We present a secure design for a map-reduce framework that guarantees preservation of privacy of the original data. We use Hadoop as a typical environment for illustration. That is, in spite of the data divisions/replications for the computations, the privacy of the original data remains invariant. Specifically, we use the novel information flow model called RWFM model that assures that in spite of...
The input-process-output (IPO) model has been used in many interdisciplinary applications to convey systems fundamentals, as exemplified in abstract diagramming of attacks on information systems. The resulting IPO-based diagram can provide a framework for identifying points of potential security concern and to develop protection strategies. This paper introduces an alternative diagramming representation...
The seamless combining with context-aware sensors and numerous devices and e-home server will soon become a part of our home environment in the near future. We name it as a context-aware home based on ubiquitous computing concept. This context-aware home reduces participations of users in order to realize a ubiquitous computing and automates various services. Therefore, the risk of privacy violation...
The sensitive information leakage accidents due to insiders were always troublesome. Based on trusted computing technologies the paper designs a model called secure information flows control model ( SIFCM for short) that will be applied in sensitive organizations. SIFCM protects sensitive information by encrypting any sensitive information flowing out of the system and guaranteeing the confidentiality...
