[embodiment]
Describe the specific embodiment of the present invention in detail below in conjunction with accompanying drawing.
While adopting cipher-code input method of the present invention, the user adopts graphics mode to realize Password Input, and overall procedure as shown in Figure 1.Basic procedure is as follows:
The user starts the application that needs the input account number, as the accounting class service application, mobile terminal prompting user inputs password, the user now can confirm to select Password Input (being that the user selects the Password Input acknowledgement key), as selected Password Input, by mobile terminal, detect the user cipher input action, the user gets final product the graphing password, after completing, the user selects the complete key of Password Input, the figure of by the test pattern module of mobile terminal, the user being drawn again carries out translation operation, if operation result is identical with the password set in advance, open this application, otherwise providing prompting requires the user to re-enter.In this process, the user, after selecting the Password Input acknowledgement key, if within the predetermined time without input, is considered as the Password Input failure.And if mobile terminal is changed while calculating, if the figure block counts that result is input is greater than or less than predetermined length, be considered as the Password Input failure.
In above-mentioned flow process, tradition is inputted the mode of password relatively, Main change is: " user is by key-press input numeral or character " is updated to " user's graphing password ", be that the user draws the graphical passwords presetted on the mobile terminal touch display screen, operations such as (as drawn the pentagram figure as the input password on touch display screen); Simultaneously, increased flow processs such as " terminal are changed calculating to user's input ".
Adopt graphical data-in, detection and Data Enter that this programme is mainly realized figure by touch screen device and the driving identification software thereof of support multiple point touching.
When the starting terminal figure is inputted, the test pattern module is carried out the division of figure block to the whole zone of the touch display screen of mobile terminal, as shown in Figure 2.When the user carries out graphic plotting on the touch display screen of mobile terminal, touch screen driver software touches input signal by the user and submits to the test pattern module, and the test pattern module will be detected user institute graphing.
At first, as shown in Figure 2, according to coordinate (C, 3), whole screen area is divided into to upper right, bottom right, upper left, zone, four of lower-lefts, detects the input in each zone, detect this input is linear mode or graphics mode simultaneously;
Secondly, for full screen, linearity, non-linear, pattern analysis are carried out in input, form analytical element: for the linearity input, will carry out orientation judgement and combination (cross-domain demonstration block) to each independent lines, as horizontal line, vertical curve, right oblique line, left oblique line etc.; For non-linear input, will judge its radian and corresponding line, as circle, semicircle, left camber line, right camber line etc.
Finally, for all analytical elements, carry out comprehensive and identification, as identify pentagram pattern or three left oblique lines and two right oblique lines etc. of disjunctor.
After all recognition elements have been identified, the test pattern module is transferred to the encoding of graphs switching software by recognition element and is carried out the code conversion processing.
The test pattern module is submitted recognition element in three kinds of modes the most at last:
(1) recognition element separated:
This mode is submitted to each the linear and non-linear element separated the most at last, and as three left oblique lines and two right oblique lines etc., single-element wherein is defined as component;
(2) describable graphic element:
This mode is submitted to discernible figure the most at last, such as circle, and square, pentagram, trapezoidal etc., single-element wherein is defined as component;
(3) recognition element separated and the combination of describable graphic element:
This mode is the combination of above-mentioned two kinds of modes.
Mobile terminal defines in advance to all pattern input modes, and integrated graphics input conversion table, when new figure input occurs when, obtain corresponding character code according to conversion table, and utilization figure transfer algorithm, thereby realize the figure input of mobile terminal and the mapping of corresponding character code, complete the input function of conventional cipher.
Simultaneously, mobile terminal can be adjusted the coding corresponding relation as required, and to encoding, corresponding character is adjusted.
But for the user, figure input conversion table and figure transfer algorithm are built in terminal software, and the user is invisible, that is the user do not need to be concerned about that a certain figure encodes corresponding to certain, only needs to keep the consistance of figure input to get final product.
