methods selected in the holding number selection column 111 shown in FIG. The input association pattern number is input to the number setting unit 205 and the holding method detection unit 206 as association information.

  In the present embodiment, the number setting unit 205 refers to the association pattern information related to the third table 2033 in FIG. 13 stored in the combination / number correspondence information storage unit 203 and is input from the information input unit 204. According to the association information, one of the horizontal holding, the vertical holding and the shaking hand holding of the casing 100-K of the mobile terminal device, and the ± X direction defined in the casing 100-K of the mobile terminal device , Unique numbers are set for a total of six combinations of six swing directions in the ± Y direction and the ± Z direction. For example, when the association information related to the association pattern 1 shown in FIG. 13 is input from the information input unit 204, the number setting unit 205 is held sideways and the swing direction is based on FIG. Number “1” for the combination in the + X direction, number “2” for the combination in which the holding method is horizontally held and the swing direction is −X direction, and the number “3” in the combination in which the holding method is horizontally held and the swing direction is + Y direction , The number is “4” for the combination of the horizontal holding method and the swinging direction of −Y direction, the number “5” for the combination of the horizontal holding method and the swinging direction of + Z direction, and the holding method is horizontal holding and swinging The number “6” is set for the combination in which the direction is the −Z direction.

  The holding method detection unit 206 detects how the user holds the casing 100 -K of the mobile terminal device based on the acceleration measured by the acceleration sensor 201. At this time, the holding method detection unit 206 determines the holding method to be detected according to the association information input from the information input unit 204, and detects the determined holding method.

  Next, a processing procedure of an authentication processing method in the mobile terminal device 100 according to the third embodiment will be described.

  FIG. 14 is a flowchart illustrating an example of a processing procedure of an authentication processing method in the mobile terminal device 100 according to the third embodiment of the present invention. 14 is already stored in the personal identification number storage unit 202, and the combination / number correspondence information storage unit 203 stores the personal identification number shown in FIG. Assume that information on the association pattern related to the third table 2033 is stored.

  First, in step S301, the number setting unit 205 corresponds to the third table 2033 shown in FIG. 13 stored in the combination / number correspondence information storage unit 203 in accordance with the association information input from the information input unit 204. With reference to the attachment pattern information, ± one of the holding method of the portable terminal device casing 100-K, which is one of the horizontal holding method, the vertical holding method and the shaking hand holding method, and the ± A unique number is set for a total of six combinations of six swing directions in the X direction, ± Y direction, and ± Z direction. In the description of the flowchart shown in FIG. 14, the number of holding methods detected from the information input unit 204 is “1”, and the association information of the association pattern “1” is input. Based on the above, the number is “1” for the combination of holding sideways and swinging direction + X direction, the number “2” for the combination of holding sideways and swinging direction −X direction, and holding way sideways In addition, the combination of the swing direction + Y direction is the number “3”, the holding method is the horizontal holding and the swing direction is the number “4”, the combination is the horizontal holding and the swing direction is the + Z direction combination. And number “6” is set to the combination of “5” in the holding direction, horizontal holding and swinging direction in the −Z direction.

  Subsequently, in step S <b> 302, the authentication processing unit 209 performs a process of reading the password of the authentication registrant stored in the password storage unit 202. In the description of the flowchart shown in FIG. 14, it is assumed that the personal identification number including the total number of “1”, “4”, “3”, and “2” shown in FIG. 12 is read. Further, the authentication processing unit 209 sets the total number N of the numbers constituting the read password. In this example, since the personal identification number shown in FIG. 12 is composed of “1”, “4”, “3”, and “2”, N = 4 is set.

  Subsequently, in step S303, the authentication processing unit 209 sets 1 to the time series input number n indicating the input order of the numbers input in time series by the user.

  Subsequently, in step S <b> 304, the holding method detection unit 206 determines the holding method to be detected according to the association information input from the information input unit 204. In the present embodiment, the number of holding methods to be detected is “one”, and in the example of this flowchart, the association information of the association pattern “1” illustrated in FIG. 13 is input in step S301. Therefore, the holding method detection unit 206 determines horizontal holding as a holding method to be detected in this example.

  Subsequently, in step S305, the holding method detection unit 206 determines whether or not 1G acceleration is measured in the −Z direction by the acceleration sensor 201 as illustrated in FIG.

  If 1G acceleration is not measured in the −Z direction by the acceleration sensor 201 as a result of the determination in step S305 (S305 / NO), step 1305 is performed until the 1G acceleration is measured in the −Z direction by the acceleration sensor 201. Wait in S305.

On the other hand, if 1G acceleration is measured in the −Z direction by the acceleration sensor 201 as a result of the determination in step S305 (S305 / YES), the process proceeds to step S306.
In step S306, the holding method detection unit 206 detects horizontal holding as a method of holding the casing 100-K of the mobile terminal device by the user.

