Embodiments of the password setting tool of the present invention will be described below. The embodiment of the present invention shows the most preferable mode of the present invention, and the present invention is not limited to this.
[First Embodiment]

  FIG. 1 is a plan view of the password setting tool of the first embodiment. The password setting tool 1 according to the first embodiment is composed of a rectangular card, and the rectangular card is made of paper, resin, or the like. The password setting tool 1 has a number from 0 to 9 on any horizontal side and a number from 0 to 9 on any vertical side. In this embodiment, the upper horizontal side has a number from 0 to 9, and the left vertical side has a number from 0 to 9.

  Either the number from 0 to 9 on the horizontal side or the number from 0 to 9 on the vertical side is set as the main number, and the other number from 0 to 9 as the main number is set as the sub number. In this embodiment, The number 0-9 on the upper horizontal side is the main number 10, and the number 0-9 on the left vertical side is the sub-number 20.

  And the password setting tool 1 makes the character string containing 0-9 of any combination of the number of 0-9 and a suitable English character, and each row | line | column and each column of the matrix corresponding to the main number 10 and the subordinate number 20 2 has a random number table 30 in which character strings including 0 to 9 are arranged in a random manner. An entry field 40 is provided below the random number table 30 for entering information on the newly set password.

  In the password setting tool 1, a sub-number is determined based on information to be processed by a password. For example, if the first digit of the bank account × ○ △ □ is “1”, the subordinate number is set to “1”, and a character string including 0 to 9 in the random number table 30 is determined as a selection target by the subordinate number 20 determined and set in advance. The main number 10 is determined based on the information of the password being used, for example, “1234”, and a character string including 0 to 9 in the random number table 30 is determined as a selection target based on the determined main number 10.

  Then, it is possible to set a new password by the intersection of the character string including 0 to 9 to be selected by the sub number 20 and the character string including 0 to 9 to be selected by the main number 10. That is, if the selection target by the sub number 20 is “1” and the selection target by the main number 10 is “1234”, a new password is set to “8903”. In this embodiment, only a numerical value of a character string including 0 to 9 is taken out and a new password is set as “8903”, and account information related to this new password is entered in the entry field 40, It is possible to associate that the secondary number is “1”.

  In this way, a new password is obtained from the password set in advance by the intersection of the character string including 0 to 9 to be selected by sub number 20 and the character string including 0 to 9 to be selected by main number 10. It is possible to set. The new password may be numbers only, letters only, or a combination of numbers and letters.

  With this new password, the password can not be easily understood from the date of birth, telephone number, address, etc., and it is possible to prevent a cash card, a credit card, etc. from being illegally used due to loss or theft.

  Next, the first embodiment will be described based on the flowchart of the password management method of FIG.

  In the password management, first, each of 0 to 9 and an appropriate combination of English characters are created, and a matrix in which character strings including 0 to 9 are randomly arranged in each row and column of a 10 × 10 matrix. A random number table 10 is created (S11).

  Next, the arrangement of the main numbers is selected (S12). For example, if the vertical arrangement is selected, the vertical arrangement of the matrix is selected as the main number, and the horizontal arrangement is selected as the sub-number (S13). Is selected as the main number and the vertical alignment is selected as the sub-number (S14).

  A secondary number 10 is determined based on information such as an account number (S15). Then, each digit of the preset password is processed from the first digit (S16). Based on the numerical value of the nth digit of the preset password, the main number 10 is determined (S17).

  In the random number table 10 of the matrix, the character at the intersection of the sequence of the main number 10 and the sequence of the sub-number 20 is the nth of the new password obtained (S18). In this way, processing is performed up to the last digit of the preset password (S19, S20), and the new password obtained is deleted if the alphabet is unnecessary (S21).

  Next, sub-number determination according to another embodiment will be described. FIG. 3 is a flowchart of the secondary number determination method. In the case of a new password setting according to FIG. 2 (S31), the first digit or the last digit of a bank account number or a fixed digit is used as a secondary number (S32). If the password is not newly set according to FIG. 2 (S31), it is determined whether or not the password is updated (S33). If the password is updated, an arbitrary number is added to the end of the bank account number or the like. A note is made in the entry field 40 (S34).

  In the case of this password update, or if the password is not updated in step S33, the last digit of the answer obtained by adding or multiplying the X and Y digits from the end of the account number or the like is used as the sub number. . Or, similarly, the X digit from the end is regarded as the main number, and the number of the character string intersecting each other with the Y digit as the sub number is set as the sub number (S35).

  Next, main number determination according to another embodiment will be described. FIG. 4 is a flowchart of the main number determination method. In the case of a new password setting according to FIG. 2 (S41), the numerical value of the nth digit of the usual password is directly used as the main number (S42).

  When the password is not newly set according to FIG. 2, the numerical value of the n-th digit of the password set in advance is set as the main number, and the number of the character string that intersects the previously determined sub-number sequence is set as the main number. Alternatively, the numerical value of the n-th digit of the password set in advance is set as the main number, and the number of the character string that intersects the fixed sub-number sequence is set as the main number (S42).

As described above, although the secondary number determination and the main number determination are different in the password management method of FIG.
