Review of the literature suggests seven fundamental privacy challenges in the domain of ubiquitous social computing. To date, most research in this area has focused on the features associated with the revelation of personal location data. However, a more holistic view of privacy concerns that acknowledges these seven risks is required if we are to deploy(More)
—In this paper we introduce GAFT (Generalized Anomaly and Fault Threshold), featuring a novel system architecture that is capable of setting, monitoring and detecting generalized thresholds and soft faults (network/service anomaly or performance degradations), proactively and adaptively for multiple service classes operating concurrently over the same(More)
This paper introduces a new transmission protocol that uses a joint lossless-source and channel coding scheme (JARQ). This protocol utilizes the self-synchronization property of lossless compression to generate indications of errors in the received data. This approach assures the reconstruction of images that were compressed in a lossless fashion and(More)
In this paper we demonstrate that it is possible in general to detect Windows-based malicious program behavior. Since S. Forrest et al. used the N-grams method to classify system call trace data, dynamic learning has become a promising research area. However, most research works have been done in the UNIX environment and have limited scope. In Forrest's(More)
