obtained some interesting simulation results. In the third scenario, we assume that the partners areuntrustworthy. Here, we apply data mining to defend our systems from virus and worms and at the sametime try to probe into our partners’ systems.This research has now resulted in a MURI project. We are investigating incentive-based informationsharing and risk-based access control.Area 2: Secure Geospatial Data Management: Funding from NGA, RaytheonIn the area of secure geospatial data management, we are developing technologies for geospatial semanticweb and data mining. We are specifying extensions to GML for access control policies, as well asdeveloping ontologies for geospatial data. Using these ontologies, we are conducting data mining. Inaddition, we are also developing geospatial web services. Finally, we are developing a new languagecalled GRDF (Geospatial Resource Description Framework) and Secure GRDF for a geospatial semanticweb. While we are developing various pieces of technologies, our goal is to work through standardsorganizations such as OGC (Open Geospatial Consortium) and corporations such as Raytheon to transferour research to standards and operational programs. We are members of both OGC and USGIF. We arealso members of UTD’s Geosciences program.Area 3: Data Mining Applications in Security, Funding from Texas Enterprise Funds, NASA,AFOSR (2007 - Present)Our main research in data mining applications is to develop tools for intrusion detection and maliciouscode detection. In addition, we are developing tools for fault detection. We have also applied data miningfor surveillance and biometrics. In the area of surveillance and biometrics, our goal is to developtechnologies for detecting suspicious events. We developed a surveillance system to detect suspiciousevents. We identified normal events and used data mining techniques and determined whether an event issuspicious. In the area of biometrics, we developed tools for face recognition and fingerprint detection. Inaddition, we are conducting research on integrating robotics and security.Area 4: Secure Grid/Cloud and Web Services AFOSR (2008-Present)Here we are developing a delegation model for web services. In addition, we are developing algorithmsfor secure storage of grid systems, as well as accountability policies for grid systems. We have alsodesigned and implemented secure query processing and information sharing in a cloud.Area 5: Secure Social Networks , Funding from AFOSR (2008 - Present),Here we are applying semantic web technologies to represent social networks and investigate security andprivacy (jointly with University of Insubria).Area 6: Complexity Theory (2008 - Present)My PhD research, as well as early research in my career, was in computability theory (please see section3). After 25 years, I have gotten back into the field of co-advising students on complexity theory forsensory networks and security. This is more of a hobby at present.II.Information ManagementSemantic Web: Funding from IARPA (2007 - Present)Our research is in semantic web applications for social networks, as well as knowledge management. Weare conducting research in enhancing JENA, building query techniques with Hadoop, as well asinvestigating security for semantic web and social networks. We are also exploring security for semanticweb and privacy for social networks.18.3 RESEARCH CONTRIBUTIONS TO CS (AUGUST 1980 – SEPTEMBER 2004)My research between 1980 and 2004 proceeded in five main areas: Computability Theory, Data Security,Distributed Processing, Data Management and Information Technologies for Homeland Security.114
Publications: Several journal publications including IEEE Transactions on Knowledge and DataEngineering, IEEE Transactions on Software Engineering, IEEE Transactions on Parallel and DistributedProcessing, Journal of Computer and Systems Sciences, Notre Dame Journal of Formal Logic, Computersand Security and IEEE Computer as well as several conference publications including in ICDE, VLDB,ACSAC, IFIP Data Security, and OOPSLA.Area 1: Computability TheoryMuch of my research in the early 1980s was on computability theory. I studied various decision problemsfor combinatorial systems such as systems functions and proved several results on the unsolvability and thecomplexity of the problems. I also invented the concept of an N-cylinder and this enabled me to giveseveral counter-examples for the complexity problems. I have also applied the results in these papers to mywork on the complexity of the inference problem. This complexity work was stated by NSA (NationalSecurity Agency) to be a significant development in database security in 1990 (Proceedings NationalComputer Security Conference). I am now applying the results to the privacy problem. Several papers werepublished in the Journal of Computer and Systems Sciences and the Notre Dame Journal of Formal Logicbetween 1980 and 1993.Area 2: Secure Data ManagementMy research in information security and secure database systems started in 1985 and still continues.Around 70% of my publications are in this area. This work has had a major impact on the researchcommunity, as well as on the commercial and government communities. I have been invited to givenumerous keynote addresses on my research, as well as advice to the government on information security.My earlier contributions have been on secure relational databases, secure object databases, securedistributed databases and the inference problem. My research in the early 2000s was on secure XMLdatabases, privacy constraint processing, and secure sensor information management. My current researchis discussed in Section 17.2. A summary of my research between 1985 and 2004 is given below.Secure Relational Systems: In the mid to late1980s, I was part of a team at Honeywell designing one ofthe prominent secure relational database systems. This system was called Lock Data Views (LDV) built ontop of a LOCK secure operating system. Issues investigated in this research had an impact on some of thecommercial products that were emerging in the late 1980s and early 1990s. We developed a securitypolicy, security model and designed modules for query, update, and metadata management. We alsodeveloped a multilevel relational data model.Secure Objects: I investigated security for object database systems based on MCC’s ORION. I was one ofthe first to carry out such an investigation. This work had a major impact on the secure database researchcommunity. Subsequently I published a policy, model and design of a system. I also examined the use ofobject models for designing secure systems.Secure Distributed Databases: In the early 1990s, I led a team and conducted research on securedistributed database systems. Algorithms for secure query processing and transaction management weredesigned. Prototypes were implemented. We connected systems in Massachusetts, Washington DC andNew Jersey and built applications. This was a very novel idea at that time. Simulation studies were alsocarried out on secure query and transaction processing.Inference Problem/Secure Deductive Databases: I was one of the first to conduct research on theinference problem and deductive databases and also created a logic for secure databases called NTML(Nonmonotonic Typed Multilevel Logic). I also proved that the inference problem is unsolvable and thiswork was cited as one of the significant developments in database security in 1990 by Dr. John Campbellof NSA in the Proceedings of the 1990 National Computer Security Conference. I was successfully able touse my research on computability theory to study the complexity of the inference problem. I also led a teamthat conducted research on security constraint processing and designed and developed systems to processconstraints. We extended the prototypes to work in a distributed environment.Emerging Security Technologies: More recently my research has been on secure web data management.In particular I have examined security for XML databases and the semantic web. I am also investigating115
