Password create-rule of the present invention has a variety of implementations, and the present invention does not limit this, enumerates several examples of application below and further describes the present invention:
Application example one:
The user imports correct super code, and the password create-rule is set, and this password create-rule is described below:
The user imports a string 4 to 8 initial password earlier, and for example " 012456 ", terminal writes this initial password in the nonvolatile storage on the terminal (after the terminal power down on this memory information still can preserve).Terminal is according to the 2nd and the 3rd bit digital of minute value modification initial password of current time, as current proper password.For example, the current time is 8: 08, and then current proper password is " 008456 "; Current time is 18: 23, and then current proper password is " 023456 ".The user is desire visit protected function or file in 12: 20, and terminal interface ejects a password input frame, and the prompting user inputs password, and the user must import " 020456 " could visit this function or file, otherwise prompt cipher mistake and returning.
Application example two
The user imports correct super code, and input n group initial password, and the life cycle of every group of password and the use order of n group password are set, and the password create-rule of setting is for using a group in the n group password successively by the order that is provided with.
Specifically describe as follows:
The user imports n group initial password earlier, and for example, first group of password is " 34567 ", and second group of password is " 789012 ", and the 3rd group of password is " 123789 ", and terminal writes these several groups of initial passwords in the nonvolatile storage on the terminal.The rule that terminal was used one day according to one group of password is changing one group of password wherein as the proper password on the same day, and the cipher code set sequence number of nearest one day date with correspondence write in the nonvolatile storage.For example, the user is on 01 01st, 2009 when this password create-rule is set, and the password of this day should be " 34567 " so, and terminal writes this date and cipher code set sequence number 1 in the nonvolatile storage; In on 01 02nd, 2009, date (on 01 01st, 2009) in terminal contrast current date and the nonvolatile storage, increased progressively one day, then the cipher code set sequence number also will increase progressively 1 and become 2, promptly on 01 02nd, 2009 this day, password is " 789012 ", and terminal writes this date and cipher code set sequence number 2 in the nonvolatile storage; In on 01 03rd, 2009, date (on 01 02nd, 2009) in terminal contrast current date and the nonvolatile storage, increased progressively one day, then the cipher code set sequence number also will increase progressively 1 and become 3, promptly on 01 03rd, 2009 this day, password is " 123789 ", and terminal writes this date and cipher code set sequence number 3 in the nonvolatile storage; In on 01 04th, 2009, date (on 01 03rd, 2009) in terminal contrast current date and the nonvolatile storage, increased progressively one day, then the cipher code set sequence number also will increase progressively 1 and become 4, find that sequence number 4 has surpassed the cipher code set number 3 that the user sets, then bring into use from first group of password again, promptly on 01 04th, 2009 this day, password is " 34567 ", and terminal writes this date and cipher code set sequence number 1 in the nonvolatile storage.On 01 04th, 2009 this day; user's desire visit protected function or file, terminal interface ejects a password input frame, and the prompting user inputs password; the user must import " 34567 " could visit this function or file, otherwise prompt cipher mistake and returning.If the situation that the date falls back is arranged, such as user's date of being set to fall back on date manually, then do the calculating of successively decreasing accordingly, especially,, then bring into use from last group password again when the cipher code set sequence number is decremented to when being equal to or less than 0.
