Embodiment
For a better understanding and interpretation of the present invention, below in conjunction with accompanying drawing, the present invention is described in further detail.
The invention provides a kind of method of unlocking screen.Please refer to Fig. 3, Fig. 3 is the method flow diagram according to unlocking screen of the present invention.As shown in the figure, the method comprises the following steps:
In step S101, generate in the unlock interface of mobile terminal and unlock array, this unblock array comprises multiple character, and the plurality of character is randomly dispersed on polygon;
In step s 102, detect the slide of user between described multiple character, identify according to the execution sequence of described slide character that described user slides past and draw out corresponding sliding trace in described unlock interface;
In step s 103, the character string be made up of the character identified and the unlocking pin be made up of character preset are compared, if identical both it, then described mobile terminal is unlocked.
Particularly, in step S101, in the present embodiment, described mobile terminal is such as installed Android operation system and had the mobile device slidably inputing function, such as Android touch-screen mobile phone, Android panel computer etc.In some other embodiment, that described mobile terminal includes but not limited to have installed the terminal operating systems such as Symbian, Windows Mobile, iOS, Android, Maemo, WebOS, Palm OS or Blackberry OS and there is the Portable intelligent terminal slidably inputing function, such as smart mobile phone and panel computer.It will be appreciated by those skilled in the art that, every have the electronic equipment slidably inputing function and include in the scope that the present invention protects.
Under normal circumstances, if user does not perform any operation to mobile terminal within a period of time, mobile terminal will enter lock-out state automatically.Need when user wishes to operate mobile terminal to unlock this mobile terminal, wherein, unlocking function plays the object verified user identity.When unlocking mobile terminal, first user needs to be entered by such as on & off switch triggering mobile terminals to treat released state, shows unlock interface on the screen of the mobile terminal.Further, generate in the unlock interface of mobile terminal and unlock array, this unblock array comprises multiple character, wherein, at least includes all characters forming unlocking pin in the plurality of character.Described multiple character can be one in numeral, letter, symbol, Chinese character, color lump or its combination in any.It will be understood by those skilled in the art that; the character unlocked in array is not limited only to above-mentioned numeral, letter, symbol, Chinese character and color lump; every form multiple characters in unblock array can being carried out distinguishing include in the scope that the present invention protects; for brevity, will not enumerate at this.In the present embodiment, unblock array comprises 0 to 9 and has ten numerals altogether, and all characters that is in this unblock array are all numerals, and corresponding unlocking pin is also all made up of numeral.
The multiple characters unlocked in array are randomly dispersed on polygon.Wherein, the dispersion more that described multiple character distribution mode be distributed on polygon can make character distribute, thus effectively can reduce the possibility of user misoperation.In a specific embodiment, when forming unblock array in unlock interface at every turn, described multiple character is randomly dispersed on same polygon, that is, when each generation unlocks array, this polygonal shape and its be fixing relative to the position of unlock interface, but its distribution sequence is over the polygon random.In another is specifically implemented, when forming unblock array in unlock interface at every turn, described multiple character is distributed on difform polygon, that is, when each generation unlocks array, this polygonal shape is random, and its position relative to unlock interface is also random, meanwhile, described multiple character putting in order over the polygon is random.It will be appreciated by persons skilled in the art that because polygonal concrete shape existence infinitely plants possibility, for brevity, no longer all concrete shapes that polygon may exist are enumerated at this.
Preferably, the multiple characters unlocked in array are distributed on polygonal summit.In a specific embodiment, the multiple characters unlocked in array are distributed on polygonal summit according to random order, wherein when each generation unlocks array, this polygonal shape and its be fixing relative to the position of unlock interface, that is, during each unlocking screen, the position of the plurality of character in unlock interface is fixing, but its distribution sequence is random, thus, time each user carries out unlocking screen to mobile terminal, the distribution unlocking the character in array is all different, and then unlock interface is different.In another specific embodiment, the multiple characters unlocked in array are still distributed on polygonal summit according to random order, when but each generation unlocks array, this polygonal shape and its position relative to unlock interface are all random, that is, during each unlocking screen, the position of the plurality of character in unlock interface is random, and its distribution sequence is also random.
