A method, server and system for restricting access of a digital media server

Abstract

The invention relates to a digital media server restricted access method. The method comprises the steps of analyzing request access information transmitted by a digital media control point; extracting secrete key information and verifying the secrete key information when the request access information includes the secrete key information; mapping a corresponding directory content to the digital media control point by the digital media server after the secrete key information passes the verification. A digital media server comprises an analysis unit, a verifying unit and a transmitting unit, wherein the analysis unit is used for analyzing the request access information transmitted by the digital media control point; the verifying unit is used for extracting and verifying the secrete key information when the request access information contains the secrete key information; the transmitting unit is used for mapping the corresponding directory content to the digital media control point after the secrete key information passes through the verification. According to the method, server and system, the access authority is set by utilizing a secrete key, and security and flexibility can be realized.

Description

technical field [0001] The invention relates to a method, server and system for restricting access of a digital media server. Background technique [0002] DLNA is an organization that aims to establish an interoperable platform based on open industry standards and establish technical design rules for companies to develop digital home-related products. Its work goal is to formulate guidelines and specifications for media format, transmission and protocol interoperability based on open industry standards, liaise with other industry standardization organizations, provide interoperability testing, and carry out the formulation and implementation of digital home market plans. DLNA uses the UPNP (Universal Plug and Play, Universal Plug and Play) protocol. As long as the same protocol is followed, devices and digital media controllers that join the same network can interoperate. The Media Player of the Windows operating system contains the DLNA function. As long as the digital me...

Problems solved by technology

This method also has shortcomings, because it cannot guarantee that the IP address obtained by the digital media controller and the digital media server device is the same as the last time when it is connected to the network each time, so each time the digital media controller or digital media server This correspondence must be reset when reconnecting to the network, which makes the operation more cumbersome
