Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
In prior art, the layout of dummy keyboard is fixing, and the region and the position that namely input password in terminal are fixing, therefore, can arrange password cracking software, utilize the stationarity of keyboard to carry out decryption.Described password cracking software obtains the position of keyboard in screen, and in keyboard after the position of each button and key assignments, can by constantly adjusting command sequence to attempt input password, until password cracking success.
The invention provides a kind of method to set up of keyboard, automatically the layout of keyboard can be changed, the key position that change button value is corresponding in dummy keyboard, make password cracking software cannot know the position of dummy keyboard in screen, and the button value in dummy keyboard, thus decryption cannot be attempted.
With reference to Fig. 1, give a kind of keyboard layout method process flow diagram described in the embodiment of the present invention.
With reference to Fig. 2, give keyboard layout's schematic diagram described in the embodiment of the present invention.
Wherein, a is the first keyboard layout, and a1 is the screen portions in the first keyboard layout, and a2 is the key position part in the first keyboard layout, " 0 " " 1 " wherein ... " 9 " " * " " # " represents a key position respectively.
B is the first keyboard layout, and b1 is the screen portions in the first keyboard layout, and b2 is the key position part in the first keyboard layout, " 0 " " 1 " wherein ... " 9 " " * " " # " represents a key position respectively.
Specifically the present embodiment is discussed below in conjunction with Fig. 2.
Step 101, in current keyboard layout, receives the character string be made up of selected button value, performs cryptographic check;
Along with the development of terminal applies, the requirement of confidentiality is also more and more higher.Such as, mobile phone needs input password to use, and some vital documents in terminal also need input password just can check, some application in terminal needs input password to use.
After prompting user inputs password, can show interface for password input, during this input password of user, shown interface for password input is exactly current keyboard layout, supposes that the first keyboard layout a in Fig. 2 is current keyboard layout.User can input password under current keyboard layout, as 1234, namely clicks key position " 1 " " 2 " " 3 " " 4 " in current keyboard layout respectively, can obtain the character string " 1234 " that button value is formed.
Then in current keyboard layout, receive the character string be made up of selected button value, in Fig. 2, key position " 1 " " 2 " " 3 " " 4 " are corresponding button value 1234 respectively, the then password that inputs as this of input of character string " 1234 ", then performs cryptographic check process.
Whether step 102, detect described character string and mate with preset password;
Described preset password can be current set password, and e.g., when entering application 1, preset password is the password for applying 1 configuration, and and for example, when using mobile phone, preset password is the unlocking pin for mobile phone configuration.Password authentification is passed through just to enter the project being provided with password, as application, and mobile phone etc.
In cryptographic check process, described character string be detected and whether mate with preset password, namely verify that whether the password of input is correct.If preset password is 1234, then mate, if preset password is not 1234, then do not mate.
If so, described character string and preset password match is namely detected, then follow-up execution step 103; If not, namely detect that described character string is not mated with preset password, then follow-up execution step 104.
Step 103, to upchecking of described character string;
If described character string and preset password match, namely Password Input is correct, then upchecking to described character string, and user performs follow-up operation according to different application scenarioss, such as, can use terminal, and for example can open and viewing files etc.
Step 104, resets keyboard layout, the key position that change button value is corresponding in dummy keyboard.
In the present invention, in order to prevent password cracking software from carrying out decryption by the method for constantly attempting input command sequence, after this keyboard layout can be changed.
In fact, the display interface of terminal can demonstrate each button, then user's selection key can input the button value of this button, namely in key arrangement, each key position is stored, each key position and button value have corresponding relation, can input key key assignments by selection key position.Therefore, when resetting keyboard layout, the key position that button value is corresponding in dummy keyboard can be changed.
Such as, a1 and the a2 position of the first keyboard layout a in Fig. 2 is exchanged, turns upside down by the screen portions in the first keyboard layout and key position part, form the keyboard layout reset.The key position that before resetting, button value " 1 " is corresponding is (10,100,30,120), and the key position that after resetting, button value " 1 " is corresponding is (10,10,30,30).
And for example, by the first keyboard layout a in Fig. 2, in key position part a1, the button value of first row and second row is exchanged, the i.e. key position of the corresponding button value of script " 1 ", corresponding button value " 4 " after resetting, by that analogy, forms the keyboard layout reset.
In keyboard layout after a reset, receive the character string that is made up of selected button value to continue to perform cryptographic check.
