401, adopted the mode of input character by user, or on dummy keyboard, select the mode of character directly password is set and is stored as original password.
Original password comprises at least one character, can be pure digi-tal password, pure letter code, numeral and monogram password, or numeral, letter and special character combination password, Password Length is not limit, two or more identical characters can be included, do not affect realization of the present invention.Certainly, in actual applications, original password preferably can meet certain length and complexity, could improve security further.
In application process, user also independently can adjust original password as required at any time.
402, when this device enters until released state, in touch screen display one dynamic keyboard, and each distribution of the keys on this dynamic keyboard enters at this device and treats that the initial time of released state carries out stochastic transformation process.
By stochastic transformation process, make when entering until released state at every turn, the distribution of the keys on dynamic keyboard with front once compared with can be identical also can be different.
403, enter after released state at this device, the key mapping corresponding on the dynamic keyboard of current display according to described original password, automatically in order, shortest path connects the figure generated, as this unlocking pin.
Concrete method for drafting is: each character connecting original password on current dynamic keyboard according to the order of sequence, and namely the figure that all the shortest connecting line is combined to form is this unlocking pin.
In drawing process, the connecting line between adjacent two characters is limited to straight line.When adjacent two characters are different, its corresponding connecting line is formed as line segment; When adjacent two characters are identical, its corresponding connecting line is formed as a little.
Based on the method for drafting of this step, although the original password that user is arranged at initial time is constant, but all different owing to entering the distribution of the keys of dynamic keyboard when the released state at every turn, draw the figure drawn when thus can make to unlock different, namely each unlocking pin is different at every turn.

In above-mentioned unlock method, the original password that multiple numeral, letter and/or other special characters form has been changed into figure, when unlocking, user does not need to input original password, and only needs to draw out the corresponding figure of unlocking pin according to key mapping any position on the touchscreen on current dynamic keyboard.Unlocking pin all can change with key mapping at every turn, and user's graphing region is not limited on dynamic keyboard, thus greatly reduces the risk that original password leaks.
The pattern drawing method of unlocking pin and concrete pattern will be described for 3 examples below.
Example 1: suppose that the original password of user preset is 123456; Enter after released state at device, in touching the dynamic keyboard of screen display as shown in Figure 5.
So, the pattern drawing method of this unlocking pin is concrete as shown in Figure 5: each numerical character 1,2,3,4,5,6 connecting to form default original password successively, thus formation figure is as shown in Figure 6 as this unlocking pin.
Example 2: suppose that the original password of user preset is 137569; Enter after released state at device, in touching the dynamic keyboard of screen display as shown in Figure 7.
So, the pattern drawing method of this unlocking pin is concrete as shown in Figure 7: each numerical character 1,3,7,5,6,9 connecting to form default original password successively, thus formation zigzag is as shown in Figure 8 as this unlocking pin.
In this example, if the figure of user's input is zigzag equally, but input lack of standardization, error exceeds default error threshold, is such as identified as short Z, then unlock unsuccessful.
Example 3: suppose that the original password of user preset is 334225; Enter after released state at device, in touching the dynamic keyboard of screen display as shown in Figure 9.
So, the pattern drawing method of this unlocking pin is concrete as shown in Figure 9: each numerical character 3,3,4,2,2,5 connecting to form default original password successively, thus formation lightning shape is as shown in Figure 10 as this unlocking pin.
In this example, there is the situation that adjacent character is identical in original password, and the character 2 and 2 that so now adjacent character 3 and 3 is adjacent is all connected to form a little.
Example 4: suppose that the original password of user preset is 111111; So, enter after released state at device, no matter touch the distribution of the keys why sample of the dynamic keyboard of screen display, the figure of this unlocking pin is all a point, as long as the figure of user's input is a point, can unlock successfully.
Embodiment two
In embodiment one, using whole touch-screen as figure detection area, this figure detection area contains the viewing area of dynamic keyboard, and user can utilize finger or felt pen to carry out graphing in the optional position of touch-screen, although like this detection area is maximized, user-friendly.But because user adopts bimanualness (hand-held the edge of device, a hand graphing) usually, detection area is crossed conference and is made the motion track of the finger being positioned at touch-screen marginal position easily be mistaken for the figure of user's drafting, thus causes unlocking unsuccessfully.Thus, in the present embodiment two, figure detection area is suitably reduced, the zone line of touch-screen is set to figure detection area and this regional edge boundary line is highlighted, to point out user graphing in this region.Erroneous judgement can be avoided like this.Certainly, the setting of figure detection area is not limited to this, and user can be arranged according to self use habit.
Embodiment three
In embodiment one, each distribution of the keys on dynamic keyboard enters at device and treats that the initial time of released state carries out stochastic transformation process once.At user's graphing to carry out in the process that unlocks, if unlock unsuccessfully, the distribution of the keys on dynamic keyboard will not carry out conversion process, that is: when time releasing process in, this unlocking pin is constant.
Under some applied environment, for strengthening secrecy provision, need the security realizing height, thus in the present embodiment three pairs of embodiments one, the stochastic transformation frequency of dynamic keyboard strengthens, that is: working as in time releasing process, when user attempts unlocking failure, the stochastic transformation immediately of the distribution of the keys of dynamic keyboard once, and simultaneity factor draws out respective graphical automatically as new unlocking pin, attempts matching judgment standard when unlocking as user next time.
Embodiment four
In embodiment one, the set-up mode of original password is: by selecting the mode of character directly to arrange the original password be made up of character in input field input character or in dummy keyboard.This traditional set-up mode is fairly simple, but input and selection and comparison trouble.
For simplifying the setting of original password, improve and speed is set, user-friendly, the present embodiment adopts the mode of Graphic Exchanging to arrange original password, be specially: interface is set at password, on the current dummy keyboard that presents or touch-screen, detect the figure being touched drafting by user, and the key mapping on this figure and dummy keyboard is compared, will the character combination of this figure be connected to form as original password.
After the mode by Graphic Exchanging successfully arranges original password, the generation of unlocking pin and releasing process identical with embodiment one, be specially:
When device enters until released state, in touch screen display one dynamic keyboard; Enter after released state at device, the position corresponding on the dynamic keyboard of current display according to original password, automatically generate and unlock figure, as this unlocking pin.
Example 1: arrange interface at password, as shown in figure 11, detects the figure that user draws on dummy keyboard, the key mapping on this figure and current virtual keyboard is compared, and can show that original password is " 14569 ";
When device enters until released state, in touch screen display dynamic keyboard as shown in figure 12; Enter after released state at device, the position corresponding on the dynamic keyboard of current display according to original password " 14569 ", automatically generate and unlock figure " L ", as this unlocking pin;
Detect the figure of user's input afterwards, itself and this unlocking pin " L " is compared, if match, then touch-screen is unlocked.It should be noted that, if no matter the figure of user's input is large L or little L, as long as with this unblock figure equal proportion, can be judged to match, unlock.
Example 2: arrange interface at password, a point of the figure that user draws, then can show that original password has more multiple, be specially one or at least two identical characters, such as " 111 ", " 22222 " or " aa " etc.Enter after released state at device, how no matter touch the distribution of the keys of the dynamic keyboard of screen display, the figure of this unlocking pin is all a point, as long as the figure of user's input is a point, can unlock successfully.
In the present embodiment four, password is arranged dummy keyboard region on interface as test pattern region, the figure that user inputs can be detected more quickly and accurately and be converted into the character of arranged in sequence.In other embodiments, other appointed areas that also can arrange on interface at password are detected as test pattern region.
This embodiment simplifies the setting of original password, improve the speed of setting, more hommization.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
