This paper presents payload inspection for identification of spam files using bloom filter in dual core processor. Spam files flood the Internet in an attempt to dump the messages on recipients who do not intend to receive it. Spam costs the sender very little to send and most of the costs are levied to the recipients or the carriers. The proposed system identifies and filters the incoming spam files using Bloom filter algorithm implemented in dual core processor. The results of the Bloom filter algorithm are examined and these results demonstrate the performance of Sequential Bloom filter and Parallel Bloom filter in a Dual Core Processor.
