Receiving element 310, for receiving the unlock command of user at described touch-screen.

Particularly, user performs unlock command on the touchscreen, and touch-screen generates data-signal according to the operation of user and sends receiving element 310 to.

Response unit 320, for responding described unlock command, and display delayed on the touchscreen;

Judging unit 330, for judging that whether described unlock command is consistent with the unlocking pin preset with described time delay.

In actual applications, composition graphs 4 and Fig. 5, for the combination of nine grids and time delay as unlocking pin.Receiving element 310 receives the unlock command of user's input, touches the initialization interface that screen display nine grids interface phase is corresponding, can be divided into following several situation:

The first situation, the gesture path that receiving element 310 detects user's input is to the first gesture track of B point by A point, response unit 320 shows the first starting point time delay on the touchscreen, i.e. the continuous background luminance strengthening A point place for 2 times, and the time interval of these 2 times flickers is 0.2s; The gesture path that receiving element 320 detects user's input is to the second gesture path of C point by B point, response unit 320 shows the second starting point time delay on the touchscreen, i.e. continuous 3 background luminances by enhancing B point place, the time interval of these 3 times flickers is respectively 0.2s and 0.1s.Interface is switched to initialization interface again.The gesture path that receiving element 310 receives user's input is that response unit 320 shows the 3rd starting point time delay on the touchscreen by D point to the 3rd gesture path of E point, and namely refer to the background luminance of continuous 2 enhancing D points, the time interval of glimmering for these 2 times is 0.1s.The like, receiving element 310 detects user respectively and inputs the 4th gesture path and the 5th gesture path, and accordingly, response unit 320 shows fourth time delay and the 5th starting point time delay successively.Judging unit 330 judge first gesture track that user inputs to the 5th gesture path, the first starting point time delay to the 5th starting point time delay and gesture path all consistent with the unlocking pin preset with the order of time delay, then unlock described touch-screen.

The second situation, the gesture path that receiving element 310 detects user's input is when putting the first coherent gesture path of " L " type formed by A point-B point-C, response unit 320 shows First terminal point time delay on the touchscreen, the i.e. continuous background luminance strengthening C point place for 3 times, the time interval of these 3 times flickers is 0.1s and 0.2s.Interface is switched to initialization interface again.The gesture path that receiving element 310 detects user's input is when putting the second coherent gesture path of " N " type formed by D point-E point-F point-G, response unit 320 shows the second terminal time delay on the touchscreen, the i.e. continuous background luminance strengthening G point place for 4 times, the time interval of these 4 times flickers is 0.2s.Judging unit 330 judges that the coherent gesture path of the first coherent gesture path to the second that user inputs, First terminal point time delay to the second terminal time delay and gesture path are consistent with the unlocking pin of order all with default of time delay, then unlock described touch-screen.

The third situation, the gesture path that receiving element 310 detects user's input is to the first gesture track of B point by A point, response unit 320 shows the first starting point time delay on the touchscreen, i.e. the continuous background luminance strengthening A point place for 2 times, and the time interval of these 2 times flickers is 0.2s; When the gesture path that receiving element 320 detects user's input is B point to the gesture path of X point, then response unit 320 shows random wrong time delay on the touchscreen.Interface is switched to initialization interface again.The gesture path that receiving element 310 detects user's input is when putting the second coherent gesture path of " N " type formed by D point-E point-F point-G, response unit 320 shows the second terminal time delay on the touchscreen, the i.e. continuous background luminance strengthening G point place for 4 times, the time interval of these 4 times flickers is 0.2s.Judging unit 330 judges to occur wrong time delay in the unlock command that user inputs, namely judge this unlock command and unlocking pin inconsistent, then touch-screen keep lock-out state.In brief, as long as any gesture path that receiving element 310 receives is different from the gesture path preset, then response unit 320 just can show wrong time delay, and display interface is switched to initialization interface by the changing interface number of times that mobile terminal continues according to presetting, and continue the unlock command receiving user.Judging unit 330 detects wrong time delay, then judge the unlock command that user inputs and unlocking pin inconsistent, and touch-screen keep lock-out state.That is, the lasting switching at mistake time delay and interface serves the effect of undelegated operator of confusing, make undelegated operator not know which link to have inputed password by mistake in, thus add the decoding difficulty of undelegated operator, improve the information security of mobile terminal.

Further, composition graphs 6, for numeral and the combination of time delay as unlocking pin.Receiving element 310 receives the unlock command of user's input, touch-screen shows digital and that input frame interface phase is corresponding initialization interface, the first numerical ciphers receiving user's input is 1234, response unit 320 shows the first digital delay on the touchscreen, namely distinguish the background luminance corresponding to flashing numerals 1-4, and the time intervals of adjacent two numeral flickers are 0.1s.By changing interface to initialization interface.The second numerical ciphers that receiving element 310 receives user is 5678, and response unit 320 shows the second digital delay on the touchscreen, the background luminance namely respectively corresponding to flashing numerals 5-8, and the time interval of adjacent two numeral flickers is 0.2s.Judging unit 330 judges that the first numerical ciphers that user inputs, the second numerical ciphers, the first time delay, the second time delay and numerical ciphers are all consistent with the unlocking pin preset with the order of time delay, then unlock described touch-screen.If the numerical ciphers at least one times of user's input is wrong, then response unit responds wrong time delay, and display interface is switched to initialization interface by the changing interface number of times that mobile terminal continues according to presetting, and continues the unlock command receiving user.Judging unit 330 detects wrong time delay, then judge the unlock command that user inputs and unlocking pin inconsistent, and touch-screen keep lock-out state.

The tripper of the mobile terminal of the present embodiment, the unlock command of user at described touch-screen is received by receiving element, the described unlock command that response unit receives according to receiving element, and display delayed on the touchscreen, when judging unit judges that described unlock command and described time delay are consistent with the unlocking pin preset, then unlock described touch-screen.Thus significantly reduce the probability that mobile terminal is unlocked, improve the security of user profile.
