In an embodiment, the encryption information may include the above listed encryption methods, for example, if the encryption algorithm selected by the user is a DES algorithm, the DES algorithm is added to the encryption information when encrypting the selected picture (for example, 20 pictures to be encrypted are selected from 100 pictures), and when decrypting the picture, the DES algorithm in the encryption information is acquired, so that the encrypted picture can be decrypted by using the DES method. In an embodiment, the encrypted information may be stored in the picture file by means of an encryption header, and the encrypted picture file may include the encryption header and an encryption body, where the encryption body is the encrypted picture file.
In step S204, the encrypted picture is stored in a preset naming manner.
In an embodiment, the encrypted picture may be marked by modifying a suffix of a file name of the picture, for example, the file name of the original picture is "IMG _2001. JPG", and the picture file may be identified as the encrypted picture by the user by modifying the suffix of the file name of the original picture, for example, the modified suffix is "IMG _2001. ring"; in another embodiment, the picture may also be marked by adding a mark on the file name, for example, by adding "_ enc" after the file name "IMG _ 2001", which indicates that the picture has been subjected to encryption processing, and "IMG _2001_ enc.jpg"; by the mode, even if other people know that the picture file is in the JPG format, the encrypted picture cannot be really opened.
In this embodiment, steps S201 and S202 are not steps that must be executed before step S203, and steps S201 and S202 may not be executed as long as the bracelet is bound to the mobile terminal once. The embodiment of the present disclosure is only exemplified by how to implement the binding between the bracelet and the mobile terminal in step S201, and does not form a limitation to the embodiment.
In the embodiment, the bracelet and the mobile terminal are in one-to-one correspondence, so that a user can conveniently and quickly carry out confidential processing on the picture on the mobile terminal, the picture on the mobile terminal is prevented from being randomly browsed and transmitted when other people illegally acquire the mobile terminal, the picture privacy of the user is conveniently and quickly protected, and better experience is brought to the user; the encrypted pictures are stored in a set mode, so that a user can conveniently identify which pictures are encrypted and which pictures are not encrypted.
