Abstract
At present, many fields which need to enter passwords to authenticate the correct identification, but most adopts a password of regular length, so the password is easy to peep during entering, causing password exposure. A password authentification method can be applied to the fields which need to enter password to authenticate the identification of a user. The method uses a reserved long password, and several reserved password characters must be different, short passwords are stochastically generated at different times, and the group of password characters are promoted to be corresponding to the positions in the long password characters to require the user to enter. The password characters stochastically generated every two adjacent times must be different, so the probability that the password is peeped, causing password exposure, is greatly lowered.
Description
Technical field: this method is applicable to the occasion that requires password authentification, such as bank POS T machine etc.
Background technology: utilize program to calculate, in the longer password of reserving, randomly draw several characters, be combined into random cipher.Make that each proper password of input that requires is all inequality, prevent the password leakage.
Summary of the invention: reserve the password of a longer figure place, from the password of this longer figure place, specify the password of several locational characters at random as each identity verification.Such as the password of reserving one 10 figure place, the character of specifying the 3rd, the 8th, the 5th, the 6th at random is as the password of one-time authentication identity.The character of specifying the 2nd, the 5th, the 7th, the 9th when need password authentification next time more at random is as the password of next identity verification, just specify the code characters of other locational characters at random again if the code characters of the code characters of the 2nd, the 5th, the 7th, the 9th generation of current appointment and the 3rd, the 8th, the 5th, the 6th generation of appointment last time is identical, till inequality with the code characters of last time as this identity verification.Then this random cipher corresponding to the position indicating importer in the reserving cipher character, require correctly input.Some positions character inequality will be arranged in the code characters that requires to reserve.
Embodiment: when requiring to import password authentification, from the code characters of reserving, specify several locational characters by computer program at random as password, and judge whether identical with the password that required last time to import, if identically promptly produce one group of password once more at random, and judge again, promptly produce password cycle criterion like this more at random as also identical, until produce with the password that required input last time inequality till.Point out then this group password of importer is corresponding to which position in the reserving cipher character, require the importer to import these locational code characters.Subsequently the character of importer's input and the code characters of program generation are compared, if both unanimities promptly are verified as proper password by authentication, otherwise give No. 2 reader meetings again, use up as 3 chances, import still inconsistently, promptly be verified as bad password refusal and pass through.This kind method makes the proper password of importing when inferior requirement once not repeat with preceding, even make that intentionally the people of snooping password sees that certain proper password still can't use this password.
Claims (1)
1. this method is applied to require to input the occasion (such as the post of bank machine etc.) of password, feature is: reserving the multidigit password and multidigit is arranged is character inequality, when requiring to input password and identity verification, calculate by program, in the middle of this group password, randomly draw the password of several locational characters as this time identity verification.Each proper password that requires input can not be with last time password be identical, if identical then calculate by program, extracted one group again as stated above.Ask for protection method of password authentication with this technical characterictic.
