Methods for managing private data by pervasive computing

Abstract

The invention relates to methods for managing private data by pervasive computing. According to the method adopted in the first scheme for managing the private data by pervasive computing, the private data of the user node is saved in portable pervasive computing equipment by the user node, and the private data is managed by the user. The method adopted in the first scheme has the advantage that the private data can be fully flexibly managed by the user node. According to the method adopted in the second scheme for managing the private data by pervasive computing, the private data of the usernode is sent to a database server through pervasive computing equipment, and the private data is managed by the database server. The method adopted in the second scheme realizes the pervasive computing function and meets the requirement of separating data but is obviously not flexible enough and has the disadvantages that it is hard or inconvenient for the user node to set how to provide the private data and for whom the private data is provided, the private data can not be managed conveniently by the user node, and the authority of the user node is restricted.

Description

technical field [0001] The invention proposes a new ubiquitous computing private data management method, designs a new ubiquitous computing private data management scheme, belongs to the field of ubiquitous computing, and further belongs to the field of ubiquitous computing data management. Background technique [0002] With the development of computers, mobile computing, and sensor networks, computing has become ubiquitous. Dr. Mark Wieser of the United States put forward the concept of Ubiquitous or Pervasive Computing. The ultimate goal of this computing model is to integrate the information space composed of communication and computers with the physical space where people live and work. Users "anywhere" and "transparently" obtain information services that meet their individual needs. Ubiquitous computing, which works anytime and anywhere, puts forward new requirements for the management of private data. [0003] In the ubiquitous computing environment, users can abstra...

Problems solved by technology

In addition, the data requests sent by the user nodes in the entire pervasive computing network are all served by a database server, which will inevitably cause the database server to be overloaded, the real-time service will be affected, and even the data update may be inconsistent. The crash affects the entire network data management service and other issues, which is unacceptable for pervasive computing services
