A web-computing system (WCS) allows a host with limited resources to perform CPU intensive tasks by outsourcing the computations to external clients. But not every client is trusted, and redundancy in task assignment and auditing of results are needed to ensure the integrity of the results. This raises the question as to the efficiency and reliability of the system as measured against a given unit of the host's auditing time or cost. In this paper we propose a WCS with low overhead and has favorable error rate compared to a majority-voting scheme with similar efficiency. We can reduce the error rate by re-authenticating the results without having to resubmit any jobs, and we have an auditing strategy that in many cases is probabilistically better than random sampling.
