Electromagnetic (electronic) warfare
Electromagnetic radiation (“spectrum”) is essential for modern warfare. What challenges and opportunities does electromagnetic warfare present to the UK?

Biometric technologies identify individuals based on their distinguishing physical and behavioural attributes, such as fingerprints, face, and voice. Unlike passwords or traditional identity documents, biometric attributes are inherently linked to a person and cannot usually be lost or forgotten, potentially providing greater security and convenience. This briefing focuses on how these technologies work, their applications, and the policy challenges raised by their use.
