  PREMIS: Privacy Respected Multi-user Smart Object Service Environment




Due to the development of ubiquitous computing technologies, there are research to create services

 utilizing real world information. We proposed and realized a new service platform called uPackage

 to utilize daily objects information which are acquired from the attached sensor nodes.1 uPackage

 helps and enables people solve daily object related problems. We have been recognized our systems

 value through publications and the media.

 The purpose of this proposal is uPackage to be multi-user supported system. We believe this

 will realize new services. As our life spaces, such as homes, offices, and laboratories, are shared

 by multiple users, daily objects used in the spaces are also shared by multiple users. Therefore, to

 realize multiple user supported system is crucial to realize ubiquitous computing environment. This

 proposal develops the following two mechanisms for the realization of multi-user smart object service


  1. Privacy respected mechanism to protect privacy information

   We define a region of space where smart objects are used by users. Besides, a set of users are

   also defined who has right to use the space. Users who utileze smart objects and sensor data

   are binded by the space. The data is disclosed according to a disclosure policy defined by the

   users. We call the space Privacy Respacted Area (PRA). PREMIS has a mechanism to

   offer PRA.

  2. Universal interaction to control smart objectenvironment

  This project propose Spot interaction technique that enables users to install, discovery,

 confirm and configure smart object services. Spot interaction uses coded spotlight to deal

 user information within PREMIS system. This means Spot interaction supports to configure

 privacy protection mechanism.


During the previous efforts of the Smart Object development, the one major open issue was the privacy of the information; who could access the information and what problems that caused with respect to sensitive information about people and in particular health care information and potential personal security. The Smart Object idea could be even more valuable if these problem could be solved in an elegant but practical manner.


The proposers outline an attack on this problem. The mode of attack raised a set of interesting technical and policy issues that would make the funding of this effort worthwhile. The suggested approach does indicate a path that ,while it requires careful investigation of the security of the privacy mechanisms , is in the right direction.


Based on the good efforts of the prior funded work I would expect to see a high payoff in two parts. One is to focus the developers on the issues of privacy in the design of such systems and second to allow a more practical system to be developed and potentially marketed.


I recommend they be chosen and I would be happy to manage them.
