  When the process proceeds to step S107, the holding method detection unit 206 determines whether or not an acceleration of 1 G has been measured by the acceleration sensor 201 in the -Y direction as shown in FIG. 6B.

If it is determined in step S107 that the acceleration sensor 201 measures an acceleration of 1 G in the -Y direction (S107 / YES), the process proceeds to step S108.
In step S108, the holding method detection unit 206 detects vertical holding as the user holds the housing 100-K of the mobile terminal device.

  On the other hand, as a result of the determination in step S107, when the acceleration sensor 201 does not measure an acceleration of 1 G in the -Y direction (S107 / NO), the process proceeds to step S109.

  When the process proceeds to step S109, the holding manner detection unit 206 determines whether or not the acceleration sensor 201 measures an acceleration of 1 G in the + X direction as shown in FIG. 6C.

If it is determined in step S109 that the acceleration sensor 201 measures an acceleration of 1 G in the + X direction (S109 / YES), the process proceeds to step S110.
When the processing proceeds to step S110, the holding method detection unit 206 detects holding by shaking as the holding method of the housing 100-K of the portable 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.

When 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 how the user holds the housing 100-K of the portable terminal device by the holding direction detection unit 206, and then detects the displacement of the acceleration measured by the acceleration sensor 201. It is determined whether the absolute value is in the range of 0.5 G to 1.0 G in any of the ± X direction, ± Y direction, and ± 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 displacement of the acceleration measured by the acceleration sensor 201 is out of the range of 0.5 G to 1.0 G 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 0.5 G to 1.0 G in any of the ± X direction, ± Y direction, and ± Z direction. 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 0.5 G to 1.0 G in any of ± X direction, ± Y direction and ± Z direction. When it is inside (S111 / YES), it progresses to step S112.
When the process proceeds to step S112, the swing direction detection unit 207 sets the direction in which the absolute value of the displacement of the acceleration measured by the acceleration sensor 201 is in the range of 0.5 G to 1.0 G in such a manner that the user 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 manner detected by the holding manner detection unit 206 and the swing direction detected by the swing direction detection unit 207. Get the number that has been 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.

  In step S116, the authentication processing unit 209 determines whether the time-series number, which is the number acquired in time-sequence in step S113, matches the personal identification number read in step S102.

As a result of the determination in step S116, if the time-series number which is the number acquired in time-sequence in step S113 matches the personal identification number read in step S102 (S116 / YES), the process proceeds to step S117.

Then, in this example, when the user performs the operations shown in FIGS. 9A to 9D, the authentication OK process in step S117 is performed.

On the other hand, as a result of the determination in step S116, if the time-series number which is the number acquired in time-sequence in step S113 does not match the personal identification number read in step S102 (S116 / NO), the process proceeds to step S118.
In step S118, the authentication processing unit 209 performs an authentication NG process in which the operation of the information processing unit 211 in the portable terminal device 100 is not permitted. Thus, the user can not use the mobile terminal device 100.

When the process of step S117 or the process of step S118 is completed, the process proceeds to step S119.
In step S119, the authentication processing unit 209 performs processing for displaying the result of the authentication processing by the user on the display unit 210. Thereby, when it is determined that the authentication is NG in step S118, the display unit 210 displays a message indicating that the authentication is NG, and when it is determined that the authentication is OK in step S117, the display unit 210 indicates that the authentication is OK. Is displayed.

  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 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. Note that the personal identification number shown in FIG. 3 is already stored in the personal identification number storage unit 202 at the start of the process of the flowchart 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. Two ways of holding the case 100-K of the portable terminal device horizontally, vertically and shaking hands with reference to the information of the attachment pattern and ± defined in the case 100-K of the portable terminal device A unique number is set for a total of 12 combinations of the six swing directions of the X direction, ± Y direction, and ± Z direction. In the description of the flowchart shown in FIG. 11, the number of holding methods detected from the information input unit 204 is “2”, 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, Holds vertically and swings in the -X direction The number is “8” for the combination, the number is “9” for the combination in which the holding method is vertically held and the swing direction is + Y direction, the number “10” is the combination in which the holding method is vertically held and the swing direction is −Y direction It is assumed that the number “11” is set to the combination of the vertical holding direction and the swing direction is + Z direction, and the number “12” is set to the combination of the vertical holding direction and the swing direction of −Z direction.

