Abstract—While many protocols for sensor network security provide confidentiality for the content of messages, contextual information usually remains exposed. Such contextual information can be exploited by an adversary to derive sensitive information such as the locations of monitored objects and data sinks in the field. Attacks on these components can significantly undermine any network application. Existing techniques defend the leakage of location information from a limited adversary who can only observe network traffic in a small region. ....etc

Abstract: Watermarking techniques are primarily used for copyright protection. A simple and robust watermark-like digital authentication scheme is proposed. This work has two major merits. First, the watermark used in the proposed authentication scheme is the same type used in the original image, e.g. grey level images. Second the proposed scheme meets the requirements for watermarking techniques. lllegal users cannot perceive and break the watermark signed from the original image. Furthermore, the signed watermark is robust ....etc

Pile driving at large construction sites produces formidable noise. Marine pile driving similarly can produce high sound pressures underwater”but these can be lethal to fish and can harass marine mammals, including those protected by federal law. This problem has contributed to costly construction delays on major bridge projects. To protect marine life, engineers have designed air bubble curtains to reduce underwater sounds. Air provides an effective barrier to sound propagating through water, because of the difference in density betwee ....etc
