MI5, the United Kingdom’s domestic intelligence agency, is harnessing the power of artificial intelligence, aka AI. Specifically, AI is being used to assess whether individuals who watch violent videos online pose a terrorist threat.


  • MI5, the UK’s domestic intelligence agency, is utilizing artificial intelligence to assess if individuals watching violent online videos pose a terrorist threat.
  • Director General Ken McCallum disclosed that MI5 has developed AI tools to analyze suspect’s online video consumption to evaluate potential radicalization and national security risks.
  • The AI tools not only scrutinize video content but also identify violent imagery. This relieves staff from viewing gruesome footage.

How the MI5 is Using AI to Fight Terrorism

Ken McCallum, the director general of MI5, revealed that the agency has developed its own AI tools to analyze online videos being watched by suspects. The aim is to determine whether potential terrorists on the path of violent radicalization present a risk to national security.

These AI tools not only analyze the content of the videos but also detect violence depicted in images. Therefore, the tool spares staff from having to watch gruesome footage. McCallum highlighted the role of mathematics and data science in ensuring the security of the nation during a speech at Glasgow University. He also emphasized that AI advancements are fundamentally changing the world we live in, affecting everyone’s lives.

Additionally, McCallum pointed out the significance of this new tool. He stated that understanding whether an individual actively engaging in extreme right-wing online forums is also consuming extremely graphic violent content can significantly aid in assessing the level of threat they might pose. Moreover, MI5 has taken steps to automate the process of identifying violent content within extensive data streams. As such, this indicates the agency’s commitment to leveraging technology for enhanced security measures.

McCallum also revealed that AI can analyze audio data collected through surveillance activities. This is a crucial aspect of intelligence work. He further mentioned that converting raw audio data into valuable insights has traditionally been a painstaking task. It is one that requires the effort of numerous professionals. With the integration of AI, MI5 aims to automate this process, allowing analysts to focus on higher-level interpretation and decision-making.

Finally, while MI5 is embracing AI technology for its operations, McCallum acknowledged the importance of attracting new talent. He encouraged university graduates interested in defense, security, and AI to consider careers at MI5.