  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 out personal identification number. In this example, since the password shown in FIG. 3 consists of “8”, “1”, “10” and “5”, N = 4 is set.

  Subsequently, in step S203, the authentication processing unit 209 sets 1 in 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 the present 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.

When the acceleration sensor 201 measures an acceleration of 1 G in the −Z direction 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 the holding method of the housing 100-K of the mobile terminal device by the user.

  On the other hand, if it is determined in step S205 that the acceleration sensor 201 does not measure an acceleration of 1 G in the -Z direction (S205 / NO), the process proceeds to step S207.

  When the process proceeds to step S207, the holding method detection unit 206 determines whether or not an acceleration of 1 G has been measured by the acceleration sensor 201 in the -Y direction as shown in FIG. 6B.

As a result of the determination in step S207, when the acceleration sensor 201 measures an acceleration of 1 G in the -Y direction (S207 / YES), the process proceeds to step S208.
In step S208, the holding method detection unit 206 detects vertical holding as the user holds the case 100-K of the portable terminal device.

  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 S 209, after the swing direction detection unit 207 detects how the user holds the housing 100-K of the portable terminal device by the holding direction detection unit 206, the displacement of the acceleration measured by the acceleration sensor 201 is detected. It is determined whether the absolute value is in the range of 0.5 G to 1.0 G in any of the ± X direction, ± Y direction, and ± 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.
When the process proceeds to step S210, the swing direction detection unit 207 determines that the direction in which the absolute value of the displacement of the acceleration measured by the acceleration sensor 201 is within the range of 0.5 G to 1.0 G is the case where the user 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 manner detected by the holding manner detection unit 206 and the swing direction detected by the swing direction detection unit 207. Get the number that has been For example, the number of the association pattern 1 according to the second table 2032 shown in FIG. 10 is set by step S201, and the holding manner detected by the holding manner detection unit 206 is “horizontally held”, and the swing direction detection unit 207 detects 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 the currently set time-series input number n is smaller than the total number N of the numbers constituting the personal identification number 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 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 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 It is determined that the input processing of has been completed, and the process proceeds to step S214.

  In step S214, the authentication processing unit 209 determines whether the time-series number, which is the number acquired in time-series in step S211, matches the personal identification number read in step S202.

If it is determined in step S214 that the time-series number, which is the number acquired in time-sequence in step S211, matches the personal identification number 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-sequence in step S211 does not match the personal identification number 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 in which the operation of the information processing unit 211 in the portable terminal device 100 is not permitted. Thus, the user can not 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. Thereby, when it is determined that the authentication is not successful in step S216, the display unit 210 displays a message indicating that the authentication is not successful, and when it is determined that 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. There is no need to use a password of 4. For example, even if authentication is performed using a password with a total number N of 2 or 3 or a password with a total number N of 5 or more The present invention can be applied even to an embodiment in which the authentication process is performed.

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

  Further, in the second embodiment, by inputting the association information for associating the unique number with each combination of the way of holding and the swing direction in the user, the unique number can be freely assigned for each combination. Since it can set to, it becomes possible for the user himself to set the original password input setting. This can make security more robust.

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

  FIG. 14 is a flowchart showing an example of the processing procedure of the authentication processing method in the mobile terminal device 100 according to the third embodiment of the present invention. Note that the personal identification number shown in FIG. 12 has already been stored in the personal identification number storage unit 202 at the start of the process of the flowchart shown in FIG. 14, and the combination / number correspondence information storage unit 203 has the third number shown in FIG. It is assumed that the information of the association pattern according to the table 2033 of 3 is stored.

