[embodiment]
Describe the specific embodiment of the present invention in detail below in conjunction with accompanying drawing.
When adopting cipher-code input method of the present invention, the user adopts graphics mode to realize the 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, portable terminal prompting user inputs password, the user can confirm to select password input (being that the user selects password input validation key) this moment, as selected the password input, then detect the user cipher input action by portable terminal, the user gets final product the graphing password, after completing, the user selects password input finishing key, by the test pattern module of portable terminal the figure that the user draws is carried out translation operation again, if operation result is identical with the password that sets in advance, then open this application, require the user to re-enter otherwise provide prompting.In this process, the user if there is not input within the predetermined time, then is considered as password input failure after selecting password input validation key.And if portable terminal is when carrying out conversion Calculation, if being the figure block counts of input, the result is greater than or less than predetermined length, be considered as password input failure.
In the above-mentioned flow process, tradition is imported the mode of password relatively, the main variation is: " user is by button input digit or character " is updated to " user's graphing password ", be that the user draws the graphical passwords that presets on the portable terminal touch display screen, operations such as (as on touch display screen, drawing the pentagram figure) as the input password; Simultaneously, increased flow processs such as " terminal are carried out conversion Calculation to user's input ".
Detection and information typing that the input of employing graphics mode, this programme mainly realize figure by the touch screen device and the driving identification software thereof of support multiple point touching.
When the starting terminal figure was imported, the test pattern module was carried out the division of figure block to the whole zone of the touch display screen of portable terminal, as shown in Figure 2.When the user carried out graphic plotting on the touch display screen of portable terminal, touch screen driver software touched input signal with the user and submits to the test pattern module, and the test pattern module will detect user institute graphing.
At first, as shown in Figure 2, according to coordinate (C, 3) whole screen area is divided into upper right, bottom right, upper left, four zones, lower-left, detects the input in each zone, detecting this input simultaneously is linear mode or graphics mode;
Secondly,, form analytical element:, 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 the linearity input for full screen input carrying out linearity, non-linear, pattern analysis; For non-linear input, will judge its radian and corresponding line, as circle, semicircle, left camber line, right camber line etc.
At last, comprehensively reach identification, as identify pentagram pattern or three left oblique lines and two right oblique lines etc. of disjunctor for all analytical elements.
After all recognition element identifications were finished, the test pattern module was transferred to the encoding of graphs switching software with 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 of Fen Liing:
This mode is submitted to each the linear and non-linear element that separates 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 of Fen Liing and describable graphic element combination:
This mode is the combination of above-mentioned dual mode.
Portable terminal defines in advance to all pattern input modes, and integrated graphics input conversion table, when new figure input takes place when, obtain the corresponding characters sign indicating number according to conversion table, and utilization figure transfer algorithm, thereby realize the figure input of portable terminal and the mapping of corresponding character code, finish the input function of conventional cipher.
Simultaneously, portable terminal can be adjusted the coding corresponding relation as required, and corresponding character is adjusted to encoding.
But for the user, figure input conversion table and figure transfer algorithm are built in the 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 need 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 characters sign indicating number sequence;
When the submission of test pattern module can be described the recognition element of figure, transfer algorithm directly extracted this figure corresponding characters sign indicating number sequence; (can describe figure corresponding to a plurality of character code sequences for one)
The recognition element that submit to separate when the test pattern module and can describe the recognition element of figure the time is with each corresponding characters sign indicating number sequence entire combination list entries as a whole; 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 |

| 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, the corresponding characters sign indicating number is 2f.
Pre-defined by different graphic characters, then can realize the password combination that complexity is different.
When the terminal notifying user inputed password, the user need notify the beginning of terminal action input so that terminal figure detection module carries out the background monitoring of figure input, and starts the timer of figure input so that begin overtime clocking.
The concrete operations mode that begins to confirm mainly realizes (default when terminal is dispatched from the factory by specific button input, and can be provided with in the interface in terminal revise), the user imports specific keys, after terminal detects this information, this moment, terminal promptly started test pattern module monitors user's password tablet pattern, and timer begins to clock.
In like manner, after the user action input finishes, need the input of notice terminal password to finish, after obtaining the specific keys information of terminal, terminal figure detection module will stop to detect this moment, simultaneously, timeing closing device, test pattern module begin to carry out the code conversion flow process of follow-up figure input.The mode of operation that finishes affirmation is identical with the concrete operations mode that begins to confirm.
The initial password assignment procedure occurs in the New Account registration phase, and at this moment, 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 with the password of this figure form as basis for estimation.
The user revises as the needs password when the class that accesses to your account is professional, then at first switches to password based on this professional function and revises the interface, adopts the new graphical passwords of mode typing of figure input then, 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 be described figure corresponding characters sequence number corresponding to the number of active graphical demonstration block class recognition element, when user's tablet pattern password, if the graphic presentation block number with figure input is greater than Password Length restriction (comprise and maybe can describe figure corresponding characters sequence number), terminal will be informed against somebody the excessive mistake of code length, and the prompting user re-enters.Otherwise less than Password Length lower limit (comprise and maybe can describe figure corresponding characters sequence number), then terminal is informed against somebody code length and is crossed minor error as if the graphic presentation block number with input, and the prompting user re-enters.
Password validity refers to mainly whether the validity and the figure of figure input mate preset password, if user institute graphing does not have in the figure scope of the predetermined identification of terminal, then this graphical passwords input is invalid; If the figure the when figure of user's input and initial password are set has big discrepancy (can improve user experience by adjusting terminal Figure recognition redundance), then 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, promptly a certain figure, need be imported the figure that original graphical passwords is reset and typing is new if carry out the encoding of graphs adjustment all the time corresponding to a certain coding;
(2) guarantee that terminal has certain redundancy to the identification of figure, because the figure when the impossible accurately repetition of user password is default, so, identification parameter to the figure input when portable terminal dispatches from the factory carries out verification and redundancy adjustment, such as vertical curve, the identification range of this vertical curve be about 30 degree (effect when concrete angle can be according to verification is adjusted), as shown in Figure 3, the straight line in this scope all is considered as vertical curve.
As above-mentioned graphical passwords input scheme, the mobile terminal apparatus based on graphics mode is carried out the password input mainly comprises following function and device:
(1) test pattern module can detect and typing the input pattern of portable terminal based on figure based on multi-point touch panel, promptly monitors and differentiate the figure of user's input;