When after replacement keyboard layout, interface for password input shown is in the terminal exactly the keyboard layout after resetting, also being about to the keyboard layout after resetting is current keyboard layout, then step 101 is returned, the character string that reception is made up of selected button value is to continue to perform cryptographic check, concrete, can above-mentioned steps be repeated, until cryptographic check is passed through.
Keyboard layout follow-uply returns step 101 after resetting, and again can receive character string, carry out Password Input and checking.After keyboard layout's change, the position of acquisition keyboard in screen that password cracking software cannot be correct, acquisition button value that also just cannot be correct.Then password cracking software is when constantly attempting inputting password, the character string once inputted before may inputting, and also possibly cannot input of character string.
In sum, the present invention in current keyboard layout, can receive the character string be made up of selected button value, then when described character string is not mated with preset password, resets keyboard layout, the key position that change button value is corresponding in dummy keyboard.Key position in the acquisition screen that then password cracking software cannot be correct, acquisition button value that also cannot be correct.When input password attempted by password cracking software; once the character string inputted before may inputting; also possibly cannot input of character string; password cracking software is made to crack failure; thus the application making to need cryptoguard to obtain in terminal, terminal file and terminal is safer, password can play its effect.
Optionally, after detecting that described character string and preset password do not mate, also comprise:
Detect input number of times and whether reach unsuccessfully threshold value, if reach threshold value, then reset keyboard layout, otherwise, again receive character string.
If described character string is not mated with preset password, input number of times under detecting current keyboard layout and whether reach unsuccessfully threshold value, wherein, if the character string of described input and preset password match, then described character string can directly by checking, do not need to record number of times, therefore, described input number of times can be the character string and the unmatched number of times of preset password that input described in current keyboard layout.Described failed threshold value is the maximum frequency of failure of character string input in a kind of keyboard layout, such as, if the frequency of failure is 3, then detects under current keyboard layout, and whether input number of times reaches 3.
If so, namely input number of times and reach unsuccessfully threshold value, then needing to reset keyboard layout, operating as performed upper routine step 105; If not, namely input number of times and do not reach unsuccessfully threshold value, then whether exceed unsuccessfully threshold value to continuing to detect the input number of times after the character string of follow-up input.
In prior art, if input number of times reaches unsuccessfully threshold value, prior art will carry out time restriction, as locked a period of time to the input of password, such as 5 minutes, could again attempt inputting password after 5 minutes.If but password cracking software continues to attempt input password after locking time, then final password can be cracked.
And the present invention is after input number of times reaches unsuccessfully threshold value, keyboard layout can be reset, make password cracking software cannot get correct button value, prevent password to be cracked, protect the safety of terminal.
Optionally, the key position that described change button value is corresponding in dummy keyboard, comprising:
1) retain each key position in dummy keyboard, change the button value that each key position is corresponding.
When resetting keyboard layout, do not change the position of each button shown in terminal, but change the button value corresponding to each position, namely can retain each key position in dummy keyboard, and change button value corresponding to each key position, to realize the replacement of keyboard layout.
As above in example, key position part a1 is constant, the button value of first row and second row in key position part a1 is exchanged, i.e. the key position (10 of the corresponding button value of script " 1 ", 100,30,120), corresponding button value " 4 " after resetting, by that analogy, forms the keyboard layout reset.
2) change each key position in dummy keyboard, and be each key position configuration button value.
When resetting keyboard layout, also can to change in terminal the position of each shown button, then be the upper corresponding button value of each position configuration, i.e. each key position in change dummy keyboard, and configure unique button value for each key position.
As above in example, a1 and the a2 position of the first keyboard layout a in Fig. 2 is exchanged, form the keyboard layout reset.The key position that before resetting, button value " 1 " is corresponding is (10,100,30,120), and the key position that after resetting, button value " 1 " is corresponding is (10,10,30,30).
Therefore, according to above-mentioned 1) described in method, in the keyboard layout of replacement, key position does not become, but the button value that each key position is corresponding has changed, therefore, behind password cracking software selection key position, the button value of expection input and the button value of actual input can change.As 1) example in, when password cracking software selection key position (10,100,30,120) are to input key key assignments " 1 ", actual button value is but " 4 ".
