The invention discloses a touch screen
mobile phone based on
fingerprint identification and a login unlocking method for the touch screen
mobile phone. A
fingerprint acquirer is arranged behind a touch screen sensing controller. When the touch screen
mobile phone is logged in and unlocked, the login unlocking method comprises the following steps of: 1, judging whether a
fingerprint sample needs to be set, and if so, providing a fingerprint input frame on a touch screen, collecting fingerprint data acquired in the fingerprint input frame and storing the fingerprint data as the fingerprint sample, otherwise, entering into the step 2 for checking; 2, collecting the fingerprint data acquired in the fingerprint input frame provided on the touch screen, comparing the fingerprint data acquired in the fingerprint input frame with the fingerprint sample, judging whether the fingerprint data is matched with the fingerprint sample, and if the fingerprint data is matched with the fingerprint sample, entering a
system of the mobile phone, otherwise, stepping into the step 3; 3, judging whether the number of checking times reaches a preset checking time upper limit, and if the number of checking times reaches the preset checking time upper limit, entering into the step 4, otherwise, returning to the step 2 for rechecking; and 4, indicating a user to input a
personal identification number (PIN) code of the mobile phone, judging whether the PIN code of the mobile phone is correct, and if the PIN code of the mobile is correct, entering into the
system of the mobile phone, otherwise, forbidding the user to enter into the
system of the mobile phone.
