Spam E-mail Identification Using Blockchain Technology

Over the past few years, there has been an alarming rise in the cyber attacks which are being carried out by Social Engineering Technique. Email is widely used for communication purposes and thus Spam Email Attacks are found to be the most common social engineering technique used by attackers to intrude into the system and perform malicious operations. Almost 85% of the overall email traffic is found to be spam (122.3 billion spam e-mails transmitted per day), which causes severe damage like, data loss, account compromise, ransomware attack, malware infection into the organization/personal systems. Various Artificial Intelligence-based methods (based on reviewing the content of an email) are created to identify spam emails, still, the count of hacks and loss due to spam emails is increasing on daily basis. On the other hand, blockchain being one of the cutting edges and disruptive technology has gained attention in the past few years. In this literature, authors have proposed a blockchain-based system to counter, prevent and identify spam emails. Authors have integrated the wallet-to-wallet transaction in Ethereum, with an existing email system to identify spam and legitimate email. The proposed framework is not based on verifying the content of an email at mailing servers instead the server verifies or check if or not the Cryptocurrency is paid, and thus the proposed framework is supposed to have small workloads and better performance throughput in terms of sending and receiving emails. The authors were able to create a Proof of Concept of the proposed methodology. All the endpoints created to achieve the same were executed in less than 1.5 sec of Elapse Time Average. The proposed framework will act as a Single Source of truth in identifying the Spam E-Mail.
