Abstract:
1. A data processing system for detecting and correcting malicious nodes in a cloud computing environment, the data processing system comprising: a router configured for communicative coupling to one or more requesting clients over a computer communications network; a master node manager configured for distributing selected tasks to at least one worker node; a suspicion detector comprising program code enabled to select a task to dispatch to a first worker node, to set a suspicion index threshold for the selected task, to determine a suspicion index for the selected task, to compare the suspicion index to the suspicion index threshold and to receive a result from a first worker node; wherein the suspicion detector further comprises program code enabled to select a recovery action; and wherein the suspicion detector further comprises program code enabled to dispatch the selected task to a second worker node, to receive a result from the second worker node, to dispatch the selected task to a third worker node, to receive a result from the third node, to compare the result returned by the first worker node to the result returned by the second worker node and to the result returned by the third worker node and to stop further use of the first worker node when there is a negative match of the result returned by the first worker node to the result returned by the second worker node and to the result returned by the third worker node.
