Description: The prevention of terrorism through the use of artificial intelligence (AI) technologies has become a crucial topic today. This approach involves the implementation of advanced systems that analyze large volumes of data to identify patterns and behaviors that could indicate terrorist activities. However, this use of AI raises important ethical questions, especially regarding privacy and data protection. Mass surveillance and the analysis of personal data can lead to discrimination and bias, raising concerns about fairness and justice in the application of these technologies. AI’s ability to process information in real-time can be a powerful tool for security agencies, but it can also result in violations of fundamental rights if not implemented with a solid ethical framework. Therefore, it is essential to find a balance between public safety and individual privacy protection, ensuring that the measures adopted do not compromise democratic values or societal trust in institutions. The discussion on terrorism prevention through AI is, therefore, a constantly evolving field that requires critical analysis and a multidisciplinary approach to address its ethical and social complexities.
