Abstract. We describe a scheme that secures the remote execution of sequential computations in grid-computing scenarios. To the best of our knowledge, this is the first contributi...
: This paper addresses the security of optimistic fair exchange in a multi-user setting. While the security of public key encryption and public key signature schemes in a single-us...
We construct a financial "Turing test" to determine whether human subjects can differentiate between actual vs. randomized financial returns. The experiment consists of ...
We empirically evaluate several state-of-theart methods for constructing ensembles of heterogeneous classifiers with stacking and show that they perform (at best) comparably to se...
We have used a design science approach to study the collaborative creation of conceptual models. We have designed a collaborative modeling architecture based on business needs and...
