Private itemset support counting (PISC) is a basic building block of various privacy-preserving data mining algorithms. Briefly, in PISC, Client wants to know the support of her i...
Sensor networks are promising unprecedented levels of access to information about the physical world, in real time. Many areas of human activity are starting to see the benefits ...
We study the problem of computing waveletbased synopses for massive data sets in static and streaming environments. A compact representation of a data set is obtained after a thre...
In this paper, we address the maintenance of spatial semijoin queries over continuously moving points, where points are modeled as linear functions of time. This is analogous to t...
We examine the interference of fairness and observers in digital coin systems. Since copying of coins cannot be prevented cryptographically in anonymous off-line coin systems, dou...
