Rich media file transmission method, device and system

The invention provides a rich media file transmission method, device and system, and relates to the technical field of communication. The method comprises the steps that when a message receiving end downloads a rich media file corresponding to a first rich media file link address, a rich media file server determines whether the message receiving end has the right to download the rich media file or not according to an authentication result, and when the message receiving end has the right to download the rich media file, the rich media file corresponding to the first rich media file link address is downloaded; and the rich media file server sends the rich media file to the message receiving end, so that the terminal with the authority can download the rich media file, and the safety of the rich media file can be ensured. 本公开提供一种富媒体文件传输方法、装置和系统，涉及通信技术领域。该方法包括：在消息接收端下载第一富媒体文件链接地址所对应的富媒体文件时，富媒体文件服务器通过鉴权结果来确定消息接收端是否有权下载该富媒体文件，并在消息接收端有权下载该富媒体文件的情况下，富媒体文件服务器才将该富媒体文件发送给消息接收端，使得有权限的终端才可以下载富媒体文件，能够保证富媒体文件的安全性。
