Data transmission method and transmission system

Abstract

The invention discloses a data transmission method which includes the following steps that first intelligent secret key equipment carries out first identity verification on a user and second intelligent secret key equipment carries out second identity verification on the user; the first intelligent secret key equipment and the second intelligent secret key equipment carry out verification mutually; after the user passes the first identity verification and the second identity verification and the first intelligent secret key equipment and the second intelligent secret key equipment carry out verification mutually, the first intelligent secret key equipment transmits data to be backed up stored in the first intelligent secret key equipment to the second intelligent secret key equipment; the second intelligent secret key equipment receives and stores the data to be backed up. According to the data transmission method, the data to be backed up in the first intelligent secret key equipment can be transmitted to the second intelligent secret key equipment for backup, loss, caused by first intelligent secret key equipment loss, of information, such as user passwords can be prevented, and data transmission security can also be guaranteed. The invention further discloses a data transmission system.

Description

technical field [0001] The invention relates to the technical field of network information security, in particular to a data transmission method and a data transmission system.

Problems solved by technology

When users are faced with the situation of accurately memorizing multiple accounts and passwords, many users choose a combination of the same or similar characteristics as passwords for easy memory. Once one of the many related passwords is cracked, it will directly threaten the security of other accounts. Therefore, it has brought great hidden dangers to its information security protection; if the relevance of these multiple passwords is reduced in order to obtain higher password security strength, it will increase the difficulty of user memory and bring inconvenience to users
