Events over the past year have demonstrated the utility of mobile devices for coordinating mass gatherings and organizing protests in support of social change. However, governments have countered by censoring or disabling centralized search services and social networking sites. This paper describes a decentralized search and retrieval system, named iTrust,(More)
This paper presents novel statistical algorithms for protecting the iTrust information retrieval network against malicious attacks. In iTrust, metadata describing documents, and requests containing keywords, are randomly distributed to multiple participating nodes. The nodes that receive the requests try to match the keywords in the requests with the(More)
— This paper describes iTrust, a novel distributed search and retrieval system that provides trustworthy access to information over the Internet. Nodes with information to distribute transmit their metadata to nodes that are selected at random from a set of participating nodes. Similarly, nodes seeking information distribute their requests to nodes that are(More)
This paper presents novel statistical algorithms for detecting and defending against malicious attacks in the iTrust information retrieval network. The novel detection algorithm determines empirically the probabilities of the exact numbers of matches based on the number of responses that the requesting node receives. It calculates analytically the(More)
—This paper describes peer management for the iTrust peer-to-peer information publication, search and retrieval system using Wi-Fi Direct in a mobile ad-hoc network. We present the fundamental concept of the iTrust mobile ad-hoc network, the capabilities and limitations of Wi-Fi Direct on the Android platform, and our novel algorithm for managing peer(More)
Treatment of obesity by embedding catgut in acupuncture points has a satisfactory therapeutic effect in many patients. Even though results of its effectiveness are mixed, serious complications are rarely reported with this Chinese traditional therapy. Here an unusual complication of the treatment is reported: multiple tender subcutaneous nodules developed(More)
