Embodiment 1

According to the embodiment of the present invention, provide a kind of unlock method for terminal device.Alternatively, in the present embodiment, the above-mentioned unlock method for terminal device can be applied to mobile phone as shown in Figure 4.Certainly, the method that the embodiment of the present invention provides can also be used in the unshowned panel computer of Fig. 4, PC.

Embodiments provide a kind of unlock method for terminal device.Fig. 5 is the process flow diagram of the unlock method of terminal device according to the embodiment of the present invention.As shown in the figure, the unlock method of this terminal device comprises the steps:

Step S502, under terminal device is in screen lock state, show the first character and the input frame of stochastic generation, wherein, the first character comprises one or more character.

Terminal device is in screen lock state, and can be that the intelligent terminals such as mobile phone, panel computer, PC are in lock state of screen, screen display be black, or pattern of only having powerful connections but cannot operate terminal, and namely screen is in the lock state.Such as, panel computer needs to light screen after dormancy and unlock screen just can wake panel computer up to carry out the operation to panel computer, after the physical button or virtual key of touch screen or touch terminal equipment, the screen of panel computer is lighted, but the now inputting interface of screen display unlocking pin, shown in traditional unlocking pin inputting interface Fig. 1 to Fig. 3, also can the inputting interface of Explicit solutions lock cipher after waking screen up in the present embodiment, but the first character of inputting interface display stochastic generation of the present invention and input frame, as shown in Figure 6.

When terminal device is in screen lock state, also comprises the application program that terminal device is installed and be in screen lock state.Such as, confidential folder mobile phone installed.The file stored in file is classified document, if need to check that these files first will input password, so, also can show the inputting interface of unlocking pin as shown in Figure 6 when opening this application program.

The inputting interface of the unlocking pin shown in Fig. 6 not only shows the input frame of password, also shows the first character of stochastic generation.First character of stochastic generation can comprise a character or multiple character.First character of stochastic generation can be letter, also can be numeral.If what generate is letter, the first character so generated can comprise multiple letter, and owing to being the letter of stochastic generation, the letter so generated can have the letter of repetition.Similarly, the numeral of stochastic generation also can comprise multiple numeral, certainly, also can have the numeral of repetition.

Such as, the first character of generation is 1,23,456, and wherein, 1,23 and 456 are a character, and these three characters form the first character.Each character comprises again one or more data bit, and " 2 " and " 3 " as character 23 are respectively a data bit.

Step S504, receives the second character of input by input frame.

Second character is the character that user is inputted by input frame, i.e. the unlocking pin of user's input.Second character is the transformation result that user obtains according to the conversion formula pre-set.

Step S506, compares the second character the three-character doctrine that the first character is converted to using the conversion formula pre-set.

Step S508, if the second character is consistent with three-character doctrine, is then transformed into released state by terminal device from screen lock state.

After stochastic generation first character, according to the conversion formula pre-set, the first character is changed, obtain three-character doctrine.The unlocking pin that three-character doctrine and terminal device calculate according to conversion formula, therefore, when the second character of user's input is identical with the three-character doctrine that terminal device calculates, determines that the unlocking pin that user inputs is correct.

The conversion formula pre-set can be arranged by user, therefore, when user sees the character of stochastic generation, can calculate the second character according to conversion formula.Terminal device also calculates three-character doctrine according to the conversion formula preset.After stochastic generation first character, terminal device and user calculate unlocking pin according to the conversion formula pre-set respectively, the formula of terminal device and user's foundation is identical, so, should be identical according to the result of same transitions formulae discovery, that is according to show first character calculate three-character doctrine and the second character should be identical, terminal device so just can be made to be converted to released state from screen lock state.

All need when unlocking to regenerate the first new character at every turn, because the first character is stochastic generation, each the first character generated is all different, therefore, also be dynamic according to the unlocking pin that the first character and conversion formula calculate, namely each unlocking pin generated is all different.

Such as, conversion formula is y=a+b+c, wherein, y represents three-character doctrine, a, b, c is variable, and when the first character of stochastic generation is 4,6,2, user is 12 according to the second character that conversion formula calculates, terminal device is also 12 according to the three-character doctrine that conversion formula calculates, therefore, when terminal device receives the second character from user by input frame, identical with three-character doctrine by comparing discovery second character, be 12, then terminal device be converted to released state by screen lock state.

