Fingerprint registration method and device and terminal thereof

A fingerprint registration device comprising:

• a processor;
• and
• a memory connected with the processor, the memory comprising a plurality of program instructions executable by the processor, the plurality of program instructions comprising:
• a determination module, configured to cause the processor to determine a fingerprint zone corresponding to a fingerprint recorded every time when the fingerprint is registered;
• a retrieve module, configured to cause the processor to retrieve feature information of the fingerprint recorded every time based on preset index types that are configured for determining a quality of the fingerprint recorded;
• a matching module, configured to cause the processor to match the feature information based on preset index information corresponding to the index types to determine whether the fingerprint recorded every time is effective, wherein the preset index information corresponds to the index types one to one;
• and
• a processing module, configured to cause the processor to signal a successful fingerprint registration if it is monitored that a number of effective fingerprints recorded reaches a preset number of fingerprint templates and to cause the processor to signal the successful fingerprint registration if it is monitored that a number of effective fingerprints recorded in each fingerprint zone reaches a preset number of zone templates correspondingly, wherein the preset number of fingerprint templates comprises a sum of a number of zone templates corresponding to each fingerprint zone.

A terminal device comprising a casing, a processor, a memory, a circuit board, and a power circuit, wherein the circuit board is disposed in a space surrounded by the casing;

• the processor and the memory are disposed on the circuit board;
• the power circuit is configured to supply power to various circuits or components of the terminal device;
• the memory is configured to store executable program instructions;
• the processor runs a program corresponding to the executable program instructions through reading the executable program instructions stored in the memory to perform following operations:
• determining a fingerprint zone corresponding to a fingerprint recorded every time when registering the fingerprint;
• retrieving feature information of the fingerprint recoded recorded every time based on preset index types that are configured for determining a quality of the fingerprint recorded;
• matching the feature information based on preset index information corresponding to the index types to determine whether the fingerprint recorded every time is effective, wherein the preset index information corresponds to the index types one to one;
• and
• signaling a successful fingerprint registration if a number of effective fingerprints recorded is monitored to reach a preset number of fingerprint templates, wherein the preset number of fingerprint templates comprises a sum of a number of zone templates corresponding to each fingerprint zone,
• wherein signaling the successful fingerprint registration if the number of effective fingerprints recorded is monitored to reach the preset number of fingerprint templates comprises:
• signaling the successful fingerprint registration if a number of effective fingerprints recorded in each fingerprint zone is monitored to reach a preset number of zone templates correspondingly.
