Password setting provided by the invention and verification method merge password figure and music (constituting multi-C vector jointly), have the following advantages than prior art:
1, in checking key string (first dimensional vector) simultaneous verification time series (second dimensional vector), promoted cipher safety, this time series has comprised user's button custom, even peeped in the input process, also is difficult to forge password;
2, adopt vector calculation, realization music rhythmization, promoted the interest of user's aesthetic feeling, enjoyment and interactive mode, such as: the user can also expand to other musical instrument as input through playing piano input password;
3, utilize the memory of music assisted user, the user can directly use the melody fragment of oneself being familiar with as password like this.
Description of drawings
Further the present invention is elaborated below in conjunction with accompanying drawing and specific embodiment:
Fig. 1 is the schematic flow sheet of the password initial set up routine of the specific embodiment of the invention;
Fig. 2 is the schematic flow sheet of the password input validation program of the specific embodiment of the invention.
Embodiment
The thinking of the specific embodiment of the invention at first, is described:
1. provide a kind of interesting interactive mode to let the user input password, and this password can comprise the information abundanter than numerical character, be identified more accurately, remembered by the user more easily simultaneously;
2. give piano key page of user, this page can be play the corresponding key sound of user key-press.Because the tune of music is remembered than numerical character more easily, the fragment in the music that the user can directly learn by heart with oneself is as the password that is provided with; Further also can use the method for liking tune+familiar numeral, as: the birthday numeral was imported by the time interval of liking tune;
3. the user is when playing melody by key, has user's time interval habitually between two keys, and this interval can be used as the additional information of password, carries out except that password figure, second taking turns checking;
4. for guaranteeing the accuracy of password authentification, when the user imports initial password, need repeatedly input, the vector angle of the button time interval correspondence of twice input to the last is all in an error threshold scope.When checking time, the vector angle that also requires the button time interval any one in password and the original password of input is in same threshold range.
The second, the key of the specific embodiment of the invention, time interval vectorization are described:
When the user imports password with key,, then can obtain a time series { t who comprises n-1 element if imported n key
1, t
2..., t
N-1, this just is a multi-C vector.In mathematical operation, the measurement foundation that the similarity of two multi-C vectors of comparison is used usually is the angle between them.Therefore, when the coupling interarrival is whether consistent, can adopt the following step:
1. be that unit converts vectorial α and β into the millisecond with interarrival;
2. the angle theta between calculation of alpha and the β;
The cosine law according to expansion then has:
Further launch, then have:
3. θ and threshold value are compared
The threshold value that the specific embodiment of the invention is chosen is-5 ° to+5 °, if θ in this scope, representes then that interarrival matees.
At last, the program that specifies the specific embodiment of the invention realizes:
(1) password initial setting up
As shown in Figure 1, the password initial set up routine specifically may further comprise the steps in the specific embodiment of the invention:
1001) demonstration piano key interface treats that the user imports;
1002) user plays piano key, further plays corresponding key sound, and the time interval when the key sequence (being corresponding key string) pressed of record is pressed with adjacent key simultaneously is that unit conversion is the multi-C vector preservation with the millisecond with the time interval;
1003) judging this input input whether for the first time, is to return step 1001), otherwise get into next step;
1004) judge with whether input key code is consistent for the first time, be to get into step 1008), otherwise return step 1001);
Whether the vector angle in the button time interval of 1005) relatively judging twice input is to get into next step between-5 ° to+5 °; Otherwise return step 1001);
1006) corresponding key sequence and vector are preserved as combination pin;
1007) finish.
(2) password input validation
As shown in Figure 2, password input validation program specifically may further comprise the steps in the specific embodiment of the invention:
2001) demonstration piano key interface treats that the user imports;
2002) user plays piano key, further plays corresponding key sound, and the time interval when the key sequence (being corresponding key string) pressed of record and adjacent key are pressed simultaneously is that unit conversion is a multi-C vector with the millisecond with the time interval;
2003) judging whether input key code is consistent with the key sequence of being preserved in the combination pin, be to get into next step, otherwise authentication failed gets into step 1006);
2004) relatively judge between button time interval vector and the vector of being preserved in the combination pin angle whether between-5 ° to+5 °, be entering next step; Otherwise authentication failed gets into step 1006);
2005) checking is passed through;
2006) finish.
At last, the above is merely preferred embodiment of the present invention, and all equalizations of being done according to claim scope of the present invention change and modify, and all should belong to the covering scope of claim of the present invention.
