Authority control method and system for acquiring information under distributed type cooperative environment

Abstract

The invention relates to an authority control method and an authority control system for acquiring information under a distributed type cooperative environment. The method comprises the steps: a management center receives registering requests of equipment, a user and a signal, sets an ID number, a login password and an authority, and returns the ID number and the login password; the management center receives and calibrates login information of the equipment and / or the signal, changes variable attribute information after the login information is calibrated and returns authority information; the management center receives the login information of the user, and if the authority of the user is greater than or equal to the authority of the equipment, the management center judges that the user logs in a system successfully, changes variable attribute description information of the user and returns authority information of the user, and if the management center judges that the user fails in login, the management center returns an insufficient authority; the management center sets a filtering rule according to the authorities of the equipment and the signal and returns a signal list which can be checked by the user logging in the system successfully to the equipment where the user exists according to the filtering rule. According to the authority control method and the authority control system, the security and controllability challenge caused by information intercommunication in application of a distributed type multi-service multi-player cooperative system in a control room can be effectively solved.

Description

Technical field [0001] The present invention relates to a distributed system, and more specifically, to a method and system for controlling information acquisition in a distributed collaborative environment. Background technique [0002] With the development of network technology and the increase in speed, collaborative applications in a distributed environment widely use network-based information acquisition technology, which can transmit and acquire text, multimedia, and various forms of computer output signals (herein collectively referred to as information). ), and can facilitate the interconnection and intercommunication in multiple devices of multi-person collaboration, and realize multi-person work collaboration through information sharing and interaction. [0003] The control room is a typical multi-person collaborative work environment, which mainly includes a high-resolution video wall display system (VW: Video Wall) for centralized display of information, various signal ...

Problems solved by technology

These requirements are often flexible and changeable. In the existing technology, the control room only sets and restricts the authority of users. From the perspective of information security and controllability, it is difficult for the traditional control room security strategy to meet this temporary change. The information interconnection and intercommunication needs of the company often require a lot of settings and configurations in advance, which is time-consuming and labor-intensive.