Preferably, generate after unlocking array, in multiple characters that this unblock array comprises, any three characters are not on the same line, thus, be directed to the conventional connected mode based on straight line, can line carried out and not need through other characters between any two characters, thus ensure that two characters adjacent in unlocking pin can be the combinations of any kinds of characters, that is can not cause any restriction to the diversity of unlocking pin.Illustrate, the character unlocked in array is all numeral, if numeral 1, numeral 2, numeral 3 distribute on the same line successively, that is when numeral 1 slides into digital 3, numeral 2 is had to pass through, so just there is certain restriction to the formation of unlocking pin in this, namely can not comprise the combination of " 13 " (or " 31 ") in unlocking pin, otherwise being input as " 123 " of user can be identified when user slides into digital 3 from numeral 1.Be directed to the situation that two or more characters adjacent in unlocking pin are same characters, because the conventional connected mode user based on straight line double or continuous several times cannot slide past same character when performing slide, therefore, in one embodiment, unlock the character that can comprise repetition in the multiple characters in array, thus, then can realize the double or continuous several times of user and input same character, thus any restriction can not be caused to the formation of unlocking pin completely.
Preferably, consider the degree of strength of unlocking pin, unlocking pin at least comprises 4 characters, in this case, the unblock array corresponding with this unlocking pin at least comprises 5 characters, and that is, the polygon be made up of the character in described unblock array is at least pentagon.
More preferably, unlocking multiple character in array lays respectively on the summit of regular polygon, this distribution mode can ensure that the multiple characters unlocked in array distribute more even further, thus makes user no matter visually or operationally can obtain good experience sense to be subject to.Please refer to Fig. 4, Fig. 4 is according to the distribution schematic diagram of numeral in unlock interface in the unblock array of another specific embodiment of the present invention.As shown in Figure 4, unblock array comprises 0 to 9 and has ten numerals altogether, these ten numerals are distributed on the summit of regualr decagon, it should be noted that, these ten digital distribution modes can be expressly understood in order to help to read reader of the present invention, in figure, illustrate with dashed lines the concrete shape of regualr decagon, but in actual applications, in order to the attractive in appearance of interface and be follow-uply convenient to user's line between numbers, the concrete shape of this regualr decagon can not be out drawn.
In step s 102, when detecting that user utilizes finger (or pointer) to carry out slide for the multiple characters in this unblock array in unlock interface, identify user's finger (or pointer) character of sliding past according to the execution sequence of slide.Meanwhile, slide according to user draws out corresponding sliding trace in real time in unlock interface, namely when user's finger (or pointer) slides from a character to another character, along with the slip of user's finger (or pointer) draws out in the mode of line the sliding trace that user points (or pointer) between these two characters.Because the distribution of the character unlocked in array when carrying out unlocking screen is all random at every turn, although therefore unlocking pin is certain, but the slide of each this unlocking pin of input due to the impact being subject to character distribution form be all different, and then to be plotted in the pattern that the sliding trace in unlock interface forms also be different at every turn.
It should be noted that, although unlocking pin is made up of character and is not made up of pattern in the present invention, and follow-uply when verifying unlocking pin be also comparison based on character string and be not the comparison based on pattern, but to carry out in slide process in unlock interface real-time rendering user to go out sliding trace and remain there is definite meaning: first, sliding trace user can be helped to confirm whether its character inputted correct; Secondly; unlock interface not only showed the mode unlocking character but also show sliding trace very strong interference had been existed to the people intentionally stealing unlocking pin; therefore effectively can reduce the possibility that mobile terminal unlocking pin is stolen by other people, protective effect is served to unlocking pin.
In step s 103, according to the character string of the character generation user input that the user identified slides past, this character string is the unlocking pin of user's input.After detecting that user completes slide, character string user inputted compares with the unlocking pin preset, if the character string of user's input is identical with the unlocking pin preset, entering after then unlocking mobile terminal can operation interface, otherwise then point out user's input error, cannot unlock mobile terminal.
