Concrete, password authentication device can realize with reference to prior art the collection of fingerprint, repeats no more herein.
102, according to the fingerprint-character correspondence relationship information prestored, the character corresponding with the current fingerprint collected is searched;
In the embodiment of the present invention, user can preset fingerprint-character correspondence relationship information by password authentication device, and this fingerprint-character correspondence relationship information is stored in the miscellaneous equipment that local or this password authentication device of password authentication device can access.
In the embodiment of the present invention, mapping relations one by one set up in the fingerprint that ten, the left and right of oneself can be pointed by password authentication device by user in advance and any ten characters.
Concrete, the process that password authentication device sets up fingerprint-character correspondence relationship information includes but not limited to the following two kinds mode:
1, the character that password authentication device display is conventional, user can first therefrom select a character (for ease of subsequent descriptions, this character is described as character A1), then input wishes that the fingerprint corresponding with character A1 is (for ease of subsequent descriptions, this fingerprint is described as fingerprint B1), when after password authentication device successful acquisition to fingerprint B1, set up the corresponding relation of fingerprint B1 and character A1, and the corresponding relation of fingerprint B1 and character A1 is added in fingerprint-character correspondence relationship information, user can continue to select another character (for ease of subsequent descriptions afterwards, this character is described as character A2), then input wishes that the fingerprint corresponding with character A2 is (for ease of subsequent descriptions, this fingerprint is described as fingerprint B2), when after password authentication device successful acquisition to fingerprint B2, set up the corresponding relation of fingerprint B2 and character A2, and the corresponding relation of fingerprint B2 and character A2 is added on fingerprint-character correspondence relationship information, by that analogy.Certainly, user also can revise the corresponding relation of fingerprint and the character set up, namely, when the character that password authentication device detects current selection or the fingerprint that collects have existed in fingerprint-character correspondence relationship information, this fingerprint-character corresponding relation set up is updated to fingerprint-character correspondence relationship information, to replace the information relevant with this character or this fingerprint that fingerprint-character correspondence relationship information Central Plains pre-exists.Illustrate, when the corresponding relation of fingerprint B1 and character A1 has been added in fingerprint-character correspondence relationship information, user can reselect character A1, then input wishes that the new fingerprint corresponding with character A1 is (for ease of subsequent descriptions, this fingerprint is described as fingerprint B3), when after password authentication device successful acquisition to fingerprint B3, set up the corresponding relation of fingerprint B3 and character A1, password authentication device detects that character A1 has existed in fingerprint-character correspondence relationship information simultaneously, then the corresponding relation of the fingerprint B3 that this set up of password authentication device and character A1 is updated in fingerprint-character correspondence relationship information, to replace the corresponding relation of fingerprint B1 that fingerprint-character correspondence relationship information Central Plains pre-exists and character A1 (namely, in fingerprint-character correspondence relationship information, the corresponding relation of the fingerprint B1 originally existed and character A1 is deleted).Or, when the character that password authentication device detects current selection or the fingerprint that collects have existed in fingerprint-character correspondence relationship information, the character of the current selection of reminding user or the fingerprint collected have existed in fingerprint-character correspondence relationship information, so that user selects whether to replace the information relevant with this character or this fingerprint that fingerprint-character correspondence relationship information Central Plains pre-exists voluntarily.
2, the character that password authentication device display is conventional, user inputs fingerprint (for ease of subsequent descriptions, this fingerprint is described as fingerprint B1), when after password authentication device successful acquisition to fingerprint B1, prompting user selects a character from the character of display, when user selects a character (for ease of subsequent descriptions, this character is described as character A1) after, password authentication device sets up the corresponding relation of fingerprint B1 and character A1, and the corresponding relation of fingerprint B1 and character A1 is added in fingerprint-character correspondence relationship information, user can continue to input another fingerprint (for ease of subsequent descriptions afterwards, this fingerprint is described as fingerprint B2), when after password authentication device successful acquisition to fingerprint B2, password authentication device prompting user selects another character, when user selects a character (for ease of subsequent descriptions, this character is described as character A2) after, password authentication device sets up the corresponding relation of fingerprint B2 and character A2, and the corresponding relation of fingerprint B2 and character A2 is added on fingerprint-character correspondence relationship information, by that analogy.Certainly, user also can revise the corresponding relation of fingerprint and the character set up, namely, when the character that password authentication device detects current selection or the fingerprint that collects have existed in fingerprint-character correspondence relationship information, this fingerprint-character corresponding relation set up is updated to fingerprint-character correspondence relationship information, to replace the information relevant with this character or this fingerprint that fingerprint-character correspondence relationship information Central Plains pre-exists.Illustrate, when the corresponding relation of fingerprint B1 and character A1 has been added in fingerprint-character correspondence relationship information, user can re-enter fingerprint B1, then select to wish that the new character corresponding with fingerprint B1 is (for ease of subsequent descriptions, this fingerprint is described as fingerprint A3), password authentication device sets up the corresponding relation of fingerprint B1 and character A3, password authentication device detects that fingerprint B1 has existed in fingerprint-character correspondence relationship information simultaneously, then the corresponding relation of the fingerprint B1 that this set up of password authentication device and character A3 is updated in fingerprint-character correspondence relationship information, to replace the corresponding relation of fingerprint B1 that fingerprint-character correspondence relationship information Central Plains pre-exists and character A1 (namely, in fingerprint-character correspondence relationship information, the corresponding relation of the fingerprint B1 originally existed and character A1 is deleted).Or, when the character that password authentication device detects current selection or the fingerprint that collects have existed in fingerprint-character correspondence relationship information, the character of the current selection of reminding user or the fingerprint collected have existed in fingerprint-character correspondence relationship information, so that user selects whether to replace the information relevant with this character or this fingerprint that fingerprint-character correspondence relationship information Central Plains pre-exists voluntarily.
In a kind of concrete application scenarios, user can set arbitrarily ten finger prints and 0 ~ 90 numeral about oneself and set up mapping relations one by one.
In a step 102, password authentication device, according to the fingerprint prestored-character correspondence relationship information, searches the character corresponding with the fingerprint that step 101 collects.
