First fingerprint image data of input, records the first fingerprints captured time and the first fingerprints captured position；
Second fingerprint image data capturing unit, the unit is used for intelligent mobile terminal capture user and passes through fingerprint Identification sensor
Second fingerprint image data of input, records the second fingerprints captured time and the second fingerprints captured position；
Fingerprint image data comparing unit, the unit was used for when the first fingerprints captured time and the second fingerprints captured time
Time interval, which is less than, specifies time interval, judges first fingerprint image data, the second fingerprint image data and user
Whether three is identical for preset fingerprint image data, if above-mentioned judgement comparative result is identical, into gesture slip side
To judging unit；If when the first fingerprints captured time and the second fingerprints captured in the fingerprint image data comparing unit
The time interval of time, which is more than, specifies time interval, then it is not once complete slip to be considered as this gesture to slide, and is abandoned herein
The comparison of fingerprint image data, returns to fingerprint Identification sensor start unit, and fingerprint Identification sensor is still within fingerprint recognition
Working condition；
Gesture glide direction judging unit, the unit is used for according to the first fingerprints captured position and the second fingerprints captured position
Judge gesture glide direction；The gesture glide direction judging unit includes gesture judgement of slide rule-definition module, the mould
Block is specifically included again：
Reference axis setting up submodule, the submodule is used to define reference axis, and intelligent mobile terminal operating system passes fingerprint recognition
The identification region of sensor is placed in a rectangular coordinate system, and the upper left corner of intelligent mobile terminal equipment is the origin of coordinates, and terminal is set
Standby coboundary is defined as horizontal X direction of principal axis, and the left margin of screen is defined as vertical Y direction of principal axis；
Fingerprints captured position coordinates defines submodule, and the module is used to define the first fingerprints captured position e1 points and the second fingerprint is caught
The coordinate of position e2 points is obtained, the coordinate of the first fingerprints captured position e1 points is represented with (e1.getX, e1.getY), (e2.getX,
E2.getY the coordinate of the second fingerprints captured position e2 points) is represented, distanceX represents the distance of X-direction movement,
DistanceY represents the distance of Y direction movement；
Rule of judgment defines submodule, and the specific Rule of judgment that the module is used to define gesture glide direction is：
Upward sliding Rule of judgment：e1.getY–e2.getY>Delta, and distanceY>DistanceX, then direction variable
Direction=up；
Slide downward Rule of judgment：e2.getY–e1.getY>Delta, and distanceY>DistanceX, then direction variable
Direction=down；
Judgement of slide condition to the left：e1.getX–e2.getX>Delta, and distanceX>DistanceY, then direction variable
Direction=left；
Judgement of slide condition to the right：e2.getX–e1.getX>Delta, and distanceX>DistanceY, then direction variable
Direction=right；
Wherein, delta is judge the threshold value of displacement, for representing that the distance of slip just can be with when being at least greater than the threshold value
It is considered as sliding and has carried out；
Target information operating unit, the unit is used to call gesture to operate mapping table with information, is grasped according to gesture and information
Make the corresponding relation between gesture glide direction and target information mode of operation specified in mapping table, match the hand
The obtained corresponding target information mode of operation of gesture glide direction is judged in gesture glide direction judging unit, and user is chosen
Target information carry out associative operation.
8. a kind of device based on fingerprint Identification sensor safety operation file according to claim 7, it is characterised in that
The target information includes file, file, address list, photograph.
9. a kind of device based on fingerprint Identification sensor safety operation file according to claim 7, it is characterised in that
In the target information operating unit gesture and information operate the gesture glide direction of mapping table include upwards, to
Under, slide to the left, to the right.
10. a kind of device based on fingerprint Identification sensor safety operation file according to claim 7, its feature exists
In,
Gesture operates the target information mode of operation of mapping table to include shearing with information in the target information operating unit
And deletion.
11. a kind of device based on fingerprint Identification sensor safety operation file according to claim 9 or 10, its feature
It is,
Gesture is grasped with gesture glide direction in information operation mapping table with target information in the target information operating unit
The corresponding relation made between mode is specially：
Finger slides the deletion action of correspondence target information to the left, and finger slides to the right the shearing manipulation of correspondence target information.
12. a kind of device based on fingerprint Identification sensor safety operation file according to claim 7, its feature exists
In,
The device based on fingerprint Identification sensor safety operation file also includes user fingerprints typing unit, and the unit has again
Body includes：
Fingerprint typing sets request module, and the module is used for intelligent mobile terminal operating system and receives the fingerprint typing that user sends
Request is set；
Request response and fingerprint acquisition module, the module are rung for intelligent mobile terminal os starting fingerprint Identification sensor
The fingerprint of user's typing is asked and obtained using family；
Fingerprint image data memory module, the module is used for the fingerprint image that intelligent mobile terminal operating system stores user's typing
Data.
