New approach for secure and efficient metering in the web advertising

In this paper, we present, secure, and efficient metering scheme to measure the number of interactions between clients and servers in the web advertising. In most cases the web advertising consists of advertisers, clients, servers, and an audit agency. The metering scheme should always be secure against fraud attempts by servers, which maliciously try to inflate the number of their visits and Against clients that attempt to disrupt the metering process. We propose secure and efficient metering scheme based on cryptographic techniques. By analyzing the proposed scheme we show that our scheme is more,secure and efficient than previous schemes, [2,3,5].