With a specific embodiment, screen unlock method provided by the present invention is described below.Please refer to Fig. 5 and Fig. 6, Fig. 5 and Fig. 6 is the process schematic carrying out unlocking screen according to twice pair of mobile terminal of the present invention's specific embodiment.In the present embodiment, the unlocking pin preset is 436092, is all made up of numeral.Unblock array has ten numerals altogether by 0 to 9 and forms, and wherein, the display position of these ten numerals in unlock interface is the summit of regualr decagon just.As shown in Figure 5, in some moment, when user's triggering mobile terminals enters until released state, show in unlock interface and unlock array, ten numerals in this unblock array are distributed on the summit of regualr decagon in randomly ordered mode, particularly, be 6,8,1,9,5,0,3,4,7,2 successively according to ten numerals in this unblock array of clockwise direction.Carry out sliding in the process of unblock user, user points (or pointer) and slides from digital 4, passes through numeral 3, digital 6, digital 0, digital 9 successively until 2 (arrow represents glide direction in figure) of numeral.In the process that user's finger (or pointer) slides, the Serial No. identifying user's input according to slip order is 436092, in unlock interface, meanwhile draw out the sliding trace of user in the mode of line.After user terminates slide, Serial No. user inputted compares with the unlocking pin preset, find identically both it to carry out unlocking screen to mobile terminal afterwards, unlocking that mobile terminal successfully enters into can operation interface, user can perform associative operation in operation interface at this, such as, call, send note, photograph etc.User does not carry out any operation to mobile terminal after executing associative operation within a period of time, and now mobile terminal enters lock-out state.When user again touch mobile terminal enter until released state time, as shown in Figure 6, show in unlock interface and unlock array, ten numerals in this unblock array are distributed on the summit of regualr decagon in randomly ordered mode again, particularly, be 5,7,3,8,1,9,4,6,2,0 successively according to ten numerals in this unblock array of clockwise direction.Carry out in the process of slip unblock user, user points (or pointer) same slip from digital 4, passes through digital 3, digital 6, digital 0, digital 9 successively until digital 2 (arrow represents glide direction in figure).In the process that user's finger (or pointer) slides, the Serial No. identifying user's input according to slip order is 436092, in unlock interface, the sliding trace of user is meanwhile drawn out in the mode of line, but be different owing to unlock in array ten digital distributions in twice unlocking screen, the unblock track therefore unlock interface drawn out also is different.After user terminates slide, Serial No. user inputted compares with the unlocking pin preset, and finds identically both it to carry out unlocking screen to mobile terminal afterwards, and unlocking successfully that mobile terminal afterwards enters into can operation interface.
It will be appreciated by persons skilled in the art that the above-mentioned user of being aimed at carries out the description of unlocking screen process to mobile terminal, correspondingly, be initially at when unlocking pin is pre-set, can adopt in a like fashion.Particularly, arranging unlocking pin needs input twice usually, when the unlocking pin of twice input is identical, successfully can arrange unlocking pin.Wherein, when first time input unlocking pin, unlock character in array and be randomly dispersed on the summit of regular polygon, user realizes the input of unlocking pin by slide, draws out corresponding sliding trace arranging on interface simultaneously.When second time input unlocking pin, the character unlocked in array is still distributed on the summit of regular polygon, but sequence there occurs change, and user realizes the input of unlocking pin again by slide, simultaneously draw out corresponding sliding trace arranging on interface.Because the character distribution unlocked in twice input process in array is different, make the slide of user difference and the sliding trace that interface is drawn be set also different, therefore in the setting up procedure of unlocking pin, other people are difficult to according to the slide of user or arrange the unlocking pin that the sliding trace that interface is drawn remembers user, thus reduce unlocking pin in the provisioning process by possibility that other people steal.
It should be noted that, although describe the operation of the inventive method in the accompanying drawings with particular order, but this is not that requirement or hint must perform these operations according to this particular order, or must perform the result that all shown operation could realize expectation.On the contrary, the step described in process flow diagram can change execution sequence.Additionally or alternatively, some step can be omitted, multiple step be merged into a step and perform, and/or a step is decomposed into multiple step and perform.
Correspondingly, present invention also offers a kind of device of unlocking screen.Please refer to Fig. 7, Fig. 7 is the apparatus structure schematic diagram according to unlocking screen of the present invention.As shown in the figure, this device 20 comprises:
Random generating module 210, unlock array for generating in the unlock interface of mobile terminal, this unblock array comprises multiple character, and the plurality of character is randomly dispersed on polygon;