  Subsequently, in step S307, the swing direction detection unit 207 detects the displacement of the acceleration measured by the acceleration sensor 201 after the holding detection unit 206 detects how the user holds the casing 100-K of the mobile terminal device. Is determined to be within a range of 0.5G to 1.0G in any of the ± X, ± Y, and ± Z directions. Here, the range of 0.5G to 1.0G corresponds to the detection threshold described with reference to FIG.

  As a result of the determination in step S307, the absolute value of the acceleration displacement measured by the acceleration sensor 201 is outside the range of 0.5G to 1.0G in any of the ± X direction, ± Y direction, and ± Z direction. In some cases (S307 / NO), the absolute value of the displacement of the acceleration measured by the acceleration sensor 201 is 0.5G to 1.0G in any of the ± X, ± Y, and ± Z directions. It waits at step S307 until it becomes in the range.

On the other hand, as a result of the determination in step S307, the absolute value of the acceleration displacement measured by the acceleration sensor 201 is in the range of 0.5G to 1.0G in any of the ± X, ± Y, and ± Z directions. If it is within (S307 / YES), the process proceeds to step S308.
In step S308, the swing direction detection unit 207 determines the direction in which the absolute value of the displacement of the acceleration measured by the acceleration sensor 201 is in the range of 0.5G to 1.0G. It is detected as the swing direction that is the direction in which the body 100-K is swung.

  Subsequently, in step S309, the number acquisition unit 208 sets the combination in step S301 based on the combination of the holding method detected by the holding method detection unit 206 and the swing direction detected by the swing direction detection unit 207. Get the number that was assigned. For example, the number of the association pattern 1 related to the third table 2033 shown in FIG. 13 is set in step S301, the holding method detected by the holding method detection unit 206 is “sideways”, and the swing direction detection unit 207 detects the holding method. When the assigned swing direction is “+ X direction”, the number acquisition unit 208 acquires the number “1”.

  Subsequently, in step S310, the authentication processing unit 209 determines whether or not the currently set time-series input number n is smaller than the total number N of the numbers constituting the password set in step S302.

  As a result of the determination in step S310, if the currently set time-series input number n is smaller than the total number N of the numbers constituting the password set in step S302 (S310 / YES), the password number input process Is not completed yet, the process proceeds to step S311.

  In step S311, the authentication processing unit 209 adds 1 to the time series input number n indicating the input order of the numbers input in time series by the user, and changes the time series input number n. Then, it returns to step S305 and performs the process based on the changed time series input number n. That is, in the process of the flowchart shown in FIG. 14, the processes in steps S305 to S311 are repeatedly performed for the total number (N) of the numbers constituting the password set in step S302.

  If the result of the determination in step S310 is that the currently set time-series input number n is not smaller than the total number N of the numbers constituting the password set in step S302 (S310 / NO), the password number The process proceeds to step S312.

  When the processing proceeds to step S312, the authentication processing unit 209 determines whether or not the time series number that is the number acquired in time series in step S309 matches the password read in step S302.

As a result of the determination in step S312, if the time series number, which is the number acquired in time series in step S309, matches the password read in step S302 (S312 / YES), the process proceeds to step S313.
In step S 313, the authentication processing unit 209 performs an authentication OK process for permitting the operation of the information processing unit 211 in the mobile terminal device 100. Thereby, the user can use the mobile terminal device 100.

On the other hand, as a result of the determination in step S312, if the time series number, which is the number acquired in time series in step S309, does not match the password read in step S302 (S312 / NO), the process proceeds to step S314.
In step S314, the authentication processing unit 209 performs an authentication NG process that disallows the operation of the information processing unit 211 in the mobile terminal device 100. Thereby, the user cannot use the mobile terminal device 100.

When the process of step S313 or the process of step S314 is completed, the process proceeds to step S315.
In step S315, the authentication processing unit 209 performs processing for displaying the result of the authentication processing by the user on the display unit 210. As a result, if the authentication is NG in step S314, the display unit 210 displays the authentication NG, and if the authentication is OK in step S313, the display unit 210 indicates the authentication is OK. Is displayed.

  Through the processes in steps S301 to S315 described above, the authentication processing method in the mobile terminal device 100 according to the third embodiment is completed.

  In the third embodiment, the example of the authentication process using the personal identification number having the total number N of 4 has been described following the example shown in FIG. 12, but in the present invention, the total number N of the numbers is not necessarily limited. For example, even if the total number N of the numbers is an authentication process using a PIN number of 2 or 3, or a PIN number having a total number N of 5 or more is used. Even if the authentication process is performed, the present invention is applicable.

  According to the third embodiment described above, it is possible to easily introduce the authentication processing system and to ensure security.

  In the third embodiment, the user can freely assign a unique number to each combination by inputting association information for associating a unique number with each combination of holding method and swing direction. Therefore, it is possible to perform the original password input setting for the user himself / herself. Thereby, security can be made stronger.
