Embodiment
For enabling above-mentioned purpose of the present invention, feature and advantage become apparent more, are described in further detail the embodiment of the present invention below in conjunction with the drawings and specific embodiments.
Cipher authentication method of the present invention, for there is password in prior art by eye recognition, and cut can be left on the touchscreen, there is the risk that password is revealed, propose when being unlocked by password at every turn, to several identification informations of standard cipher be included (as numeral, character or picture) stochastic generation is on the touchscreen, user is by the identification information input password of the upper relevant position of point touching screen, realize the certification of password, because several identification informations that each touch-screen generates can be different, the position of each identification information also can be different, therefore the position clicked when user inputs password is random, other people are not easy to identify, reduce the possibility that password is revealed, thus improve the fail safe of cipher authentication.
Based on above-mentioned thought, shown in Figure 1, cipher authentication method of the present invention comprises the following steps:
Step 101: receive the standard cipher that user presets, standard cipher is made up of the characteristic value of several identification informations.
User presets the standard cipher for unlocking, the figure place of standard cipher can by user's sets itself, each of standard cipher all can be represented by an identification information, this identification information can be numeral, character or picture, each identification information can correspond to a characteristic value, for identification information be numeral or character time, its characteristic value can be this identification information itself, the characteristic value of such as identification information " a " can be " a ", the characteristic value of such as identification information " 1 " can be " 1 ", and identification information is when being picture, its characteristic value can be the sequence number of setting, namely standard cipher formally can by set of number, the combination of character or picture is formed, the so final standard cipher preserved is several identification information characteristic of correspondence values composition.
Can set up encrypted message storehouse in advance, encrypted message storehouse can comprise password default information bank and/or User Defined encrypted message storehouse; Password default information bank comprises several identification informations that system generates; User Defined encrypted message storehouse comprises several identification informations that user adds; For each identification information in encrypted message storehouse distributes characteristic of correspondence value; Identification information is numeral, character or picture.
That is, encrypted message storehouse comprises several can as the identification information of password symbol, user can by the mode in self-defined encrypted message storehouse, picture or pattern is added voluntarily in encrypted message storehouse, the travelling picture etc. of such as user, make user can use self-defining identification information when established standards password, make this standard cipher be not easy to pass into silence.Each identification information in encrypted message storehouse needs to distribute characteristic of correspondence value, such as, be different picture distributing serial numbers.
Step 102: when receiving unlock command, on the touchscreen several identification informations of stochastic generation, and the record positional information of identification information on the touchscreen and the corresponding relation of the characteristic value of this identification information.
Unlock command can be pressed by user and separate locking key triggering, and also can need trigger in the application unlocked at other, when receiving unlock command, several identification informations of stochastic generation, shown in Figure 2 on the touchscreen.Several identification informations of stochastic generation need each identification information of comprising in standard cipher on the touchscreen, on touch-screen, the quantity of identification information should be more than or equal to the quantity of standard cipher identification information, the quantity of the identification information that touch-screen occurs also can by user's sets itself, and what user also can set the identification information of stochastic generation on the touchscreen carrys out source range.The identification information quantity that such as user sets stochastic generation on touch-screen is 8,100 identification informations are had in encrypted message storehouse, several identification informations that user can set stochastic generation are on the touchscreen to be derived from certain subset in encrypted message storehouse or some subset (as the identification information of 15 in encrypted message storehouse), then finally generate unlock interface time can from 15 identification informations of this encrypted message storehouse subset Stochastic choice 8 stochastic generation optional positions on the touchscreen, with adding users use flexibility.
Further, several identification informations (numeral can be selected from encrypted message storehouse, character or picture) be randomly distributed on touch-screen, comprising the identification information of standard cipher, the corresponding relation of each position and identification information is all random, therefore the corresponding relation of the positional information of the identification information recorded on the touchscreen and the characteristic value of this identification information is needed, so that the positional information clicked by user in the process of subsequent check obtains the identification information of its correspondence, thus obtain the characteristic value of this identification information, contrast eventually through characteristic value judges whether cipher authentication passes through.
Concrete, the one-to-one relationship of the positional information of each identification information on the touchscreen and the characteristic value of this identification information can be recorded; Also can the one-to-one relationship of the positional information of identification information only in record standard password and the characteristic value of this identification information, record the positional information of other identification informations on the touchscreen and the corresponding relation of miscue characteristic value, the positional information of such as other identification informations is all corresponding with miscue characteristic value Err, then in subsequent cryptographic verification process, if the identification information in the non-standard password that user clicks, what then obtain is miscue characteristic value Err, does not need the real characteristic of correspondence value of identification information obtaining this mistake.
