Multilevel spam filtering algorithm based on artificial immunity

With the growing use of E-mail, it is urgent to resolve the severe problem of spam. Inspired by the self-protection mechanism of biological immune system, a multilevel spam filtering algorithm is proposed. Experiments on the acquired immune layer have been presented and the results show that the algorithm can get high grade in recall, precision and accuracy of spam filtering. It is also noted that better performance can be achieved by properly arranging the relations between the detector layers.
