Display terminal, server and information security issuing system

A server, comprising a device authentication unit, a file encryption unit, and a content monitoring unit;

• wherein
• the device authentication unit is configured to perform a device authentication on a display terminal in response to a device authentication request sent by the display terminal to obtain a device authentication result, and feed the device authentication result back to the display terminal;
• the file encryption unit is configured to encrypt a target file to be issued in response to a file issuing request sent by the display terminal to obtain an encrypted authentication file;
• and
• the content monitoring unit is configured to receive an authentication result of a data content sent by the display terminal and monitor whether the data content is correct.

An information security issuing system, comprising a display terminal and a server;

• wherein the display terminal comprises a monitoring module and a display module;
• the monitoring module comprises a file request unit, an identity authentication unit and a content authentication unit;
• the server comprises a device authentication unit, a file encryption unit and a content monitoring unit;
• the device authentication unit is configured to perform a device authentication on the display terminal in response to a device authentication request sent by the display terminal to obtain a device authentication result, and send the device authentication result to the file request unit;
• the file request unit is configured to receive the device authentication result sent by the device authentication unit and send a file issuing request to the file encryption unit in response to the device authentication result indicating that the display terminal is successfully authenticated;
• the file encryption unit is configured to encrypt a target file to be issued in response to the file issuing request sent by the file request unit to obtain an encrypted authentication file;
• the identity authentication unit is configured to receive the encrypted authentication file issued by the file encryption unit according to the file issuing request, and authenticate an identity information of a data content in the encrypted authentication file;
• the display module is configured to display the data content in response to the identity authentication being passed;
• the content authentication unit is configured to determine whether the data content is correct based on a first image displayed by the display module;
• and
• the content monitoring unit is configured to receive a authentication result of the data content sent by the content authentication unit and monitor whether the data content is correct.
