Embodiment Construction

[0032] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0033] 1) Context-aware application system operating mode

[0034] Context-aware application systems need to consider privacy protection. In context-aware application systems, users express personal privacy preferences through privacy roles, and control context-aware applications to access personal context information. The service mode of context-aware applications is determined by application developers. The service mode requires the acquisition of context information with different precision. In the pervasive environment, users dynamically assign privacy roles to context-aware applications to obtain corresponding service modes. The main functions of privacy roles are as follows:

[0035] a) The privacy role represents the user's privacy preference, and provides the choice of the release method of personal context information;

[0036]b) The privacy role is...

Abstract

The invention discloses an automatic generation method of a personal context information privacy protection strategy, which includes the steps as follows: (1) a service mode and a privacy role are analyzed and compared so as to determine the type, number and the like of the service mode; (2) a mobile agent is set as a representative in a pervasive environment for users and a system agent in the pervasive environment is set for being responsible for processing a request for personal context information of the users. Through the coordination of the mobile agent and the system agent, context information in an interactive environment is obtained; (3) various sensors in the pervasive environment can be used for obtaining the context in the interaction process of the users and a context-ware application system, namely, historical data of interaction between the users and the context-ware application system. And then the data are stored in an interactive context database; (4) a rough set algorithm is used for completing the automatic extraction of the privacy protection strategy; and (5) a privacy role analysis engine is used for automatically allocating an appropriate privacy role for the context-ware application system, namely for setting an operation mode for the context-ware application system.

Description

technical field [0001] The invention relates to a method for protecting privacy in a pervasive environment, in particular to a method for automatically generating privacy protection policies for personal context information. Background technique [0002] With the increasing development of computing and communication technology, various new devices and applications are emerging, and computing and communication capabilities are no longer a scarce resource. They constitute a ubiquitous computing and communication environment that surrounds users, that is, a new ubiquitous computing model. In a pervasive environment, the end user's attention is a precious resource, so the user only needs to focus on the task itself, and the computing and communication related to the task should be automatically completed by the pervasive system. In order to achieve this goal, context-aware application systems have been proposed to solve this problem, that is, to provide users with various automa...
