A privacy policy conflict detection method for multi-owner privacy data protection

Abstract

The current privacy-preserving researches focus on single-owner privacy data. However, multi-owner privacy data, which is also a widespread privacy data, need to be properly protected. At first, the characteristics of multi-owner privacy data and its protection requirement is introduced in this paper. Secondly, a data schema based on deputy mechanism for multi-owner privacy data is proposed. Thirdly, based on the schema, this paper proposes a privacy policy conflict detection method based on sub-graph isomorphic. This method models the privacy policy and each possible policy conflict pattern as a stratified-directed graph (SDG), and provides an algorithm to detect whether the SDG of a privacy conflict mode is isomorphic to that of privacy policies.Y.

Revisiting the Informed Consent Principle for Data Release

“…The multicarrier notion formulated in this paper is in (Chen et al, 2007) as a kind of external knowledge exploitable to discover sensitive data. Multi-owner privacy in (Li et al, 2010) and (Ren et al, 2011) and the multiparty privacy in, e.g., (Chen and Liu, 2009))cover privacy problems which arise when some parties jointly are actively involved in a computation task, usually on the web.…”

“…But it still changes the attributes of policies. Up to now, there are more and more researchers done in conflict detection and resolution methods, such as researchers in article [16][17].…”
