Abstract

The invention discloses an information processing method and electronic equipment. The method applied to the first electronic equipment comprises the steps that a first instruction is obtained, wherein the first instruction is used for indicating to save first data and first metadata of the first data; the first instruction is responded, and the first data and the first metadata of the first data are locally and correspondingly saved in the first electronic equipment; a second instruction is obtained, wherein the second instruction is used for indicating to upload the first data to the second electronic equipment to be saved; the second instruction is responded, a first data uploading request information is sent to the second electronic equipment, the first data indicated to be uploaded is sent to the second electronic equipment, and second metadata of the first data is correspondingly saved, wherein the second metadata is at least used for recording data segmentation information of the first data, data block identifiers and the correlation among data blocks, the data segmentation information of the first data and the data block identifiers are supplied by the second electronic equipment, and each data block is marked by the corresponding data block identifier.

Description

technical field [0001] The present invention relates to the technical field of intelligent electronic equipment, in particular to an information processing method and electronic equipment. Background technique [0002] Users store local data on the server side through the network, which can be accessed anytime and anywhere, and the storage capacity can also be dynamically increased. However, there is also a risk of leakage of user data stored on the server side, which poses a security risk. Therefore, how to ensure the security of the user data stored on the server side is a technical problem to be solved urgently. Contents of the invention [0003] In view of this, an embodiment of the present invention provides an information processing method and an electronic device, so as to improve the security of user data stored by a server. [0004] The present invention provides an information processing method applied to a first electronic device, the method comprising: [00...