  First, in step S301, the number setting unit 205 responds to the third table 2033 shown in FIG. 13 stored in the combination / number correspondence information storage unit 203 according to the association information input from the information input unit 204. By referring to the information on the attachment pattern, one way of holding the case 100-K of the portable terminal device horizontally, vertically or shaking hand, and ± defined in the case 100-K of the portable terminal device Unique numbers are set for a total of six combinations of six directions of X direction, ± Y direction, and ± Z direction. In the description of the flowchart shown in FIG. 14, the association information with the number of ways to be detected detected from the information input unit 204 being “one” and the association pattern “1” is input, and the number setting unit 205 Based on the holding method is horizontal holding and the swinging direction is the combination in the + X direction, the number “1”, the holding method is horizontal holding, and the swinging direction is the combination in the −X direction. And the swing direction is the combination in the + Y direction number "3", the holding method is horizontal holding, and the swing direction is the combination in the -Y direction number "4", the holding method is horizontal holding and the swing direction is + 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 a password having a total number of 4 of “1”, “4”, “3” and “2” shown in FIG. 12 has been read. Further, the authentication processing unit 209 sets the total number N of the numbers constituting the read out personal identification number. 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 ways is “one”, and in the example of this flowchart, the association information of the association pattern “1” shown in FIG. 13 is input in step S301. Therefore, in the present example, the holding method detection unit 206 determines horizontal holding as the holding method to be detected.

  Subsequently, in step S305, the holding method detection unit 206 determines whether or not the acceleration sensor 201 measures an acceleration of 1 G in the −Z direction as shown in FIG. 6A.

  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 detection unit 206 detects horizontal holding as the holding method of the housing 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 0.5 G to 1.0 G corresponds to the detection threshold described with reference to FIG.

  As a result of the determination in step S307, the absolute value of the displacement of the acceleration measured by the acceleration sensor 201 is out of the range of 0.5 G to 1.0 G 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 0.5 G to 1.0 G in any of the ± X direction, ± Y direction, and ± Z direction. 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 displacement of the acceleration measured by the acceleration sensor 201 is in the range of 0.5 G to 1.0 G in any of ± X direction, ± Y direction and ± Z direction. When it is inside (S307 / YES), it progresses to Step S308.
When the process proceeds to step S308, the swing direction detection unit 207 determines that the direction in which the absolute value of the displacement of the acceleration measured by the acceleration sensor 201 is within the range of 0.5 G to 1.0 G is the case where the user 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 association pattern 1 according to the third table 2033 shown in FIG. 13 is set by step S301, and the holding manner detected by the holding manner detection unit 206 is “horizontally held”, and the swing direction detection unit 207 detects If the received 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 yet completed, and 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. Thereafter, the process returns to step S305 to perform processing based on the changed time-series input number n. That is, in the processing of the flowchart shown in FIG. 14, the processing of step S305 to step S311 is repeatedly performed by the total number (N) of the numbers constituting the personal identification number 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 It is determined that the input process of is completed, and the process proceeds to step S312.

  In step S312, the authentication processing unit 209 determines whether the time-series number, which is the number acquired in time-series in step S309, matches the personal identification number read in step S302.

As a result of the determination in step S312, when the time-series number which is the number acquired in time-sequence in step S309 matches the personal identification number 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 personal identification number 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 in which the operation of the information processing unit 211 in the portable terminal device 100 is not permitted. Thus, the user can not 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. Thereby, when it is determined that the authentication is not successful in step S314, the display unit 210 displays a message indicating that the authentication is not successful, and when it is determined that the authentication is successful in step S313, the display unit 210 indicates that 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.

  Further, in the third embodiment, an example of the authentication processing by the PIN number whose total number N of numbers is 4 is described according to the example shown in FIG. 12, but in the present invention, the total number N of numbers is not limited. There is no need to use a password of 4. For example, even if authentication is performed using a password with a total number N of 2 or 3 or a password with a total number N of 5 or more The present invention can be applied even to an embodiment in which the authentication process is performed.

  According to the third embodiment described above, the authentication processing system can be easily introduced, and security can be ensured.

  Further, in the third embodiment, by inputting the association information for associating the unique number with each combination of the user's hand and the swing direction, the unique number can be freely assigned for each combination. Since it can set to, it becomes possible for the user himself to set the original password input setting. This can make security more robust.