And adopt above-mentioned 2) described in method, in the keyboard layout of replacement, the position of each button changes, and therefore, the problem that cannot input may appear in password cracking software selection key position.As 2) example in password cracking software selection key position (10,100,30,120) to input key key assignments " 1 " time, and now there is not button in keyboard layout, therefore cannot input key key assignments.
Certainly, 2), after password cracking software selection key position also may appear in the method described in, the situation that the button value of expection input is different with the actual button value inputted, herein for enumerating, should not be understood as limitation of the present invention.
In sum, the present invention can retain each key position in dummy keyboard, changes the button value that each key position is corresponding, or, change each key position in dummy keyboard, and be each key position configuration button value.Method is flexible and changeable, and can reset keyboard layout fast by these two kinds of methods, thus realizes, when not affecting user's input, playing the effect of safeguard protection.
Optionally, in the list of key area, preserve each key position in keyboard layout; The list of various key areas is preserved in key area list group; Button value is preserved in press key contents list; The corresponding relation of each key position and button value in selected key area list is preserved in key arrangement list.
In order to change keyboard layout more quickly, the present invention can the list of preset key area, the list of described key area is suitable for preserving each key position in keyboard layout, also namely key position shown in screen is preserved, each key position corresponds to a position in screen, then all key positions in screen can form the list of a kind of key area.Such as, in Fig. 2, a and b is made up of two kinds of different key area lists, supposes: shown by a is key position in the first key area list, and shown by b is key position in the list of the second key area.And for example, in Fig. 2 shown by a is key position in the first key area list, if arbitrarily select a key position, when keeping other key positions constant, selected key position is changed to other positions in screen, then can forms a kind of new key area list.
Then selected a certain key area list, the same example, in Fig. 2, a is current keyboard layout, what then current keyboard layout was selected is the first key area list, therefore to change key position, the list of another kind of key area can be selected, its from current keyboard layout the key area list selected different, such as select b in Fig. 2 the second key area list of selecting.
Then, in selected key area list, a random acquisition key position, then can select the button value that a key position is corresponding, the described key position of common preservation and corresponding button value.
Wherein, during change key position, can the order of the corresponding button value of key position in pre-recorded described current keyboard layout, then can be still key position configuration button value according to described order behind selection key position.Such as, key position in the list of a kind of key area turns upside down with the key position part shown in a in Fig. 2, if select this key area list, if then according to described order be key position configuration button value, then the effect shown in screen can be that a1 and a2 exchanges.
The list of described key area, in order to preserve the key position shown in screen, can shape as shown in table 1:
| The numbering of key position | Position in screen |
| y1 | （10，100，30，120） |
| y2 | （40，100，60，120） |
| ...... | ...... |
Table 1
Table 1 is only a kind of form of key area list, can also comprise other forms, should not be understood as limitation of the present invention in concrete enforcement.
Wherein, the position in screen can be a coordinate position in screen, such as, be initial point with the upper left corner, is to the right positive x-axis, is positive y-axis downwards.
In actual treatment, can distinguish each key position numbering in the list of key area in advance, such as, according to from left to right, serial number from top to bottom.
Such as, in the list of key area, the key position of button value " 1 " correspondence in Fig. 2 shown by a is y1, and the key position of button value " * " correspondence is y4, and the key position of button value " 4 " correspondence is y5 etc.And for example, the key position of button value " 1 " correspondence shown by b is y1, and the key position of button value " * " correspondence is 12, and the key position of button value " 4 " correspondence is y3 etc.
Then can record the numbering of each key position in the list of key area, then just can uniquely form the list of a kind of key area by all key positions.Therefore, after selection key zone list, can configure a button value for the key position of each numbering, the coordinate position be in terminal is configured with output valve (i.e. button value).
To retain each key position in dummy keyboard, the button value that change key position is corresponding, then can retain the key area list in current keyboard layout, and for each key position, random acquisition button value, set up the corresponding relation of described key position and described button value, be described key position configuration this button value upper.
Such as, do not change selected key area list, as remain a in Fig. 2 the key area list selected, key position that then can be corresponding to original button value " 1 ", random acquisition button value, now obtaining with the probability of button value (before namely changing, the button value that in current keyboard layout, key position is corresponding) identical is before 1/12, identical likelihood ratio is lower, and all key positions probability all identical with button value is before exactly 1/(12)
12, probability is very low, can think and can not occur, if the key position in certain keyboard is more, then probability is to lower.Now in order to more guarantee that key position and button value before can not overlap, before all right pre-recorded change, the button value that in current keyboard layout, key position is corresponding, after then obtaining a button value at random, compare with record content, after not identical, just can set up the corresponding relation of described key position and described button value, if identical, then can reselect.
