Novel RFID Authentication Schemes for Security Enhancement and System Efficiencyrity flaws and enhance privacy protection to the owner of an object with RFID tag attached on it. In addition, we develop an efficient identity match and retrieval mechanism to relieve the heavy computation load of traditional match scheme between received tag identity and records in backend database of RFID systems.

Query Rewriting Algorithm Evaluation for XML Security Views query answering, these queries later undergo rewriting so that they are valid over the original DTD schema, and thus the query answer is computed from the original XML data. We provide an algorithm for query rewriting and show its performance compared with the naive approach, i.e. the approach that requires view materialization.

A Three-Dimensional Conceptual Framework for Database Privacye the privacy of queries submitted by a data user). Examples are given to clarify why these are three . dimensions. Some of the pitfalls related to combining the privacy interests of respondents, owners and users are discussed. An assessment of database privacy technologies against the three dimensions is also included.

A Unified Conflict Resolution Algorithmauthorization conflicts is quite a challenge due to the existence of sophisticated inheritance hierarchies and the diversity of ways to combine resolution policies. Some researchers have addressed conflict resolution for tree-structured hierarchies, and others have applied a simple conflict resoluti

Refinement for Administrative Policiesh practical requirements. This paper builds on earlier work where we defined administrative policies for a general class of RBAC models. We present a formal definition of administrative refinement and we show that there is an ordering for administrative privileges which yields administrative refinem

Authenticating kNN Query Results in Data Publishingay be untrusted or susceptible to attacks, it could produce incorrect query results. In this paper, we extend the signature-based mechanism for users to verify that their answers for . nearest neighbors queries on a multidimensional dataset are complete (i.e. no qualifying data points are omitted),
