The Chaos Computer Club (CCC) has analyzed used US military biometric devices and found large amounts of unencrypted personal data, including names, fingerprints, iris scans, and photographs of over 2,600 Afghans and Iraqis. This data could be life-threatening for the individuals involved if it falls into the wrong hands. The devices were used to identify individuals at checkpoints and control access, and were left behind during the withdrawal of NATO troops from Afghanistan. The CCC is concerned about the irresponsible handling of this sensitive data.
