Road and the detailed description of method, in case unnecessary details hinders description of the invention.
In order to illustrate technical solutions according to the invention, illustrated below by specific embodiment.
Embodiment one：
Fig. 1 shows that the present invention first implements a kind of flow chart of finger prints processing method of offer, it is noted that this
In embodiment in " the first fingerprint ", " the first backup fingerprint template ", " the second fingerprint ", " the second backup fingerprint template " "
One ", " second " does not have physical meaning, is only used for distinguishing different fingerprints, backup fingerprint template.Details are as follows：
Step S11, the first fingerprint is obtained, the first fingerprint of acquisition is stored in the current finger print template of internal memory.
Specifically, after user sends fingerprint typing instruction in terminal device, user presses the specific bit of the terminal device
Put, now, the terminal device will obtain the first fingerprint, specially obtain image information corresponding to first fingerprint, then will obtain
Image information deposit internal memory current finger print template.
Specifically, when terminal device is mobile terminal, the schematic diagram of the mobile terminal is as shown in Fig. 2 in fig. 2, be somebody's turn to do
Mobile terminal includes memory 201, processor 202, input equipment 203, output equipment 204, bus 205.
Step S12, the current finger print template is stored in file system, obtains system fingerprint template, and described in backup
System fingerprint template, obtain the first backup fingerprint template.
Because the internal memory of terminal device can not preserve corresponding information for a long time, therefore, first is stored in current finger print template
After fingerprint success, the current fingerprint template is stored in the file system of the terminal device, so as to preserve the current finger for a long time
Line template, in order to distinguish, the current finger print template for being stored in file system is named as system fingerprint template.Back up the system fingerprint mould
Plate, the first backup fingerprint template is obtained, i.e., in file system, system fingerprint template and the first backup fingerprint template be present, this
The content of two fingerprint template storages is identical.
Alternatively, after the step S12, including：
A1, the second fingerprint is obtained, the second fingerprint of acquisition is stored in the current template.Specifically, if terminal device one
Secondary property can the multiple fingerprints of typing, then after the fingerprint of typing first, continue obtain the second fingerprint, and by second fingerprint be stored in internal memory
In current template, i.e., after the fingerprint of typing first and the second fingerprint, current template stores the first fingerprint and the second fingerprint two
Individual fingerprint, certainly, if the fingerprint number of terminal device typing is more than 2, the fingerprint number of current template storage is also greater than 2.
It is pointed out that the first fingerprint and the second fingerprint here can correspond to identical user, different users can also be corresponded to,
For example, it is assumed that user corresponding to the first fingerprint is user A, then user corresponding to the second fingerprint can be user A, or use
Family B.
A2, the current finger print template backup is the second backup fingerprint template and is stored in the file system.
A3, the current finger print template is stored in the file system, and replaces original system fingerprint template.Specifically
Ground, after terminal device has stored the current finger print template comprising fingerprint, if obtaining the second fingerprint again, first will
Current finger print template backup is the second backup fingerprint template and is stored in file system, then current finger print template is stored in into file system
System, in such manner, it is possible to which the second backup fingerprint template is stored in into file system with most fast speed, realize the standby of current finger print template
Part.

Backup template.Specifically, it will rename that (system refers to for system fingerprint template after current finger print template is stored in file system
The fingerprint number of line template storage is identical with the fingerprint number that current finger print template is stored in), to replace original system fingerprint mould
Plate.
If it is pointed out that after the second fingerprint is obtained, terminal device can also continue to obtain the 3rd fingerprint, the 4th finger
The fingerprint of the predetermined numbers such as line ..., then its specific implementation procedure is similar with A1~A4's, and difference is the 3rd fingerprint, the
The fingerprints such as four fingerprint ... replace the second fingerprint, and here is omitted.
Alternatively, because the speed that current finger print template is called from internal memory is faster than from file system call current finger print template
Speed, therefore, after step s 12, including：
By in the system fingerprint template deposit internal memory of the file system, current finger print template is obtained.Due to inside
Middle deposit current finger print template is deposited, then can directly extract the current fingerprint template and the finger of collection during subsequent match from internal memory
Line matches, so as to improve matching speed.It is pointed out that current finger print mould in internal memory is not deleted after matching terminates
Plate, still retain the current fingerprint template.
Step S13, detect whether to receive designated order, the designated order includes：Unlock instruction, fingerprint after start
Typing instructs.
Due to being turned back in terminal device and releasing process needs to import information into internal memory again and (such as led current template
Enter internal memory), or, preserving the unexpected power down of process of fingerprint template or more preparative layers encapsulation chip (also referred to as MCP memories)
(Multi-Chip-Package, MCP) may all cause fingerprint template to be damaged extremely, therefore, in order to find in advance
Whether user is subsequently capable of the fingerprint matching function of using terminal equipment, then can detect whether to receive designated order in advance.
Step S14, after designated order is received, whether detection current finger print template is abnormal, the current finger print template
To be stored in the system fingerprint template in internal memory from the file system.
After any one instruction in designated order is detected, whether detection current finger print template is abnormal, different so as to realize
Normal detection in advance, and then improve the efficiency solved the problems, such as.
Alternatively, the step S14 includes：
B1, after designated order is received, detection current finger print template whether deleted, or, detect current finger print mould
Whether the designated character of plate is lost.
B2, deleted in current finger print template, or, when the designated character of current finger print template is lost, described in judgement
There is exception in current finger print template, otherwise, it is determined that exception is not present in the current finger print template.

Settled preceding fingerprint template exists abnormal；Or because the beginning field and/or trailer field of current finger print template include designated word
Symbol, therefore, can by detect the beginning field of the current fingerprint template and/or the designated character of trailer field whether lose or
It is no destroyed, if so, it is abnormal then to judge that current finger print template is present.
Step S15, in current finger print template exception, the first backup fingerprint template is deposited from the file system
Enter internal memory, and replace the current finger print template.
In the step, if it is determined that the current finger print template gone out in internal memory has exception, then first is extracted from file system
Backup fingerprint template, and the first backup fingerprint template of extraction is replaced into the current finger print template in internal memory.Certainly, if file system
System also has current finger print template, then equally will currently refer in the information alternate file system of the first backup fingerprint template storage
The information of line template storage.