Certainly, conversion formula can also be y=min (a, b, c, d), wherein, y represents three-character doctrine, a, b, c, d is variable, the character of stochastic generation is 12, 46, 15, 20, terminal device is 12 according to conversion formula determination unlocking pin, if detect that being input to unlocking pin by input frame is also 12, then determine that the unlocking pin inputted is correct, can unlock, if detect that being input to unlocking pin by input frame is not 12, then determine the unlocking pin mistake inputted, the unlock password of input cannot be utilized, namely released state can not be converted to by screen lock state.

Conversion formula can also be select capitalization in the first character of display, and such as, the first character of generation is a, b, c, D and e, and capitalization is D, then user is converted to released state by terminal device by screen lock state by input frame input alphabet D.

When utilizing above-described embodiment to carry out unlocking screen, due to stochastic generation during the first character, each unlocking pin obtained according to stochastic generation first character conversion when unlocking is also different, like this, even if unlocking pin is by other people record in public, as long as other people do not know conversion formula, also cannot unlock screen.In addition, conversion formula only just can be seen by user when arranging password, and do not show conversion formula when unlock screen, other people also cannot know conversion formula, thus avoid the leakage of unlocking pin, and then reaches the effect of the security improving unlocking pin.

Alternatively, before the conversion formula the second character and use pre-set compares the three-character doctrine that the first character is converted to, method also comprises: using the first character as entering the variable assignments of ginseng to conversion formula, obtain three-character doctrine, wherein, in first character, the number of character is identical with the number of variable, the corresponding variable of each character in the first character.

When utilizing conversion formula to change the first character, in the first character of display, the number of character is identical with the number of variable in conversion formula, like this when changing, only the first character need be brought in conversion formula.

Such as, the conversion formula pre-set is y=f (x1, x2, x3, x4), wherein, y represents three-character doctrine, x1, x2, x3, x4 are variable, and the variable in this conversion formula is four, i.e. x1, x2, x3, x4, accordingly, in the first character of display, the number of character is also four, and the first character of display is four constants a, b, c, d, a, b, c, d and x1, x2, x3, x4 are brought into one to one conversion formula y=f (x1, x2, x3, x4) in, the three-character doctrine obtained is f (a, b, c, d).

Alternatively, in order to improve the speed of unlocking operation, when showing the first character and the input frame of stochastic generation under terminal device is in screen lock state, also comprise: use conversion formula to be converted to three-character doctrine to the first character.

Use conversion formula to be converted to three-character doctrine to the first character when showing the first character of stochastic generation, just the first character conversion is become three-character doctrine before can certainly receiving the second character, can also be three-character doctrine by the first character conversion while reception second character, like this when comparing the second character and three-character doctrine, do not need again spended time to carry out the conversion of the first character to three-character doctrine, directly compare and just can determine whether the second character that user inputs is unlocking pin.

Certainly, in order to avoid the system resources consumption (such as, the consumption of internal memory or taking of storage space) that terminal device is unnecessary, the conversion of the first character to three-character doctrine can be carried out again after receiving the second character.After the second character being received input by input frame, and before the conversion formula the second character and use pre-set compares the three-character doctrine that the first character is converted to, also comprise: use conversion formula to be converted to three-character doctrine to the first character.

Such as, the screen that user lights terminal device is in order to the time of seeing, instead of in order to unlock screen, although show the first character of stochastic generation like this on screen, inputs the second character in the input frame that user can't show on screen.In such a scenario, can't be three-character doctrine by the first character conversion when terminal device shows the first character of stochastic generation on screen, but be three-character doctrine by the first character conversion again after by the time receiving the second character, the system resources consumption produced owing to calculating three-character doctrine can be reduced like this.Especially consume the larger application program of internal memory for the less terminal device of internal memory or itself, after reception second character, carry out the first character more proper to the conversion of three-character doctrine.

Alternatively, before the first character showing stochastic generation under terminal device is in screen lock state and input frame, method also comprises: receive and be used for requesting terminal equipment is switched to released state request instruction by screen lock state; According to request instruction stochastic generation first character.

Usual terminal device is in black state when screen lock state, or only shows Background Picture.Receive at terminal device and be used for after requesting terminal equipment to be switched to the request instruction of released state by screen lock state, generating the first character according to request instruction.

