Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that obtains under the creative work prerequisite.
See also Fig. 1, be the structural representation of the first embodiment of terminal of the present invention.As shown in Figure 1, described terminal comprises: random display module 10, coordinate record module 20 and password authentication module 30, wherein:
Described random display module 10 is used for default controllable elements is carried out the randomization Graphics Processing, and described controllable elements is presented on the default background picture, and described controllable elements comprises one at least.
Concrete, terminal comprises that specifically mobile phone, palm PC, panel computer etc. have the electronic equipment of touch-screen, describe as an example of mobile phone example in the present embodiment.
The controllable elements of 10 pairs of user presets of described random display module is carried out the randomization Graphics Processing, described controllable elements is presented on the background picture with complete irregular random fashion, described controllable elements can be preset as one, also can be preset as a plurality of, its quantity is more, and the decoding of this picture password and/or the risk of leakage are lower, and degree of safety is higher, also increase but remember simultaneously difficulty, so the controllable elements that the user should be suitable according to the s own situation magnitude setting.
Suppose in the present embodiment, user preset three controllable elements.
Described coordinate record module 20 is used for recording the position coordinates of described controllable elements on described background picture.
Concrete, the user on the touch-screen of mobile phone can according to own working rule when password is set to described controllable elements pull, stacking, the control operation such as amplify, dwindle, corresponding change will occur in the position coordinates of described controllable elements, and described coordinate record module 20 can record described controllable elements final position coordinates that stops on described background picture.
Because described random display module 10 is when the user enters the cell phone password inputting interface each time, all described controllable elements has been carried out the randomization Graphics Processing, then user's control operation to described controllable elements when inputting password each time just is different from once, therefore, even peeped by the stranger once in a while or photographed whole Password Input process by camera, also can not cause easily the leakage of this picture password.
Certainly, do not get rid of this controllable elements the display position on the background picture with on the identical this very special situation of once display position occur, then this control operation to described controllable elements of user just can not change.
Described password authentication module 30 is used for the position coordinates generating cipher input message according to described coordinate record module 20 records, and finishes password authentification according to described Password Input information.
Concrete, suppose that the authentication password information that the user arranges is: horizontal ordinate or the ordinate of three described controllable elements are identical, namely when the user is arranged in straight line with described controllable elements, can realize deciphering.Described password authentication module 30 is carried out password authentification according to described Password Input information, when the horizontal ordinate of each final stop place of described controllable elements of described coordinate record module 20 records or ordinate when being consistent, the then password authentification of described password authentication module 30 success, mobile phone can be deciphered smoothly.
The embodiment of the invention is by carrying out the randomization Graphics Processing to the controllable elements in the picture password, controllable elements is presented on the background picture with a kind of irregular random fashion, the user is also thereupon at every turn different to the control operation of described controllable elements, therefore can successfully avoid because being peeped by the stranger or being taken the password leakage problem that password setting and/or input process cause by camera, effectively strengthen the security performance of picture password, improved user's experience.
