Terminal encryption method and apparatus and terminal decryption method and apparatus

The present invention relates to the technical field of electronic information and discloses a terminal encryption method and apparatus and a terminal decryption method and apparatus. According to the terminal encryption method and apparatus and the terminal decryption method and apparatus, the terminal decryption method comprises the following steps that: an initial decryption interface is provided, wherein the initial decryption interface comprises a plurality of different icons; according to decryption operation of a user, shift processing is carried out on the icons in the initial decryption interface to obtain a verification decryption interface; icon information of a password position in the verification decryption interface is acquired; and when the icon information is the same as password information, decryption succeeds. Compared to the prior art, the terminal authorization security can be improved and privacy information of the user is protected.