Such as, when the terminal such as mobile phone or panel computer is unlocked, the terminal device being in black state is waken up into illuminating state, after screen is lit, namely occur the unlock interface for pointing out input unlocking pin, the instruction that the action of now lighting screen produces in terminal device can be considered as requesting terminal equipment is switched to released state request instruction by screen lock state.Certainly, can not be there is the unlock interface for pointing out input password in some situation, also need to perform relevant operation (such as according to the activity operations that the icon of " please slide to unlock " that screen shows performs) and could occur above-mentioned unlock interface after screen is lit.In such a scenario, perform and relevant operate in the instruction produced in terminal device and can be considered as requesting terminal equipment is switched to released state request instruction by screen lock state.After receiving request instruction, generate the first character, the unlock interface of display shows the first character of generation.

Such as, when application program in terminal is unlocked, the interface of terminal device display application program, when clicking the file checked and need input password just can check, eject the unlock interface of input password, now, the action clicking file can be considered as requesting terminal equipment is switched to released state request instruction by screen lock state.After receiving request instruction, generate the first character, the unlock interface of display shows the first character of generation.

Alternatively, the first character showing stochastic generation under terminal device is in screen lock state comprises: repeat following steps until display the first character: judge whether the number of data bit in the three-character doctrine be converted to according to the first character and the conversion formula of stochastic generation is less than or equal to the number of display box in input frame; If the number of data bit is less than or equal to the number of display box in three-character doctrine, then show the first character; And if the number of data bit is greater than the number of display box in three-character doctrine, then stochastic generation first character again.

When the number of display box is fixed in input frame, when generation the first character, the number of data bit in the three-character doctrine considering to be converted to according to conversion formula is needed whether to be less than or equal to the number of display box.When the number of data bit is less than or equal to the number of display box in three-character doctrine, the code error inputted may be caused, or unlocking program is made mistakes.Therefore, when generation the first character, need to judge whether the number of data bit in the three-character doctrine the first character conversion obtained according to conversion formula is less than the number of display box, if judged result is yes, then show the first character, if judged result is no, then stochastic generation first character again.

As shown in Figure 7, generate the first character and comprise four, be four 9, and input frame is four input frames, conversion formula is y=a ²× b × c × d, wherein, y represents three-character doctrine, a, b, c, d are variable, be 59049 by the three-character doctrine obtained after the first character conversion, each display box of input frame can only show a data bit, and obvious four display boxes cannot meet the requirement of five data bit of three-character doctrine.Therefore, when in the three-character doctrine be converted to, the number of data bit is greater than the number of display box, will stochastic generation first character again, until the number of data bit is less than or equal to the number of display box in the three-character doctrine obtained via the first character conversion of stochastic generation.

Such as, input frame has 4 display boxes, and conversion formula is y=a+b, and wherein, y represents three-character doctrine, and a, b are variable.In order to the number of the data bit making the three-character doctrine be converted to is less than or equal to 4, can limit y=a+b<10000, the data bit of the three-character doctrine utilizing the first character to calculate like this is less than or equal to 4.

Pass through above-described embodiment, can judge before display first character whether the number of data bit in the three-character doctrine after changing is less than or equal to the number of display box, if the number of data bit is less than or equal to the number of display box in three-character doctrine, then directly show the first character generated, if the number of data bit is greater than the number of display box in three-character doctrine, then again stochastic generation first character until in three-character doctrine after conversion the number of data bit be less than or equal to the number of display box.According to above-described embodiment, can to ensure the first character conversion of display according to conversion formula to be three-character doctrine, and in three-character doctrine, the number of data bit is less than or equal to the number of display box, thus avoids unlocking pin to report an error.

Alternatively, in order to make the range of choice of dynamic password larger, the number of data bit in the three-character doctrine be converted to can not also be limited, when the number of data bit in three-character doctrine is less than the number of display box or is greater than the number of display box, use conversion formula to be converted to three-character doctrine to the first character to comprise: whether the number comparing data bit in three-character doctrine is less than the number of the display box of input frame, wherein, each display input character; If the number of data bit is less than the number of display box in three-character doctrine, then three-character doctrine below supplement predetermined symbol until in three-character doctrine the number of data bit identical with the number of display box; If the number of data bit is greater than the number of display box in three-character doctrine, then extract the predetermined number of three-character doctrine according to position, wherein, predetermined number is identical with the number of display box according to the number of position.

