Compliant Encryption Of Jpeg2000 Codestreams, Yongdong Wu, Robert H. Deng Oct 2004

Compliant Encryption Of Jpeg2000 Codestreams, Yongdong Wu, Robert H. Deng

Research Collection School Of Computing and Information Systems

This paper presents a compliant encryption method for JPEG 2000 codestreams such that the encryption process does not introduce superfluous JPEG2000 markers in the protected codestream, i.e., the protected codestream preserves the syntax of the original codestream. The proposed encryption method works with any standard ciphers, incurs no storage overhead, introduces negligible computational cost and maintains all the desirable properties of the original JPEG 2000 codestream such as error resilience and scalability.


Flexible Verification Of Mpeg-4 Stream In Peer-To-Peer Cdn, Tieyan Li, Yongdong Wu, Di Ma, Robert H. Deng Oct 2004

Flexible Verification Of Mpeg-4 Stream In Peer-To-Peer Cdn, Tieyan Li, Yongdong Wu, Di Ma, Robert H. Deng

Research Collection School Of Computing and Information Systems

The current packet based stream authentication schemes provide effective and efficient authentication over a group of packets transmitted on erasure channels. However, by fixing the packets in transmission, any packet manipulation will cause authentication failure. In p2p content delivery network where a proxy-in-the-middle is able to store, forward, transcode and transform the stream, previous schemes are simply unapplicable. To address the problem, we propose a flexible verification scheme that relies on special stream formats (i.e. Unequal Loss Protection ULP scheme [7]). We apply the so called Unequal Loss Verification ULV scheme into MPEG-4 framework. The encoding, packing, amortizing and verifying …


Dynamic Access Control For Multi-Privileged Group Communications, Di Ma, Robert H. Deng, Yongdong Wu, Tieyan Li Oct 2004

Dynamic Access Control For Multi-Privileged Group Communications, Di Ma, Robert H. Deng, Yongdong Wu, Tieyan Li

Research Collection School Of Computing and Information Systems

Recently, there is an increase in the number of group communication applications which support multiple service groups of different access privileges. Traditional access control schemes for group applications assume that all the group members have the same access privilege and mostly focus on how to reduce rekeying messages upon user joining and leaving. Relatively little research effort has been spent to address security issues for group communications supporting multiple access privileges. In this paper, we propose a dynamic access control scheme for group communications which support multiple service groups with different access privileges. Our scheme allows dynamic formation of service …


Design And Analysis Of A Cooperative Medium Access Scheme For Wireless Mesh Networks, Arup Acharya, Archan Misra, Sorav Bansal Oct 2004

Design And Analysis Of A Cooperative Medium Access Scheme For Wireless Mesh Networks, Arup Acharya, Archan Misra, Sorav Bansal

Research Collection School Of Computing and Information Systems

This paper presents the detailed design and performance analysis of MACA-P, a RTS/CTS based MAC protocol, that enables simultaneous transmissions in wireless mesh networks. The IEEE 802.11 DCF MAC prohibits any parallel transmission in the neighborhood of either a sender or a receiver (of an ongoing transmission). MACA-P is a set of enhancements to the 802.11 MAC that allows parallel transmissions in situations when two neighboring nodes are either both receivers or transmitters, but a receiver and a transmitter are not neighbors. The performance of MACA-P in terms of system throughput is obtained through a simulation of the protocol using …

Are Use Case And Class Diagrams Complementary In Requirements Analysis? An Experimental Study On Use Case And Class Diagrams In Uml, Keng Siau, Lihyunn Lee Oct 2004

Are Use Case And Class Diagrams Complementary In Requirements Analysis? An Experimental Study On Use Case And Class Diagrams In Uml, Keng Siau, Lihyunn Lee

Research Collection School Of Computing and Information Systems

Despite the status of united modeling language (UML) as the de facto standard for object oriented modeling, it has received controversial reviews. The most controversial diagram in UML is the use case diagram. Some practitioners claim that use case diagrams are not valuable in requirements analysis and some have even argued that use case diagrams should not be part of UML. This research examined the values of use case diagram in interpreting requirements when use case diagrams are used in conjunction with class diagrams. In other words, the study investigated the possible synergetic values and relationships between the use case …


Trust Establishment In Large Scale Grid Settings, Bo Zhu, Tieyan Li, Huafei Zhu, Mohan S . Kankanhalli, Feng Bao, Robert H. Deng Oct 2004

Trust Establishment In Large Scale Grid Settings, Bo Zhu, Tieyan Li, Huafei Zhu, Mohan S . Kankanhalli, Feng Bao, Robert H. Deng

Research Collection School Of Computing and Information Systems

Trust establishment is hard in grid architecture by the ad hoc nature. To set up trust in large scale of network is more difficult. In this paper, we propose an automatic key management (AKM) model and corresponding key construction schemes. The hierarchical structure is formed automatically and scale seamlessly in arbitrary network sized. Regions are configured differently according to various levels of risks faced. The novel model provides an integrated solution for self-organized trust establishment, upon which rich appliances are securely supported. It is automatic, flexible, and scalable. Furthermore, simulation results show that computation costs due to the variations are …

A Novel Log-Based Relevance Feedback Technique In Content-Based Image Retrieval, Steven C. H. Hoi, Michael R. Lyu Oct 2004