When recognition element that the test pattern module submit to be separated, transfer algorithm will extract the linearity of separation or nonlinear patterns component as initial conditions, obtain corresponding character code sequence;
When the submission of test pattern module can be described the recognition element of figure, transfer algorithm directly extracts the character code sequence that this figure is corresponding; (can describe figure corresponding to a plurality of character code sequences for one)
The recognition element submit to separated when the test pattern module and can describe the recognition element of figure the time, corresponding character code sequence entire combination list entries as a whole with each; Its sequencing the figure block divide from left to right, order is as the criterion from top to bottom.Table 1 item is a kind of example of figure input conversion table:
Table 1
| The space action sequence | The linear figure component | The nonlinear patterns component | Figure can be described | Character code |
| Horizontal line | 1 | 0 | 0 | 1 |
| Vertical curve | 1 | 0 | 0 | 2 |
| Left oblique line | 1 | 0 | 0 | 3 |
| Right oblique line | 1 | 0 | 0 | … |
| … | … | … | … | a |
| Left camber line | 0 | 1 | 0 | b |
| Right camber line | 0 | 1 | 0 | c |
| Wave | 0 | 1 | 0 | d |
| … | … | … | … | e |
| Pentagram | … | 1 | f | |
| Circular | 1 | @ |
Further give an example, the user utilizes touch-screen to draw a vertical curve and a pentagram in interface for password input, and according to table 1, corresponding character code is 2f.
Pre-defined by different graphic characters, can realize the password combination that complexity is different.
When the terminal notifying user inputs password, the user needs the beginning of notification terminal action input so that the background monitoring that terminal figure detection module carries out the figure input, and starts the timer of figure input in order to start overtime clocking.
The concrete operations mode that starts to confirm mainly realizes (default when terminal is dispatched from the factory by specific key-press input, and can arrange in interface and revise in terminal), the user inputs specific keys, after terminal detects this information, now terminal starts test pattern module monitors user's Password Input figure, and timer starts to clock.
In like manner, after the user action input, need the notification terminal Password Input complete, after obtaining the specific keys information of terminal, now terminal figure detection module will stop detecting, simultaneously, the timeing closing device, the test pattern module starts to carry out the code conversion flow process of follow-up figure input.The mode of operation that finishes confirmation is identical with the concrete operations mode that starts to confirm.
The initial password assignment procedure occurs in the New Account registration phase, and now, the user adopts the mode of figure input to set new password, and terminal is carried out the code conversion of figure, and follow-up terminal will be usingd the password of this areal shape as basis for estimation.
The user is when accessing to your account the class business, and as the needs password is revised, at first the function based on this business is switched to password and revises interface, then adopts the new graphical passwords of mode typing of figure input, after this, can adopt new figure input as password.
Password Length restriction based on account class business, the Password Length of pattern input mode maybe can describe corresponding to the number of active graphical demonstration block class recognition element the character string number that figure is corresponding, when user's tablet pattern password, be greater than Password Length restriction (comprise and maybe can describe the character string number that figure is corresponding) if there is the graphical display area piece number of figure input, terminal will be informed against somebody the excessive mistake of code length, and the prompting user re-enters.Otherwise, be less than Password Length lower limit (comprise and maybe can describe the character string number that figure is corresponding) if there is the graphical display area piece number of input, terminal is informed against somebody code length and is crossed minor error, and the prompting user re-enters.
Password validity mainly refers to whether validity and the figure of figure input mate preset password, if in the figure scope that user institute graphing is not scheduled to identify in terminal, this graphical passwords input is invalid; If the figure when figure of user's input and initial password are set has large discrepancy (can improve user's experience by adjusting terminal figure identification redundance), this graphical passwords input is invalid.
The repeatability of figure input 2 modes of upchecking guarantee:
(1) guarantee the consistance of terminal to encoding of graphs, a certain figure, all the time corresponding to a certain coding, if carry out the encoding of graphs adjustment, need to be inputted the figure that original graphical passwords is reset and typing is new;
(2) guarantee that terminal has certain redundancy to the identification of figure, figure while presetting due to the impossible accurately repetition of user password, so, when mobile terminal dispatches from the factory, the identification parameter of figure input carried out to verification and redundancy adjustment, such as vertical curve, the identification range of this vertical curve is left and right 30 degree (effect when concrete angle can be according to verification is adjusted), and as shown in Figure 3, the straight line in this scope all is considered as vertical curve.
