In step S8, when the mobile information terminal 10 is unlocked, the process returns to step S1.

  Next, with reference to FIG. 4, the operation when the identification information of the information medium 50 and the identification information 100 do not match in step S2 will be described. FIG. 4 is a flowchart for explaining this operation.

  Referring to FIG. 4, if the identification information of the information medium 50 and the identification information 100 do not match as a result of the comparison in step S2, the operation control means 21 locks the mobile information terminal 10 (step S9). ).

  By the way, there are cases where the information medium 50 has failed and is not recognized, or the information medium 50 is not attached to the portable information terminal 10. Even in such a case, it is assumed that the identification information of the information medium 50 and the identification information 100 do not match, and the process proceeds to step S9.

  Specifically, the portable information terminal 10 cannot be used unless the user inputs a password preset by a valid user of the portable information terminal 10. A password input screen is displayed on the display unit 70 of the portable information terminal 10. At this time, any screen other than the password input screen may not be displayed.

  In addition, when the password input screen is displayed on the display unit 70, the portable information terminal 10 is in a state of waiting for the password input, and prohibits operations other than the password input.

  After the screen lock of the portable information terminal 10 in step S9, when the user inputs the password, the operation control means 21 determines whether the input password is correct (step S10).

  Specifically, it is determined whether or not the personal identification information 101 set in advance matches the input password.

  The person identification information 101 is set in advance by a legitimate owner and is stored in the storage unit 30.

  In the present embodiment, the personal identification information 101 is a password set in advance, but is biometric information such as the fingerprint or iris of a legitimate owner, or information indicating an ID card held by the legitimate owner. May be.

  For example, if the identification information 101 is fingerprint information of a valid owner, the user's finger is placed on the fingerprint authentication unit of the portable information terminal 10 instead of having the user input a password in step S10. By performing the authentication, the operation control unit 21 may determine whether the user is a valid owner of the portable information terminal 10.

  Further, for example, when the identity identification information 101 is information of an ID card held by a legitimate owner, instead of allowing the user to input a password in step S10, the ID card reader included in the portable information terminal 10 The operation control means 21 may determine whether the user is a legitimate owner of the portable information terminal 10 by performing authentication by holding the ID card held by the user.

  As a result of the correctness determination in step S10, if the password input by the user is correct, the operation control means 21 releases the screen lock (step S11).

  In addition, when authenticating with a user's fingerprint, iris, ID card, etc., when the authentication that the mobile information terminal 10 is a valid owner is performed, the operation control means 21 releases the screen lock. You may decide to do it.

  Specifically, when the screen lock is released, the user can operate the portable information terminal 10.

  Specifically, the portable information terminal 10 is made unusable unless the user inputs the personal identification information 101 set in advance by a legitimate user of the portable information terminal 10. A password input screen is displayed on the display unit 70 of the portable information terminal 10. At this time, any screen other than the password input screen may not be displayed.

  In addition, when the password input screen is displayed on the display unit 70, the portable information terminal 10 is in a state of waiting for the password input, and prohibits operations other than the password input.

  By the way, in this embodiment, if it is determined in step S3 that the portable information terminal 10 is in a position that is out of range, in step S13, the screen of the portable information terminal 10 is unconditionally locked. A standby time is set, and during the predetermined standby time, the radio wave status confirmation unit 24 repeats the process of acquiring information indicating the radio wave status from the communication control unit 40, and the portable information terminal 10 is in the range. If information indicating this is acquired, the process may proceed to step S4 without proceeding to step S13.

  This is because the portable information terminal 10 may be instantaneously out of service and immediately return to the service.

  After the screen lock of the portable information terminal 10 in step S13, when the password is input by the user, the operation control unit 21 determines whether the input password is correct (step S14).

  Specifically, it is determined whether or not the user identification information 101 set in advance matches the input password.

  Note that the preset identification information 101 is set in advance by a legitimate owner and stored in the storage unit 30.

  In this embodiment, the personal identification information 101 is a password set in advance, but biometric information such as a fingerprint or iris of a legitimate owner, or a non-contact type ID card held by the legitimate owner. It may be the information shown.

  For example, when the personal identification information 101 is information on the fingerprint of a valid owner, the user's finger is placed on the fingerprint authentication unit of the portable information terminal 10 instead of having the user input a password in step S14. By performing the authentication, the operation control unit 21 may determine whether the user is a valid owner of the portable information terminal 10.

  Also, for example, when the identity identification information 101 is information of an ID card held by a legitimate owner, instead of allowing the user to input a password in step S14, the ID card reader included in the portable information terminal 10 The operation control means 21 may determine whether the user is a legitimate owner of the portable information terminal 10 by performing authentication by holding the ID card held by the user.

  As a result of the correctness determination in step S14, when the password input by the user is correct, the operation control means 21 releases the screen lock (step S15).

  Specifically, when the screen lock is released, the user can operate the portable information terminal 10.

  In addition, when authenticating with a user's fingerprint, iris, ID card, etc., when the authentication that the mobile information terminal 10 is a valid owner is performed, the operation control means 21 releases the screen lock. You may decide to do it.

  On the other hand, if the password input by the user is incorrect in step S14, the process returns to step S13 (step S14).

  In the case of authenticating with the user's fingerprint, iris, ID card, etc., if authentication that the mobile information terminal 10 is a valid owner is not performed, the process returns to step S13. Also good.

  By the way, in this embodiment, after the screen is locked, the password is authenticated in step S14 and then the screen lock is released in step S15. While the screen is locked, When the radio wave status confirmation unit 24 repeats the process of acquiring information indicating the radio wave status from the communication control unit 40 and acquires information indicating that the portable information terminal 10 is in a range, the right owner The operation control means 21 may release the screen lock and proceed to the process of step S16 without performing the authentication of “no”.
