A copying and pasting method implemented in a data processing apparatus (100, 4200, 4400) comprising a touchscreen (140, 142) and a fingerprint obtaining module (4201, 4404), comprising: obtaining (701, 2601, 3201) a first to-be-recognized fingerprint by the fingerprint obtaining module (4201, 4404); selecting, if the first to-be-recognized fingerprint is a first preset fingerprint, copied content from a to-be-processed interface based on a touch operation acting on the touchscreen (140, 142); obtaining (703, 2606, 3203) a pasting instruction; and pasting (704, 2607, 3204) the copied content into a target area according to the pasting instruction; and wherein the obtaining a first to-be-recognized fingerprint comprises: obtaining, by using a fingerprint sensor when a touch operation acting on the touchscreen (140, 142) is detected, a fingerprint used for the touch operation; and using the fingerprint used for the touch operation as the first to-be-recognized fingerprint; and characterized in that after the selecting copied content from a to-be-processed interface based on a touch operation acting on the touchscreen (140, 142), the method further comprises: clearing the copied content when a slide operation is detected in a non-pastable area of the to-be-processed interface; clearing the copied content when it is detected that a speed at which a touch object moves to a side of the screen is greater than a preset speed; or clearing the copied content when a double-tapping operation acting on an editable area of the to-be-processed interface is detected. obtaining (701, 2601, 3201) a first to-be-recognized fingerprint by the fingerprint obtaining module (4201, 4404); selecting, if the first to-be-recognized fingerprint is a first preset fingerprint, copied content from a to-be-processed interface based on a touch operation acting on the touchscreen (140, 142); obtaining (703, 2606, 3203) a pasting instruction; and pasting (704, 2607, 3204) the copied content into a target area according to the pasting instruction; and wherein the obtaining a first to-be-recognized fingerprint comprises: obtaining, by using a fingerprint sensor when a touch operation acting on the touchscreen (140, 142) is detected, a fingerprint used for the touch operation; and using the fingerprint used for the touch operation as the first to-be-recognized fingerprint; and characterized in that after the selecting copied content from a to-be-processed interface based on a touch operation acting on the touchscreen (140, 142), the method further comprises: clearing the copied content when a slide operation is detected in a non-pastable area of the to-be-processed interface; clearing the copied content when it is detected that a speed at which a touch object moves to a side of the screen is greater than a preset speed; or clearing the copied content when a double-tapping operation acting on an editable area of the to-be-processed interface is detected. obtaining, by using a fingerprint sensor when a touch operation acting on the touchscreen (140, 142) is detected, a fingerprint used for the touch operation; and using the fingerprint used for the touch operation as the first to-be-recognized fingerprint; and characterized in that after the selecting copied content from a to-be-processed interface based on a touch operation acting on the touchscreen (140, 142), the method further comprises: clearing the copied content when a slide operation is detected in a non-pastable area of the to-be-processed interface; clearing the copied content when it is detected that a speed at which a touch object moves to a side of the screen is greater than a preset speed; or clearing the copied content when a double-tapping operation acting on an editable area of the to-be-processed interface is detected. clearing the copied content when a slide operation is detected in a non-pastable area of the to-be-processed interface; clearing the copied content when it is detected that a speed at which a touch object moves to a side of the screen is greater than a preset speed; or clearing the copied content when a double-tapping operation acting on an editable area of the to-be-processed interface is detected.
