S202, safety chip judge finger print information to be processed whether with the finger print information in any one preset fingerprint template
Match.
S203, when the finger print information in finger print information to be processed and a preset fingerprint template matches, safety chip
Fingerprint authentication is generated successfully to instruct.
S204, when finger print information to be processed does not match with the finger print information of any one preset fingerprint template, safety
Chip generates fingerprint authentication failure command.
In the application one embodiment, the fingerprinting operation instruction in embodiment illustrated in fig. 2 is fingerprint store instruction.
As shown in figure 4, the step S103 in aforementioned embodiment illustrated in fig. 2 may comprise steps of.
S301, safety chip judge whether fingerprint store instruction is first fingerprint store instruction.
S302, when fingerprint store instruction is first fingerprint store instruction, safety chip makees finger print information to be processed
It is stored in safety chip for the finger print information of a preset fingerprint template, and generates to store and successfully instruct.
S303, when fingerprint store instruction is not first fingerprint store instruction, safety chip acquisition is stored in safe core
The finger print information of preset fingerprint template in piece.
S304, safety chip judge finger print information to be processed whether with the finger print information in any one preset fingerprint template
Match.
S305, when finger print information to be processed does not match with the finger print information of any one preset fingerprint template, safe core
Piece stores the finger print information of the finger print information to be processed preset fingerprint template new as one in safety chip, and generates storage
Success instructs.Otherwise, process is received.
It is not in fingerprint store instruction to increase the rich of fingerprint database in the application other embodiments
When one fingerprint store instruction, the finger print information of preset fingerprint template can not also be extracted, and without by fingerprint to be processed
The step of information is matched with preset fingerprint template, and directly store finger print information, as long as namely fingerprint storage
Instruction, stores fingerprint, this is allowed for, for some finger, if only storing a fingerprint image, subsequent use
When being verified, region when pressing area and the acquisition of finger is inconsistent at family, will lead to fingerprint matching success rate drop
It is low.
In addition, in practical applications, it is contemplated that safety just can be with after being authenticated when carrying out fingerprint storage
It executes, such as: it before fingerprint storage, can use the step in embodiment illustrated in fig. 3, the operator of fingerprint storage carried out
Fingerprint authentication, otherwise it is assumed that being illegal user, terminates process by that could input fingerprint store instruction after verifying.
In the application one embodiment, fingerprint operational order is that fingerprint deletes instruction in aforementioned embodiment illustrated in fig. 2.
As shown in figure 5, the step S103 in embodiment illustrated in fig. 2 may comprise steps of:
S401, safety chip obtain the finger print information for the preset fingerprint template being stored in safety chip.
S402, safety chip search whether that there are the finger print informations of a preset fingerprint template and finger print information phase to be processed
Matching.
S403, when matching there are the finger print information of a preset fingerprint template and finger print information to be processed, safe core
Piece deletes the preset fingerprint template found from safety chip.Otherwise, terminate.
S404, safety chip generation, which is deleted, successfully to be instructed.
The last description of embodiment shown in Figure 4 similarly before carrying out fingerprint deletion, equally can use Fig. 3 institute
Show the step in embodiment, fingerprint authentication is carried out to the operator of fingerprint storage, is referred to by the way that fingerprint deletion could be inputted after verifying
It enables, otherwise it is assumed that being illegal user, terminates process.
The application also provides a kind of data processing method, and this method is applied in the processor of wearable device shown in Fig. 1,
As shown in fig. 6, this method comprises:
