Abstract
A method and system for auctioning an auction item in a multi-attribute auction. A winning bid is selected by determining a secret value function indicative of acceptable combination of attribute values for the auction owner. The auction owner computing device or the auction server generates alternate combinations of attribute values based at least in part on the secret value function. To generate the alternate combinations of attribute values at least some of the combinations of attribute values are perturbed so as to hinder the bidders from deriving or finding the secret value function. The auction server informs the bidders, via a bidder interface of a client computing device, about the alternate combinations of attribute values and required biding directions. The bidder can offer a bid in a next round based on the alternate combinations of attribute values, in a progressive manner and without knowledge of the secret value function.
