Abstract

In order to raise data security, an embodiment of the invention discloses a method for raising data security and an apparatus thereof, relating to the information security field. The method comprises the following steps: when a server uploading data, enciphering the data according to contact person information in the data; when a target terminal downloads the data from the server, acquiring decryption information of the data according to contact person information in the target server and the contact person information in the data, and carrying out decryption on the data according to the decryption information of the data. An embodiment of the invention mainly is used for a data encryption and decryption system.

Description

technical field [0001] The invention relates to the field of information security, in particular to a method and device for improving data security. Background technique [0002] With the development of Internet technology, users can upload data in the terminal to the server, and can also download the data from the server to the terminal. When uploading or downloading data, in order to prevent the data from being stolen or tampered with by illegal users, the data can be encrypted with an encryption key and decrypted with a decryption key. [0003] However, the aforementioned encryption key and decryption key are easy to be cracked, thereby posing a great threat to data security. Contents of the invention [0004] Embodiments of the present invention provide a method and device for improving data security, which improves data security. [0005] The embodiment of the present invention adopts following technical scheme: [0006] A method of increasing data security, includ...