A Novel Log-Based Relevance Feedback Technique In Content-Based Image Retrieval, Steven C. H. Hoi, Michael R. Lyu

Research Collection School Of Computing and Information Systems

Relevance feedback has been proposed as an important technique to boost the retrieval performance in content-based image retrieval (CBIR). However, since there exists a semantic gap between low-level features and high-level semantic concepts in CBIR, typical relevance feedback techniques need to perform a lot of rounds of feedback for achieving satisfactory results. These procedures are time-consuming and may make the users bored in the retrieval tasks. For a long-term study purpose in CBIR, we notice that the users' feedback logs can be available and employed for helping the retrieval tasks in CBIR systems. In this paper, we propose a novel …

Leadership Life Skills Demonstrated By State 4-H Council Members, Jacklyn A. Bruce, Barry L. Boyd, Kim E. Dooley

Journal of Extension

The study discussed here examined the demonstration of leadership life skills by former State 4-H Council members. A purposive and snowball sampling technique was used to identify former council members. Traditional qualitative research methodologies were used to collect and triangulate data. The major finding was that State 4-H Council members demonstrated a command of the seven leadership life skill categories. Recommendations include developing a training method to expand the council members' decision-making abilities and the opportunities for them to develop as a group, implement training in personality types and working with different types, and employ new ways of improving communication.

A process for evaluating and improving public domain software is presented for agents and faculty who author software and Web-based training. Extension, education, and conservation employees participated in workshops to learn about a Pasture Land Management System software program that enables farmers to experiment with alternative grazing methods. Users were questioned at initial workshop training and again 6 months later. The workshop evaluation showed concern about the software complexity. The follow-up questionnaire revealed the respondents' priorities for technical improvements. The authors used the participants' feedback to evaluate existing problems and prioritize improvements in the usability and functionality of the software.


Are All These Rules Necessary? Extension Pesticide Programming With A Regulatory Purpose, Jimmy T. Bricker, Andrew G. Martin, Cheri L. Janssen, Fred Whitford Oct 2004

Are All These Rules Necessary? Extension Pesticide Programming With A Regulatory Purpose, Jimmy T. Bricker, Andrew G. Martin, Cheri L. Janssen, Fred Whitford

Journal of Extension

Indiana's private applicator recertification program includes state-required, pesticide regulatory topics. This article explores the relationship between Indiana private applicators' dual attitudes towards pesticide handling practices and the pesticide regulations that mandate those practices. Newly recertified private applicators in northwest Indiana were surveyed by a mailed questionnaire. Respondents valued responsible pesticide management practices, but were collectively undecided about regulatory oversight of their pesticide handling activities. These results suggest that Extension pesticide safety educators involved in compliance education may improve their training curriculum by including material on the underlying benefits, personal and social, of pesticide regulation.


Healthy Living In The Pacific Islands: Results Of A Focus Group Process To Identify Perceptions Of Health And Collaboration In The U.S-Affiliated Pacific Islands, Nicky Davison, Randall Workman, Yihe Goh Daida, Rachel Novotny Oct 2004

Healthy Living In The Pacific Islands: Results Of A Focus Group Process To Identify Perceptions Of Health And Collaboration In The U.S-Affiliated Pacific Islands, Nicky Davison, Randall Workman, Yihe Goh Daida, Rachel Novotny

Journal of Extension

A focus group process was used to gather data on perceptions of health and community collaboration within 6 U.S. affiliated Pacific Islands as part of a process to encourage a community-based participatory approach to addressing community health issues and planning. The focus groups revealed Pacific Islanders' perceptions of health and key local health issues and elements of collaboration. The results were applied to a community-oriented planning process, resulting in the creation of a broad planning framework within which islands could implement their own activities. This approach shows potential for initiating future activities in which communities collaborate in the planning process.

4-H Experiential Education--A Model For 4-H Science As Inquiry, Virginia D. Bourdeau

Journal of Extension

Science education can be improved by immersing learners in the process of using scientific knowledge to "do" science at their 4-H club or school outdoor learning center. In Oregon school-based 4-H programs, the 4-H Science Inquiry in Action model assists volunteers and teachers in moving away from "cookbook experiments" toward learner-centered experiential programs. Using the 4-H Inquiry in Action model, 4-H Agents, leaders, and schoolteachers can make any pre-scripted activity more engaging for youth learners.

Terminating Calder: "Effects" Based Jurisdiction In The Ninth Circuit After Schwarzenegger V. Fred Martin Motor Co., A. Benjamin Spencer Oct 2004

Terminating Calder: "Effects" Based Jurisdiction In The Ninth Circuit After Schwarzenegger V. Fred Martin Motor Co., A. Benjamin Spencer

Faculty Publications

In Calder v. Jones, the Supreme Court clearly and succinctly determined that personal jurisdiction is appropriate over a defendant whose only contact with the forum state is its intentional actions aimed at and having harmful "effects" in the forum state. Illustrating the extent to which the law of personal jurisdiction had been relaxed from the time of Pennoyer v. Neff and International Shoe Co. v. Washington, Calder also extended the reach of state courts by permitting jurisdiction over out-of-state defendants on the strength of the plaintiffs' connections with the forum state. Although Calder provided a welcome and much …