The present invention can also comprise keyboard layout's list, comprising the key position in keyboard layout to display and corresponding button value, the corresponding relation of each key position and button value in selected key area list is preserved in keyboard layout's list, as shown in table 2:
Table 2
Table 2 is only a kind of form of keyboard layout's list, can also comprise other forms, should not be understood as limitation of the present invention in concrete enforcement.
In actual treatment, selected key area list in keyboard layout's list, can be comprised, and preserve the key position that in selected key area list, each numbering is corresponding, and the corresponding relation of button value.
Key position as corresponding in the button value " 1 " in Fig. 2 as shown in a is y1, and the key position of button value " * " correspondence is y4, and the key position of button value " 4 " correspondence is y5 etc.And for example, the key position of button value " 1 " correspondence shown by b is y1, and the key position of button value " * " correspondence is 12, and the key position of button value " 4 " correspondence is y3 etc.
The list of described key area is suitable for preserving key position shown in screen, therefore the diverse location of key position in screen, corresponding to different key area lists, then comprise the list of a variety of key areas in the present invention, therefore the list of all key areas can be formed key area list group, change keyboard layout be, can from described key area list group selection key zone list.
Press key contents list can also be comprised in the present invention, comprise the displaying contents of button value and button, as shown in table 3:
| Button value | The displaying contents of button |
| 1 | 1 |
| * | * |
| ...... | ...... |
Table 3
Table 3 is only a kind of form of press key contents list, can also comprise other forms, should not be understood as limitation of the present invention in concrete enforcement.
Optionally, in described press key contents list, also comprise the displaying contents of button, the displaying contents of described button and button value one_to_one corresponding.
In keyboard layout, each key position correspond to the displaying contents of button, button value corresponding to this key position can be understood by described displaying contents, as " 1 " " 2 " etc. in Fig. 2 as shown in key position part, displaying contents and the button value of described button are identical, and the button value that the key position as shown " 1 " in Fig. 2 is corresponding is 1.Certainly, also may occur the situation that the displaying contents of described button and button value are not identical, the present invention does not limit this.
With reference to Fig. 3, give the first keyboard layout change flow figure in a kind of keyboard layout method described in the preferred embodiment of the present invention.
Optionally, retain each key position in dummy keyboard, change the button value that each key position is corresponding, comprising:
Step 301, empties the corresponding relation of each key position and button value in key area list selected in keyboard layout's list;
To retain each key position in dummy keyboard, change the button value that each key position is corresponding, also button value corresponding to key position is namely changed, selected key area list can not be changed, therefore can empty in keyboard layout's list, the corresponding relation of each middle key area and button value in selected key area list.
Then can comprise key area list in now keyboard layout's list, and each key position in this key area list.
Step 302, for a key area in key area list selected in keyboard layout's list, obtains a button value at random from press key contents list;
Then for a key area in key area list selected in keyboard layout's list, from press key contents list, a button value is obtained at random.Because the number ratio of key area is more, when therefore obtaining button value at random, to form the on all four probability of keyboard layout and current keyboard layout very low, the probability that namely all key areas are all identical with button value is before very low.
Now in order to more guarantee that key area and button value before can not overlap, before all right pre-recorded change, the button value that in current keyboard layout, key area is corresponding, after then obtaining a button value at random, compare with record content, after not identical, just can set up the corresponding relation of described key area and described button value, if identical, then can reselect.
Step 303, sets up the corresponding relation of described key area and described button value, and is saved in keyboard layout's list, forms the keyboard layout reset.
Then set up the corresponding relation of described key area and described button value, be the upper corresponding button value of each key area configuration, then described corresponding relation be saved in keyboard layout's list, form the keyboard layout reset.
With reference to Fig. 4, give the second keyboard layout change flow figure in a kind of keyboard layout method described in the preferred embodiment of the present invention.
Optionally, change each key position in dummy keyboard, and be each key position configuration button value, comprising:
Step 401, empties keyboard layout's list;
To change each key position in dummy keyboard, then can the list of situation keyboard layout, namely not have in keyboard layout's list to record the key area list selected, there is no the corresponding relation of individual key position and button value yet.
