A Game-Theoretic Investigation of the Effect of Human Interactive Proofs on Spam E-mail

چکیده
We show how a game-theoretic model of spam e-mailing, which we had introduced in previous work, can be extended to include the possibility of employing Human Interactive Proofs (hips) in conjunction with filters that classify incoming messages as legitimate or spam. Using our extended model, we show that making hips widely available to e-mail users will reduce the volume of spam on the Internet and increase the benefit that legitimate users obtain from e-mail.

A New Hybrid Approach of K-Nearest Neighbors Algorithm with Particle Swarm Optimization for E-Mail Spam Detection
Emails are one of the fastest economic communications. Increasing email users has caused the increase of spam in recent years. As we know, spam not only damages user’s profits, time-consuming and bandwidth, but also has become as a risk to efficiency, reliability, and security of a network. Spam developers are always trying to find ways to escape the existing filters therefore new filters to de...
متن کاملA Classification Method for E-mail Spam Using a Hybrid Approach for Feature Selection Optimization
Spam is an unwanted email that is harmful to communications around the world. Spam leads to a growing problem in a personal email, so it would be essential to detect it. Machine learning is very useful to solve this problem as it shows good results in order to learn all the requisite patterns for classification due to its adaptive existence. Nonetheless, in spam detection, there are a large num...
متن کاملNGTSOM: A Novel Data Clustering Algorithm Based on Game Theoretic and Self- Organizing Map
Identifying clusters is an important aspect of data analysis. This paper proposes a noveldata clustering algorithm to increase the clustering accuracy. A novel game theoretic self-organizingmap (NGTSOM ) and neural gas (NG) are used in combination with Competitive Hebbian Learning(CHL) to improve the quality of the map and provide a better vector quantization (VQ) for clusteringdata. Different ...
متن کاملA Game Theoretic Model of Spam E-Mailing
We discuss how the interaction between spam senders and e-mail users can be modelled as a two-player adversary game. We show how the resulting model can be used to predict the strategies that the two opponent communities will eventually adopt, and how it can be employed to tune anti-spam filters.
متن کاملWelfare Impacts of Imposing a Tariff on Rice in Iran vs an Export Tax in Thailand: A Game Theoretic Approach
In this study, the social welfare impacts of the interaction of Iranian rice import policies and Thai export policies are analyzed using a game theoretic approach in conjunction with econometric supply and demand models. The joint impacts of increasing the world price of rice, resulting from the export policies in Thailand along with changes in tariff rates in Iran, on social welfare are analyz...
