Abstract

The invention relates to a file transmission method and device which are applied to a terminal. The method comprises the steps of: receiving a file sending instruction; judging whether the file sending instruction indicates that the file is sent to a cloud server; and if yes, sending an encrypted file to the cloud server, wherein the encrypted file is a file formed by performing encryption on original data of the file according to encryption information stored in the terminal. According to the invention, the safety of the file sent to the cloud server is improved, and the risk of user privacy leakage from the cloud server is lowered.

Description

technical field [0001] The present disclosure relates to the field of communication data security, in particular to a method and device for file transmission. Background technique [0002] With the popularization of smart terminals and the increase of files to be processed in the terminal, the memory of the terminal is increasingly unable to meet the storage requirements of users. Currently, cloud services are increasingly used by ordinary users for file backup storage. With the popularization of the Internet, people in modern society gradually realize the importance of personal privacy protection, and many people worry about the safety of files stored in cloud services. Leakage of user privacy due to cloud account theft occurs from time to time. Among them, the leakage of private photos and videos involving individuals is particularly prominent. Contents of the invention [0003] In order to overcome the problems existing in related technologies, the present disclosure...
