In this paper, we present WebGuard, a content protection system for Web documents. WebGuard allows content owners to exercise control over usage conditions governing access to their content. We first introduce the concept of transparent digital rights management, and then show how WebGuard realizes it, using existing Web browsers.

This paper introduces active pedestrian protection system (APPS) project, which was fulfilled during last three years (Nov. 2006 – Oct. 2009) and supported by ministry of knowledge economy (MKE) of Korean government, and then summarizes its achievements. To reduce the number and severity of vehicle-pedestrian accident by active safety vehicle (ASV), false alarm rate should be minimized. For thi...

OF THESIS Privacy Protection for Life-log System Tremendous advances in wearable computing and storage technologies enable us to record not just snapshots of an event but the whole human experience for a long period of time. Such a “life-log” system captures important events as they happen, rather than an after-thought. Such a system has applications in many areas such as law enforcement, perso...

water is a very important vital resource for all living organisms. a world without water can not be imagined. however the world is running out of its most precious resource. water resources must be protected completely before the end of life on earth, so today management of water resources has become the main agenda topic globally. effective protection can be provided by sustainable water manag...

Abstract In response to manufacturing strategy demand, fire accidents in petroleum, chemical, forestry, and high-rise buildings are on the rise. Although firefighting robot can replace rescue workers who come into dangerous site, electronic devices’ thermal failure problem caused by high temperatures whole equipment is bigger. The proportion of device has a significant impact normal operation e...

Once electronic content has been released, it is very difficult to prevent perfect copies of the content from being widely distributed, which can cause economic harm to the content’s owner and others. We focus on content which is to be shared to a limited extent, which is valuable, and which only needs to be protected for a limited amount of time, such as trade secrets. For such content we prov...

This paper describes an application of Sandia's non-contact capacitive sensing technology for collision avoidance during the manufacturing of rocket engine thrust chambers. The collision avoidance system consists of an octagon shaped collar with a capacitive proximity sensor mounted on each face. The sensors produce electric fields which extend several inches from the face of the colIar and det...

As data to be stored in storage subsystems tremendously increases, data protection techniques have become more important than ever, to provide data availability and reliability. In this paper, we present the file system-based data protection (WOWSnap) that has been implemented using WORM (Write-Once-Read-Many) scheme. In the WOWSnap, once WORM files have been created, only the privileged read r...

The Next Linear Collider (NLC) electron and positron beams are capable of damaging the linac accelerating structure and beamline vacuum chambers during an individual aberrant accelerator pulse. Machine protection system (MPS) considerations, outlined in this paper for the 1 TeV NLC design, have an impact on the engineering and design of most machine components downstream of the damping ring inj...
