Next Generation Email Security: AI Based Spam Detection

This book presents AI-driven approaches for combating spam, phishing, and malware in email systems. It reviews classical techniques, identifies their limitations, and introduces two novel frameworks―FLIDA and G-SFO with adaptive capsule networks. It also highlights the role of quantum machine learning in enabling scalable and resilient email security.

Key Features:

• Concise review of classical and AI-based spam detection.
• Innovative frameworks: FLIDA and G-SFO–ACapsNet.
• Insights into quantum paradigms for cybersecurity.
• Empirical evaluations and comparative performance analyses.
• Open research issues and future perspectives.

This is a valuable resource for researchers, postgraduate students, and professionals in cybersecurity, AI, and data science, as well as industry practitioners and policymakers working on secure communication technologies.
