Whether icon set and password icon are compared by sorting position, judge comprising the password icon in the icon set, if so,
Judgement unlocks successfully and performs step S7, if it is not, then judging unlock failure and prompting the information of unlock mistake.
The step can also be realized by second method：To each icon set in icon set result sequence, its bag is extracted
The password icon contained obtains the password icon to be verified by multiple sequentials, judges to be located at every as password icon to be verified
Whether the password icon and password to be verified of a identical sorting position are identical icons, if so, judging to unlock successfully and hold
Row step S7, if it is not, then judging unlock failure and prompting the information of unlock mistake.
Both the above method is for judging whether icon set result sequence matches with initial password, and difference exists
In：First method is actually each password icon and its sorting position in initial password, judges identical sequence position
Whether there is the icon identical with password icon in the icon set put, be password icon without removing which icon in identification icon set；
The password icon in each icon set is determined in second method actually first identification, then judges the two in identical sequence position
Whether the password icon put is identical.In the present embodiment, this step is realized using first method.
