Processing method for piecing together fingerprint based on mobile terminal and mobile terminal

A processing method for piecing together a fingerprint based on a mobile terminal, comprising:

• forming a fingerprint sharing button;
• acquiring fingerprint information of a user via the fingerprint sharing button;
• comparing the fingerprint information of the user with fingerprint information which is stored in advance and utilized for unlocking the mobile terminal;
• unlocking the mobile terminal when the fingerprint information of the user matches the fingerprint information which is stored in advance and utilized for unlocking the mobile terminal;
• acquiring and storing fingerprint information of a current operating user after the mobile terminal is unlocked and the current operating user presses the fingerprint sharing button, wherein the fingerprint information of the current operating user comprises information of fingerprint pieces;
• reading and comparing the fingerprint information of the current operating user with fingerprint information which is stored during a last time after the mobile terminal is unlocked, and then piecing the information of fingerprint pieces together to form complete fingerprint information;
• determining whether the complete fingerprint information is acquired;
• and
• acquiring and storing the fingerprint information of the current operating user after the current operating user presses the fingerprint sharing button, when the complete fingerprint information is not acquired.

A mobile terminal, comprising:

• a computer device;
• and
• a computer-readable memory medium, the computer-readable memory medium comprising codes executable by the computer device, the codes comprising:
• a sharing control module configured to cause the computer device to form a fingerprint sharing button, and the fingerprint sharing button being shared with the fingerprint identification area;
• an unlocking control module configured to cause the computer device to acquire fingerprint information of a user and to compare the acquired fingerprint information with fingerprint information which is stored in advance and utilized for unlocking the mobile terminal, and to unlock the mobile terminal when the fingerprint information of the user matches the fingerprint information which is stored in advance and utilized for unlocking the mobile terminal;
• an operating control module configured to cause the computer device to determine whether fingerprint information of a current operating user via the fingerprint sharing button matches the fingerprint information which is stored in advance and utilized for unlocking the mobile terminal, when the current operating user operates the mobile terminal after the mobile terminal is unlocked, wherein the operating control module comprises:
• an acquiring unit configured to cause the computer device to acquire and store the fingerprint information of the current operating user after the mobile terminal is unlocked and the current operating user presses the fingerprint sharing button, wherein the fingerprint information of the current operating user comprises information of fingerprint pieces;
• and
• a piecing process unit configured to cause the computer device to read and compare the fingerprint information of the current operating user with fingerprint information which is stored during a last time after the mobile terminal is unlocked, and then to piece the information of fingerprint pieces together to form complete fingerprint information.