Unlocking pin is as shown in Figure 7 on inputting interface, input frame has four display boxes, each display box can receive a data bit of the second character, when not limiting the number of data bit of the result the first character conversion obtained, when the number of the data bit of the result be converted to is greater than the number of display box, the predetermined number of the result be converted to can be extracted according to position, and receive predetermined number according to position by display box; When the number of the data bit of the result be converted to is less than the number of display box, book character can be supplemented, to make the number of the data bit of three-character doctrine identical with the number of display box in input frame.

Such as, input frame has four display boxes, and the first character of stochastic generation is 2,3,4,5, and conversion formula is y=a+b+c+d, and wherein, y represents three-character doctrine, and a, b, c, d are variable.The three-character doctrine be converted to is 15, but input frame has four display boxes, then can in the zero padding below of three-character doctrine, namely unlocking pin is 1500, when the second character of user's input is 1500, terminal device can be converted to released state by screen lock state.

Such as, input frame has four display boxes, and the first character of stochastic generation is 2,3,4,5, and conversion formula is y=a ²× b ²× c ²× d ², wherein, y represents three-character doctrine, and a, b, c, d are variable.Passing through and being converted to three-character doctrine is 14400, and so, can extract rear four data bit of 14400 as unlocking pin, namely unlocking pin is 4400, when the second character of user's input is 4400, terminal device can be converted to released state by screen lock state.

In the above example, when in three-character doctrine, the number of data bit is less than the display box of input frame, predetermined numeral or letter can be supplemented after three-character doctrine or above, when the number of data bit is greater than the display box of input frame in three-character doctrine, several data bit below of three-character doctrine can be intercepted or start several data bit as unlocking pin.Certainly, user, when input second character unlocks, also carries out input second character according to above-mentioned rule, is convenient to the comparison of the second character and three-character doctrine.

Certainly, input frame also can not limit the number of input data bit, according to conversion formula, the three-character doctrine that the first character conversion obtains being had how many data bit can as unlocking pin, user is not needed supplementary book character yet or intercepts book character, as long as input the character that calculates according to conversion formula being inputted the second character by input frame.

Pass through above-described embodiment, the unlocking pin of three-character doctrine as terminal device can be dynamically generated by the first character of stochastic generation, thus solve the problem that in prior art, unlocking pin security is lower, in addition, by judging the number of data bit and the number relation of input frame of the unlocking pin generated, can not make mistakes when can ensure unlock screen, to make, when unlocking pin is correct, terminal device is converted to released state by screen lock state.

Alternatively, conversion formula comprises following any one or multiple operational symbol: add, subtract, multiplication and division, get minimum value, get maximal value, delivery, take absolute value, connector and bracket.

Conversion formula can comprise multiple operational symbol, and multiple operational symbol can be used in combination.Except the additive operation in above-mentioned example, multiplying and square operation, the computing such as maximal value, minimum value can also be got.

When getting maximal value, user can select maximum numeral as the second character from the first character of display, and by the maximum number in the first character as unlocking pin, certainly, three-character doctrine is also numeral maximum in the first character.

It should be noted that, for aforesaid each embodiment of the method, in order to simple description, therefore it is all expressed as a series of combination of actions, but those skilled in the art should know, the present invention is not by the restriction of described sequence of movement, because according to the present invention, some step can adopt other orders or carry out simultaneously.Secondly, those skilled in the art also should know, the embodiment described in instructions all belongs to preferred embodiment, and involved action and module might not be that the present invention is necessary.

Through the above description of the embodiments, those skilled in the art can be well understood to the mode that can add required general hardware platform by software according to the method for above-described embodiment and realize, hardware can certainly be passed through, but in a lot of situation, the former is better embodiment.Based on such understanding, technical scheme of the present invention can embody with the form of software product the part that prior art contributes in essence in other words, this computer software product is stored in a storage medium (as ROM/RAM, magnetic disc, CD), comprising some instructions in order to make a station terminal equipment (can be mobile phone, computing machine, server, or the network equipment etc.) perform the method for each embodiment of the present invention.
