Device, program and method for calculating a number of days a password is used
An information processing device includes a display. A password input screen for a user to input a password is displayed on the display. When the password is input on the password input screen, the useful number-of-days of the input password is calculated according to a predetermined calculation condition. When the useful number-of-days of the password is calculated, a confirmation screen for allowing the user to confirm the useful number-of-days of the calculated password is displayed on the display.
1. A computing device comprising:
a first processor;
a first non-transitory machine-readable memory storing instructions that, when executed by
the processor, cause the computing device to:
receive an operation of a user;
calculate a useful number-of-days of a password, which is input by the operation of the user received by the computing device, according to a predetermined calculation condition including a search speed that is calculated based on another factor other than the password itself; and
a display that presents the useful number-of-days calculated by the computing device to the user.
2. The computing device according to claim 1 , further causing the computer device to:
set a calculation condition according to the operation of the user received by the computing device.
3. An information processing device comprising:
the computing device according to claim 1 ; and
a register that registers a password input by computing device.
4. The information processing device according to claim 3 , further comprising:
a second processor;
a second non-transitory machine-readable memory storing instructions that, when executed by the second processor, cause the information processing device to:
set a lower limit number-of-days of the useful number-of-days; and
determine whether or not the useful number-of-days calculated by the computing device reaches the lower limit number-of-days,
wherein the register registers a password in a case where it is determined that the useful number-of-days reaches the lower limit number-of-days.
5. The information processing device according to claim 3 ,
wherein the register sets an update date of expiration of time limit of the registered password in accordance with the useful number-of-days calculated by the computing device.
6. The information processing device according to claim 3 , further comprising:
a data storage that stores data associated with the password,
wherein the register sets a storage time limit of the data according to the useful number-of-days calculated by the computing device.
7. A non-transitory computer readable storage medium storing a control program of a computing device, the control program executed by a computer of the
computing device that receives an operation of a user and causing the computer of the computing device to:
calculate a useful number-of-days of a password, which is input by the operation of the user, received by the computer, according to a predetermined calculation condition including a search speed that is calculated based on another factor other than the password itself; and
a display that presents the useful number-of-days calculated by the computer to the user.
8. A control method of a computing device, comprising:
by a computer of the computing device that receives an operation of a user,
(a) calculating a useful number-of-days of a password, which is input by the operation of the user, received by the computer, according to a predetermined calculation condition including a search speed that is calculated based on another factor other than the password itself; and
(b) presenting the useful number-of-days calculated in the calculating (a) to the user.
