Fingerprint encryption and decryption method and terminal

The embodiment of the invention discloses a fingerprint encryption method. The fingerprint encryption method comprises the steps of obtaining fingerprint information input by a user, determining the pressing time duration corresponding to the fingerprint information, and carrying out encryption on a terminal according to the fingerprint information and the pressing time duration corresponding to the fingerprint information. The embodiment of the invention further discloses the terminal with a fingerprint encryption function. In this way, the terminal can be encrypted according to the fingerprint information and the pressing time duration corresponding to the fingerprint information, and therefore decryption difficulty is increased, and safety of the terminal is improved.
