Method for controlling access to devices in a pervasive embedded environment

摘要

The present invention provides a method to monitor and control the transmission of message across a network that collects and records a unique set of data about devices on the network. The collected data contains information about the operations of a device over a period of time. The data set contains unique status information recorded about that device. In the method of the present invention access control techniques are developed to control device access and message transmission across the network. A set of device privileges is created that define the message transmission capabilities for each device on the system or on the network. The present method detects an attempt by a device on the network to transmit a message across the network. After this transmission attempt detection, there is a determination of whether the transmitting device has the privilege to access and transmit this message to the intended receiving device. When the search does find a privilege, the message transmission is allowed to continue and the message will be received at the designated receiving device. When the search does not find a privilege, the message transmission is terminated and the message will go to the intended receiving device. This method also has the capability to record the message transmission transaction or any message transmission attempt in a repository of the network in a manner similar to the recordation of the status conditions of the devices on the network.