Step 103: obtain the positional information that user inputs on the touchscreen, obtains the characteristic value of several corresponding identification informations according to several positional informations obtained, the unlocking pin of the characteristic value composition user input of several identification informations of acquisition.
The positional information clicked on the touchscreen by user can obtain the characteristic value of identification information corresponding to this positional information, such as identification information " picture 1 " positional information is on the touchscreen coordinate (1,1), identification information " picture 1 " characteristic of correspondence value is " 001 ", then user's click coordinate (1,1) position can obtain identification information " picture 1 " characteristic of correspondence value " 001 ".
Concrete, the positional information of the identification information that user clicks on the touchscreen successively can be obtained; Or, obtain user's line positional information of identification information of streaking on the touchscreen; Or, obtain the positional information that user drags to the identification information of appointed area on the touchscreen.
Several positional informations clicked during by obtaining user and inputting password on the touchscreen, several characteristic values can be obtained, the stack features value obtained when then can input password by user and a stack features value of standard cipher contrast, and judge that whether the unlocking pin that user inputs is correct.
Step 104: judge that whether unlocking pin is identical with standard cipher, if so, then unlocks successfully, if not, then unlocks failure.
Namely the unlocking pin and standard cipher that input generation from touch-screen are compared under equipment lock-out state, then unlock when comparative result is consistent state.If unlock unsuccessfully, can also step 102 be returned to, again several identification informations of stochastic generation on the touchscreen, again carry out cipher authentication.
In addition, cipher authentication method of the present invention can also comprise:
Preset Password Input region, and record the position range in Password Input region;
After the positional information that acquisition user inputs on the touchscreen, judge whether positional information that user inputs on the touchscreen belongs to the position range in Password Input region, if, continue to perform step obtains several corresponding identification informations characteristic value and subsequent step thereof according to several positional informations obtained, if not, then failure is unlocked.
Preset Password Input region, and record the position range in Password Input region, several identification informations of each identification information comprised in standard cipher are generated in setting code input area, also several identification informations comprising part or all of identification information in standard cipher can be generated in other positions of touch-screen, then when user inputs password, because Password Input region presets, do not show, the identification information only inputted in Password Input region can form unlocking pin.Like this, even if the password of user is revealed, also need in the Password Input region of presetting, input password and can realize unlocking, and Password Input region does not show, the password in other regions is actual in distracter, further ensures the fail safe of user.Shown in Figure 3, provide a kind of specific embodiment of cipher authentication method, user can carry out cipher authentication by variable path.
Step 201: set up encrypted message storehouse, encrypted message storehouse can comprise password default information bank and/or User Defined encrypted message storehouse.Namely include several can accord with (i.e. password each) identification information as password in encrypted message storehouse, identification information can be numeral, character or picture.For identification information assigned characteristics value, this characteristic value can be identification information itself.
Step 202: receive the standard cipher that user presets.Specify several identification informations by user and determine that order realizes.Standard cipher can be the characteristic value of one group of identification information, and when only comprising numeral or character in password, because its characteristic value when numeral or character are identification information can be itself, then in fact standard cipher is equal to and is made up of one group of identification information.
Step 203: stochastic generation unlock interface.When needs unlock, several identification informations (numeral, character or picture) chosen in encrypted message storehouse are randomly distributed on touch-screen, and the corresponding relation of each identification information and positional information is random.Generate complete, then identification information and positional information establish and determine relation, therefore need the corresponding relation of the positional information of the identification information recorded on the touchscreen and the characteristic value of this identification information.
It should be noted that, if take user to streak the mode obtaining positional information at line on the touchscreen, namely the mode being similar to path authentication carries out cipher authentication, then the contact (positional information) of any three identification informations can not point-blank occur.Such as, if three identification informations on the same line, user wishes the identification information inputting straight line two ends, takes the mode that line streaks, and there is the possibility of simultaneously having streaked three identification informations, and wishes that the identification information inputted is different from user.Therefore, in order to avoid the possibility of user misoperation, the contact of any three identification informations can not point-blank occur.
Step 204: the unlocking pin receiving user's input, namely user's line positional information of identification information of streaking on the touchscreen is obtained, the characteristic value of several corresponding identification informations is obtained, the unlocking pin of the characteristic value composition user input of several identification informations of acquisition according to several positional informations of user's input.
Step 205: judge that whether unlocking pin is identical with standard cipher, if so, then unlocks successfully, if not, then unlocks failure, return step 203.
