Dvr server and method for controlling accessing monitering device in network based digital video record system

Abstract

The present invention provides a Digital Video Recorder (DVR) server and a method for controlling access to a monitoring device in a network-based DVR system, which only performs a user authentication in the DVR server and allows a direct access to a video providing unit by using an authentication token acquired from the authentication procedure, so that traffic of the DVR server can be reduced to maintain security while providing a smooth monitoring service.

Description

technical field [0001] The present invention relates to a digital video recorder (DVR) server and method for controlling access to monitoring devices in a network-based DVR system. Background technique [0002] FIG. 1 is a schematic diagram showing a conventional monitoring system. Referring to Figure 1, most first generation surveillance systems utilize closed circuit TV (CCTV) or the like. However, surveillance systems using CCTV basically operate in such a manner that video captured by a camera is received through a coaxial cable and output on a display unit. Thus, it is not actually a telemonitoring system. Also, it uses a recording medium such as a magnetic tape for recording video, so that not only results in a reduction in video quality, but also requires a lot of time for searching for a desired video when recording is performed multiple times. Furthermore, routine system administration, such as tape replacement, is difficult to perform when there is no operator a...

However, it requires the user to hold a smart card or the like including the user's certificate or private key, and requires much effort and cost due to the complexity of the system when the system is actually implemented, so that this method is generally not adopted

[0013] In addition, in the case of connecting local client terminals through an internal network in such a network-based DVR system, due to the complexity of MAC address management and the IP address of unspecified users and the independent key for each local client for terminal authentication Complexity of management, which often neglects to perform authentication on local client terminals

However, this authentication strategy is not supported by the security requirements of limited monitoring services provided only to authenticated users
